Springtime for the artificial leaf

Electrochemical scanning probe from solarfuelshub.org

Here in California, not far from the Energy Vulture’s nest, researchers at the Caltech Joint Center for Artificial Photosynthesis are devising systems that use just sunlight to split water into oxygen and hydrogen molecules with an efficiency much higher than regular photosynthesis. It might be a decade before this is fully commercial, but those hydrogen molecules can either be run through fuel cells to produce electricity or they can be converted into liquid fuels by reacting them with carbon monoxide. Either of these will work better than batteries for powering cars because their energy density is much higher than can be achieved with batteries…the cars will have a greater range.
