Havstjerne Carbon Storage Project

Founded by the EU

The STARFISH Project

The STARFISH (Sequestration Technology and Reservoir: Floating Injection and Storage in Havstjerne) project, will provide a first-of-its-kind, large-scale solution for CO2 sequestration using shared, flexible offshore infrastructure. In 2025, the project was awarded a €225 million grant from the EU Innovation Fund, payable depending on meeting certain conditions throughout the project lifetime after final investment decision.

The project focuses on an open-access CO2 storage concept that allows captured emissions from multiple sources to be safely stored in the Havstjerne reservoir

In 2023, the project partners were awarded an exploration license for the reservoir, and Phase 1 of the project is expected to enable the storage of 42.75 million tonnes of CO2-equivalent (CO2-eq) over the first 10 years. This effort is projected to avoid 42 million tonnes of CO2-eq emissions, with a relative greenhouse gas (GHG) avoidance potential of 98%.

STARFISH is the first offshore CO₂ storage project designed to transport liquid CO₂ via purpose-built ships directly to an offshore reservoir. This approach allows for a streamlined, cost-efficient process. The project will feature a specially designed injection unit capable of receiving large volumes of liquid CO₂ from transport vessels for secure and permanent storage. The initiative aligns with the European Commission’s goal of achieving 50 million tonnes per annum (Mtpa) of storage capacity by 2030. The STARFISH project represents a major step in creating a scalable and reliable storage solution that can accommodate existing and future CO₂ capture projects across Europe.
