This paper examines the current development of hydrogen technology in the manufacturing sector and the industrial policies enacted to support it across countries. In addition to continued R&D efforts, governments can already lay the ground for the deployment of green hydrogen by implementing five types of policies: 1) supporting R&D and demonstration for green hydrogen to bring down the cost of electrolysers and make them competitive; 2) increasing the supply of renewable electricity; 3) reducing the cost gap between green hydrogen and brown technologies through a comprehensive policy package, such as carbon pricing and the phasing out of inefficient fossil fuel subsidies; 4) reducing uncertainty, for instance by promoting international standardisation, hydrogen infrastructure, and sound regulatory standards; and 5) considering blue hydrogen as a short-term option to facilitate the transition to green hydrogen.
