Abstract

The decarbonisation of power and heat production is recently one of the major challenges in the Energy sector. Among other technologies, deep geothermal energy is an interesting option, because source temperature, plant capacity, low environmental footprint and high availability allow the application in district heating grids. The majority of geothermal reservoirs contains a certain amount of non-condensable gases dominated by CO2. With respect to corrosion and precipitation effects as well as environmental friendliness and economic optimisation, the handling of these gases is challenging.
