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] 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] Several methods exist for storing . These include mechanical approaches such as using high pressures and low temperatures, or employing chemical compounds that release H2 upon demand. While large amounts of hydrogen are produced by various industries, it is mostly consumed at the site of production, notably for the synthesis of . For many years hydrogen has been stored as compres.
[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.
[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] Hydrogen storage requires either extremely high-pressure tanks or extremely cold temperatures, which means that storage alone consumes a lot of energy. This is why metal hydrides, which can store hydrogen more efficiently, are such a promising option.
