“Largest of its kind” biomass carbon removal & storage project announced in Switzerland
The companies said the project is set to become the largest of its kind in the country to date, with 21,800 tonnes of CO₂ to be removed over five years.
CO2 Energie is planning to install a system that captures and liquefies CO₂ at a biogas plant close to Zurich.
This will involve the annual capture and subsequent conversion of ~4360 tonnes of CO₂ emissions directly at their point of origin.
This is the second carbon capture project for CO2 Energie. The first system installed is already capturing CO₂, which is supplied to the Swiss gas market and recycled, replacing fossil CO₂.
With this second system, the company said it is going a step further by producing negative emissions for the first time: after capture, the liquefied CO₂ is transported to a geological storage site in northern Europe by truck, train and ship, where it can be stored permanently.
South Pole's subsidiary Airfix plays a key role in ensuring that the CO₂ supply chain runs smoothly. Airfix specialises in the coordination and grouping of services for CO₂ transport and CO₂ storage.
Creating a market for CO₂ capture
In order to standardise the climate value of CO₂ capture, transport and storage, South Pole is developing a climate project in line with the specifications of the Swiss Federal Office for the Environment (FOEN).
An important milestone in the implementation of the project was recently reached: The Swiss Climate Cent Foundation will guarantee the purchase of CO₂ certificates from this project for an initial value of CHF 10 million (€10.4 million) until 2030.
"This project in negative emissions technologies (NETs) marks a first step for Airfix and South Pole in their vision of creating a market for negative emissions from biomass and scaling it using innovative climate financing," said South Pole in a press release.
"Thanks to its foothold in the biogas and energy market, CO2 Energie AG is a strong partner for advancing NET projects."
The complete capture and liquefaction system is expected to be operational by the end of 2025.
