CNetSS
Carbon Network South Sweden (CNetSS) is a collaborative project led by Växjö Energi, with the goal of capturing, transporting, and storing carbon dioxide in southern Sweden.
CNetSS has a long-term goal of boosting the potential for both emission reductions and negative emissions. Eight other partners are part of the project: Copenhagen Malmö Port, E.ON, Höganäs AB, Kemira, Kraftringen, Stora Enso, Sysav, and Öresundskraft. Our ambition is to establish a sustainable and cost-efficient carbon infrastructure – transporting CO₂ from emission sources to permanent geological storage in the North Sea, about 3 km below the seabed.
By joining forces to create the right conditions for infrastructure and a value chain for CO₂ capture and storage, costs across the entire chain can be reduced. Several companies already have concrete timelines for carbon capture. Together, the potential is to capture and store more than 2 million tons of CO₂ every year.
Great potential for negative emissions
CNetSS was launched in September 2022. The project aligns closely with Industriklivet – the Swedish government’s long-term initiative to support the climate transition – and has therefore been granted financial support by the Swedish Energy Agency. In its decision, the agency highlighted that the project is seen as an important step toward realizing the value chain for bio-CCS (biogenic Carbon Capture and Storage). The potential for negative emissions is also expected to grow further as fossil fuels are phased out in favor of renewables.
Negative emissions are crucial for meeting climate targets, and Sweden has strong conditions for this thanks to large point sources of biogenic CO₂. Another key aspect is that conventional carbon capture technologies consume large amounts of electricity and heat. With the world-unique technology used in this project, we also aim to demonstrate that CO₂ can be captured with significantly lower energy consumption.
CNetSS creates synergies with the collaborative project CinfraCap, but it also brings completely new dynamics – involving different partners, more varied CO₂ volumes across the year, as well as local and regional logistics solutions and business models.
