HyperSolar reaches 1.25 V for water-splitting with its self-contained low-cost photoelectrochemical nanosystem

Green Car Congress

volts (V) of water-splitting voltage with its novel low-cost electrolysis technology. The theoretical minimum voltage needed to split water molecules into hydrogen and oxygen is 1.23 Nanosystem for water electrolysis. HyperSolar, Inc. announced that it had reached 1.25 V (at 25 °C at pH 0). Click to enlarge.

SDSU-led project to design bacteria that extract rare earth elements in DARPA EMBER project

Green Car Congress

Understanding this process will inform the creation of synthetic designer proteins that bind with high specificity to different types of lanthanides, according to biochemist John Love. This bioprinting technology is low-cost and scalable and is projected to result in significant savings when applied broadly to mineral recovery.

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.

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

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.
