Hydrogen is produced on a commercial basis today – it is used as a feedstock in the chemical industry and in refineries, as part of a mix of gases in steel production, and in heat and power generation. Global production stands at around 75 MtH2/yr as pure hydrogen and an additional 45 MtH2/yr as part of a mix of gases.
The versatility of hydrogen fuel creates many opportunities to replace fossil fuels in different parts of our economy. It can provide long-term energy storage for the electric power sector, fuel for heavy duty transportation, and heat for industrial processes requiring high temperatures, like steel or concrete production.

Globally, fossil fuels account for a much smaller share of electricity production than the energy system as a whole. This interactive map shows the share of electricity that comes from fossil fuels (coal, oil, and gas summed together) across the world. Oil accounts for only a small share of electricity production – most come from coal and gas.

Executive summary – Global Hydrogen Review 2022 – Analysis
Much of the increase in hydrogen demand in 2021 was met by hydrogen produced from unabated fossil fuels, meaning there was no benefit for mitigating climate change. The production of low-emission hydrogen was less than 1 Mt in 2021, practically all of it coming from plants using fossil fuels with carbon capture, utilisation and storage (CCUS).
