In our May episode of Project Features, H2SITE joined us to explore the development history of their Palladium membrane-based, ammonia cracking technology. Learn more about the deployment of this technology at a hydrogen vehicle refueling site in the UK, plus plans for scaling-up the technology to produce tons per day of fuel-cell grade hydrogen from ammonia.
At last month’s MariNH3 conference in Nottingham, a series of keynotes laid out the opportunities and challenges ahead for marine ammonia fuel. Onboard ammonia cracking technologies are moving through testing phases and closer to commercialisation, vessel designers are working through the unique challenges of carrying ammonia fuel onboard, and emissions mitigation technology (in combination with adherence to existing Tier 3 standards) will be necessary to ensure that ammonia-powered vessels are more environmentally-friendly than conventional counterparts.
JERA and IHI have successfully concluded a large-scale ammonia co-firing trial at the Hekinan power station. For two months, 20% fuel substitution in the 1 GW-sized Unit 4 was achieved, with stable operations throughout. JERA aims to have commercial ammonia co-firing operations up and running by March 2025.
WinGD’s X‑DF‑A dual-fuel engines have been ordered by Singapore-based shipping giant AET for deployment onboard new Aframax tankers, being built in China. Fishing vessels operators Vardin and Framherji have ordered Wärtsilä 25 engines for a series of three fishing trawlers that will operate in the Faroe Islands. In construction news, CMB.TECH will build the Yara Eyde vessel for Yara and North Sea Container Line in China, with vessel delivery scheduled for mid-2026.
Several ammonia-centric vessel designs were granted AiP at the recent Posidonia shipping exhibition in Greece. Lloyd’s Register approved designs including the world’s largest Very Large Ammonia Carrier, a container vessel and a gas carrier propelled by Amogy’s ammonia-to-power technology, a NOX-compliant container vessel featuring a MAN ammonia engine, and an ammonia-powered Very Large Ore Carrier. Lloyd’s Register also recently approved H2SITE’s onboard ammonia cracking technology.
The Ministry of Economy, Trade and Industry has published a regional strategy to decarbonise the power generation ecosystem in the Chugoku region, Japan. The strategy predicts the region will require more than 3 million tons of fuel ammonia by 2030, and highlights several ongoing industrial initiatives to demonstrate the use of ammonia fuel & establish local import infrastructure.
From near-zero volumes today, JERA has set its sights on being a “pioneer player” in the emerging global value chain for ammonia, handling 7 million tons every year by 2035. JERA is also aiming for 100% substitution of ammonia fuel in ultra-supercritical power stations in the 2040s, and to maintain currently low levels of NOX and SOX emissions from its power generating fleet.
2024 has already been a busy year, with ammonia discussions at an exciting phase. Despite the hesitancy and doubts about ammonia I have heard at recent events, I continue to deliver the same constructive messages, and urge the AEA membership and networks to use the information available to continue to promote ammonia. Our upcoming annual event in New Orleans will explore progress in establishing ammonia markets, and I can’t wait to see you all again in-person.
MAN Energy Solutions has announced one of the first deployments of its ammonia two-stroke engine will take place in Japan. Mitsui E&S will construct the MAN B&W 7S60ME dual-fuel engine, with Imabari Shipbuilding to then install it aboard a Newcastlemax bulk carrier, along with an integrated SCR catalytic converter to treat engine NOX emissions. The news underscores significant momentum for the deployment of marine ammonia engines, with Wärtsilä, WinGD and Mitsubishi Shipbuilding also engaged in ongoing projects.
Hitachi Zozen and NYK will work towards a catalyst-based N2O removal system for ammonia-powered, 2-stroke marine engines.
