Fibre-optic monitoring for high-temperature Carbon Capture, Utilization and Storage (CCUS) projects at geothermal energy sites
It is often assumed that geothermal energy provides a clean source of renewable energy without emissions of carbon dioxide (CO2) or other greenhouse gases. In fact, most geothermal energy plants emit CO2 and small amounts of other gases, typically up to 5% of by weight. Reinjection of produced CO2 b...
