EPFL solar hydrogen system co-generates heat and oxygen

Green Car Congress

EPFL researchers have built a pilot-scale solar reactor that produces usable heat and oxygen, in addition to generating hydrogen with unprecedented efficiency for its size. This is the first system-level demonstration of solar hydrogen generation. Holmes-Gentle et al.

Photocatalytic optical fibers convert water into hydrogen

Green Car Congress

Researchers at the University of Southampton have transformed optical fibers into photocatalytic microreactors that convert water into hydrogen fuel using solar energy. The researchers have published their proof-of-concept in ACS Photonics and will now establish wider studies that demonstrate the scalability of the platform.

Israeli company reports successful stage 1 testing of solar CO2-to-fuels technology

Green Car Congress

Israel-based NewCO2Fuels (NCF), a subsidiary of GreenEarth Energy Limited in Australia, reported completion of stage 1 testing of its proof-of-concept system for the conversion of CO 2 into fuels using solar energy. Simultaneously, the same device can dissociate water (H 2 O) to hydrogen (H 2 ) and oxygen (O 2 ).

Researchers develop free-standing nanowire mesh for direct solar water-splitting to produce H2; new design for “artificial leaf”

Green Car Congress

The mesh with BiVO 4 nanowire photoanode for water oxidation and Rh-SrTiO 3 nanowire photocathode for water reduction produces hydrogen gas without an electron mediator. When immersed in water with visible light irradiation (? ? In the present study, we developed a new architecture for direct solar water-splitting.

Solar reactor for the two-step thermochemical production of fuels from water and carbon dioxide

Green Car Congress

Schematic of the solar reactor for the two-step, solar-driven thermochemical production of fuels. A team from Caltech, ETH Zürich and the Paul Scherrer Institute have devised a solar reactor for the two-step, solar-driven thermochemical production of fuels. They achieved solar-to-fuel efficiencies of 0.7
