Sandia team boosts hydrogen production activity by molybdenum disulfide four-fold; low-cost catalyst for solar-driven water splitting

Green Car Congress

The improved catalyst has already released four times the amount of hydrogen ever produced by MoS 2 from water. The idea was to understand the changes in the molecular structure of molybdenum disulfide, so that it can be a better catalyst for hydrogen production: closer to platinum in efficiency, but earth-abundant and cheap.

Researchers from MIT and Sun Catalytix develop an artificial leaf for solar water splitting to produce hydrogen and oxygen

Green Car Congress

The traces are for solar cells of 7.7% 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. solar-to-fuels systems. illumination.

Harvard team demonstrates new metal-free organic–inorganic aqueous flow battery; potential breakthrough for low-cost grid-scale storage

Green Car Congress

As the fraction of electricity generation from intermittent renewable sources—such as solar or wind—grows, the ability to store large amounts of electrical energy is of increasing importance. Solid-electrode batteries maintain discharge at peak power for far too short a time to fully regulate wind or solar power output.

BNEF report finds hydrogen promising decarbonization pathway, but carbon prices and emissions policies required

Green Car Congress

The falling cost of making hydrogen from wind and solar power offers a promising route to cutting emissions in some of the most fossil-fuel-dependent sectors of the economy, such as steel, heavy-duty vehicles, shipping and cement, according to a new report from BloombergNEF (BNEF). Abatement cost with hydrogen at $1/kg (7.4/MMBtu).

New Rutgers non-noble metal catalyst for hydrogen evolution performs as well as Pt in both acid and base

Green Car Congress

Currently, renewable hydrogen may be produced from water by electrolysis with either low efficiency alkaline electrolyzers that suffer 50–65% losses, or by more efficient acidic electrolyzers using expensive rare platinum group metal catalysts (Pt). 2 , equivalent to ~10% solar photoelectrical conversion efficiency. Resources.

Exeter team develops low-cost photoelectrode for spontaneous water-splitting using sunlight

Green Car Congress

The nanostructured photoelectrode results in spontaneous hydrogen evolution from water without any external bias applied with a faradaic efficiency of 30% and excellent stability. The researchers believe this new type of photoelectrode is not only cheap to produce, but can also be recreated on a larger scale for mass and worldwide use.
