World experience use of geothermal energy and prospects of its development in Ukraine

Abstract

We have analyzed the major activities carried out for geothermal electricity generation since WGC2010.New data has been taken from WGC2015 Country Update reports, private communications from IGA members and Affiliated Organizations, and we would like to acknowledge all IGA friends for their valuable help. Other updates have been collected from websites of private and public organizations involved in geothermal development. Plants under construction, which are expected to be commissioned in 2015, are included in the installed capacity. An increase of about 1,7 GW in the five year term 2010-2015 has been achieved (about 16%), following the rough standard linear trend of approximately 350 MW/year, with an evident increment of the average value of about 200 MW/year in the precedent

Впровадження Інноваційних Технологій У Системи Теплопостачання Військових Містечок Для Підвищення Їх Ефективності Та Надійності

“…Прорахунок встановлення геотермальної системи теплопостачання військового містечка передбачає збалансоване врахування всіх вищезазначених параметрів для забезпечення ефективності та економічності системи (Dolinskyi, Obodovych, 2016).…”

An assessment of technical and economic feasibility to install geothermal well systems across Ukraine

“…The application of geothermal heat supply systems is not only saving fossil fuels but also contributing to the solution of numerous environmental problems, especially reducing greenhouse gas emissions in industrial megacities (Hashida et al 2000;Mhitaryan and Machulin 2006;Dolinskyi and Obodovych 2016;Bayer et al 2016). Owing to renewability, the use of geothermal plants facilitates keeping the overall energy balance of the country (Kong et al 2014;Reinsch et al 2016).…”

“…The recent studies (Dolinskyi and Obodovych 2016;Moya et al 2018) made quite general estimations for wide intervals of depth without paying due attention to hydrogeological conditions, water cooling during operation; these studies did not use modern economic criteria. At the same time, nowadays GWS installation for long-term operation requires significant capital investments usually covered by different sources and credits; thus, the investment return for potential geothermal sites should be properly justified right at the design stage by modern economic indicators like the net present value (NPV).…”
