The website ThinkGeoenergy reported in February that preparations were ongoing for drilling a geothermal well in the south of Poland, with a potential terminal depth of 7 km. Reaching this…

Pumped geothermal power projects – a global overview

Elliot Yearsley

April 26, 2023

Pumped-well geothermal projects utilise the moderate temperature range of geothermal fluids between 100-190 C. Below this temperature, geothermal fluids are generally used for direct heating and above this the fluids…
