La amandla we-geothermal Luhlobo lwamandla avuselelekayo aqhamuka ngaphakathi emhlabeni. Ngakho-ke kungamandla angakhishwa kunoma yiliphi iphuzu. Ngenxa yayo, izakhiwo eziningi zingahlinzekwa ngokushisa ebusika nokupholisa ehlobo nge ukufakwa kwe-geothermal. Njengoba izinga lokushisa lomhlabathi lihlala njalo, ebusika ukushisa okugcinwe enhlabathini engaphansi kuyasetshenziswa futhi kuthunyelwe esakhiweni kanti ehlobo ukushisa kwesakhiwo kuthunyelwa enhlabathini engaphansi. Konke lokhu kwenziwa ngenxa yepompo lokushisa okushisa phansi.
Isakhiwo esiseMnyangweni wakudala Wokuhlelwa Kwezindawo Ezisedolobheni, esifundeni saseChamartín (eMadrid), singesinye sezakhiwo ezakhiwe ngamandla amakhulu ngoba sine indawo enkulu yokuphehla ugesi ngamandla. Kunama-cooperatives angaphezu kwama-200 eMadrid azovula izakhiwo ngalokhu kusebenza kahle kwamandla. I- amandla kagesi akhiqizwa yisakhiwo angama-540 Kw, edlula esinye isakhiwo enhlokodolobha esikhiqize i-430 kW futhi ngamandla e-geothermal.
Ukuze kwakhiwe lesi sikhungo, kwenziwe izimbobo ezingama-70 egumbini elingaphansi kwalesi sakhiwo ngokujula okungafika kumamitha ayi-130. U-Alberto Rubini, umakhi walezi zakhiwo, uthi kulawa kujulile kunesifunda samanzi esihlala sizinzile ngama-degree angu-18 unyaka wonke. Banempompo yokushisa etholakala engxenyeni engezansi yesakhiwo ekhiqiza ngayo amanzi ashisayo ebusika futhi epholisa ngayo ehlobo.
Izinzuzo zalolu hlobo lokusungula amandla yilezi:
- Kuyinto mahhala ngokukhishwa kwe-CO2 (kuze kufike ezingeni lokuthi ingakhipha kuze kube ku-19 ngaphansi kwe-CO2 ukwedlula impahla ejwayelekile).
- Amandla asetshenzisiwe ngu ivuseleleke.
- Iyakwazi ukuba ngesinye sezakhiwo ezisimeme kakhulu ngenxa yezinye izinyathelo ezithathiwe njengama-facade angena umoya, ukuma kwezindlu kabili, izinto zokwakha ezinamandla amakhulu okuvikela, indawo yegaraji eneshaja yayo yezimoto zikagesi, njll.
- Ukonga okukhulu kwezomnotho kuqhathaniswa nezakhiwo ezijwayelekile (ukusetshenziswa kwamandla kwe 15 Kw / m2 ngaphambi kwe 248Kw / m2 ezivamile).
Ngakho-ke, lolu hlobo lwesakhiwo luyisibonelo samandla okufanele silandelwe emakhaya azayo kusukela iSpain izibophezele ekwehliseni ukungcola okuvela emikhakheni ehlukahlukene kuze kufike ku-30% ngo-2030 maqondana namazinga akhishwe ngonyaka we-2005 maqondana neSivumelwano Sezulu saseParis.
