Abstract

Geotermalna energija iskorištavana je za rekreacijske svrhe tisućljećima, ali samo za proizvodnju električne energije nešto više od stoljeća. Iako je geotermalna energija jedinstvena među obnovljivim izvorima energije zbog svojih osnovnih mogućnosti i mogućnosti opskrbe toplinom iz obnovljivih izvora, njezino iskorištavanje i dalje znatno zaostaje za drugim obnovljivim izvorima. To se uglavnom može pripisatinesigurnostima u pogledu raspoloživosti resursa u slabo istraženim ležištima i financijskim izdacima u ranoj fazi istraživanja. Napredak u tehnikama karakterizacije ležišta počinje sužavati granice nesigurnosti istraživanja, kako poboljšanjem procjena geometrije i svojstava ležišta, tako i pružanjem procjena temperature na dubini prije bušenja. Napredak u tehnologijama bušenja i upravljanju potencijalno mogu znatno smanjiti početni kapital, dok se operativni troškovi dodatno smanjuju učinkovitijim upravljanjem ležištem i sve učinkovitijim sustavima za pretvorbu energije. Povećana svjesnost o blagodatima geotermalne energije, te sve veći tehnološki napredak mogu dovesti do toga da geotermalna energija postane glavna vrsta obnovljivih izvora.

Abstract (english)

Geothermal energy has been used for recreational purposes for millennia, but its exploitation for generating electricity started just over a century ago. Although geothermal energy is unique among renewable energy sources due to its basic capabilities and the ability to supply heat from renewable sources, its exploitation still significantly falls behind other renewable sources. This can be mainly attributed to uncertainty regarding the availability of resources in poorly explored deposits and financial expenditures at an early stage of exploration. Advances in reservoir characterization techniques are beginning to narrow the limits of exploration uncertainty, both by improving the estimates of reservoir geometry and properties and by providing temperature estimates at depth before drilling. Advances in drilling and management technologies can potentially significantly reduce start-up capital, while operating costs are further reduced by more efficient reservoir management and increasingly efficient energy conversion systems. Increased awareness of the benefits of geothermal energy along with technological advances can lead to geothermal energy becoming a major type of a renewable energy technology.
