Diggers, buses and other heavy vehicles have been developed to be powered by hydrogen The possibility of a future powered significantly by clean hydrogen has taken a small step closer. The world’s biggest “green” hydrogen developers have joined forces in what they call the Green Hydrogen Catapult. Their ambition is […]

The Gibson Generating Station is a coal-burning power plant located in Gibson County, Indiana. Credit: Emily Grubert, Georgia Tech Decarbonizing U.S. electricity production will require both construction of renewable energy sources and retirement of power plants now operated by fossil fuels. A generator-level model described in the December 4, 2020, […]

Argonne and SLAC will develop artificial photosynthesis methods to enable direct air capture of CO2 while expanding sources of energy through the conversion of CO2 to fuels and other useful chemicals. Leaves make it look easy, but capturing and using carbon dioxide (CO2) from the air is a challenging process for scientists […]
