Ammonia power generation for carbon-neutrality

Toshiro Fujimori

In the power generation space, IHI is actively developing ammonia-fueled gas turbines, boilers and diesel engines. Emission control by two-stage combustion helps reduce the generation of harmful NOX pollutants, and a combustor has been successfully developed and tested to power a 2MW gas turbine. Long-term durability testing of the 100% ammonia-fueled IM270 turbine has concluded at IHI’s Aioi facility, and an ongoing partnership with GE Vernova will develop retrofit technology to enable GE’s F-Series turbines to burn 100% ammonia fuel by 2030. IHI is also part of the Hekinan coal co-firing project, developing boilers capable of burning 60% and 100%…

Mitsubishi Hydrogen and Ammonia Gas Turbine

Satoshi Tanimura

Mitsubishi is engaged in many projects related to the full ammonia fuel value chain. While tests for hydrogen firing have already begun for large-scale gas turbines, the focus for ammonia fuel is currently on small-size models, and the demonstration of a 100% ammonia fuel combustor.  The presentation also explores the design considerations for an ammonia-fueled gas turbine, including safety systems and fuel supply.

Safety approach and protocols applied in ammonia marine fuel: trials in the Port of Singapore

Eric Chua

This presentation explores operational learnings from a key ammonia fuel trial undertaken by the Maritime & Port Authority of Singapore – the sailing of the Fortescue Green Pioneer – as well as the establishment of the Maritime Energy Training Facility, which features a dual fuel marine engine simulator for training on the safe handling, bunkering and management of incidents.

Ammonia Skills & Training
Presentation

Ammonia Skills & Training

Brian Inglis

In anticipation of new ammonia production projects beginning operations in Australia, how do we supply and train the new personnel that will be required? This was the focus of the CQU Ammonia Skills Project 2024/25, which produced new module training packages that have been piloted and validated by industry. The workshop also looks at training from a risk management perspective, and what lessons can be drawn from the rise of LNG manufacturing in Australia.

JERA’s Decarbonization Initiatives: Exploring results from the ammonia power generation demonstration at Hekinan

Masaki Ichiryu

In order to achieve decarbonization of thermal power plants, we conducted a demonstration test at the Hekinan Thermal Power Plant to substitute a part of coal fuel with ammonia fuel last year. The demonstration test was conducted by substituting 20% of the coal fuel with ammonia with good results, and now our construction is progressing as planned for commercial operation. In addition, we have considered safety measures for ammonia handling, including facility design and operational considerations, and we conducted disaster prevention drills and communicated with the local community. In this session, I will explain & explore these initiatives.

Emission performance of ammonia-fueled, four-stroke marine engines

Kevin Rouwenhorst June 03, 2025

We explore recent, full-scale, four-stroke engine testing results from IHI and Wärtsilä. Testing indicates N2O emissions can be almost fully eliminated with catalytic treatment, and significantly lower NOX emissions for engines running in ammonia mode, compared to running on diesel. While ammonia slip remains a key consideration due to the design of a four-stroke engine, catalytic treatment of the exhaust can eliminate even high concentrations, and release mitigation systems have already been designed and deployed to ensure safe operations.
