Carbfix, the company pioneer in sequestering CO2 underground as a rock, announced a new milestone regarding one of its carbon capture and storage projects in Iceland. Carbfix commenced construction on an upgraded carbon capture plant at Hellisheiði (Hellisheidarvirkjun) in Iceland, known as the Silverstone project.
The construction will expand the carbon capture capacity of the facility to take away around 85% of carbon dioxide emissions and almost all of hydrogen sulfide emissions from the Hellisheiði geothermal power plant, owned and operated by ON Power, a subsidiary of Reykjavík Energy. The upgraded capacity will start operating by 2025.

The geothermal power plant Hellisheidi is Iceland’s largest geothermal power station with a capacity of 200 megawatts in thermal power and 303 megawatts in electricity. It emits about 40,000 metric tons of CO2 per year. Currently, the carbon capture facility takes away around 30% of the CO2 emissions (corresponding to about 12,000 metric tons of CO2 annually) and 75% of hydrogen sulphide emissions from the plant.
The Silverstone project will position Hellisheiði as the world’s first near carbon-neutral geothermal power plant. It will cover 10% of Iceland’s 2030 carbon neutrality goals. Carbfix and ON Power have also received a grant of €3.9 million from the EU Innovation Fund for the project.
