Assessment of prospective resource base for EGS in Europe
A new paper titled "Assessing the prospective resource base for enhanced geothermal systems in Europe" has been published and is freely available to all.
In a recently published article in Geothermal Energy Science of the International Geothermal Association (IGA), the authors discuss the prospective resource base for enhanced geothermal energy systems in Iceland.
The research assesses different technological-economic scenarios for the future of enhanced/ engineered geothermal systems (EGS) in Europe in 2020, 2030 and 2050.
The abstract states that “In this study the resource base for EGS (enhanced geothermal systems) in Europe was quantified and economically constrained, applying a discounted cash-flow model to different techno-economic scenarios for future EGS in 2020, 2030, and 2050. Temperature is a critical parameter that controls the amount of thermal energy available in the subsurface. Therefore, the first step in assessing the European resource base for EGS is the construction of a subsurface temperature model of onshore Europe. Subsurface temperatures were computed to a depth of 10 km below ground level for a regular 3-D hexahedral grid with a horizontal resolution of 10 km and a vertical resolution of 250 m. Vertical conductive heat transport was considered as the main heat transfer mechanism. Surface temperature and basal heat flow were used as boundary conditions for the top and bottom of the model, respectively. If publicly available, the most recent and comprehensive regional temperature models, based on data from wells, were incorporated.”
