Hydrogen is also used for grid-scale energy storage in the power sector and as a clean fuel for thermal power plants. In the steel and chemicals industries, hydrogen-based technologies are gaining acceptance, along with the need to comply with stricter emission regulations. Such multi-sectoral adoption of hydrogen is gaining traction in Japan, hence creating demand for hydrogen generation.

Strengthened Global Partnerships for Hydrogen Supply Chains

Japan is engaged in international partnerships towards developing a good hydrogen supply chain. Contractual ties with renewable energy-sufficient countries have allowed for the import of low-cost hydrogen. Joint ventures are aimed at scaling production, researching of improved storage and transportation technologies, and an assured supply. For instance, in October 2024, Airbus UpNext and Toshiba Energy Systems agreed to co-develop a two-megawatt superconducting motor for hydrogen-powered aircraft, leveraging -253°C liquid hydrogen for fuel and cooling. These partnerships are critical for Japan to supply the consumption demand for hydrogen while ensuring energy security. Japan is reinforcing its role in the global hydrogen market by providing opportunities for faster transitions to an economy backed by hydrogen.

Japan Hydrogen Generation Industry Segmentation:

Analysis by Technology:

Coal Gasification

Steam Methane Reforming

Others

Coal gasification is a technology that converts coal into syngas, a mixture of hydrogen, carbon monoxide, and methane through a high-temperature reaction with controlled oxygen and steam. It is a transitional technique used in Japan's hydrogen generation sector to manufacture hydrogen on a large scale as renewable energy infrastructure keeps growing. This technology guarantees a steady supply of hydrogen for industrial uses and helps the nation achieve its energy diversification objectives. In line with Japan's carbon neutrality goals, ongoing developments seek to increase efficiency and lower carbon emissions.

Steam methane reforming (SMR) is a widely used technology that extracts hydrogen from methane-rich natural gas through a high-temperature reaction with steam. SMR is a key component of the hydrogen generation business in Japan since it is an affordable way to manufacture hydrogen in large quantities for use in electricity, transportation, and industry. Japan is investing in carbon capture and storage (CCS) technology to reduce related emissions, even though SMR presently dominates hydrogen generation. With this strategy, SMR can act as a stopgap measure while the nation develops its green hydrogen infrastructure.
