Mitsubishi Heavy Industries to explore ammonia-fired gas turbines in Singapore, Indonesia

Jurong Island

MHI, Keppel Infrastructure and DNV have agreed to explore the feasibility and deployment of an ammonia-fired gas turbine on Jurong Island, Singapore. DNV will conduct a high-level, quantitative risk assessment for the use of 100% ammonia in a combined cycle gas turbine (CCGT), with a focus on maintaining high efficiency and low NOx emissions during operation. MHI will develop the gas turbine itself, with Keppel Infrastructure to assess the feasibility of a utility-scale, ammonia-fed power generation plant on Jurong Island.

The new agreement follows Keppel’s announcement in August that it will develop Singapore’s first hydrogen-ready power plant in the Sakra sector of Jurong Island. The 600 MW CCGT Sakra Cogen Plant will be completed by 2026.

Deploying the H-25 turbine in Indonesia

MHI and Bandung Institute of Technology (ITB) will work together to demonstrate 100% ammonia firing with MHI’s H-25 Series, 40 MW gas turbine. Post-demonstration, the pair will then work towards deploying the ammonia-fired H-25 in commercial applications. MHI first announced it was working towards commercialisation in March 2021.

This research collaboration between ITB and MHI focuses on the use of NH3 in power generation, greater adoption of which will help reduce the use of coal. In the long term, production of NH3 will hopefully comprise more green NH3 that uses renewable energy. I hope this joint R&D will have a positive impact on efforts to make a sustainable energy transition.

Both announcements came at the 2nd Asia Green Growth Partnership Ministerial Meeting in Tokyo. The first edition of the annual meeting in 2021 highlighted the future role of hydrogen & ammonia fuel, and kicked off a series of agreements between Japan and ASEAN countries to adopt ammonia energy solutions.
