Project Greensand: INEOS and Öresundskraft to store 210,000 tonnes of CO2 per year in Denmark

Öresundskraft and INEOS on behalf of Project Greensand will jointly investigate the opportunity to store up to 210,000 tonnes of CO₂ annually from Sweden in Denmark. The captured carbon dioxide is planned for safe and permanent storage in Greensand storage facility located in the Danish part of the North Sea, with the first volumes expected to be stored from 2028.  

“This agreement with INEOS marks an important milestone for us,” said Stefan Håkansson, CEO of Öresundskraft. “We are at the forefront among our European industry peers when developing a sustainable and fully integrated CCS solution for energy recovery from waste. Our project has been awarded €54 million from the EU Innovation Fund and is one of Sweden’s first CCS initiatives. Our goal is to offer climate-neutral district heating and achieve negative emissions. Connecting Swedish carbon capture with Danish storage infrastructure highlights the importance of international cooperation in reaching climate goals. We are proud to be working with INEOS on this.” 

INEOS, through the Project Greensand consortium with partners Harbour Energy and Nordsøfonden, is leading the development of one of Europe’s most advanced CO₂ storage sites. The latest development will play a key role in receiving CO₂ from various European countries, including Sweden, for safe injection into offshore geological formations in Greensand. 

“The agreement with Öresundskraft marks the beginning of the next phase of Greensand—expanding the capacity to store CO₂ also from other EU member states,” said Mads Gade, CEO INEOS Energy Europe. “This is a significant step toward building a truly European CCS infrastructure that enables emissions reductions across borders.”  

This milestone follows a series of major developments in the Greensand project. In December 2024, INEOS and its partners Harbour Energy and Nordsøfonden made the Final Investment Decision (FID) to move ahead with full-scale CO₂ storage operations in the Nini Field. 

With the plan to initiate safe and permanent CO₂ storage in the Nini Field by late 2025/early 2026, Greensand is expected to become the EU’s first operational CO₂ storage facility aimed at mitigating climate change. This investment decision has paved the way for expected investments exceeding 1 billion DKK across the Greensand CCS value chain to scale up storage capacity. 

The Greater Copenhagen region holds significant potential for CCS due to its industrial base, infrastructure, and geographic proximity between Sweden and Denmark. This initiative exemplifies the commitment of Swedish and Danish stakeholders to take action and collaborate on climate solutions.
