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.

NSF/DOE partnership to award up to $18M for H2 production via advanced solar water-splitting technologies; separate DOE solicitation

Green Car Congress

A key benefit of this joint effort is the direct coordination of NSF-funded use-inspired basic research and EERE-funded applied R&D toward the development of cost-effective large-scale systems for the low-carbon production of hydrogen through advanced solar water-splitting technologies.

Georgia Tech team develops highly efficient multi-phase catalyst for SOFCs and other energy storage and conversion systems

Green Car Congress

The catalyst is also readily applicable to other energy storage and conversion systems, including metal-air batteries, supercapacitors, electrolyzers, dye-sensitized solar cells, and photocatalysis. The catalyst is applied as a sheer coating only about two dozen nanometers thick and comprises two connected nanotechnology solutions.

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.
