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.
