Effect of Hydrogen Leakage on the Life Cycle Climate Impacts of Hydrogen Supply Chains

Communications Earth & Environment
Abstract Hydrogen is of interest for decarbonizing hard-to-abate sectors because it does not produce carbon dioxide when combusted. However, hydrogen has indirect warming effects. In this work, we conducted a life cycle assessment of electrolysis and steam methane reforming to assess their emissions while considering hydrogen’s indirect warming

Risk Analysis of Hydrogen Leakage at Hydrogen Producing and Refuelling Integrated Station

Processes
Hydrogen energy is considered the most promising clean energy in the 21st century, so hydrogen refuelling stations (HRSs) are crucial facilities for storage and supply. HRSs might experience hydrogen leakage (HL) incidents during their operation. Hydrogen-producing and refuelling integrated stations (HPRISs) could make thermal risks even more prominent
