The author Kay Dohnke looks back on many years as an editorial director editor in chief and author of books Today he lives and works near Hamburg as a freelance journalist His topics are focused on the sustainable transformation of energy mobility raw material usage and production technologies gas footprint than coal fired powerplants because drilling into the Earth may cause carbon dioxide and methane that s bound there to escape That s another challenge to be mastered by Quaise and other pioneers in this field Field tests to begin in 2024 To accomplish the move toward a new geother mal future from pure theory and research into the tough reality of field operations Quaise raised funding in the amount of 63 million U S dollars at the beginning of 2022 The U S Department of Energy is on board as well Any support is as wel come as it is necessary because gyroton drilling projects are very difficult technological undertak ings says Quaise s co founder Carlos Araque To his surprise he s also found support in the oil and gas industry These companies are starting to un derstand that they need to embrace the green en ergy transition he told MIT Technology Review A joint roadmap of the German Fraunhofer Soci eties and the Helmholtz Association also recom mends a broad alliance of the political business and academic communities for deep geothermal like in the case of driving hydrogen technologies That includes balancing the risks for private sec tor companies and local governments tackling the exploration of deep geothermal energy In addi tion capital investment grants for key technol ogies are necessary including drilling systems and pumps high temperature heat pumps and large scale heat accumulators Moreover large scale utilization of geothermal energy requires cross sector integration and broadly designed combined heat networks In spite of all challenges Quaise continues driv ing its idea initial demonstration drillings down to depths between 100 328 and 1 000 meters 3 280 feet are planned to start in 2024 Provid ed that they produce the expected success the conversion of the first power station to deep geo thermal energy is targeted for 2028 It remains to be seen whether that facility will be able to deliv er energy at market prices Hence the road toward using deep geothermal energy is still as long as it s deep Piping hot water There are few places on the planet where hot ground water can be accessed as easily as in Iceland No wonder the world s first geothermal powerplant for electricity and heat the Svartsengi Power Station pictured was established there 19 RENEWABLE ENERGIES
