I-Iceland imboza umthombo ojulile wokushisa komhlaba osenhliziyweni yentaba-mlilo

Islandia

I-Iceland imba i- umthombo ojulile wokushisa komhlaba emhlabeni enhliziyweni yentaba-mlilo enokujula kwamakhilomitha ama-5 ukusizakala ngamandla ayo avuselelekayo.

Futhi ukuthi ingcindezi eyedlulele nokushisa okukhona kulawo madamu kungathola u-30 kuya ku-50 MW kagesi emthonjeni owodwa wokushisa komhlaba. I-Iceland yiyona umholi womhlaba ekusetshenzisweni kwamandla we-geothermal futhi ikhiqiza cishe amaphesenti angama-26 kagesi wayo emithonjeni ye-geothermal.

Umthamo wokukhiqiza ofakiwe we izitshalo zamandla aphuma ngaphansi komhlaba bekuyi esewonke ama-MW angu-665 ngonyaka wezi-2013 futhi ukukhiqizwa kwakuyi-5.245 GWh.

Umthombo ojwayelekile wamakhilomitha ayi-2,5 we-geothermal emikhakheni yase-Iceland amandla alingana no-5 MW. Ososayensi balindele a ukukhushulwa ngamashumi emandleni agqamile omthombo lapho kubhola ngokujule emgqeni womhlaba. Ekujuleni kwamakhilomitha ama-5, ingcindezi eyedlulele nokushisa okungaphezu kuka-500 degrees Celsius kuzodala "intuthu ebucayi" ezokwandisa kakhulu ukusebenza kahle kukaphephela.

Kuqhutshwa ibhizinisi elihlanganyelwe yiStatoil ne-Iceland Deep Drilling Project (IDDP), umthombo oshisa kakhulu emhlabeni oshisa kakhulu emhlabeni. enhlonhlweni yaseReykjanes, lapho kwaqhuma khona intaba-mlilo eminyakeni engu-700 edlule.

Un umzamo ofanayo eminyakeni eyisithupha edlule yaphela ngenhlekelele, ngensimbi yokubhola ethinta i-magma ekujuleni kwamakhilomitha ayi-2,1, kuqeda intambo yokubhola. U-gegege margeirsson, isikhulu esiphezulu sephrojekthi yabazali u-HS Orka, uthe:

Akunasiqinisekiso sokuthi izinto zihamba kahle, ekujuleni okunjalo yonke into ingaphenduka inhlekelele ngemizuzwana nje. Konke lokhu kungaba nokuphela okungalindelekile, ngoba ngasizathu simbe akukwazi ukubholwa kujule. Asilindelanga ukuthinta i-magma, kepha sizobe sibhola edwaleni elifudumele. Futhi ngedwala elifudumele, sisho ama-degree angama-400 kuye kwangama-500 Celsius.

Eminyakeni engu-7 ezayo izinhlelo ze-IDDP yilezi drill futhi uvivinye uchungechunge lwemithombo ezongena ezindaweni ezibucayi okukholelwa ukuthi zikhona ngaphansi kwezinkambu ezintathu esezivele zisetshenzisiwe e-Iceland.
