Description

[0001] APPARATUS TO CONVERT CARBON DIOXIDE INTO GLUCOSE USING ARTIFICIAL PHOTOSYNTHESIS

[0002] TECHNICAL FIELD

[0003]

[0001] The present invention relates to the field of renewable energy technologies and carbon capture systems. More particularly, the present disclosure pertains to an apparatus for converting atmospheric carbon dioxide (CO2) into glucose (CeHnOe) using artificial photosynthesis.

[0004] BACKGROUND

[0005]

[0002] Changing environmental patterns and increasing levels of carbon dioxide in the atmosphere are among biggest challenges faced by people nowadays. Fossil fuel-based power plants, which are key contributors to global electricity production, are also a major source of carbon dioxide emissions. This has led to significant consequences such as glacier melt, biodiversity loss, extreme heatwaves, and disruptions to ecosystems. These effects are not limited to environmental damage but also impact economies and human societies around the world.

[0006]

[0003] To address this, two main approaches are being explored. First is carbon capture and utilization (CCU), which includes capturing carbon dioxide from the atmosphere and using it to produce valuable products. Second is use of renewable energy resources, such as solar, wind, and hydropower. These renewable sources have the potential to provide up to 90% of the world’s power generation by 2050, provided global initiatives and government plans are implemented effectively.

[0007]

[0004] However, renewable energy resources come with their own set of challenges. Their intermittent nature and location dependency make them unstable, requiring alternative storage solutions to ensure a steady supply of energy. Existing electricity storage methods, such as batteries, have limitations, including difficulty in storing large amounts of energy for long durations, heavy weight, and space constraints, particularly in isolated applications. Furthermore, while renewable energy is environmentally friendly compared to fossil fuels, the processes involved in producing renewable electricity still result in emissions, including greenhouse gases.

[0008]

[0005] In recent years, power-to-X technology has emerged as a promising solution. This technology involves converting renewable electricity into various chemical products, such as hydrogen or methanol, which can serve as alternative energy carriers or raw materials. Power-to-X not only helps mitigate carbon emissions but also addresses the storage challenges of renewable energy by converting surplus electricity into storable forms. Despite its potential, the current applications of power-to-X are primarily focused on industrial processes.

[0009]

[0006] Therefore, there is a need for a solution that addresses the issue of greenhouse gas emissions by using artificial photosynthesis to produce a biocompatible and sustainable product.

[0011]

[0007] An object of the present disclosure is to provide a solution that integrates carbon capture with utilization by employing artificial photosynthesis to convert captured CO2 into glucose.

[0012]

[0008] Another object of the present disclosure is to provide a solution that mitigates greenhouse gas emissions and creates value-added products, transforming carbon from a waste product into a resource.

[0013]

[0009] Another object of the present disclosure is to provide dual functionality for carbon fixation and oxygen production, ensuring effective use of CO2 while also generating green oxygen as a by-product, contributing to a cleaner and healthier environment.

[0014]

[0010] Another object of the present disclosure is to provide an apparatus powered by renewable energy, specifically wind energy, ensuring that CO2 capture and utilization processes are sustainable, this eliminates reliance on fossil fuels or grid electricity for operations of the apparatus.

[0015] [OH] Another object of the present disclosure is to provide a solution scalable design with sensitivity analysis, offering insights into optimizing wind energy utilization for glucose production, and this adaptability allows the system to perform effectively under various environmental conditions and scales of operation.

[0028] DETAILED DESCRIPTION

[0029]

[0023] The following is a detailed description of embodiments of the disclosure depicted in the accompanying drawings. The embodiments are in such detail as to clearly communicate the disclosure. However, the amount of detail offered is not intended to limit the anticipated variations of embodiments; on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the present disclosures as defined by the appended claims.

[0030]

[0024] Embodiments explained herein relate to the field of renewable energy technologies and carbon capture systems. More particularly, the present disclosure pertains to an apparatus for converting atmospheric carbon dioxide (CO2) into glucose (CeHnOe) using artificial photosynthesis.

[0031]

[0025] An embodiment of the present disclosure relates to an apparatus for converting carbon dioxide into glucose using artificial photosynthesis. The apparatus includes several integrated components working together seamlessly. A carbon capture unit is configured to capture atmospheric carbon dioxide and operates with an amine-based absorber, which selectively captures the carbon dioxide from the atmosphere, ensuring an efficient and effective process. The captured carbon dioxide is further processed by an absorber and separator unit, which desorbs and concentrates the carbon dioxide to release it in its pure form. The absorber and separator unit operates under predefined temperature and pressure conditions to ensureoptimal separation and functionality. In addition, water is received by an electrobath, which processes the water through electrolysis to produce pure water for a synthesis process.

[0032]

[0026] In addition, a reactor is utilized for receiving pure carbon dioxide from the absorber and separator unit and pure water from the electrobath to synthesize glucose through artificial photosynthesis. This process is achieved under controlled conditions where the reactor simulates photosynthetic environments using preset light wavelengths and catalysts to facilitate the reaction, ensuring high efficiency and output. Furthermore, the reactor is configured to manage unreacted carbon dioxide effectively by redirecting it back to the carbon capture unit, minimizing wastage and ensuring the maximum utilization of resources.

[0033]

[0027] Referring to FIG. 1 , an exemplary diagram of proposed apparatus for converting atmospheric carbon dioxide into glucose using artificial photosynthesis is disclosed. The apparatus (100) includes a carbon capture unit (102) configured to capture atmospheric carbon dioxide (CO2). The carbon capture unit (102) utilizes an amine-based absorber to selectively capture the atmospheric carbon dioxide (CO2). The amine-based absorber is a chemical system capable of selectively capturing atmospheric carbon dioxide. This ensures efficient separation of CO2 from other atmospheric gases, making it available for further processing within the apparatus (100).

[0034]

[0028] In an embodiment, the apparatus (100) includes an absorber and separator unit (104-1, 104-2) (interchangeably referred to as separator and concentrator unit (104-1, 104-2), herein) configured to refine the carbon dioxide captured by the carbon capture unit (102). After the carbon capture unit (102) extracts CO2 from the atmosphere using the amine-based absorber, the captured CO2 is directed to the absorber and separator unit (104-1, 104-2). This absorber and separator unit (104-1, 104-2) is configured to desorb the carbon dioxide, i.e. releases CO2 from the amine-based absorber, and further concentrates it to ensure a higher purity. The absorber and separator unit (104-1, 104-2) achieves this by operating under predefined temperature and pressure conditions, which are carefully optimized to enhance efficiency of the desorption and concentration processes. The result is the release of pure carbon dioxide, which is utilized in subsequent stages of the apparatus for glucose synthesis.

[0035]

[0029] In an embodiment, the apparatus ( 100) includes an electrobath ( 106) configured to receive water (H2O) and process the received water to provide pure water (H2O) through an electrolysis process. The electrobath (106) receives input water, which might contain impurities or contaminants, and then subjects it to electrolysis uses electrical energy to split water molecules into their basic components, such as hydrogen (H2) and oxygen (O2). For instance,use of electrolysis guarantees a high level of water purity, which is essential for maintaining efficiency and effectiveness of the apparatus.

[0036]

[0030] In an embodiment, the apparatus (100) includes a glucose reactor (108) (interchangeably referred to as reactor (108), hereinafter) for synthesizing glucose (CeHnOe) by combining pure carbon dioxide (CO2), received from the absorber and separator unit (104-1, 104-2), with pure water (H2O), supplied by the electrobath (106). The reactor operates under controlled conditions and utilises principles of artificial photosynthesis to achieve this synthesis. To replicate the photosynthetic process, the reactor (108) utilizes preset light wavelengths and catalysts. These components work in harmony to facilitate chemical reactions required for conversion of CO2 and H2O into glucose. By mimicking natural photosynthesis, the reactor ensures efficient and sustainable production of glucose.

[0037]

[0031] In addition, the reactor (108) is configured to simulate two distinct phases of photosynthesis a light phase and a dark phase. During the light phase the reactor (108) uses preset light wavelengths to activate catalytic agents. These agents drive the initial chemical reactions, converting CO2 and H2O into intermediate compounds. The activation of these catalytic agents initiates and sustains the photosynthetic process.

[0038]

[0032] In the subsequent dark phase, the intermediate compounds formed during the light phase undergo further transformation. Through internal chemical reactions under controlled conditions, these intermediate compounds are converted into glucose (CeHnOe). This dark phase does not require light but relies heavily on efficiency of light phase reactions and the controlled environment within the reactor (108).

[0039]

[0033] Further, the reactor (108) is provided to replicate complex biochemical processes of natural photosynthesis, offering an innovative approach to synthesize glucose while reducing atmospheric CO2 levels. Its ability to operate in the controlled, scalable manner makes this a vital component of the apparatus (100).

[0040]

[0034] In an embodiment, the apparatus (100) ensures efficient utilization of carbon dioxide (CO2) and minimize waste. The absorber and separator unit (104-1, 104-2) is configured to handle any unreacted CO2 that remains after the reaction process in the reactor (108). This unreacted CO2 is collected and redirected back into the carbon capture unit (102) for reuse. Initially, the unreacted CO2 from the reactor (108) is routed to the absorber and separator unit (104-1, 104-2). The absorber and separator unit (104-1, 104-2) processes this CO2 to desorb and concentrate it, ensuring that it is pure and ready for another cycle of reaction. Once processed, the absorber and separator unit (104-1, 104-2) directs this CO2 back to the reactor (108), allowing it to participate in further glucose synthesis. By continuously recyclingand reusing CO2, the apparatus (100) optimizes the glucose production process while reducing its environmental footprint.

[0041]

[0035] In an exemplary embodiment, glucose synthesized by the apparatus through artificial photosynthesis holds significant potential for applications in the chemical commerce sector (122). As a versatile and renewable raw material, glucose can serve as a precursor for various biochemical and industrial processes. This can be utilized in the production of biobased chemicals, such as bioethanol, bioplastics, and organic acids, which are essential in creating sustainable alternatives to fossil fuel-derived products. Additionally, glucose can play a critical role in fermentation processes for producing biofuels and other high-value products like amino acids, vitamins, and pharmaceutical compounds. Its biocompatibility and renewable nature make it an attractive feedstock for industries seeking to align with environmentally friendly practices and reduce their carbon footprint. By utilizing glucose in chemical commerce, industries can promote a circular economy while contributing to the reduction of greenhouse gas emissions and fostering sustainable development.

[0042]

[0036] In an embodiment, the apparatus (100) operates sustainably by utilizing a renewable energy source (120) to power all its essential components, including the carbon capture unit (102), the absorber and separator unit (104-1, 104-2), the electrobath (106), and the reactor (108). This ensures that the apparatus (100) not only captures and reduces atmospheric carbon dioxide levels but also minimizes its environmental impact by avoiding reliance on fossil fuels or conventional grid electricity. The renewable energy source (120) can be any sustainable option, such as a wind power plant, which generates electricity by harnessing wind energy.

[0043]

[0037] In an exemplary embodiment, the electricity produced from this renewable energy source (120) drives the processes within the apparatus (100), such as carbon capture in the carbon capture unit (102), where CO2 is selectively absorbed from the atmosphere and the desorption and concentration of CO2 in the absorber and separator unit (104-1, 104-2) under controlled temperature and pressure conditions. Additionally, the electrobath (106) utilizes this power to perform water electrolysis, generating pure water for further processing. The reactor (108) also relies on renewable energy to facilitate artificial photosynthesis, combining CO2 and H2O under controlled conditions to synthesize glucose. By utilizing renewable energy like wind power, the apparatus (100) achieves an environmentally friendly and carbon-neutral operation, making it an effective tool for addressing climate change. This integration not only supports global sustainability goals but also enhances the efficiency and cost-effectiveness of the apparatus (100) for long-term use.

[0038] In an exemplary implementation as shown in FIG. 1, during carbon capture (CC) approach, atmospheric CO2 is collected through direct air capture unit (102) (i.e. carbon capture unit) using amine-based absorber. The CO2 reacts with the amine-based material. The absorbed CO2 is further sent to the stripper & separator (104) (i.e. absorber and separator unit (104-1, 104-2)) for desorption and concentration to get pure CO2. The chemical reactions involved are as follows:

[0044] CO2 Absorber:

[0045]

[0046] CO2 Separator: CH3NO2 + H2O+CO2 + H2O + C2H7NO (2)

[0047]

[0039] In addition, during power to gas (P2G) approach, firstly, for collecting pure H2O or sometimes pure H2, water electrolyzer (106) is used. Here, alkaline electrolyzer operation takes place. During this process, water undergoes splitting and oxidation reactions to produce hydrogen gas and oxygen gas. The reactions are as follows:

[0048] Water Splitting:

[0049]

[0050] Oxidation: 2OH’ H2O + I / 2O2 + 2e (4)

[0051]

[0040] Subsequently, working of glucose reactor (GR) (108) (i.e. reactor) takes place under P2G approach. The pure CO2 from CC-Approach and the pure H2O from the electrobath (106) are collected for synthesizing glucose on the GR (108). The proposed apparatus (100) is very unique due to functional characteristics of glucose reactor (108). This glucose reactor (108) is utilizing nature-inspired concept, photosynthesis, to produce glucose from renewable power plant-derived CO2 and renewable power. The general chemical equation used by glucose reactor (108) is:

[0052]

[0053]

[0041] This artificial photosynthesis concept (AP) has two different phases of its lifespan like natural photosynthesis (NP): light dependent reaction or light phase and light independent reaction or dark phase. Being an endothermic process, photosynthesis requires energy input. During the light phase, a wind-powered 9W LED grow light is used as the light source, simulating oxygenic photosynthesis. The reaction begins at a temperature range of 25-35°C and 1 bar pressure. The input for the light phase includes water from the electrobath (106) and light energy. The chemical equation for the light phase is:

[0054]

[0055] I 8C10H16N5O13P3 (6)

[0056]

[0042] In the dark phase, the energy generated from the light phase and CC-derived CO2 is entered. This dark phase does not require direct light but is dependent on the outputs ofthe light phase. The dark phase involves carbon fixation, reduction, and regeneration processes to produce glucose. The chemical equation for the dark phase is:

[0057]

[0058] I2C21H29N7O17P3 (7)

[0059]

[0043] Referring to FIG. 2, an exemplary functional view (200) of a process of artificial photosynthesis, using the proposed glucose reactor (108) that converts carbon dioxide into glucose using artificial photosynthesis. The process includes two phases a light phase and a dark phase . In a light phase chamber (202), water (H2O) from the electrobath (106) enters, and light energy (photons) is utilized to split water molecules through a simulated photosynthesis process using a reaction, through equation (8):

[0060]

[0061]

[0044] This reaction generates oxygen (O2), protons (H+), and energy-rich molecules essential for glucose synthesis, which are directed to a separator (206). The oxygen produced in the light phase chamber (202) is separated and collected by the separator (206) using equation (9):

[0062] I2C21H30N7O17P3 +H++ I8C10H16N5O13P3 (9)

[0063]

[0045] The remaining components (C21H30N7O17P3 + 2H++ C10H16N5O13P3) of the equation (8) are directed to a dark phase chamber (204).

[0064]

[0046] The dark phase chamber (204) receives pure carbon dioxide (CO2) from the carbon capture unit (102), and using the components (C21H30N7O17P3 +2H++ C10H16N5O13P3) from the light phase chamber (202), undergoes a chemical reaction to produce glucose (CeHnOe) through equation (10):

[0065]

[0066] C21H29N7O17P3 (10)

[0067]

[0047] Further, outcome of the dark phase chamber (204) is directed to a separator and concentrator (208), where glucose (CeHnOe) is separated and concentrated. In addition, unreacted components, such as residual CO2 or water, are recycled back into the process to ensure efficiency and sustainability. The proposed apparatus (100) efficiently mimics natural photosynthesis, combining the light-dependent and light-independent (dark) phases to convert carbon dioxide and water into glucose while releasing oxygen as a byproduct.

[0068]

[0048] In an exemplary implementation, the above process replicates artificial photosynthesis to convert water and carbon dioxide into glucose. In the light phase (202), water is split using light energy, producing oxygen, protons, and energy-rich molecules. Theseparator (206) removes oxygen and transmits the remaining components to the dark phase (204), where CO2 reacts to form glucose. The separator and concentrator (208) then extract and purify the glucose while recycling unreacted components for efficiency.

[0069]

[0049] Referring to FIG. 3, an exemplary flow diagram (300) to illustrate working of proposed apparatus (100) is disclosed. At step (302), carbon dioxide (CO2) is captured directly from atmosphere by the carbon capture unit (102), and at step (304), electricity is received from renewable electricity sources such as wind turbines ensuring that the process is sustainable and environmentally friendly.

[0070]

[0050] At step (306), high-purity hydrogen (H2) and water (H2O) are received from the electrolyzer (106), which uses renewable electricity to split water molecules, producing pure water necessary for glucose synthesis. In addition, light energy, specifically photons, is captured and directed to the light phase chamber, at block (308). This step mimics natural photosynthesis by providing energy for splitting water molecules into hydrogen (H2) and oxygen (O2) and facilitating further reactions in the light phase.

[0071]

[0051] At step (310), the light phase chamber / reformer, equipped with a nafion-based proton exchange membrane (PEM), processes the carbon dioxide, hydrogen and water along with light energy to drive reactions of the light phase of artificial photosynthesis. The result is a mixture of intermediate compounds necessary for glucose production.

[0072]

[0052] At step (312), the absorber and separator unit (104-1, 104-2) isolate unreacted components and byproducts generated during the light phase. This redirects reusable materials back into the apparatus (100) while ensuring that only the required intermediates are passed to the dark phase reformer.

[0073]

[0053] At step (314), the dark phase chamber / reformer, which employs a Cu / Zn catalyst, combines the intermediates received from the light phase with CO2 to synthesize glucose (CeHnOe). The reactions occur in controlled conditions that simulate the Calvin cycle, completing the glucose production process. Any unreacted components or byproducts are recycled back into the step (310) for further processing, ensuring maximum efficiency and minimal waste.

[0074]

[0054] At step (316), a separator (208) collects and concentrates the synthesized glucose from the dark phase chamber (204).

[0075]

[0055] Further, at step (318), pure glucose (CeHnOe) is extracted as final product. This glucose can be utilized in various applications, such as biofuels, bioplastics, or as a raw material in food and pharmaceutical industries. Also, the produced glucose can be used in glucose fuel cells for producing electricity.

[0056] Thus, the present disclosure provides the apparatus for addressing challenges of atmospheric carbon dioxide reduction and glucose production, combining advanced engineering with sustainable energy principles to create a versatile and environmentally friendly technology. This integrates carbon capture, water processing, and artificial photosynthesis in a cohesive design, offering a practical approach to mitigate climate change and support renewable energy initiatives.
