Airfix is proud to announce a pivotal collaboration between CO2 Energie AG, a key partner in carbon capture and storage innovation, and INEOS, operator of Project Greensand Future, a cutting-edge initiative focused on CO₂ storage in the Danish North Sea. This agreement, facilitated by Airfix, marks a significant milestone in demonstrating the feasibility of European CO₂ transport and permanent storage.
The Swiss-based CO2 Energie project, led by RegionalWerke AG Baden and Recycling Energie AG, integrates biomethane production with state-of-the-art BECCS (bioenergy with carbon capture and storage) technology. It will capture and transport over 4,250 tonnes of biogenic CO₂ annually to the Greensand site in the North Sea, demonstrating the feasibility of cross-border CO₂ transport and storage, with operations set to start in Q2 2026. This achievement will establish it as the first Swiss commercial project to store CO₂ internationally and the only non-Danish project to secure CO2 storage in the country.
This collaboration builds on over two years of Airfix’s engagement with CO2 Energie and INEOS, which has also led to the Climate Cent Foundation guaranteeing the purchase of the first CHF 10 million worth of credits from the project. Together with South Pole, Airfix has advanced the project’s carbon asset development, sales strategies, partnerships and the broader project value chain, culminating in the project reaching a financial investment decision (FID) in 2024.
A European first in CO₂ storage
Greensand Future announced its own FID at the end of 2024, paving the way to launch Europe’s first full-scale CO₂ storage facility. This facility will begin operations in the INEOS-operated Nini West reservoir for permanent storage 1,800 meters beneath the seabed. INEOS is leading the project, together with partners Harbour Energy and Nordsøfonden.
Driving innovation and climate solutions
This agreement represents a critical milestone for Switzerland’s climate strategy, contributing to the binding net-zero target established by the Climate and Innovation Act (KlG), which entered into force on 1 January 2025. It also demonstrates a replicable model of combining BECCS technology with private sector investment and financial support, underscoring the role of international collaboration in achieving global net-zero targets.
Airfix extends gratitude to the Migros Pioneer Fund for their impactful funding and support, the EU’s Clean Energy Transition Partnership (CETP) for their support on the Airfix-led Carbon Rhine Route project, as well as Carbon Impact and our other partners whose dedication has driven this achievement.
As the world accelerates its climate action efforts, Airfix and its partners remain at the forefront of delivering practical, scalable solutions for carbon removal and storage. This agreement exemplifies how innovation, cross-border collaboration and early financial backing can create a sustainable pathway to achieving negative emissions globally.
