Hydrogen is an increasingly important piece of the net zero emissions by 2050 puzzle

The key pillars of decarbonising the global energy system are energy efficiency, behavioural change, electrification, renewables, hydrogen and hydrogen‐based fuels, and CCUS. The importance of hydrogen in the Net zero Emissions Scenario is reflected in its increasing share in cumulative emission reductions. Strong hydrogen demand growth and the adoption of cleaner technologies for its production thus enable hydrogen and hydrogen based fuels to avoid up to 60 Gt CO2 emissions in 2021-2050 in the Net zero Emissions Scenario, representing 6% of total cumulative emissions reductions.
