The Global Hydrogen Review is a new annual publication by the International Energy Agency to track progress in hydrogen production and demand, as well as in other critical areas such as policy, regulation, investments, innovation, and infrastructure development. The report examines what international progress on hydrogen is needed to help address climate change – and compares real-world developments with the stated ambitions of government and industry and with key actions under the Global Action Agenda launched at the Hydrogen Energy Ministerial Meeting in 2019. Given the role of hydrogen in addressing climate change, this Review aims to help decision makers fine-tune strategies to attract investment and facilitate deployment of hydrogen technologies while also creating demand for hydrogen and hydrogen-based fuels.
