Description

[0001] With the acceleration of the global energy transition, the intermittency and spatiotemporal mismatch of new energy sources such as photovoltaic power generation are becoming increasingly prominent. The widespread waste of electricity generated during the day due to high photovoltaic output is a serious problem. Meanwhile, the disposal of solid waste such as municipal solid waste, septic tank waste, and sewage sludge still relies on landfill and incineration, which not only occupies scarce land resources but also generates large amounts of pollutants such as carbon dioxide and dioxins. Existing technologies cannot simultaneously solve the two core problems of renewable energy waste and solid waste pollution. This patent proposes a global energy complementarity and solid waste co-processing system based on day-night time difference satellite microwaves. Building upon existing transnational energy complementarity scheduling systems based on day-night time differences, this system expands the application scenarios of microwave energy, converting surplus photovoltaic power into microwave signals, which are then transmitted transnationally via a low-orbit relay satellite constellation. The excess microwave energy is directly used for the closed, anaerobic, and pollution-free treatment of municipal solid waste, septic tank waste, and sewage sludge, eliminating the need for incineration, landfill, and manual sorting. The system retains the original five core modules of energy dispatch and adds a microwave solid waste pyrolysis treatment module and a product separation and recycling module. It not only achieves an efficient solution to the spatiotemporal mismatch of global new energy sources, but also completes the full resource utilization of solid waste. It has the advantages of zero fossil energy consumption, fully automatic operation, no secondary pollution, and synergistic solution to dual problems, which greatly improves the utilization rate of new energy sources, completely breaks through the bottleneck of traditional solid waste disposal, and provides an integrated and innovative solution for global low-carbon energy development and ecological environmental protection.

[0003] 1 Introduction

[0004] 1.1 The Dual Status Quo and Challenges of Global Energy and Solid Waste Disposal

[0005] As the global energy structure transitions towards a low-carbon model, the installed capacity of new energy sources such as photovoltaics and wind power continues to climb. However, the intermittent and fluctuating nature of their power generation makes it difficult to solve the problem of temporal and spatial mismatch: in areas with abundant sunshine during the day, photovoltaic power generation far exceeds the local grid's absorption capacity, resulting in a large amount of wasted electricity, while in areas with power shortages at night, thermal power is needed to supplement the power supply, further exacerbating carbon emissions and environmental pollution. At the same time, the global urbanization process is accelerating, leading to a surge in the production of solid waste such as urban domestic waste, sewage from septic tanks, sludge from sewage treatment plants, and sludge bricks made from fecal residue. Existing disposal methods have fatal flaws: landfills occupy scarce land resources, leachate pollutes groundwater, and releases the potent greenhouse gas methane; while waste incineration and sludge incineration can generate a small amount of electricity, they produce pollutants such as carbon dioxide, dioxins, and dust, harming the ecology and human health, and failing to achieve resource recycling. Currently, there is no technology globally that can simultaneously solve the two core pain points of renewable energy wastage and solid waste landfill and incineration pollution. The two problems are handled independently, resulting in low efficiency and high costs, urgently requiring an integrated and collaborative solution.

[0006] 1.2 Limitations of Existing Technology

[0007] Existing energy dispatch technologies primarily focus on regional power allocation and transoceanic wired power transmission. The former cannot address the global day-night energy mismatch, while the latter suffers from high infrastructure costs, significant transmission losses, and difficulty in overcoming ocean barriers. Wireless microwave power transmission technology is solely used for power transmission, failing to fully utilize surplus microwave energy for environmental applications, resulting in the indirect waste of a large amount of microwave energy converted from abandoned power. Existing solid waste treatment technologies, whether landfill, incineration, manual recycling, or biological treatment, all suffer from pollution, land occupation, high costs, and low efficiency, and all rely on grid power, further increasing energy consumption and carbon emissions. Some microwave solid waste treatment technologies only utilize local grid power, failing to incorporate renewable energy, resulting in poor economic feasibility and hindering large-scale promotion. Furthermore, existing technologies have not integrated global day-night satellite microwave energy dispatch with the harmless treatment of solid waste to form an energy-environmental closed-loop system, leaving a significant technological gap.

[0008] 1.3 Research Objectives and Significance

[0009] This patent, an improvement and extension of the applicant's earlier patent application, "A Satellite Microwave Transnational Energy Complementary Dispatch System Based on Day and Night Time Difference," aims to overcome the limitations of existing single-technology approaches and construct an integrated collaborative system for energy complementarity and solid waste treatment. It converts previously wasted photovoltaic power into microwave energy, achieving both transnational energy dispatch and the harmless treatment of solid waste using surplus microwave energy—a win-win situation. This system completely eliminates the landfill and incineration methods for solid waste, eliminating the need for manual sorting and recycling. Utilizing microwave-sealed anaerobic pyrolysis technology, it achieves the full resource conversion of garbage, excrement, and sludge, while significantly reducing photovoltaic power curtailment and the use of thermal power. Its research results not only improve the global clean energy dispatch system but also solve the persistent problem of solid waste pollution in the process of urbanization. It has significant strategic and practical value for promoting the achievement of global carbon neutrality goals, building waste-free cities, and realizing the coordinated and sustainable development of energy and ecology.

[0010] 2. Literature Review

[0011] 2.1 Current Status of Global Energy Dispatch Theories and Technologies

[0012] The core theory of energy dispatch revolves around the balance of power supply and demand and the optimal allocation of resources. Traditional dispatching technology mainly relies on high-voltage wired power transmission over land, which is suitable for short-distance regional power grid interconnection but cannot achieve transoceanic and intercontinental energy transmission. In recent years, wireless microwave power transmission technology has gradually developed, focusing on power transmission in a single region. The transnational energy dispatching technology that combines global day and night time differences has only been proposed by the applicant in a prior patent. It has achieved efficient transmission of surplus photovoltaic power during the day to power-deficient areas at night, solving the problem of spatiotemporal mismatch of new energy sources. However, this technology is only applied to power supply and does not diversify the utilization of surplus microwave energy, so there is still room for improvement in energy utilization efficiency.

[0013] 2.2 Research Progress in Solid Waste Treatment Technology

[0014] Existing solid waste treatment technologies are mainly divided into five categories: landfill, incineration, manual recycling, biological treatment, and physicochemical treatment. Landfill technology requires large land areas and causes heavy pollution, and its use has been restricted in most cities; incineration technology causes secondary pollution and serious resource waste; manual recycling relies on manual sorting, which is inefficient, costly, and environmentally unfriendly; biological treatment (such as insect conversion and anaerobic fermentation) can only treat organic solid waste, has a narrow scope of application, and a long treatment cycle; although microwave pyrolysis technology can achieve the harmless treatment of solid waste, existing technologies all rely on grid power, resulting in high energy costs, and lack economic feasibility due to the lack of integration with renewable energy curtailment. Furthermore, it does not cover special solid wastes such as septic tank feces and sewage sludge, limiting its application scenarios.

[0015] 2.3 Gap in Satellite Microwave Technology Combined with Solid Waste Treatment

[0016] A search revealed that no existing technology combines a satellite microwave transnational energy dispatch system based on day-night time differences with the harmless treatment of solid waste. No integrated system has been established that utilizes microwave energy converted from photovoltaic power curtailment to simultaneously achieve transnational energy complementarity and solid waste pyrolysis disposal. The applicant's prior patent only protects the satellite microwave transnational energy complementarity dispatch architecture. This patent, by adding a solid waste co-processing module on top of this, represents a completely new combination innovation, filling a gap in energy and environmental protection synergy technology and possessing significant inventiveness and novelty.

[0017] 3 System Overall Principle

[0018] 3.1 Core Fundamental Principles

[0019] Based on the global day-night cycle caused by the Earth's rotation, photovoltaic power plants in areas with abundant sunshine during the day generate a large amount of surplus electricity, exceeding the local power grid's absorption capacity and resulting in wasted electricity. This wasted electricity is collected by a renewable energy waste collection module and regulated and rectified into DC power. The DC power is then converted into a high-frequency directional microwave signal by a microwave conversion and transmission module. This signal is received, amplified, and relayed by a low-orbit relay satellite cluster and transmitted to areas with power shortages at night. The DC power is then converted into AC power by a ground microwave receiving and rectification module and connected to the local power grid, achieving cross-border energy complementarity. The intelligent time-difference scheduling and control module matches supply and demand in real time and dynamically adjusts the transmission path and power, ensuring fully automated operation.

[0020] 3.2 New Principle of Co-treatment of Solid Waste

[0021] Based on the aforementioned energy dispatch, the surplus microwave energy generated during transmission and local consumption is directly introduced into the microwave solid waste pyrolysis module for closed-loop anaerobic microwave pyrolysis of solid waste such as domestic waste, septic tank waste, sewage truck sludge, sewage treatment plant sludge, and fecal bricks. Utilizing the high-frequency vibration characteristics of microwaves, the water molecules inside the solid waste are rapidly heated. In an anaerobic environment, open flame combustion is avoided, and pollutants such as dioxins and carbon dioxide are not produced. At the same time, the molecular chains of the solid waste are broken, automatically separating into four products: condensate, combustible gas, fuel oil, and sterile char residue. This achieves full resource utilization, with no landfill, no incineration, and no manual sorting throughout the entire process, completely solving the problem of solid waste pollution.

[0022] 3.3 System Synergy Advantages

[0023] 1. Simultaneous resolution of two major social problems: It simultaneously absorbs waste solar power, improving energy efficiency, and harmlessly treats solid waste, achieving resource recycling and addressing two major social pain points; 2. Zero additional energy consumption: Solid waste treatment utilizes the originally wasted waste electricity converted into microwave energy, eliminating the need for mains power and resulting in extremely low treatment costs; 3. No secondary pollution: Closed-loop anaerobic pyrolysis produces no waste gas, wastewater, or waste residue emissions, and all products are recyclable; 4. Full-scenario coverage: It can treat various types of domestic waste, excrement, and sludge without requiring sorting, making it suitable for all urban solid waste disposal scenarios; 5. Consistent and conflict-free: Based on the applicant's prior technological improvements, the technology system is complete, and the scope of protection is comprehensive.

[0024] 4 System Composition

[0025] Based on the five core modules of the applicant's prior patent—new energy curtailment acquisition module, microwave conversion and transmission module, low-orbit relay satellite cluster, ground microwave receiving and rectification module, and intelligent time difference scheduling and control module—this system adds a microwave solid waste pyrolysis treatment module and a product separation and recycling module, forming a complete integrated energy-environmental protection system.

[0026] 4.1 The original five core modules

[0027] Deployed in regions rich in global photovoltaic resources, it collects surplus photovoltaic power that cannot be absorbed by the local power grid in real time, completes multi-stage voltage regulation and rectification through voltage adaptation circuits, and outputs stable DC power to provide energy input for microwave conversion and transmission modules, thus eliminating the waste of power.

[0028] 4.1.2 Microwave Conversion and Transmission Module

[0029] It efficiently converts DC power into high-frequency directional microwave signals of 2.45GHz or 5.8GHz, uses a phased array transmitting antenna, and precisely controls the transmission angle to ensure directional transmission of microwave signals to the low-Earth orbit relay satellite constellation. The conversion efficiency is over 90%, and it is equipped with an adaptive power control algorithm to dynamically adjust the transmission power according to energy demand and solid waste treatment volume.

[0030] 4.1.3 Low Earth Orbit Relay Satellite Constellation

[0031] Composed of multiple distributed constellation satellites at an orbital altitude of 500-2000 kilometers, it achieves global coverage through inter-satellite links. It receives ground microwave signals, amplifies and calibrates them, and then relays them to ground receivers in areas with power shortages at night. At the same time, it can also directionally forward some microwave energy to local and global solid waste treatment sites, achieving precise energy distribution.

[0032] 4.1.4 Ground Microwave Receiver and Rectifier Module

[0033] Deployed in areas with power shortages at night and at solid waste treatment sites, the microwave signal is converted into industrial frequency AC power and connected to the power grid in areas with power shortages; the solid waste treatment sites directly transmit the received microwave energy to the pyrolysis processing module without secondary power conversion, and the microwave-DC / energy conversion efficiency is not less than 85%.

[0034] 4.1.5 Intelligent Time Difference Scheduling Control Module

[0035] Built-in global day-night time difference database, GIS geographic information system, and WAMS wide-area monitoring system, it monitors global photovoltaic curtailment, regional power grid load, and solid waste generation in real time, and dynamically allocates microwave energy: prioritizing cross-border power supply, and using all surplus energy for solid waste treatment, automatically adjusting the cracking power and processing speed to achieve fully automated coordinated operation of energy dispatch and solid waste treatment.

[0036] 4.2 Two new core modules added

[0037] 4.2.1 Microwave Solid Waste Pyrolysis Treatment Module

[0038] It is a fully enclosed metal reaction chamber with an anaerobic environment creation function and a built-in microwave radiation unit that directly receives microwave energy transmitted from the ground. It can accept various solid wastes such as unsorted domestic waste, septic tank sewage, sewage sludge, and fecal bricks. No pretreatment is required. Microwave radiation causes the water molecules inside the solid waste to vibrate and heat up violently, completing the pyrolysis in an anaerobic environment of 300-500℃. The entire process is flameless, smokeless, and odorless, with high processing efficiency, short processing time per chamber, and a solid waste volume reduction rate of 80%-90%.

[0039] 4.2.2 Product Separation and Recovery Module

[0040] Seamlessly integrated with microwave solid waste pyrolysis treatment modules, it achieves automatic stratification and separation by utilizing the physical properties of different products, eliminating the need for additional sorting equipment.

[0041] 1. Condensate Recovery Unit: Collects water vapor generated from pyrolysis, cools it to form qualified clean water, which can be directly discharged into natural water bodies or reused in cities; 2. Combustible Gas Collection Unit: Collects methane, hydrogen and other combustible gases generated from the pyrolysis of feces and organic waste, which can be used for auxiliary power generation or city gas supply; 3. Fuel Oil Recovery Unit: Collects fuel oil generated from the pyrolysis of plastic and fibrous solid waste, which can be used as chemical raw materials or fuel; 4. Carbon Slag Recovery Unit: Collects inorganic carbon slag after pyrolysis, which is sterile, odorless and non-toxic, and can be used for brick making, building material production and landscaping soil improvement.

[0042] 5 System Workflow

[0043] 1. Waste Power Collection: During the day, in areas rich in photovoltaic power, the renewable energy waste power collection module collects surplus photovoltaic power from the grid in real time and completes voltage stabilization and rectification; 2. Microwave Conversion and Transmission: The microwave conversion and transmission module converts DC power into directional microwave signals and transmits them to a low-orbit relay satellite constellation; 3. Energy Dispatch and Allocation: The intelligent time-difference dispatch and control module divides microwave energy into two parts through the satellite constellation based on global day-night conditions, grid load, and solid waste treatment needs: one part is transmitted to areas with power shortages at night and converted into electricity for grid connection by the receiving and rectification module; the other part is directly transmitted to solid waste treatment sites in various cities; 4. Solid Waste Pyrolysis Treatment: Microwave energy is introduced into a sealed pyrolysis chamber for anaerobic microwave pyrolysis of various solid wastes, with the entire process being closed and pollution-free; 5. Product Separation and Utilization: Pyrolysis products are automatically separated by a separation and recovery module, condensate is discharged / reused in compliance with standards, combustible gases and fuel oil are collected and reused, and charcoal slag is processed into building materials / garden soil; 6. Dynamic control: The intelligent module monitors photovoltaic power generation, abandoned power, and solid waste treatment progress in real time, and dynamically adjusts microwave energy distribution. The stronger the sunlight during the day and the more abandoned power, the stronger the solid waste treatment capacity. If there is no abandoned power at night, the treatment is suspended and waits for the next day to cycle.

[0044] 6. System Technical Challenges and Solutions

[0045] 6.1 Microwave energy transmission loss problem

[0046] Following the prior patented solution strategy, atmospheric window frequencies (2.45GHz / 5.8GHz) are selected to reduce atmospheric absorption, high-gain phased array antennas are used to improve beam focusing, and satellite on-board signal amplification technology is used to compensate for transmission loss, ensuring that the solid waste treatment module receives sufficient energy.

[0047] 6.2 Issues related to the uniformity of solid waste pyrolysis

[0048] Distributed microwave radiation units are designed inside the sealed pyrolysis chamber to ensure that solid waste receives microwave energy from all directions, avoiding incomplete local pyrolysis. At the same time, an automatic material turning mechanism is equipped to work with microwave radiation to achieve full and uniform pyrolysis of solid waste.

[0049] 6.3 Satellite orbit and system cooperative stability issues

[0050] Continuing with the prior patented distributed satellite constellation planning and collision avoidance technology, the system adds a linkage redundancy design between the solid waste treatment module and the energy dispatch module, equips key equipment with backups, and establishes a real-time fault monitoring and early warning mechanism to ensure the synchronous and stable operation of energy transmission and solid waste treatment.

[0051] 7 System Application Case Analysis

[0052] 7.1 Case Background

[0053] The study selected a photovoltaic-rich region in East Asia (during the day, where photovoltaic power curtailment is severe) and western North America (at night, where power is scarce) as energy complementarity areas. At the same time, a city in East Asia was selected as a solid waste treatment scenario. This city generates a large amount of domestic waste, sewage from septic tanks in residential areas, and sludge from sewage treatment plants every day. Traditional disposal methods mainly involve incineration and landfill, which cause serious pollution.

[0054] 7.2 Application Process

[0055] Surplus solar power generated during the day in East Asia is collected and converted into microwave signals. A satellite constellation then transmits a portion of this microwave energy to western North America to meet local nighttime electricity needs. The surplus microwave energy is then transported to the city's solid waste treatment plant, where a closed pyrolysis chamber processes various types of urban solid waste. Anaerobic pyrolysis separates condensate, combustible gases, fuel oil, and carbon residue, all of which are then utilized as resources. The entire process is automatically controlled by an intelligent scheduling module, requiring no human intervention, and simultaneously achieving three major goals: waste power utilization, cross-border power supply, and harmless treatment of solid waste.

[0056] 7.3 Application Effects

[0057] 1. Energy aspect: The photovoltaic curtailment rate is reduced from over 30% to below 5%, energy utilization rate is increased by over 60%, the use of thermal power in areas with nighttime power shortages is reduced, and carbon emissions are significantly reduced; 2. Environmental aspect: It completely replaces solid waste landfill and incineration, with no land occupation and no pollutant emissions, and the resource utilization rate of solid waste reaches 100%; 3. Economic aspect: Solid waste treatment does not require the consumption of grid electricity, the cost is extremely low, and the recycling and reuse of products generates additional economic benefits. The overall system cost-effectiveness far exceeds that of existing technologies.
