In our latest episode of Project Features, we explore EXMAR’s new ammonia dual fuel vessels, which are shortly to go through sea trials on ammonia fuel. We discuss safety engineering, engine testing, crew training, and “Risk Based Certification”: the approvals process novel vessels like these need to go through to demonstrate an equivalent level of safety to that achieved with conventionally-fueled vessels.
Wärtsilä has announced an upgraded version of its four-stroke Wärtsilä 25 Ammonia engine will be available for delivery from 2028, matching the power level of its analog LNG‑fueled engine.
Eidesvik Offshore has signed a contract with a Norwegian shipyard for the retrofit of the platform supply vessel Viking Energy to run on ammonia fuel, which will be completed later in 2026.
Engine testing approval clears another hurdle for the vessels to hit the water and enter commercial service, with EXMAR planning sea trials “in the coming months”.
Wärtsilä will provide its four-stroke, ammonia-powered engine to Skarv Shipping Solutions for deployment on a new timber transport vessel to be built in China. Delivery of the full equipment set – including fuel gas supply system, release mitigation system, and a selective catalytic reduction system for exhaust treatment – is anticipated in late 2026.
In our December episode of Project Features, we explore ammonia energy R&D, pioneering demonstration plants, and start-up companies originating from the University of Minnesota, USA.
Despite the successes and progress made in 2025, the year remains a missed opportunity for ammonia energy. The first complete supply chains for renewable ammonia are emerging, and some 600,000 tons of annual production capacity is set to be online in northeast China early next year. Maritime engines, cracking, and power & heat technology solutions also made their mark, moving from feasibility into deployment. But disappointing outcomes at the IMO and government support that failed to spark market development remains an issue, with plenty of critical, detail-heavy work ahead of us in 2026.
Everllence has launched its new dual-fuel ME-LGIA (Liquid Gas Injection Ammonia) engine at an industry event in Copenhagen, ahead of the first units being delivered next year.
The newly established UK Ammonia Alliance intends to promote the growth of the ammonia industry in the UK, building on the country’s robust research and innovation base.
