CCS at Hellisheidi Geothermal Power Plant

The CarbFix project started at the Hellisheidi Geothermal Power Plant in 2007. Its goal is to reduce carbon dioxide emissions from the power plant by reinjecting it, dissolved in water, into the basaltic bedrock in the vicinity and sequestering it there in mineral form. Some 3,900 tons of carbon dioxide were channelled down into the bedrock in 2015, i.e. over 10% of the carbon dioxide annually emitted by the plant. Results indicate the carbon dioxide to being being swiftly and permanently sequestered in the basaltic bedrock. The results of the CarbFix project, as well as its methodology and technical equipment have been used directly for removing the hydrogen sulphide emissions from the Hellisheidi Geothermal Power Plant.
