NREL, Berkeley Lab propose efficiency and stability best-practices for solar water-splitting

Green Car Congress

NOVEMBER 2, 2022

Scientists from the US Department of Energy’s National Renewable Energy Laboratory (NREL) and Lawrence Berkeley National Laboratory (Berkeley Lab) are providing researchers with a guide to how best to measure the efficiency of producing hydrogen directly from solar power. PEC water-splitting was first noted in scientific publications in 1972.

New low-cost bio-inspired nanostructured MoS2 catalyst performs almost as efficiently as Pt for hydrogen production

Green Car Congress

DECEMBER 5, 2017

A team led by researchers from Sandia National Laboratories and the University of California, Merced has developed an efficient molybdenum disulfide (MoS 2 ) catalyst for driving the hydrogen evolution reaction (HER). The structures take in an external material to produce hydrogen rather than oxygen, and one day may be powered by sunlight.

5 Hydrogen Hydrogen is a fuel that can be used in two ways in a vehicle. Hydrogen can be burned in an internal combustion engine to power the car to move, or it can be used with oxygen in a fuel cell to run an electric vehicle. Honda Clarity , Toyota Mirai are a few examples of hydrogen-powered vehicles.
