Abstract
Field scale reactive transport models of CO\(_2\) and H\(_2\)S mineral sequestration in basalts were developed with a focus on Reykjavik Energy’s ongoing CarbFix and SulFix sour gas re-injection tests at Hellisheidi geothermal power plant, SW-Iceland. Field data, such as drill cuttings and a calcite cap-rock overlying the high-temperature geothermal reservoir, suggest that mineral CO\(_2\) and H\(_2\)S sequestration already plays an important role within Hellisheidi geothermal system. The data indicate CO\(_2\) sequestration to be most intensive from 550–800-m depth below surface, while H\(_2\)S sequestration is most intensive below 800-m depth. Injecting and pr...
