Recent Research in Solar-Driven Hydrogen Production

Sustainability, Journal Year: 2024, Volume and Issue: 16(7), P. 2883 - 2883

Published: March 29, 2024

Climate concerns require immediate actions to reduce the global average temperature increase. Renewable electricity and renewable energy-based fuels chemicals are crucial for progressive de-fossilization. Hydrogen will be part of solution. The main issues considered growing market H2 “green” feedstock energy that should used produce H2. electrolysis water using surplus is an important development. Alternative production routes replace fossil fuels. We firstly investigated these alternative through bio-based methanol or ethanol ammonia from digesting agro-industrial domestic waste. catalytic conversion CH4 C was examined as a possible option decarbonizing natural gas grid. Secondly, splitting by reversible redox reactions examined, but supply deemed necessary. application heat power therefore investigated, with special focus on concentrated solar tower (CST) technology. finally assessed valorization data provide tentative view scale-up potential economic aspects systems determine needs future research developments.

Review of Sustainable Hydrogen Energy Processes: Production, Storage, Transportation, and Color-Coded Classifications

Energy & Fuels, Journal Year: 2024, Volume and Issue: unknown

Published: Nov. 18, 2024

Rapid urbanization and population growth have intensified global energy demand, with fossil fuel consumption aggravating air pollution climate change. Hydrogen, a clean carrier, is essential for transitioning to low-carbon economy. This study examines the color-coded classification of hydrogen production pathways, derived from both renewable non-renewable sources, their emission profiles. Additionally, it delves into critical aspects storage transportation, highlighting need robust infrastructure ensure effective integration system. The concludes that traditional methods, such as coal gasification steam methane reforming (SMR), significantly contribute due reliance on fuels lack carbon capture. While blue hydrogen, utilizing capture (CCS), offers reduction in greenhouse gas (GHG) emissions, turquoise green produced via pyrolysis water electrolysis, respectively, present cleaner alternatives zero GHG emissions. With regard storage, metal complex hydrides emerge cost-effective options, while compressed suitable large-scale storage. For applications demanding high density, liquefied cryo-compressed are viable, despite associated costs complexities. pressurized tanks, cryogenic liquid tankers, pipelines considered. Pipelines favored long-distance transportation cost-effectiveness, tankers preferred short distances, higher requirements.
