Definition
Clean hydrogen production and fuel cell technologies for decarbonization
Technologies
PEM (Proton Exchange Membrane) electrolysis enables rapid response to variable renewable energy. Alkaline electrolysis provides proven, lower-cost hydrogen production. Solid oxide electrolysis operates at high temperature for improved efficiency. Hydrogen storage uses compression, liquefaction, or chemical carriers. Fuel cells convert hydrogen back to electricity for mobility and stationary power.
Applications
Green hydrogen replaces fossil-derived hydrogen in ammonia production and oil refining. Hydrogen fuel cells power heavy-duty trucks and buses. Green steel uses hydrogen instead of coal for iron ore reduction. Synthetic aviation fuel combines hydrogen with captured CO2.
Market and funding
Green hydrogen production from renewable energy via electrolysis represents one of the most capital-intensive but potentially transformative climate technologies. With 2 funders. Hydrogen is essential for decarbonizing steel, cement, shipping, and aviation.
