BMW Group sourcing aluminum produced using solar energy from EGA

Green Car Congress

The BMW Group will begin sourcing aluminum produced using solar electricity with immediate effect. The use of solar electricity is therefore an effective lever for reducing the CO 2 emissions associated with aluminum smelting. The use of solar electricity for producing aluminum is a major step in this direction.

University of Houston team demonstrates new efficient solar water-splitting catalyst for hydrogen production

Green Car Congress

Researchers from the University of Houston (UH) have developed a cobalt(II) oxide (CoO) nanocrystalline catalyst that can carry out overall water splitting with a solar-to-hydrogen efficiency of around 5%. The generation of hydrogen from water using sunlight could potentially form the basis of a clean and renewable source of energy.

CU-Boulder team develops more efficient isothermal solar-thermal water splitting technique for H2 production

Green Car Congress

A University of Colorado Boulder team has developed a new solar-thermal water-splitting (STWS) system for the efficient production of hydrogen. STWS cycles have long been recognized as a desirable means of generating hydrogen gas (H 2 ) from water and sunlight, the team notes. Hydrogen Production Solar'

Duke team develops new core-shell copper nanowire catalyst for efficient water oxidation for solar fuels

Green Car Congress

A transparent film of copper nanowires was transformed into an electrocatalyst for water oxidation by electrodeposition of Ni or Co onto the surface of the nanowires. Water oxidation (2H 2 O → O 2 + 4 e- + 4H + ) is a key step for converting solar energy into chemical fuels. Chen et al. Click to enlarge. times more light.

Researchers at UC Santa Barbara develop efficient and stable plasmonic water splitter; potential alternative to semiconductor-based solar conversion

Green Car Congress

Researchers at UC Santa Barbara have developed an efficient, autonomous solar water-splitting device based on a gold nanorod array in which essentially all charge carriers involved in the oxidation and reduction steps arise from the hot electrons resulting from the excitation of surface plasmons in the nanostructured gold (plasmonic water-splitter).
