Summary:
The “Hydrogen Generation through Integrated Sustainable Electrolysis” (HYDROGENISE) project focuses on decentralized hydrogen (H2) production via proton exchange membrane electrolysis cells (PEMEC) to split water into hydrogen and oxygen (O2). The current 10 MW PEM electrolyzer operates with an energy requirement of approximately 50 kWh per kg of H2, producing 200 kg of H2 per hour. HYDROGENISE utilizes cost-effective, environmentally-friendly catalysts to electrolyze untreated water, achieving Faradaic efficiencies of 90%-100% for H2 production with instantaneous splitting reactions. The proprietary technology of this HYDROGENISE offers three significant benefits: Increased Efficiency: 50% higher water-splitting rates without pre-treatment compared to commercial catalysts. Enhanced Performance: 45% improved vehicle mileage and 52% longer drive-time in model hydrogen vehicle tests. Cost Reduction: Utilizes non-platinum group metals/metal oxide composites, reducing costs while maintaining performance and durability. This alpha-prototype HYDROGENISE technology has been tested using a model vehicle on a one-gallon scale and has the potential for scalability, representing a cutting-edge advancement in hydrogen production, contributing to materials science and clean energy technologies in alignment with the NSF I-Corps mission to address customer needs and commercialize innovative research. HYDROGENISE produces H2 for use in PEM fuel cells, generating electricity for vehicles, portable power supplies, and backup energy systems. Leading market players such as Hyundai Motor Group, General Motors, Ballard Power Systems, and Linde currently dominate the H2 production market. This initiative excels in efficient in-situ H2 generation from water, eliminating the need for costly preprocessing. By delivering cost savings of 35% ($2.6-$3.9 per kg) and boosting energy efficiency by 50% by 2028, HYDROGENISE is positioned as a cost-effective and sustainable solution in the clean energy market. The project simplifies the H2 production process, reducing costly preprocessing and lowering overall production costs. Key value propositions for hydrogen applications include reducing carbon footprints for environmentally conscious consumers and providing a reliable energy source for industries requiring uninterrupted power. Hydrogen's versatility in various applications makes it an attractive option for sectors looking to diversify their energy sources.
