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 to award $35M for bioenergy feedstock and algae R&D

Green Car Congress

DE-FOA-0002423 ) Topic Areas ins the FOA support DOE’s Bioenergy Technologies Office’s (BETO’s) objectives to reduce the minimum selling price of drop-in biofuels, lower the cost of biopower, and enable high-value products from biomass or waste resources. The application process will include two phases: a concept paper and a full application.

NCSU team develops catalyst for thermal hybrid water-splitting and syngas generation with exceptional conversion; H2 gas and liquid fuels

Green Car Congress

Researchers at North Carolina State University have developed a highly effective new perovskite-promoted iron oxide redox catalyst for a hybrid solar-redox scheme they had proposed earlier for partial oxidation and water-splitting of methane. To further enhance this effect, they proposed a layered reverse-flow reactor concept.

DOE to award $33M to advance hydrogen and fuel cell R&D and the H2@Scale vision

Green Car Congress

H2NEW includes National Renewable Energy Laboratory and Idaho National Laboratory as co-leads, and focuses on R&D to enable affordable, durable and efficient large-scale electrolyzers, which produce hydrogen from electricity and water (at both high and low temperatures). Efficient and innovative hydrogen production.

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.

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

Green Car Congress

The University of Michigan proposes the RAFT concept as a solution for hydrokinetic energy harvesting. The innovative new turbine designs, along with distributed load control and regulator concepts, significantly reduce the levelized cost of energy. University of Washington.

EU research project IDEALFUEL seeks to develop marine low-sulfur heavy fuel oils from biomass; Bio-HFO

Green Car Congress

The IDEALFUEL project aims to create sustainable alternatives by developing new efficient and low-cost methods to produce low-sulfur heavy fuel oils from wood-based non-food biomass. Although cleaner fuels are available, many companies opt for HFOs due to their low cost.
