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 NO_X 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.

Marubeni & Exxon: CCS-based ammonia from the Gulf Coast to Japan

Geofrey Njovu May 12, 2025

Marubeni will offtake about 250,000 tons per year of CCS-based ammonia from ExxonMobil’s Baytown Texas facility, to be co-fired at the Kobe power plant in Japan. Marubeni joins Trammo, ADNOC, Mitsubishi, Air Liquide and SK Inc. as project partners, with a series of offtake agreements already signed.

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

Kevin Rouwenhorst May 06, 2025

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 NO_X 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.

Ammonia fuel for industrial ceramics manufacturing

Kevin Rouwenhorst May 02, 2025

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 DeNO_X approach, target markets, and future ammonia fuel demand potential in China were discussed.

IHI completes successful co-firing trial in Indonesia

Julian Atchison April 21, 2025

IHI Corporation, state-owned utility PLN Indonesia Power, and state-owned fertilizer company Pupuk have announced the successful completion of an ammonia co-firing trial at the Labuan power plant on Java’s west coast.

Industrial demonstration of ammonia cracking: exploring global progress

Kevin Rouwenhorst April 16, 2025

Here, we explore the current demonstration landscape for large-scale cracking. To produce pipeline-quality hydrogen at future energy import hubs, industrial-scale ammonia cracking is still to be derisked and demonstrated, although certain parts of the overall process have been proven at scale. What are the technology elements to be considered, and who are the first-movers deploying the technology in a variety of global locations?

Commercial-scale testing of ammonia heat for cement manufacturing in Japan

Geofrey Njovu March 27, 2025

MUCC has commenced commercial-scale testing of ammonia co-firing in the cement manufacturing process. The company is targeting a calorific replacement ratio of 30% for both the calciner and cement kiln.

Hanwha, Baker Hughes to develop fuel-flexible small-size turbines for maritime propulsion

Julian Atchison March 11, 2025

The pair will jointly develop a new small-size, 100% ammonia-capable turbine for maritime applications. Tests will be completed by the end of 2027, after which the ~16 MW unit will be commercially available for orders.

Ammonia combustion for industrial fabrication of ceramic tiles in China

Julian Atchison

Meet Foshan Xianhu Laboratory and Monalisa Group, two partners in an ammonia for heat demonstration project in China. In September 2024, ammonia fuel completely replaced gas in one production line for manufacturing of ceramic tiles at Monalisa’s Guangdong plant. The fuel switch did not compromise the color and quality of the produced ceramic tiles, and partners are working to roll ammonia fuel out onto other production lines.
