2025: an ammonia energy rollercoaster

Julian Atchison December 17, 2025

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.

Status of renewable ammonia projects and technology licensors

Kevin Rouwenhorst November 18, 2025

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.

Powering the Seas Together

Luca Pilenga Semi Kim Jeff Benoit

In February 2025, Baker Hughes and Hanwha agreed to jointly develop a new small-size (~16 MW power range), 100% ammonia-capable turbine for maritime propulsion applications, to be deployed onboard Hanwha Ocean’s LNG carriers and container ships by 2028. A full gas turbine factory engine test with 100% ammonia is planned to be completed by the end of 2027. The combustion system itself is being developed by Power Systems Mfg., LLC (PSM), and will enable the turbine to be both fully decarbonized and “fuel-flexible” – 100% ammonia combustion to 100% natural gas combustion, and any variable blend in between while meeting…

Innovative Integration of Ammonia Cracking and Power Generation: Hanwha Impact’s H2ACT-HRSG Project

Tuan Hoang

The Hanwha Impact H2ACT-HRSG project introduces a novel and highly efficient flow-scheme that integrates ammonia cracking with heat recovery steam generation (HRSG), tailored for small-to-medium scale clean power applications. Developed in collaboration with KBR, this configuration leverages high-grade heat from gas turbine exhaust and duct firing to drive a series of adiabatic reactors, enabling efficient hydrogen production from ammonia while simultaneously generating steam for power. This innovative integration—termed H2ACT-HRSG—offers performance advantages over conventional stand-alone ammonia cracking systems in combined cycle power generation settings. Key benefits include enhanced hydrogen yield, improved net power generation, and reduced specific ammonia consumption, all contributing…
