Hydrogen produced with renewable energy sources – or “green” hydrogen – has emerged as a key element to achieve net-zero emissions from heavy industry and transport. Along with net-zero commitments by growing numbers of governments, green hydrogen has started gaining momentum based on low-cost renewable electricity, ongoing technological improvements and the benefits of greater power-system flexibility.

Hydrogen-based fuels previously attracted interest mainly as an alternative to shore up oil supply. However, green hydrogen, as opposed to the “grey” (fossil-based) or “blue” (hybrid) varieties, also help to boost renewables in the energy mix and decarbonise energy-intensive industries.
This report from the International Renewable Energy Agency (IRENA) outlines the main barriers that inhibiting green hydrogen uptake and the policies needed to address these. It also offers insights on how to kickstart the green hydrogen sector as a key enabler of the energy transition at the national or regional level.

Key pillars of green hydrogen policy making include:
This is the first guide in a series of reports designed to explore policies to support green hydrogen. The second one, published in May 2021, Green hydrogen supply: A guide to policy making, explored the challenges for green hydrogen production and the third one, published in March 2022, Green hydrogen for industry: A guide to policy making, highlighted the range of policy options available in the industrial sector.
