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.
In our April episode of Project Features, we explored Air Liquide’s industrial-scale ammonia cracking pilot unit at the Port of Antwerp-Bruges in Belgium, as well as the emerging standards and regulations around hydrogen and ammonia.
Ammobia has raised $7.5 million for its modular Haber Bosch 2.0 technology, combining proprietary catalysts and sorbents for low-temperature ammonia synthesis. In New Zealand, Liquium has raised NZ$2 million to validate its novel ammonia synthesis catalysts under industrial conditions. And US-based geNH3 has also raised seed funding for its patented Calcium-mediated technology for ammonia synthesis, targeting 5 kg per day production capacity by mid-April.
Duiker Clean Technologies and new partners Plant One have chosen the Port of Rotterdam as the location for the installation of the AMMONEX ammonia cracking pilot plant.
In our latest technology landscape analysis, AEA Technology Manager Kevin Rouwenhorst explores four broad categories for novel ammonia production technologies: improved catalysts, sorbent enhancement, electrochemical ammonia synthesis, and other technology pathways (including geological, single-step and looping synthesis).
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.
US-based Addis Energy announced they have closed an $8.3 million oversubscribed seed round to progress work on subsurface production of ammonia, via the strategic injection of feedstock materials.
One of the key steps in project development remains the selection of the licensor for the renewable ammonia synthesis loop. We explore different technology offerings from leading licensors – including KBR, Topsoe, Thyssenkrupp Uhde, Casale, Stamicarbon, and GoodChina – as well as the growing list of projects where they are being deployed.
