Penn State, FSU team develops low-cost, efficient layered heterostructure catalyst for water-splitting

Green Car Congress

A team of scientists from Penn State and Florida State University have developed a lower cost and industrially scalable catalyst consisting of synthesized stacked graphene and W x Mo 1–x S 2 alloy phases that produces pure hydrogen through a low-energy water-splitting process.

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

Green Car Congress

Their high production volumes have largely contributed to a price drop of 80% since 2008, currently reaching levels below $1 per watt peak. 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. Schüttauf et al.

Mangrove raises $3M from BDC Capital to accelerate deployment of battery-grade lithium processing systems

Green Car Congress

Mangrove is the developer of a modular platform for the cost-effective production of battery-grade lithium hydroxide. The platform technology is also being commercialized for conversion of waste brines to chemicals and desalinated water. Lithium processing is presently concentrated in a small number of regions in the world.

Researchers develop free-standing nanowire mesh for direct solar water-splitting to produce H2; new design for “artificial leaf”

Green Car Congress

The mesh with BiVO 4 nanowire photoanode for water oxidation and Rh-SrTiO 3 nanowire photocathode for water reduction produces hydrogen gas without an electron mediator. an “artificial leaf” to produce hydrogen—based on a nanowire mesh that lends itself to large-scale, low-cost production.
