Ammonia-powered vessels & maritime engines: development updates
This week we explore four announcements in the maritime ammonia space:
- Færder Tankers Norway will receive $20 million in Enova funding to develop two ammonia-powered vessel designs: a tanker and a car carrier.
- Mitsubishi Shipbuilding has completed a conceptual design for an LPG-ammonia dual-fuel VLGC, with Approval in Principle granted by ClassNK.
- Delivery dates have been set for the first eight of Höegh Autoliners’ Aurora-class, ammonia-powered car carriers, with China Merchants Heavy Industry to deliver vessels from late 2024.
- WinGD and Hyundai Heavy Industries will collaborate to deliver the first WinGD two-stroke engine capable of running on ammonia by 2025.
Dual-fuel ammonia for power generation in South Korea
New ammonia-powered vessels: Newcastlemax & Panamax class
Ammonia combustion analysis: powertrains, turbines & power generation
This week we explore four updates in ammonia combustion R&D:
1. A team from the University of Cambridge has shown merchant vessels are the strongest candidates for conversion to run on ammonia powertrains, with cargo capacity losses of 4-9% able to be feasibly offset by operators.
2. Researchers at the University of Minnesota have successfully tested a thermochemical recuperation (TCR) reactor to improve the efficiency of a dual-fuel, diesel-ammonia compression ignition engine by minimising ammonia slip.
3. A global team led by Cardiff University researchers has revealed some of the inner workings of ammonia combustion in gas turbine flames.
4. A global team has produced a cradle-to-gate environmental assessment for ammonia production and ammonia-based electricity generation, suggesting that renewable and nuclear ammonia have a significant role to play in decarbonising the power sector.
