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. Jan-Willem Schüttauf, Miguel A.

MIT Researchers Identify New Low-Cost Water-Splitting Catalyst

Green Car Congress

Daniel Nocera and his associates have found another formulation, based on inexpensive and widely available materials, that can efficiently catalyze the splitting of water molecules using electricity. Earlier post.). Materials for the new catalyst are even more abundant and inexpensive than those required for the first.

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.

Genifuel Licenses High-yield Algae-to-Natural Gas Process from PNNL

Green Car Congress

PNNL has tested the gasifier with terrestrial plants, kelp and water hyacinths. After condensation, the water enriched with dissolved carbon dioxide is recycled to the growth ponds to accelerate growth of the next generation of biomass while reducing emissions to nearly zero.

Bloom Energy Debuts SOFC Fuel Cell System for Distributed Generation

Green Car Congress

With low cost ceramic materials, and extremely high electrical efficiencies, SOFCs can deliver attractive economics without relying on CHP. Solid State Energy Conversion Alliance (SECA). SOFCs operate at high temperature (typically above 800 °C). Founded in 2001, Bloom Energy can trace its roots to the NASA Mars space program.

Mattershift scales up CNT membranes; potential for zero-carbon fuels for less than fossil

Green Car Congress

Water flow through the membranes was 1000 times higher than predicted by Hagen-Poiseuille flow, in agreement with previous CNT membrane studies. An example of a simplified schematic for converting atmospheric carbon dioxide, water, and solar or wind electricity into ethanol, gasoline, diesel, and jet fuel. McGinnis et al. Background.
