Debunking The Myth: Hydrogen Fuel Cells Aren’t More Efficient Than Alternatives

5 min read

Hydrogen is often promoted as a clean and efficient energy carrier, but its real-world efficiency is frequently overstated. Proponents of hydrogen fuel cells highlight their conversion efficiencies of 50–60%, comparing them favorably to internal combustion engines (ICEs). However, this selective framing ignores the full energy pathway, from hydrogen production to … [continued]
