Overview of techno-economic issues of enhanced geothermal systems implementation and integration

Nowadays, besides the conventional electricity generation, it is necessary to get new renewable sources which would be economically and ecologically profitable in the long-term. Along with wind and solar energy, tides, waves etc. it is worth noting that geothermal energy could be in use as well, especially when enhanced geothermal systems are used. Enhanced geothermal systems are artificially made reservoirs while injecting a fluid to make fractures and energy extraction. Some techno-economic issues arise when these enhanced systems are implemented at the particular site (technical, economic, environmental, legal and social impact) and integrated into the heat and electricity grid. This paper gives a short overview of these issues that should be accounted for in the long-term techno-economic modelling. This overview is the first step, necessary for the implementation of specific parameters that will be used later for in-depth techno-economic analysis of enhanced geothermal systems long-term performance.
