Despite technical and economic barriers, ongoing advancements in catalyst development, material optimization, and artificial intelligence-driven energy management systems are accelerating the adoption of solar hydrogen technologies.
[pdf] This work addresses a numerical investigation of hydrogen production by steam gasification of biomass, assisted by concentrated solar energy. Air, heated by an innovative hierarchical volumetric receiver installed on a solar dish, powers the steam gasifier.
[pdf] With natural sunlight and real seawater as the sole inputs, we experimentally demonstrate a 12.6% solar-to-hydrogen conversion efficiency and a 35.9 L m −2 h −1 production rate of green hydrogen under one-sun illumination, where additional 1.2 L m −2 h −1 clean water is obtained as a byproduct.
[pdf] The nickel–hydrogen battery combines the positive nickel electrode of a nickel–cadmium battery and the negative electrode, including the catalyst and gas diffusion elements, of a . During discharge, hydrogen contained in the pressure vessel is oxidized into water while the nickel oxyhydroxide electrode is reduced to nickel hydroxide. Water is consumed at the nickel electrode and produced at the hyd.
[pdf] The iceberg shape like condenser can efficient collect vapor in hot weather. The introduction of a TG between photothermal and evaporation layer can decrease heat loss. Excellent durability performance in solar steam desalination. This ISWG may pave the way for industrial desalination.
[pdf] The Pingmei Shenma Group is actively developing Asia’s first large-scale deep salt cavern hydrogen storage project in Beipangzhuang Village, Xiantai Town, Ye County, Pingdingshan City, Henan Province. This project is set to become China’s largest salt cavern hydrogen storage facility.
