Summary:
- Hydrogen is promoted as a clean energy carrier, but its real-world efficiency is often overemphasized.
- Supporters highlight fuel cell conversion efficiencies of 50-60%, favorably comparing them to internal combustion engines (ICEs).
- This comparison overlooks the full energy pathway from hydrogen production to usage.
Author’s Take:
Despite the touted advantages of hydrogen fuel cells, the full picture of efficiency considering the entire energy pathway should be carefully analyzed to understand their true impact and feasibility in terms of clean energy solutions.
