Presentation

As a resource-constrained nation, Singapore needs to secure long-term supplies of low-carbon energy. Keppel Infrastructure is leading several decarbonization opportunities, including a pathfinder project for ammonia power generation and bunkering on Jurong Island. A series of challenges confronts Singapore as it seeks to secure fuel supplies, including price competitiveness and certification of incoming fuels.

Presentation

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 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.

Presentation

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.

Article

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.

Article

We explore recent, full-scale, dual-fuel engine testing results from leading maritime vendors such as MAN Energy Solutions and WinGD. Testing indicates negligible emissions of the potent GHG N2O (which can be fully eliminated with catalytic treatment), and significantly lower NOX emissions for engines running in ammonia mode, compared to running on fuel oil or diesel. Overall, compliance with IMO Tier II and III emission limits is well within reach for the first generation of ammonia-fueled maritime engines.

In the latest episode of Project Features, Foshan Xianhu Laboratory and Monalisa Group explored a recent demonstration of ammonia combustion for industrial fabrication of ceramic tiles in China. Retrofits of the gas-powered production lines, safe, low-emission ammonia combustion, a multi-level DeNOX approach, target markets, and future ammonia fuel demand potential in China were discussed.
