Drop-in Solar Fuels from CO2 and H2O: Performance Indicators

In this op-ed, Geoff describes the four performance indicators of CO2 reduction technologies: product selectivity, material stability, mass conversion, and solar-to-fuel energy efficiency. Alone, these indicators may be misleading, but Geoff highlights a report by Steinfeld’s group which reported all … Continue reading
