Finland-headed energy and marine technology group Wärtsilä Oyj, along with Norway-based Höegh LNG AS and other partners including the Institute for Energy Technology (IFE), University of South-East Norway, Sustainable Energy, and BASF SE, has received approximately EUR 5.9 million in project funding from the Norwegian Government.

The project aims to further the development of ammonia as a hydrogen carrier for the energy market.
The funding is a part of Norway’s Green Platform program of initiatives and amounts to approximately 50 percent of the total budget for the joint project.
Ammonia suitable as a hydrogen carrier
The project is designed to enhance the availability of large-scale storage and transportation capabilities of clean energy. Hydrogen is emerging as a viable future fuel for addressing the move away from fossil fuels.
However, it is difficult to store and transport due to its low volumetric energy density and potential large vaporization losses.
Ammonia is significantly better suited than hydrogen for this purpose since it can be stored in liquid form at moderate pressures and temperatures.
As a carbon-neutral renewable energy carrier, ‘green’ ammonia is produced from hydrogen, via the electrolysis of water, and nitrogen from the air. The significant emission reduction impact will reflect this green approach when the energy is consumed.
Reconvert ammonia to hydrogen
Green ammonia acts as a liquid battery with a high energy density compared to alternative solutions for the storage and transport of renewable power.
The infrastructure for the large-scale transport of ammonia at sea already exists via a fleet of gas tankers having ammonia on the cargo list.
This important project is a natural extension of the investments and efforts made by Wärtsilä to accelerate the use of decarbonized energy. Hydrogen will play a considerable role in future renewable fuel consumption, and there is a clear need for the development of Ammonia as a storage and transportation carrier for hydrogen. We are grateful to the Norwegian government for its support and funding, and we appreciate also the cooperation of Höegh LNG and our other partners in making this project possible, said Walter Reggente, VP of Wärtsilä Gas Solutions.
The project aims to develop a system to convert ammonia back to hydrogen, which will then be installed onboard a Höegh LNG vessel.
This will provide a floating receiving terminal capable of being relocated as needed, requiring minimal use of coastal land and a solution resulting in lower overall cost, improved safety, and competitive hydrogen prices.
As a world-leading provider of fast-track floating LNG terminals, we are well-positioned to support the transition to clean, carbon-free energy. New and innovative solutions will need to be developed and we look forward to working together to ensure we remain at the forefront of the energy transition, said Erik Nyheim, CEO and President of Höegh LNG.
