Storing Captured Carbon Dioxide from Filbornaverket.

After its journey from Filbornaverket, the liquefied CO₂ reaches its final destination: permanent storage deep beneath the seabed. This crucial step ensures that carbon emissions are safely removed from the atmosphere, supporting Helsingborg’s climate goals and Öresundskraft’s commitment to sustainable energy solutions.

At the storage site, both fossil and biogenic CO₂ are injected at least 1200 meters below the seabed. Fossil CO₂ comes from materials like plastics, while biogenic CO₂ is released from organic waste. Storing biogenic CO₂ actively removes carbon from the natural cycle, resulting in real negative emissions, a net reduction of atmospheric CO₂.

The CO₂ is pumped into porous sandstone formations sealed by thick layers of rock. Over time, it mineralizes, gradually turning into stone, making the storage even more secure.

Future Opportunities for Local Storage
Today, the captured CO₂ is transported to storage sites in Denmark or Norway. We are committed to maintaining a sustainable and efficient transport chain throughout the entire process, minimizing emissions and maximizing efficiency. However, if Swedish storage solutions become available, such as those proposed off Gotland and Trelleborg, the logistics could be greatly optimized. Shorter transport distances would not only reduce costs and emissions but also streamline the entire operation.

Öresundskraft is prepared to adapt as infrastructure evolves, ensuring that our carbon storage remains both sustainable and aligned with Helsingborg’s climate ambitions.
