Abstract
Description
Technical Field
[0001] A system for storing electrical energy using readily available resources such as gravity, water, underground minerals, suspending agents, chemical dispersants and / or optional additives, mixing equipment for mixing components, elevated water storage devices such as water towers, a turbine generator for generating alternating current or direct current, and a pump for returning the mineral suspension to the elevated water storage device to charge a battery. Background Technology
[0002] Humans have been using renewable energy sources to generate electricity for over a century. Hydroelectric dams still produce a significant amount of electricity worldwide, but they require damming free-flowing rivers to generate sufficient head pressure to power turbine generators. Damming rivers has a severe impact on wildlife, fish, and the human environment, depriving them of valuable resources.
[0003] The conveniences of industrialization and modernization have created a high demand for electricity. Fossil fuels such as coal, oil, and natural gas are used to generate electricity with greater capacity and voltage. Human societies have begun to rely on low-cost electricity supplies to meet industrial production and household / consumer needs. This reliance has driven demand for drilling in coal, oil, and natural gas mines. The global supply system, which consumes fossil fuels, transports these materials to power plants, where hydrocarbon energy is converted into electricity.
[0004] Coal mining and oil and gas production can damage the environment in a variety of visible and invisible ways. Vast amounts of coal are mined in open pits, leaving millions of acres of damaged land. Overburden heaps from coal mines pollute creeks and rivers through acidic runoff. The environmental impacts of fossil fuel production are visible to the naked eye.
[0005] It is the intangible impact of burning fossil fuels that affects the lives of humans and animals. Burning fossil fuels produces greenhouse gases, leading to rising global temperatures. Combustion gases may contain acidic substances that can damage forests and crop production. Coal combustion produces and stores ash, which must be stored on-site. The storage of ash poses environmental risks for thousands of years due to potential groundwater and surface water contamination.
[0006] Transportation systems generate millions of tons of greenhouse gases daily by burning gasoline and diesel fuels in internal combustion engines. Hydrocarbon refining systems add further greenhouse gases during fuel production. Human-caused greenhouse gas emissions contribute to rising global temperatures and the melting of glaciers and polar ice caps.
[0007] To mitigate and ultimately halt this ongoing environmental damage, people around the world have called for action to increase the use of renewable energy. Renewable energy has a far lower environmental impact than energy generated from fossil fuel sources. Increasing the use of renewable energy requires large energy storage capacity to reduce its cost and increase its viability as a fossil fuel alternative. Large storage capacity must be established before renewable resources can be fully utilized to realize their potential.
[0008] Solar and wind power are two of the most commonly used energy sources. They are variable because, in a given day, the sun shines for 12 hours or less, and the stored energy must be used for the remaining 12 hours. Wind power is intermittent, with peak and trough energy production that does not align with electricity demand.
[0009] Currently, the methods for storing and replenishing wind and solar energy involve using chemical batteries, such as lithium-ion and sodium-ion batteries. Both systems require electricity from the grid to charge. Lithium-ion batteries are prone to explosions and thermal runaway events, which are often difficult to extinguish using conventional methods. Sodium-ion batteries are considered safer, but they are not entirely risk-free. Like any energy storage system, they can still experience thermal problems, short circuits, or other malfunctions that could lead to overheating. However, the risk of explosion is generally lower compared to lithium-ion batteries. Placing these batteries in densely populated urban environments poses a significant risk to local residents. Placing them in rural or remote areas would require substantial resources to deal with potential fires and explosions.
[0010] Manufacturing high-density batteries that are environmentally friendly and organized in a way that meets the requirements of renewable energy systems is highly desirable and will make renewable energy the norm rather than the exception. Increasing electricity storage capacity will help facilitate the use of renewable energy.
[0011] Therefore, the main objective of this invention is to store electrical energy using readily available resources.
[0012] This is achieved through the embodiments described in this specification. Summary of the Invention

[0018] Aspects of the invention include solid particles defined as solid particles (%w / w) comprising 5% to 95% of the total weight of the aqueous liquid plus the dry weight of the solid particles.

[0020] The invention includes aspects of a generator that is stationary or portable; selected from stationary or portable hydroelectric generators, such as portable hydroelectric generators, optionally mounted on a vehicle, such as a vehicle used to serve other vehicles (e.g., a trailer) (including electric vehicles, such as electric vehicles whose battery stores less than 90%, 80%, 70%, 60%, 50%, 40%, 30%, 20%, 10%, 5%, or 1% of the electric vehicle's battery storage capacity); and combinations thereof.
[0021] The invention includes aspects in which the one or more loads are selected from batteries, such as: batteries in vehicles, including electric vehicles, including electric cars; batteries in homes, including batteries for household appliances (e.g., large computer storage facilities); batteries in buildings, including batteries for storing electrical energy for peak use or power outages; batteries in inverters for converting alternating current to direct current and vice versa; batteries in alternating current generators for generating alternating current; batteries in transformers; and combinations thereof. Optionally, one or more loads are connected to a power grid, a distribution network, such as residential (including individual residences), commercial (including individual commercial structures, such as buildings), transmission lines, or combinations thereof.
[0022] The invention also includes storing an aqueous suspension of solid particles in one or more portable or stationary containers prior to flow for supplying fuel to a generator to generate electricity.
[0023] Aspects of the invention include one or more containers having a capacity of 200 to 2,000,000 gallons. The lower limit of this range is 200, 500, 1,000, 5,000, or 10,000 gallons. The upper limit of this range is 50,000, 100,000, 200,000, 500,000, 1,000,000, 1,500,000, or 2,000,000 gallons. Any combination of the lower and upper limits of this range is possible. Aspects of the invention include one or more containers that are open (e.g., for air) containers or closed containers (e.g., pressurized gas, for example by an air compressor, such that the gas (e.g., air) occupies a portion of the closed container, thereby promoting flow; or one or more containers for municipal, industrial, residential, commercial, agricultural purposes or a combination of the above purposes, such as towers or barrels; or for commercial purposes, optionally mounted on a vehicle, for example for servicing other vehicles (including electric vehicles, such as electric vehicles whose battery stores less than 90%, 80%, 70%, 60%, 50%, 40%, 30%, 20%, 10%, 5%, or 1% of the electric vehicle's battery storage capacity; or combinations thereof (or having any capacity)) vehicles (e.g., trailers).
[0024] Aspects of the invention include flow aided or caused by one or more of the following: gravity; pressure, such as air pressure above an aqueous suspension of solid particles in a closed container; a pump, such as a positive displacement pump or a piston pump; and combinations thereof. Aspects of the invention also include containers configured with alternative energy sources, including, for example, solar panels or windmills associated with generators of alternative energy sources.

[0026] The system can be configured to generate alternating current for distribution to the grid when renewable resources are scarce, undesirable, or unavailable (e.g., when there is no solar power at night, or when wind power is insufficient or unable to power wind turbines).
[0027] The system can be configured to generate direct current to charge, for example, cars and trucks, with a charging efficiency that is more efficient than charging from the grid using alternating current, for example, when the conversion from alternating current to direct current results in a power loss of up to 30%.
[0028] This system can be configured to charge while discharging. For example, alternating current or stored pneumatic pressure can be used to drive a pump to charge the battery, while a turbine generator produces direct current or alternating current for industrial use, such as charging a large fleet of electric vehicles, computer facilities, etc. Renewable energy grid systems cannot sustainably meet this demand.
[0029] This system can be configured and deployed in densely populated areas with minimal or even zero risk of fire or explosion. The minerals and chemicals used are relatively non-toxic and can be reused for other purposes after replacement. Construction in local communities, commercial, and industrial facilities will eliminate the long-distance transmission losses currently associated with grid power. It will also increase the proportion of sustainable, locally generated clean energy.
[0030] Multiple systems can be used to balance grid power and maintain the balance of the power system, regardless of whether fossil fuel sources need to be called upon to compensate for differences in power load demand.
[0031] The system can be located within or as part of a building or other structure, or it can be transported to a remote location by vehicle.

[0039] A system comprising fuel configured to flow to a generator to produce electricity, which can be used to power loads including resistive, capacitive and inductive loads.
[0040] A method for generating electricity in which fuel flows to a generator to produce electrical energy. The generated electrical energy is transmitted directly or indirectly to one or more loads. The fuel comprises an aqueous suspension of solid particles in an aqueous liquid. Aqueous suspensions of solid particles in aqueous liquids
[0041] An aqueous suspension of solid particles includes solid particles in an aqueous liquid, optionally containing at least one mineral suspending agent and / or optionally at least one dispersant and / or optionally at least one additive in the dispersed phase and / or liquid phase.
[0042] As used in this application, the suspension is an aqueous liquid in which solid particles are dispersed. Aqueous liquids
[0043] In some embodiments of the aqueous suspension, the aqueous liquid is water. In some embodiments of the aqueous suspension, the aqueous liquid includes water and optionally at least one other liquid. In some embodiments of the aqueous suspension, the amount of water present is greater than 50% v / v relative to the total volume of water plus at least one other liquid. In some embodiments, this amount is greater than 60% v / v, 70% v / v, 96% v / v, or 99% v / v. In some embodiments, this amount ranges from 75% to 95% v / v or 80% to 90% v / v.
[0044] Optionally, the aqueous liquid contains at least one other solid substance, for example, at least one other solid substance miscible with the components of the aqueous liquid phase, such as water. Alternatively, at least one other solid substance is miscible with the components of the aqueous liquid phase. For example, at least one other solid substance is added to the water source or during the collection of solid particles.
[0045] In some embodiments, at least one other liquid is an organic liquid. In some embodiments, the organic liquid is selected from silicone resins, hydrocarbons, and alcohols. In some embodiments, the organic liquid is derived from tar sands, oil sands, and lignite. In some embodiments, the organic liquid is selected from ethylene glycol or silicone. In some embodiments, at least one other liquid is miscible with water or at least partially miscible with water. In some embodiments, at least one other liquid is extracted, for example, during the collection of solid particles. In some embodiments, at least one other liquid is added, for example, through processing steps before or after the extraction of solid particles or for any other reason.
[0046] Water can be obtained from many sources. In some embodiments, the water comes from a freshwater source or a saltwater source. In some embodiments, the water is brackish or saltwater. In some embodiments, the water comes from a source selected from saltwater ponds, seawater, ocean water, lakes, ponds, and groundwater. For example, a brackish or saltwater source includes sources selected from saltwater ponds, seawater, ocean water, lakes, ponds, municipal water, tap water, and groundwater.
[0047] The density of pure water is approximately 1.0 g / cm³. The density of water does not change substantially when the temperature is below its boiling point of 100°C or at standard atmospheric pressure. In all cases, the reference point is 4°C (39°F), as water has its highest density at this point, at 1000 kg / m³.
[0048] Specific gravity, or relative density (SG), is defined as the ratio of the density of a substance to the density of water at a specific temperature, and can be expressed as: SG=ρ substance / ρ H2O Where SG = specific gravity of the substance; ρ substance = Density of fluid or substance [kg / m³] 3 ]; ρ H2O = Density of water - typically at a temperature of 4°C [kg / m³] 3 ];
[0049] The reference density of water at 4°C (39°F) is usually used as a reference because this is when water has the highest density, at 1000 kg / m³. 3 Since specific gravity (SG) is dimensionless, it has the same value in both the International System of Units (SI) and the Imperial System (BG). The SG of a fluid has the same numerical value as its density, expressed in g / mL or Mg / m³. 3 It is indicated by water. Water is usually used as a reference when calculating the specific gravity of solids.
[0050] Water is generally considered a Newtonian fluid, meaning that shear stress is linearly proportional to the shear rate (viscosity). Viscosity is constant.
[0051] Solids dissolved in aqueous liquids tend to increase the specific gravity of the liquid. For example, if the density of salt water is 1200 kg / m³... 3 The specific gravity is 1.200.
[0052] The percentage of solid particles, such as minerals, suspended in water (e.g., a slurry) is referred to as the suspended solids percentage. Optionally, the minerals can also be solids dissolved in water, such as calcium chloride (salt) and other soluble minerals. Solid minerals can be suspended in water or aqueous liquids using suspending agents. Adding minerals with a higher specific gravity increases the density of the water (aqueous) / slurry. In other words, an aqueous suspension of solid particles in an aqueous liquid is:
[0053] For example, the calculation for water / slurry is shown below.
[0054] The density of the slurry can be calculated as follows: ρ m =100 / [c w / ρ s +[100-c w ] / ρ l (1) in, ρ m = Density of slurry (lb / ft) 3 kg / m 3 ); c w = Weight concentration of solids in the slurry (%); ρ s = Density of solids (lb / ft) 3 kg / m 3 ); ρ l = Density of a liquid that does not contain solids (lb / ft) 3 kg / m 3 ). The weight concentration of a slurry can be measured by evaporating a known weight of the slurry and measuring the weight of the dried solids.
[0055] The density of the solid is 2500 kg / m³. 3 The density of the liquid is 1000 kg / m³ 3 The density of a slurry with a solids concentration of 30% can be calculated as ρ. m =100 / [(30%) / (2500kg / m 3 )+[(100%)-(30%)] / (1000kg / m 3 )]=1220kg / m 3 .
[0056] The density of the solid is 2500 kg / m³. 3 The density of the liquid is 1000 kg / m³ 3 The density of a slurry with a solids concentration of 70% can be calculated as follows:
[0057] ρ m=100 / [(30%) / (2500kg / m 3 )+[(100%)-(70%)] / (1000kg / m 3 )]
[0058] =2161kg / m 3 .
[0059] Compared to 30% slurry, its density increased by 77%, and compared to the density of water, its density increased by 216%. solid particles
[0060] Solid particles, such as minerals, suspending agents and / or dispersants, as well as other dense solids, tend to make the flow characteristics of water or aqueous liquids more non-Newtonian, meaning that viscosity does indeed depend on stress and flow changes under force.
[0061] The specific gravity of the solid particles ranges from 0.9 g / cm³. 3 Up to 6g / cm 3 1.9g / cm 3 Up to 6.0 g / cm 3 2.5g / cm 3 Up to 5.5 g / cm 3 Or 3.4g / cm 3 Up to 4.8 g / cm 3 .

[0129] In some embodiments, the wetting / dispersant foams little to no in water and has a structure including an organic portion capable of adsorbing onto the surface of suspended solid particles. For example, if the solid particles comprise organic particles (e.g., coal, peat, etc.), the wetting / dispersant has an electrically charged hydrophilic portion compatible with the continuous phase (e.g., water). For example, if the solid particles comprise inorganic particles, the wetting / dispersant has an organic portion capable of adsorbing onto the surface of inorganic particles (bauxite, iron ore, sand, copper, molybdenum, talc, titanium dioxide, calcium carbonate, potash, other industrial minerals, etc.) and an electrically charged hydrophilic portion compatible with the continuous phase (e.g., water).

In some embodiments, stirring is carried out in the presence of one or more additives. In some embodiments, stirring is carried out in the presence of at least one wetting / dispersing agent and / or at least one clay dispersing agent.
[0137] The aqueous liquid, solid particles, and at least one mineral suspending agent are mixed in any order.

[0138] In some embodiments, both an aqueous liquid and solid particles are added to at least one mineral suspending agent. In some embodiments, both a mineral suspending agent and solid particles are added to an aqueous liquid.
[0139] In some embodiments, agitation is sufficient to substantially homogenize the aqueous suspension. In some embodiments, agitation is sufficient to homogenize the aqueous suspension. In some embodiments, homogenization enables solid particles to settle in a manner inconsistent with what Stokes' law of sedimentation predicts.
[0140] In some embodiments, the aqueous suspension is a heterogeneous aqueous suspension.
[0141] In some embodiments, stirring is mechanical. In some embodiments, stirring is selected from agitation, pumping, and grinding. In some embodiments, the amount of solid particles present is sufficient to exert shear force on the aqueous liquid and promote homogenization of the aqueous suspension. In some embodiments, stirring is the result of concrete drilling, ultrasonic dispersion, or cavitation.
[0142] In some embodiments, the mineral suspending agent is added in the form of powdered clay. In some embodiments, the powdered clay is dried before being added.
[0143] In some embodiments, the mineral suspending agent is added in the form of a pre-gel consisting of at least one mineral suspending agent and water. In some embodiments, the pre-gel consists of at least one mineral suspending agent at a weight percentage of 1% to 15% and the remainder water. In some embodiments, the pH value of the water is selected from values disclosed herein for the liquid phase of aqueous suspensions. In some embodiments, the water includes at least one neutralizing agent selected from neutralizing agents disclosed herein for the liquid phase of aqueous suspensions.
[0144] In some embodiments, the mineral suspending agent is added in the form of a pre-dispersion consisting of at least one mineral suspending agent, a clay dispersant, and water. In some embodiments, the pre-dispersion consists of 1% to 45% by weight of at least one mineral suspending agent, 0.05% to 1.0% by weight of a clay dispersant, and the remainder water.

[0147] In some embodiments, the aqueous suspension is prepared by the following steps: adding a clay dispersant and clay to an aqueous liquid while stirring and continuing to stir until the clay is dispersed to form a pre-dispersion, thereby preparing a mineral suspension in the form of a pre-dispersion; adding a dispersant for at least one mineral suspension to the aqueous liquid; adding the mineral suspension in the form of a pre-dispersion to the aqueous liquid; and adding solid particles while stirring. To make the aqueous suspension flow
[0148] Fuel flowing to a generator can potentially generate electricity. The generator can be stationary or portable; selected from stationary or portable hydroelectric generators, such as portable hydroelectric generators, optionally mounted on vehicles, such as for servicing other vehicles (including electric vehicles, such as electric vehicles whose battery stores less than 90%, 80%, 70%, 60%, 50%, 40%, 30%, 20%, 10%, 5%, or 1% of their battery storage capacity) (e.g., trailers); and combinations thereof.
[0149] Therefore, the generated electrical energy is transmitted directly or indirectly to one or more loads. The one or more loads are selected from batteries, such as: batteries in vehicles, including electric vehicles, including electric cars; batteries in homes, including batteries for household appliances (e.g., large computer storage facilities); batteries in buildings, including batteries for storing electrical energy for peak use or grid outages; batteries in inverters for converting AC to DC and DC to AC, batteries in alternators for generating AC; batteries in transformers; and combinations thereof. Optionally, said one or more loads may be connected to a power grid, a distribution network, such as residential (including individual residences), commercial (including individual commercial structures, such as buildings), transmission lines, or combinations thereof.
[0150] Aqueous suspensions enable long-distance mineral transport, which means that fuel consumption will increase (based on the increased specific gravity relative to the aqueous liquid itself) and the electrical energy generated by the generator. Transport is facilitated by adding an effective amount of at least one mineral suspending agent.
[0151] Solid particles in an aqueous suspension can flow toward or through two or more generators arranged in series and / or parallel.
[0152] In some embodiments, the solid particles are transported over a distance greater than or equal to 50 m. In some embodiments, this distance is greater than or equal to 0.600 km, 5 km, or 10 km. In some embodiments, this distance ranges from 40 km to 500 km, 100 km to 420 km, or 200 km to 380 km.
[0153] In some embodiments, transport includes flowing an aqueous suspension of solid particles in a conduit. In some embodiments, the conduit includes a pipeline, weir, U-shaped structure, mobile conveyor, and other structures for transporting water over a distance greater than 50 m. In some embodiments, the inner diameter of the pipe in the pipeline is at least 1.28 cm, 5 cm, or 300 cm. In some embodiments, the inner diameter of the pipe ranges from 1.28 cm to 200 cm, 5 cm to 100 cm, or 10 cm to 75 cm. In some embodiments, the conduit, pipeline, U-shaped structure, weir, mobile conveyor, and other structures for transporting water over a distance greater than 200 m have a lateral dimension of at least 1.28 cm, 5 cm, or 100 cm. In some embodiments, the lateral dimensions of the conduit, pipeline, U-shaped structure, weir, mobile conveyor, and other structures for transporting water over a distance greater than 50 m range from 1.28 cm to 300 cm, 10 cm to 200 cm, or 75 cm to 150 cm. The conduit may be configured to couple to allow fuel to flow through a generator.
[0154] In some embodiments, transport includes flowing an aqueous suspension of solid particles in a conduit such that the solid particles are transported over a distance. In some embodiments, transport includes flowing an aqueous suspension of solid particles in a conduit such that the solid particles are transported over a distance of at least 10m, 20m, 50m, 100m, or 1000m.
[0155] In some embodiments, transport includes pumping an aqueous suspension. In some embodiments, gravity and the placement of conduits further facilitate transport.
[0156] For example, aqueous suspensions (flowable slurries / mineral suspensions) can be lifted from the ground to almost any height by using pumps specifically designed for pumping mineral slurries. These pumps are described as centrifugal pumps, positive displacement pumps, and piston pumps. Other pumps not described may also be used. The size and horsepower of the pump depend on the specific gravity of the liquid and the height the mineral suspension is lifted. Compressed air can be used to assist the pump to reduce the cost of pumping aqueous suspensions to elevated tanks.
[0157] In some embodiments, the solid particles are transported back and reused via the same generator, for example using gravity and / or the pumps mentioned in this application. For example, water or slurry can be raised and stored in a tower for future release into a turbine generator to generate electricity.
[0158] In some embodiments, the aqueous suspension is stored in a container suitable for storing an aqueous suspension of solid particles. In some embodiments, the container is selected from conduits and transport containers (vehicles). In some embodiments, the transport container is selected from intermodal cargo containers, medium bulk transport containers, drums, containerized equipment, and dedicated transport containers suitable for aqueous suspensions of solid particles. Water storage towers are common in municipal, industrial, and agricultural applications. Water is pumped to the tower, and the resulting head pressure is used to supply water to the system being served at a relatively constant head pressure. For fluctuations in head pressure or turbidity in the fuel stream, a flywheel can be used to suppress fluctuations in the electricity generated by this method. In this invention, the slurry can be pumped and stored in the tower for future release into a turbine generator to generate electricity.
[0159] In some embodiments, one or more containers have a capacity ranging from a lower limit to an upper limit, wherein the lower limit is independently selected from 200, 500, 1000, 5000, or 10000 gallons, and the upper limit is independently selected from 50000, 100000, 200000, 500000, 1000000, 1500000, 2000000, or 4000000 gallons, for example, 200 to 50000 gallons, 10000 to 2000000 gallons, 1000 to 1000000 gallons, or 2000000 to 4000000 gallons. In some embodiments, one or more containers are open (e.g., for air) containers or closed containers (e.g., pressurized gas, such as by means of an air compressor, such as air occupying a portion of the closed container to facilitate flow). In some embodiments, one or more containers are used for municipal, industrial, residential, commercial, agricultural purposes, or a combination of the above purposes, such as towers or barrels. In some embodiments, one or more containers are used for commercial purposes and may be optionally mounted on vehicles, such as for servicing other vehicles (including electric vehicles, such as electric vehicles whose battery storage capacity is less than 90%, 80%, 70%, 60%, 50%, 40%, 30%, 20%, 10%, 5%, or 1%) (e.g., trailers). In some embodiments, one or more containers are combinations thereof. In some embodiments, the containers are configured with alternative energy sources, including, for example, solar panels or windmills associated with generators for alternative energy sources.
[0160] For example, a 2,000,000-gallon container can produce approximately 8.7 MW of iron ore in 2-3 hours. A 1,000,000-gallon or 500,000-gallon container will produce 1 / 2 or 1 / 4 of the wattage in the corresponding time.
[0161] In some embodiments, the flow is facilitated or caused by one or more of the following: gravity; pressure, such as air pressure above the aqueous suspension of solid particles in a closed container; a pump, such as a positive displacement pump or a piston pump; and combinations thereof. In some embodiments, the solid particles of the aqueous suspension are returned to the same or different containers for reuse via the same or different generators or another set of generators. load
[0162] As mentioned above, the load can be resistive, capacitive, or inductive.
[0163] In some embodiments, the power generation is used for one or more of the following: charging residential AC outlets, such as 110V, 220V, 440V or combinations thereof; DC fast charging (DCFC), such as along corridors, optionally at fixed stations, private or public places, including shops (grocery stores, merchandise stores, service stores, etc.), theaters, coffee shops, and combinations thereof; DCFC for batteries of communities or electric vehicles, such as along highways and roads, optionally via battery towers; for peak use in communities, such as to alleviate peak use of electricity on sources such as the power grid; or in conjunction with other renewable energy sources such as solar, wind, natural gas, coal or nuclear power.
[0164] It's important to emphasize that part of the reason diesel trucks exist is the inability to build charging stations. Chargers are expensive, and gas stations (diesel refueling stations) are not substations. Therefore, under the current circumstances, it seems impractical to have no alternative for electric trucks and vehicles. For convenience, placing the system at truck stops or gas stations seems preferable.
[0165] Figure 1A A system and method are illustrated. The fuel is fuel flowing to a generator to generate electricity for one or more loads.
[0166] Figure 1B A system and method are illustrated. Fuel 10 is added to a container 20 for storing fuel 10 so that it flows through a conduit 25 to one or more power sources 30 connected in series or parallel, or a combination thereof. The electricity can be used to supply loads 40 and / or to the power grid, which can be used to supply additional loads 43. The fuel flowing to generate electricity is recyclable fuel 15, which is returned to container 20 via a return conduit 27 for reuse.
[0167] The method and system used as an alternative power source have been disclosed.
[0168] Example
[0169] Theoretically, the energy that water can gain upon falling can be expressed as follows: P th =ρqgh. in, P th =Theoretical available power (W); ρ = density (kg / m³) 3 (Water is approximately 1000 kg / m³) 3 ); q = water flow rate (m) 3 / s); g = gravitational acceleration (9.81 m / s²) 2 ); h = Falling height, head (m). Example - Hydropower
[0170] Theoretically, the flow rate is 1m 3 The power that can be provided by a water drop of 100m per second can be calculated as follows: P = (1000 kg / m³) 3 (1m) 3 / s)(9.81m / s 2 (100m) =981000W = 981kW / sec. By using 5200 kg / m 3 The density of water is increased by suspending hematite minerals, as shown above: P = (2353 kg / m³) 3 (1m) 3 / s)(9.81m / s 2 (100m) =2308kW / sec. Compared to hydropower, the power generation is increased by 235%. Therefore, in this example, the battery's storage density is 235% higher than that of an equal volume of water.
[0171] Water towers and reservoirs can be designed in various forms. A typical large water tower can store 7,570 cubic meters of water (2 million US gallons). If a water tower can store 7,570 cubic meters of hematite slurry and supply it to a generator at a feed rate of 1 cubic meter per second, it can generate 8.308 megawatts per hour. At a feed rate of 1 cubic meter per second, 7,570 cubic meters of mineral suspension will supply the turbine for 126 minutes (2.10 hours). The total energy stored in the 7,570 cubic meter reservoir will reach 17.446.8 megawatts within 126 minutes.
[0172] The same water tower can generate 3.531 megawatts of electricity per hour, or 7.416 megawatts of electricity in 126 minutes.
[0173] This type of system can be built as a standalone storage facility or integrated into the construction of high-rise buildings or residences, for example, as emergency power storage. Grid operators can manage multiple systems (through software or artificial intelligence) to balance local or regional short-term demand during peak periods.
[0174] It is foreseeable that electricity supplied from one or more systems to meet peak demand will be sold at peak demand rates, resulting in a higher return on investment for the systems. Systems can be charged during periods of lower grid demand. Recharging of systems can sometimes be achieved by pumping stored mineral suspensions to higher storage points or by using pumps or gravity (from higher to lower locations) to redirect them to another generator. Charging electric vehicles used for transportation will place significant demands on the grid. As more electric vehicles enter transportation networks, the energy consumed in charging lithium-ion batteries is substantial. It is estimated that 504 megawatts of electricity would be needed in the United States alone to convert highway truck traffic from diesel power to lithium-ion stored electrical energy. This will require new renewable generation capacity, as clean energy stored in batteries, to be distributed to these vehicles through the grid system / region. This estimate does not include automobiles.
[0175] Charging electric vehicles used for transportation will place high demands on the power grid. As more and more electric vehicles enter the transportation network, the energy consumed in charging lithium batteries is enormous. Passenger vehicle charging is categorized into the following three levels.
[0176] Level 1
[0177] Level 1 devices are charged via a standard residential 120-volt (120V) AC outlet. A Level 1 charger may take 40-50+ hours to charge a BEV (Battery Electric Vehicle) from empty to 80%, while a PHEV (Plug-in Hybrid Electric Vehicle) may take 5-6 hours.
[0178] Level 2
[0179] Level 2 devices provide higher-speed AC charging via 240V (in residential applications) or 208V (in commercial applications) power services and are commonly used in homes, workplaces, and public charging facilities. A Level 2 charger can charge a BEV to 80% in 4-10 hours and a PHEV to 80% in 1-2 hours.
[0180] DC Fast Charging (DCFC)
[0181] DC Fast Charging (DCFC) equipment provides fast charging along busy corridors of the installed stations. DCFC equipment can charge a BEV to 80% in just 20 minutes to 1 hour.
[0182] Level 2 and DCFC devices have been deployed in various public places, such as grocery stores, theaters, or coffee shops, which places high demands on the power grid system.
[0183] Current grid-powered DCFC systems are inefficient at converting AC (alternating current) power to DC (direct current) power. The concept of battery towers using locally generated electricity can produce DC power for fast charging of vehicles at truck docks or direct connection to local communities. This system can significantly reduce the electricity demand on the renewable energy grid. Direct connection to home charging stations operating on DC will lower costs for consumers, making electric vehicles more affordable.
[0184] Because many modern devices operate internally as direct current (DC), alternating current (AC) is subsequently converted back to DC via each device's adapter. This double energy conversion, which results in up to 30% energy loss, can be eliminated if the building's power distribution is converted to DC. Battery designs will then allow them to discharge at DC, which is more efficient for charging car and truck batteries.
[0185] For example, in high-rise buildings, one or more elevators generate pressurized air that can be used to move fuel to, for example, higher levels for use or to generate electricity. Containers within the building are located on, for example, higher floors, where gravity can be used to generate electricity.
[0186] For example, in a residence, a pump can be used to flow fuel to, for example, a high place (e.g., an attic or roof) for use or to generate electricity. Containers in a residence may be located in places where gravity can be used to generate electricity, for example, when needed (e.g., in a shortage or emergency) or when desired (e.g., during peak demand periods from the relevant power grid).
[0187] The production of renewable energy varies depending on the availability of sunlight or wind. The availability of renewable energy does not always meet the needs of the energy grid.
[0188] This system and method can be used from other sources, whether or not they are renewable.
[0189] Solar energy is only available for a limited number of hours each day. When there is no sunlight, grid demand can peak. Weather conditions can inhibit solar energy collection, making large-scale storage even more necessary for the use of solar energy. Figure 2 This indicates the time shift of solar energy.
[0190] Wind energy is more stable than solar energy, but it still has the same problems associated with the variability of wind or the complete absence of wind to drive wind turbines. Figure 3 This indicates a constant output of wind energy.
[0191] As systems become increasingly complex, they become more suitable for control by artificial intelligence computer systems. For example, in some embodiments, algorithms may extrapolate, interpolate, or otherwise simulate the electricity use of one or more electricity consumers or systems. The algorithm outputs, the model, and the results of applying the algorithm to a dataset are considered. These models can automate decision-making through artificial intelligence. In some cases, these models are machine learning models trained on a sample dataset that serves as the basis for real-world predictions. While supervised machine learning (classical machine learning) is possible, unsupervised or reinforcement-based machine learning tends to be a way to automate large numbers of consumers and energy grids. Open-source machine learning frameworks are available.
[0192] Example
[0193] A structure comprising a container capable of storing 1000 gallons of aqueous suspension. Iron ore (72% by weight of the suspension) and... (0.04% by weight of iron ore) is added to a container along with water, either for immediate use or for storage. When electricity is needed or desired, the aqueous suspension flows through pipes with an inner diameter of 1-3 inches to a generator, which powers the load, charges the lithium-ion battery, and adds unused electricity to the grid. During peak hours (utility charges), the battery powers the structural load. During off-peak hours, a pump transports the aqueous suspension to the original container or a second container. The second container is either of the same or different structural design. The aqueous suspension in the second container can then be used to fuel another generator, thus powering the same or other loads. In this sense, this example represents a container network and generators that can be used to power various loads in the same or different structural designs. Maintaining a smaller distance between the generator and the load is more efficient than grid-powered loads and prevents the energy losses inherent in long-distance power transmission.
[0194] Example
[0195] A multi-layered structure with a container capable of storing 10,000 gallons of aqueous suspension. Iron ore (88% by weight of the suspension) and... (0.10 w / w% of iron ore) is added to a container along with water, either for immediate use or for storage. When electricity is needed or desired, the aqueous suspension flows under gravity through pipes with an inner diameter of 2-6 inches to a generator, which powers the load and charges rare-earth batteries and / or lithium-ion batteries. During peak hours (utility electricity rates), the batteries are used to power the building's loads, or the fuel flows under gravity to a second generator located on a lower floor. During off-peak hours, a pump transports the aqueous suspension to either the original container or a second container (on the same floor). The second container is either of the same or different construction. The aqueous suspension in the second container can then be used to fuel another generator, thus powering the same or other loads. In this sense, this example is a network of containers and generators that can be used to power various loads in the same or different constructions. Maintaining a smaller distance between the generator and the load is more efficient than grid-connected loads and prevents the energy losses inherent in long-distance power transmission. The multi-story building could be an office building or a data storage center for multiple computers.
[0196] Example
[0197] The pipeline is approximately 150 miles long, and uses... Phosphate (50-70% of the suspension weight) is transported from high altitude to low altitude (below 2000 feet) at a rate of 0.06 w / w of iron ore. The pipeline is reconfigured to have intermittent outlets, allowing some of the aqueous suspension to flow through generators (one per outlet) to provide power, but returning the aqueous suspension to the pipeline. When power is needed or desired, the aqueous suspension flows through the outlets into the generator via 1-6 inch inner diameter pipes, which powers the load and / or charges and / or lithium-ion batteries.
[0198] There are wind farms along and near the pipeline, which turn propellers when the wind is strong enough. By using electricity generated from the flow of phosphate through the pipeline, the network of electricity generated by the pipeline and wind farms makes it possible to power the community with fewer batteries (compared to wind farms) or no batteries at all.
[0199] Example
[0200] Solar panels operate for approximately nine hours a day, and intermittently during the day due to interruptions such as storms and clouds. Demand is typically higher at night or during periods of disruption.
[0201] A 2,000,000-gallon container contains iron ore (85% by weight of the suspension) and (Containing 0.10% of the iron ore by weight), these can be added upon use or stored for future use. When electricity is needed or desired, the aqueous suspension flows under gravity through pipes with an inner diameter of 2-6 inches to a generator, which powers the equipment's load and, if not in use, charges the rare-earth batteries and / or lithium-ion batteries. During the operation of the solar generator (uninterrupted daytime), the solar energy returns the suspension to a container for reuse, after which the batteries are charged or the solar energy powers the facility's load.
[0202] Example
[0203] An electric vehicle is located miles from a power source in the desert, and its battery needs charging. A service truck is transporting a generator and a 500-gallon sealed container containing iron ore and... The truck contains an aqueous suspension of solid particles. An air compressor uses air or nitrogen to pressurize the top of the suspension, causing it to flow through a generator and return to the container. This pressurization is achieved by a battery powering the air compressor on the service truck. The electric vehicle's battery is fully charged, allowing it to continue driving to its destination. Additionally, the truck has a battery-powered flywheel sufficient to suppress head pressure fluctuations as fuel flows from the sealed fuel tank.
[0204] The dispatcher of the aforementioned service truck could have dispatched a second truck, just like the one already dispatched, but the second service truck's pressurization was powered by a gas generator that supplies electricity to the air compressor. Based on the remote location of the faulty electric vehicle, the dispatcher refused to select a third truck that would draw power from another grid (solar, natural gas).
[0205] The dispatcher is selecting an efficient system. Using compressed air generated from the turbine shaft to pump the aqueous suspension back to the top of the sealed container can improve the efficiency of container-based power generation. An air compressor is added to the turbine shaft to generate high-pressure air. This high-pressure air can be used to pressurize the container, thereby lifting the aqueous suspension. An air-driven positive displacement pump or centrifugal pump can provide additional lifting force to return the aqueous suspension to the container. The second truck is less environmentally friendly. The third truck relies on other sources of electricity.
