The view from Japan: 2025 shaping as a pivotal year for ammonia energy

Julian Atchison February 26, 2025

In 2025, the pieces are rapidly assembling to enable and accelerate imports of ammonia energy to Japan. This year, government agency METI is due to announce two lots of key funding, including contracts for difference subsidies and development of import infrastructure. Power generation technologies will be commercialised within the next few years, and more maritime players are joining the push to deploy ammonia fuel in Japanese ships.

Paving the way for ammonia as a marine fuel: insights into the IMO’s Interim Guidelines

Andrea Guati Rojo January 27, 2025

To explore the interim fuel guidelines and discuss their implications, we were joined by the IMO and Lloyd’s Register. Properly applied, the new fuel guidelines will ensure that ammonia systems achieve safety standards comparable to those of LNG or other alternative fuel systems, with special provisions made to ensure that ammonia’s hazards are effectively managed well within acceptable risk thresholds.

Ammonia Energy Conference 2024: Ammonia for Maritime Propulsion is full speed ahead!

Kevin Rouwenhorst November 26, 2024

During the recent 2024 Ammonia Energy Conference, we explored all the latest developments in ammonia-powered maritime propulsion. Engine makers reported strong progress ahead of deployment in 2026, the same year that large-scale vessels will hit the water. The panel explored early operations for the ammonia-powered A-Tug in Japan, as well as ancillary technology systems required for maritime ammonia engines, catalyst after-treatment systems for emission mitigation, and the potential for fuel additives to boost ammonia engine performance.

Sunborne reborn!

Bill David

Despite successfully demonstrating 56kW of controlled combustion of partially cracked ammonia in October 2023, Sunborne Systems was unable to secure Series A funding at the beginning of 2024. Since then, the co-founders have secured UK government funding to tackle two of the challenges set out for Series A funding: to further develop their patented catalysts and to address issues associated with ammonia slippage and NOx emissions. Future opportunities will be discussed.
