ASU and Argonne researchers report progress on artificial leaf for solar conversion of water to H2 and O2

Green Car Congress

Researchers at Arizona State University and Argonne National Laboratory reported advances toward perfecting a functional artificial leaf in a paper in Nature Chemistry. The researchers took a closer look at how nature had overcome a related problem in the part of the photosynthetic process where water is oxidized to yield oxygen.

PNNL study finds 2028 grid resource adequacy likely sufficient for high EV penetration; managed charging strategies can double adequacy

Green Car Congress

No new hydropower generation is expected because hydropower generation is energy limited—no more water is expected in the Columbia River system. Managed charging has significant operational benefits in solar-rich areas such as California. Managed charging could reduce the curtailment the most by an additional 16%.
