Caltech’s Nate Lewis on Converting Scalable Sunlight-to-Fuel with Green Hydrogen

Nate Lewis

Nate Lewis elaborates on what his research team discovered about converting electricity into fuel and green hydrogen’s role as a critical enabling technology for decarbonizing transportation fuels and scaling long-term grid energy storage

Nate Lewis Leads US Energy Innovation Hub at Caltech


Nate Lewis is the George L. Argyros Professor of Chemistry and Scientific Director of the Joint Center for Artificial Photosynthesis (JCAP) at Caltech. JCAP is one of several federally funded Energy Innovation Hubs, with a specific focus on deriving fuel from sunlight. In a recent talk given at the LAEDC Mid Year Economic Forecast, republished here in VerdeXchange News and TPR, Professor Lewis puts the earth’s current greenhouse gas levels in historic perspective, noting that no energy source has the power to both clean our atmosphere and meet civilization’s growing energy demands except the sun. Yet harnessing the sun’s energy with current solar panel technology presents problems of space and storage. Lewis outlines how artificial photosynthesis might solve these problems, as well as the steps Caltech is taking to make this hypothetical technology a game-changing reality.
