Asia’s transformation in recent decades into a global manufacturing hub has fueled economic growth and lifted millions out of poverty. However, this success has also massively increased the region’s emissions footprint, making it essential for Asia’s industries to rapidly transition to green technologies and processes.

“Green Hydrogen for Decarbonizing Asia’s Industrial Giants” assesses the future potential and trajectory for electrolyzers needed to meet green hydrogen (H2) demand in Asia’s four largest economies: China, India, Japan, and South Korea. The report, which was commissioned by the High-level Policy Commission on Getting Asia to Net Zero and carried out by Global Efficiency Intelligence, highlights the role of manufacturers as agents of change in the Asia’s net zero transition.

The study focuses on the role of green H2 in three priority industries — steel, ammonia, and methanol — under various decarbonization scenarios. In these sectors, green H2 has the capacity to significantly reduce emissions by replacing carbon-intensive processes with renewable energy-powered electrolysis.

Should the four countries adhere to their declared net zero targets, the collective market potential of electrolyzers for these industries is expected to skyrocket to $180 billion by 2050, with a compound annual growth rate as high as 12% between 2030 and 2040. This is nearly five times as large as the market potential under a business-as-usual scenario.

The report offers a suite of recommendations for policymakers, industry players, investors, and think thanks aimed at accelerating the development and adoption of green H2 and electrolyzer manufacturing. These targeted strategies aim to collectively support a robust ecosystem for green H2 production and use in these countries toward a net zero industry.
