Zero-Emission Geothermal Power Generation: Experimental Study on Carbonate Mineralization through CO2-Andesitic Pyroclastic Rock Interaction at Oku-Aizu Geothermal Plant

Received: 27 November 2019;  Published: 12 February 2020;  doi: 10.21926/jept.2001002

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 [...]

Abstract

Most power plants produce electricity by converting a mechanical motion into alternating current (AC). Photovoltaic solar panels convert an electromagnetic flux of light into direct current (DC). In general, electric energy can be harvested from a flux in the environment or from a change of the environment itself. One can produce electricity from mechanical, chemical, thermal, electromagnetic (light), or another physical flux, or from a change of temperature, chemical composition, or a physical [...]
