Knutsen OAS Shipping, Wärtsilä, Repsol, and the Sustainable Energy Catapult Centre have announced plans to 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.
Ammonia is a promising fuel option for international shipping to cut greenhouse gas (GHG) emissions and provide green energy to remote power systems, such as offshore installations on the Norwegian Continental Shelf.
Wärtsilä has studied the use of ammonia as a future carbon-free fuel through the Zero Emission Energy Distribution at Sea (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.
Wärtsilä will continue testing through this 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.
“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,” said Tina Bru, Norwegian minister of Petroleum and Energy.
“Ammonia storage and supply systems will be designed and developed for maximum personal safety, and in parallel with the Fuel Gas Handling System under development as part of the EU project ShipFC. This project is coordinated by NCE Maritime CleanTech, and it involves an ammonia driven fuel cell which will be tested on the Eidesvik Offshore supply vessel, Viking Energy,” said Egil Hystad, general manager, Market Innovation at Wärtsilä Marine Business.
“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”, commented 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 fuelled engine in relation to other systems and components in a vessel, including the required safety measures.
“A future implementation of ammonia as a carbon free fuel, combined with clean energy production from offshore wind or other renewable energy sources can be the start of a new industrial era for the Norwegian industry”, Egil Hystad pointed out.
“The Norwegian culture for collaboration and knowledge sharing across different companies and sectors, is a great support in closing big technology gaps. The assistance, cooperation and funding from governmental institutions are essential to drive the change towards a carbon free future”, he continues.
