Enabling a complete and sustainable value chain for carbon capture-, transport and storage
Errai
The carbon market is the new emerging trillion dollar-market. To develop a commercial value chain of CCS is essential to the decarbonization of European industry.

The interest in carbon dioxide storage in Europe is substantial. Together with our project partner, Neptune Energy, Horisont Energi are developing a land-based carbon dioxide-terminal in Norway, subsea pipeline, and a seabed liquid carbon dioxide distribution and injection system connected to the offshore underground storage.
The terminal is designed to be capable of receiving carbon dioxide from both domestic and European industry, including carbon dioxide from the planned carbon dioxide-terminal in the Port of Rotterdam. E.ON, the European energy giant, has committed to store 1 million tonnes carbon dioxide annually in Errai. This is a great example of the European commitment and demand for carbon storage.
Errai reservoir evaluation studies indicate sufficient capacity to inject 4-8 million tons of carbon dioxide annually, over 25 years.
The emissions from passenger cars in Norway was 4,6 million tons in 2021. The Errai storage capacity will in other words potentially store 10 % of Norway’s emissions in total.
Errai will develop a land-based terminal for intermediate storage of carbon dioxide at Haugaland Næringspark, port of Gismarvik, before it’s transported in pipes and permanently stored in the offshore reservoir. Norway will get its second land-based carbon dioxide-terminal with Errai.
The CCS industry explained
What does CCS stand for? Why is it defined as one of the key measures by the IPCC (UN’s intergovernmental panel on climate change) to prevent and reverse climate change? How does the technology work, and why is Norwegian industry key to develop the CCS market?
We know it’s a lot to take in. The most important thing to remember about CCS is that it is crucial in reducing emissions in the short run, and in the long run enabling negative emissions.
Working together with an established and experienced company on the Norwegian continental shelf, we are paving the way for a commercialized CCS industry in Norway.
Neptune Energy is committed to the energy transition and the decarbonization of the oil and gas industry. Their vision is to be the leading independent E&P company by meeting society’s changing energy needs, focusing their experience on the CCS industry, amongst other areas.
Together we will deliver a commercial value chain for third party storage. With their experience and competence as offshore operator on Errai, Horisont Energi will be a key distributor of carbon storage facilities in Norway.
Establishing this industry in Norway is important to decarbonize both Norwegian and European industry. CCS is essential to reduce emissions drastically in the short run, but also in the long run for hard-to-abate industries.
