WARTSILA TO PERFORM FULL SCALE AMMONIA ENGINE TEST

July 01, 2020

The technology group Wärtsilä, in close customer cooperation with Knutsen OAS Shipping AS and Repsol, as well as with the Sustainable Energy Catapult Centre, will commence the world’s first long term, full-scale, testing of ammonia as a fuel in a marine four-stroke combustion engine. The testing is made possible by a 20 MNOK grant from the Norwegian Research Council through the DEMO 2000 programme.
“This is a great example that illustrates the importance of dedicated petroleum R&D. This DEMO 2000 project is another steppingstone for reaching our ambitious climate targets and it is also aligned with our recently published hydrogen strategy. We need to develop and use new technologies that reduce emissions. We are very happy to support development work that can lead to increased use of ammonia as a fuel in shipping and in the offshore sector. Know-how from this project will also provide important input to the development of regulations for the use of ammonia and other low-carbon fuels”, says Tina Bru, Norwegian Minister of Petroleum and Energy.
Ammonia is promising as a carbon-free fuel for marine applications, in view of the maritime industry’s need to fulfil the International Maritime Organisation’s vision of reducing greenhouse gas emissions from shipping by at least 50 percent by 2050. Furthermore, ammonia has huge potential for providing green energy to remote power systems, such as offshore installations on the Norwegian Continental Shelf.
Development work by Wärtsilä, as it prepares for the use of ammonia as a fuel, continues with this testing programme, which will be the world`s first full-scale four-stroke combustion engine test. The project will commence in the Sustainable Energy Catapult Centre’s testing facilities at Stord, Norway during the first quarter of 2021.
“We are really excited to further develop and understand the combustion properties of ammonia as a carbon free fuel in one of our multi-fuel engines”, says Egil Hystad, General Manager, Market Innovation at Wärtsilä Marine Business.
Wärtsilä, as part of its development work on future fuels, has studied the use of ammonia as a future carbon-free fuel through the ZEEDS initiative. The company’s first ammonia combustions tests were commenced in Vaasa, Finland, in winter 2020, and will continue with this long-term testing at the Sustainable Energy Catapult Centre facilities in Stord.
“We are extremely pleased to be part of this project that will prove for the industry the robustness of ammonia as fuel. The project confirms our test facilities’ and Norway’s leading position within the testing and development of solutions for the use of maritime carbon-free fuels”, says Willie Wågen, CEO of Sustainable Energy Catapult Centre. The centre is part of the Norwegian Catapult programme that facilitates a national infrastructure for innovation. The programme is run by SIVA in close cooperation with Innovation Norway and the Norwegian Research Council and financed by the Norwegian Ministry of Trade, Industry and Fisheries.
The full-scale fuel testing programme can pave the way for ammonia engines to be used in real vessel operations within few years, and several shipowners have shown interest in this possibility. It will also provide important insights into the long-term effect of an ammonia fueled engine in relation to other systems and components in a vessel, including the required safety measures.
