This info-pack presents the environmental assessment of the proton ceramic electrochemical reactor (PCER) within the SINGLE project, using both Life Cycle Assessment (LCA) and Renewable Energy Directive III (RED III) methodologies. The study compares the two approaches, highlighting how the broader scope of the LCA results in a higher calculated carbon footprint. Under the assessed conditions, the PCER operation remains below the RED III threshold for renewable hydrogen, confirming its environmental compatibility for sustainable ammonia-to-hydrogen conversion.
