The International Energy Agency (IEA) reports in its ‘Global Hydrogen Review 2021’ report, released on October 4, that although investment is increasing in hydrogen projects to support a clean energy transition, further efforts are needed to reduce costs and encourage wider use across sectors.

As such, the agency says governments need to move faster and more decisively on a range of policy measures to enable low-carbon hydrogen to fulfil its potential to help the world reach net-zero emissions, while also supporting energy security.
