(Invited) Efficient Generation of High Energy Density Fuel from Water

Abstract

Carbon-free energy generation is a necessity to meet rising global energy needs while minimizing environmental impact. Hydrogen has the potential to be a cost competitive and scalable solution to replace fossil fuels, and water electrolysis is an attractive concept for producing hydrogen with zero carbon footprint when integrated with a renewable energy source. Proton Energy Systems is a world leader in hydrogen generation from PEM electrolysis and has demonstrated the commercial viability of this technology in the industrial gas market, with pathways defined to reach targets in the energy markets. Recent catalyst research at Proton has demonstrated efficiency improvements while maintaining stability. Ongoing collaboration with 3M has also shown feasibility to reduce the catalyst loading by over an order of magnitude vs. current commercial loadings. This paper will discuss Proton's fueling efforts, particularly at high pressure, and advancements in efficiency which enable localized generation of hydrogen where it is needed.
