US scientists hit PV water-splitting efficiency of 20.8% – pv magazine International

Rice College engineers achieved record-breaking effectivity for an built-in photoreactor. The gadget produces hydrogen instantly from photo voltaic with 20.8% effectivity. It makes use of an anticorrosion barrier that insulates the semiconductor from water with out interfering with the switch of electrons. The researchers revealed their findings in Communication in Nature. “You want two barrier layers, one to dam water and the opposite to make good electrical contact between the perovskite layer and the protecting layer,” mentioned Austin Fehr, one of many major authors of the research.

Industries of the Future Fortescue (FFI) it says Nikola will personal the Phoenix Hydrogen Hub (PHH) undertaking. The businesses are working in direction of a hydrogen provide settlement to assist Nikola’s zero-emission Class 8 vans. PHH is a fast-to-market, inexperienced hydrogen undertaking in Buckeye, Arizona. Development actions will proceed in phases to scale with demand. Hydrogen manufacturing is predicted in the midst of this decade, however the firms didn’t touch upon the extent of the funding in hydrogen.

Power in Vienna, RheinEnergie, Siemens Power, and Verbund carried out a joint operational take a look at at a mixed warmth and energy plant operated by Wien Energie in Vienna, Austria. The companions are mixing hydrogen with pure fuel. “This take a look at is the primary of its form on the earth of a commercially used fuel and steam turbine plant of this sort of electrical energy,” SAYS Power in Vienna. The fuel turbine mannequin used within the Donaustadt energy plant is utilized in greater than 115 programs in Europe alone.

Wilo launched 4 modular inexperienced hydrogen manufacturing programs. The German firm mentioned that the product is out there in 4 completely different sizes that may generate energy equal to the annual wants of three, 5, or 20 households. The system makes use of electrolysis to transform power into inexperienced hydrogen, however also can run gasoline cells to transform hydrogen again into electrical energy.

Enapter equipped 30 AEM EL 2.1 electrolyzers and 15 DRY 2.1 dryers for a hydrogen refueling station in Japan as a part of a cooperative take care of Tokyo Fuel. The German firm SAYS the Senju station is the primary industrial hydrogen refueling station to make use of AEM electrolysis in Asia. It added that Enapter’s AEM electrolyzers are used to supply hydrogen on web site to refuel automobiles.
