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.

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

Green Car Congress

They will incorporate experts in hydrodynamics, structural dynamics, control systems, power electronics, grid connections, and performance optimization. The bottom, sides, and surface of rivers and tidal channels confine water flow, which significantly alters the operation of river and tidal turbines. University of Washington.

KIST team develops membrane reactor system to produce pure H2 from ammonia with high productivity

Green Car Congress

The steam carrier presents similar membrane reactor performance to that of noble gases, and the water reservoir used for steam generation acts as an ammonia buffer via scrubbing effects. The research team at KIST developed a low-cost membrane material and a catalyst for decomposition of ammonia into hydrogen and nitrogen.

Researchers from MIT and Sun Catalytix develop an artificial leaf for solar water splitting to produce hydrogen and oxygen

Green Car Congress

Researchers led by MIT professor Daniel Nocera have produced an “artificial leaf”—a solar water-splitting cell producing hydrogen and oxygen that operates in near-neutral pH conditions, both with and without connecting wires. aligned with the low-cost systems engineering and. Earlier post.).

ARPA-E announces $98M in funding for 40 OPEN projects; two opposed-piston engines projects receive $10M total

Green Car Congress

A motor-generator integrated on each engine crankshaft will provide independent control to each piston and eliminate all torque transmitted across the mechanical crankshaft connection, thus reducing engine size, mass, cost, friction, and noise. Metal-Supported SOFCS for Ethanol-Fueled Vehicles – $3,170,000. University of Delaware.
