George Washington University’s Dr. Stuart Licht and colleagues have published the first experimental evidence of their new solar thermal electrochemical photovoltaic (STEP) process, which combines electrical and chemical pathways to convert CO2 to carbon or to carbon monoxide for subsequent use in synthesizing a range of industrially relevant products including hydrocarbon fuels. According to the […]

Chemist Daniel Nocera of MIT made news by trying to mimic photosynthesis, and improve on it. The idea seems simple: split water into hydrogen and oxygen with sunlight, and then recombine them which releases the energy in a fuel cell when the power is needed.  The goal is to do both these things cheaply.  Nocera […]
