What this tile covers Using clean electricity to make hydrogen, then fuels and chemicals. Share of use <.01% share of final energy use (2025)

Share of world total final energy consumption (about 435 EJ, calculated: motor systems 13,462 TWh are 53% of electricity, so about 25,400 TWh or 91 EJ, and electricity is about 21% of final energy) that passes through this device or is used by this sector, latest year available. Electricity-based devices use electricity's 21% share of final energy (IEA WEO 2025). Overlaps between devices and sectors are allowed and noted. Just over 4 GW of water electrolysis at an assumed 40% load uses about 14 TWh, yielding at most about 0.035 EJ of hydrogen, about 0.008% of roughly 435 EJ final energy (calculated). Upper bound, since only part of this hydrogen is turned into ammonia, methanol or synthetic fuels. Source: Global Hydrogen Review 2026: Production, International Energy Agency.
