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 NOX 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.

MEPC 83: global shipping gets its first-ever emissions pricing mechanism

Julian Atchison April 23, 2025

The regulations send a clear signal to industry – business as usual operations will become significantly more expensive, and zero or near-zero (ZNZ) technologies and fuels represent one of the better opportunities to make deep emissions cuts. Following the historic vote at the IMO, we explore critical timelines for the new regulations, compliance thresholds, mechanisms for vessels to comply, and uncertainties that remain.

Adani: critical transmission infrastructure approved for Gujarat ammonia project

Julian Atchison April 22, 2025

Adani Energy Solutions has had a $330 million transmission project approved that will supply power to its renewable hydrogen and ammonia project in Mundra, Gujarat. The first phase of the Mundra Green Hydrogen Hub will feature 1 million tons per year hydrogen production capacity, with ammonia to be utilized for coal co-firing, marine fuel, exports, and as a substitute for current feedstock imports into India.

First ammonia bunker pilot completed in Rotterdam

Julian Atchison April 21, 2025

Facilitated by the Port of Rotterdam, Trammo, OCI, James Fisher Fendercare successfully completed a ship-to-ship transfer of ammonia between two vessels berthed at APM Terminals Maasvlakte earlier this month. The successful pilot raises the Port of Rotterdam’s “Port Readiness Level” for marine ammonia fuel to the deployment phase.

Reducing electrolysis costs, support for first-mover projects in the UK

Julian Atchison April 13, 2025

27 low-emission hydrogen projects have been shortlisted for funding by the UK’s Department for Energy Security and Net Zero, including Statkraft’s marine ammonia fuel project in Shetland. The UK government has also confirmed that it will exempt electricity used in electrolysis from the Climate Change Levy - one of fourteen policy recommendations from the authors of the Splitting the Difference roadmap to reduce the price of producing electrolytic hydrogen in the UK by 58%.
