An Overview of Life Cycle Assessment of Renewable Hydrogen

Abstract

Green hydrogen has presented a prominent position in the current global energy transition framework because it has the potential to be used as a feedstock, a fuel or a carrier and storage of clean energy to balance electricity supply and demand. However, a Life Cycle Assessment (LCA) of green hydrogen is needed in order to measure the potential reductions in environmental impacts of large-scale implementation compared to existing technologies. Thus, this paper applies a systematic review with a bibliometric approach of studies on LCA applied to green hydrogen. The results show that studies on the subject are very current and present several practical applications, which are limited by data availability and information generalizations.
