Indonesia, with its substantial renewable energy potential of 3,687 GW, is embracing green hydrogen as a crucial element for accelerating decarbonization in energy-intensive sectors like industry and transportation. The Institute for Essential Services Reform (IESR) emphasizes the importance of developing a detailed green hydrogen roadmap to achieve sustainable and competitive production by 2030. Collaboration with the UK under the Green Energy Transition Indonesia project aims to establish the Indonesia Green Hydrogen Accelerator to align with the National Hydrogen Strategy 2023. The focus is on reducing production costs, enhancing infrastructure, and emulating successful models like the UK's Low Carbon Hydrogen Standard. Challenges include addressing high gas subsidies and implementing carbon pricing mechanisms to ensure green hydrogen's viability and support Indonesia's net-zero target and energy security.
