Technology Licensing Opportunity: Integrated Electrochemical System for Carbon Capture and Hydrogen Production

Description

Integrated Electrochemical System for Carbon Capture and Hydrogen Production A Modular, Energy-Efficient Solution for Reducing Atmospheric CO? The Challenge Current carbon capture technologies face significant hurdles in addressing both distributed CO? emissions and direct air capture (DAC). Current solutions are: Energy Intensive: Traditional methods rely on chemical solvents or solid adsorbents that demand high heat, steam, and electricity for regeneration. Infrastructure Heavy: Large absorption and desorption towers increase capital costs and system complexity. Inefficient DAC for Low CO? Concentrations: Capturing CO? from ambient air (400 ppm) remains technologically and economically challenging. These limitations impede scalability and economic viability, especially as global CO? emissions from distributed sources like transport remain a critical challenge. How It Works The proposed technology integrates a Carbonate-Composite Membrane Reactor (CCMR) with a Protonic Ceramic Electrolyzer (PCE) to enable efficient carbon capture, hydrogen production, and energy generation: Carbonate-Composite Membrane Reactor (CCMR): Captures CO? directly from ambient air while generating electricity and steam. Protonic Ceramic Electrolyzer (PCE): Produces renewable hydrogen using the steam and electricity generated by the CCMR. Thermal Balance: Couples the exothermic CCMR and endothermic PCE to create a thermally uniform and energy-efficient system. Closed Water Loop: Water produced in the CCMR is used for hydrogen production in the PCE, ensuring net-zero water consumption. This hybrid approach minimizes energy loss, reduces auxiliary power demand, and eliminates the need for traditional solvent regeneration processes. Key Advantages Energy Efficiency: Generates electricity and reuses heat within the system, lowering overall energy requirements. Net-Zero Water Consumption: Closed-loop operation ensures sustainable water usage. Scalability: Modular design supports deployment as distributed DAC units or centralized stations. Versatility: Operates at intermediate temperatures (~600�C), enabling integration with waste heat sources and a range of applications. Simplified Operation: Eliminates adsorption/desorption regeneration, reducing system complexity and costs. Sustainable Hydrogen Production: Uses renewable H? to drive CO? capture, achieving net-zero or negative emissions. Market Applications Carbon Management: Direct air capture for mitigating global CO? emissions. Industrial CO? Use: Captured CO? can be used for enhanced oil recovery, synthetic fuel production, and food/beverage carbonation. Distributed or Mobile Carbon Capture: Ideal for addressing emissions from transportation and other distributed sources. Point Source Applications: Captures CO? from concentrated sources, such as power plants or industrial facilities.
