Solar fuels, such as hydrogen, store solar energy in chemical bonds that can be released on demand, providing a flexible and long-term energy storage solution.
[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] 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] 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] Hydrogen’s energy per unit volume is significantly lower than fossil fuels, requiring four times the storage space of gasoline for equivalent energy content. This complicates mobile applications (e.g., vehicles) and increases infrastructure footprints for solar-to-hydrogen projects.
