Zero-Emission Geothermal Power Generation: Experimental Study on Carbonate Mineralization through CO2-Andesitic Pyroclastic Rock Interaction at Oku-Aizu Geothermal Plant
Abstract
In order to achieve advancement in zero-emission geothermal power generation for fixing the CO2 in the geothermal fluids to the carbonate minerals after binary power generation and reinjection of the fluid into the reservoir, batch-type experiments and geochemical simulations of CO2-andesitic pyroclastic rock interaction (tuff from Oku-Aizu geothermal area) were performed at 150 °C with and without CO2 gas for 15 da [...]
