Towards Cleaner Geothermal Energy Utilization: Capturing And Sequestering Co2 And H2S Emissions From Geothermal Power Plants
Field-scale reactive transport models of CO2 and H2S mineral sequestration are in development, with a focus on Reykjavík Energy’s ongoing gas reinjection tests at Hellisheidi geothermal power plant. A new thermodynamic dataset describing the minerals of interest was developed as a part of this study...
