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.

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. aligned with the low-cost systems engineering and.

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.

Brookhaven team develops molybdenum-soy catalyst that rivals performance of noble metals for hydrogen production

Green Car Congress

The hybrid material effectively catalyzes the conversion of liquid water to hydrogen gas while remaining stable in an acidic environment. Researchers at the US Department of Energy’s Brookhaven National Laboratory (BNL) have developed a low-cost, stable, effective catalyst made from earth-abundant molybdenum and common soybeans (MoSoy).

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

Green Car Congress

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. A promising way of storing solar energy is via chemical fuels, in particular hydrogen as it is considered as a future energy carrier. —Pawar and Tahir. Govinder S.

Bio-inspired molybdenum sulfide catalyst offers low-cost and efficient photo-electrochemical water splitting to produce hydrogen

Green Car Congress

The incomplete cubane-like clusters (Mo 3 S 4 ) efficiently catalyze the evolution of hydrogen when coupled to a p-type Si semiconductor that harvests red photons in the solar spectrum. When sun hits the PEC cell, the solar energy is absorbed and used for splitting water molecules into its components, hydrogen and oxygen.

All the wind farms and solar panels in the world won’t do anything to lower the outflow of hundreds billions of dollars annually or decrease our pump-fueled funding of Islamic fundamentalism unless we build cars that can use that cleaner electricity. I will pay nothing for my 300 mile road trip.)
