Rice U team creates low-cost, high-efficiency integrated device for solar-driven water splitting; solar leaf

Green Car Congress

Rice University researchers have created an efficient, low-cost device that splits water to produce hydrogen fuel. The integrated device consists of two series-connected perovskite solar cells (PSCs) and two CoP catalyst electrodes, which can be immersed into an aqueous solution directly for solar-driven water splitting.

Swiss team develops effective and low-cost solar water-splitting device; 14.2% solar-to-hydrogen efficiency

Green Car Congress

As the V OC of the presented c-Si cells is only ∼600 mV, four cells need to be connected in series to achieve stable water splitting performance. We demonstrate in this study that, thanks to their high V OC , three series-connected SHJ cells can already stably drive the water splitting reaction at unprecedented SHE. Schüttauf et al.

DOE awarding $35M to 11 projects for hydrokinetic turbine development; ARPA-E SHARKS

Green Car Congress

Hydrokinetic energy is an abundant renewable resource that can boost grid resiliency and reduce infrastructure vulnerability, but it is currently a cost prohibitive option compared to other energy generating sources. The University of Michigan proposes the RAFT concept as a solution for hydrokinetic energy harvesting.

DOE to award almost $20M to new research and development projects for advanced vehicle technologies

Green Car Congress

This topic seeks proof-of-concept, or seedling projects that complement the VTO Battery500 Consortium’s research to more than double the specific energy (to 500 watt-hours per kilogram) of lithium battery technologies which will result in smaller, lighter weight, less expensive battery packs, and more affordable electric vehicles.
