Researchers use quantum computing method to optimize molecular photoswitches for solar energy harvesting

Green Car Congress

Molecular photoswitches that can both convert and store energy could be used to make solar energy harvesting more efficient. The procedure was based on a dataset of more than 400,000 molecules, which the researchers screened to find the optimum molecular structure for solar energy storage materials. 202309543

ORNL demos 20 kW bi-directional wireless charging on UPS PHEV truck; 11" air gap, >92% efficiency

Green Car Congress

With its bi-directional design, the system also supports use of the vehicle’s batteries for energy storage. Doing so would give energy flexibility to a fleet owner’s business, and help better manage on-site generation such as solar power. The technology takes energy from the grid and converts it to direct current (DC) voltage.
