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

Green Car Congress

Photoelectrochemical (PEC) water-splitting, which relies on sunlight to split water into oxygen and hydrogen, stands out as potentially one of the most sustainable routes to clean energy. PEC water-splitting was first noted in scientific publications in 1972. NREL set the first record for STH efficiency exceeding 10% (12.4%

New photoelectrode with enhanced visible light absorption for improved solar water-splitting for hydrogen production

Green Car Congress

A team of researchers at Ulsan National Institute of Science and Technology (UNIST), Korea University, and the Korea Advanced Institute of Science and Technology (KAIST) has developed a new type of multilayered (Au NPs/TiO 2 /Au) photoelectrode that could boost the ability of solar water-splitting to produce hydrogen.

SpaceX to launch NASA’s SWOT water topography satellite on reused Falcon 9

Teslarati

NASA has modified a contract with SpaceX to allow the company to launch the international Surface Water and Ocean Topography (SWOT) mission on a flight-proven Falcon 9 booster. The agency awarded SpaceX an unusually expensive $112 million contract in November 2016 to launch SWOT on a Falcon 9 rocket in April 2021.

DOE: on-road vehicles were responsible for 76% of transportation energy use in 2016

Green Car Congress

quadrillion Btu (quads) of energy in 2016 with 76% of that used by vehicles on the nation’s roads, according to the US Department of Energy (DOE). Light vehicles, including cars, motorcycles, pickups, vans and sport utility vehicles, used the most energy, accounting for 55% of the total. The transportation sector used about 27.8

This Idea Wasn't All Wet: The Sensing Water-Saving Shower Head Debuts

Cars That Think

He imagined a shower head that would sense when the person showering moved out from under the stream of water. The shower head would then automatically turn the water off, turning it back on again when the person moved back into range. With such a device, he thought, people could enjoy a long shower without wasting water.

Detailed snapshots of photosynthesis at room temperature using SLAC’s X-ray laser show water-splitting reaction

Green Car Congress

One of its molecular mysteries of photosynthesis involves how the photosystem II protein complex harvests energy from sunlight and uses it to split water into hydrogen and oxygen. In previous high-resolution studies of the system at synchrotron light sources, samples experienced radiation damage from longer exposure to X-rays.
