SANDNES, Norway – Horisont Energi has applied for a license to establish the Polaris CO₂ storage facility offshore the coast of Finnmark, northern Norway.
Last Friday, the Petroleum and Energy Ministry announced the application process for a permit for storage of CO₂ offshore Finnmark.
Horisont’s goal, if successful, is to develop storage for CO₂ captured during large-scale production of clean ammonia at the planned Barents Blue plant in Hammerfest, named ‘Polaris.’
Last week, the company announced a co-operation agreement with Equinor and Vår Energi concerning the Barents Blue project. The Polaris license would likely cover the necessary storage capacity, including all potential expansions, while additional storage capacity would be offered to third parties in Norway and Europe.
The project would entail using natural gas to produce ammonia, an industrial gas used globally in the fertilizer and chemical sector. Ammonia is also said to be an efficient hydrogen carrier, and therefore a prospective fuel for decarbonization of parts of the maritime sector.
During the production process at the proposed plant, more than 99% of CO2 in the process gas would be captured and permanently stored in the offshore Polaris reservoir below the seabed off Finnmark. The reservoir may have a storage capacity of more than 100 MMt, around twice Norway’s annual greenhouse gas emissions.
Once operational, Horisont plans a production capacity of 3,000 t/d of ammonia, with the carbon captured and permanently stored in the reservoir.
