ARPA-E awards $175M to 68 novel clean energy OPEN 2021 projects

Green Car Congress

The new superjunction structure will surpass the theoretical trade-off between on- resistance and breakdown voltage observed in conventional unipolar GaN, leading to more efficient and cheaper power converters. Early work has shown very fast reaction kinetics, and power capabilities in excess of 5kW/Kg have been demonstrated.

OSU team develops new aqueous lithium-iodine solar flow battery; 20% energy savings over Li-I batteries

Green Car Congress

The square piece of solar cell (center) is red, because the researchers are using a red dye to tune the wavelength of light it absorbs and converts to electrons. Aqueous flow batteries have attracted significant interest because they could theoretically provide affordable power grid-level energy storage someday.
