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] Discover the latest hydrogen policy developments in Q1 2025, with a focus on production targets and funding initiatives across APAC, EMEA, and the Americas. Key updates include changes to the US 45V hydrogen tax credit and Australia's AUD$1bn green iron fund.
[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] 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] 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.
