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

Green Car Congress

SHARKS teams will develop new economically competitive Hydrokinetic Turbines (HKT) designs for tidal and riverine currents. 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.

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.
