The CNetSS project, led by Växjö Energi, has chosen the main alternative for interim storage of carbon dioxide before transport to final depot: Copenhagen Malmö Port's (CMP) Norra Hamnen.

"Malmö is the most efficient and flexible alternative, both for receiving large amounts of carbon dioxide from various locations in southern Sweden and for loading and transporting it to the geological final storage," said Ghazale Nilsson, Project Manager for CNetSS at Växjö Energi.

She furthered, "We are now continuing our dialogue with various actors in the transport chain. Interim storage requires a great deal of work in terms of permits, risk analysis, coordination of logistics and infrastructure expansion, such as new roads and train tracks. There are many factors to consider."

Sune Norup Christensen, CCO, CMP, also commented, "CMP sees the establishment of an intermediate storage facility for CO2 at the port area in Malmö as a natural extension of CMP's sustainability strategy and as an essential track towards a green transition. With Malmö's location, the opportunity to allocate land, and the close local collaboration among emitters, infrastructure partners, CMP, and the city of Malmö, we also see CCS [carbon capture & storage] as a potential positive commercial opportunity. We are dedicated to realising the ambition in an 'open access' hub for CO2."

The CNetSS project, which the Swedish Energy Agency awarded SEK2.5m, gathers ten actors who work on establishing a transport, liquefaction and storage infrastructure in Southern Sweden, with the potential to capture two million tonnes of CO2 per year. Works in 2023 centred around a feasibility study in which various alternatives for carbon dioxide storage were analysed.

Apart from CMP and Växjö Energi, E.ON, Höganäs, Kemira, Kraftringen, Nordion Energi, Stora Enso, Sysav, and Öresundskraft take part in the autumn 2022-launched initiative.

Since mid-2022, Växjö Energi has been testing new CCS technology developed by the University of Lund's Faculty of Engineering, which is said to require noticeably less energy than previous solutions. The new method will capture biogenic carbon, resulting in negative emissions. Växjö Energi intends to capture some 200kt in the near future.
