廢棄煤礦的地熱能源研究獲得資助

達勒姆郡議會已經獲得了11萬英鎊的撥款,以研究利用彼得利附近的霍爾登的地下水自然產生的熱量的可行性。

一個想法是利用抽上來的溫度為20攝氏度的礦泉水來加熱溫室,以幫助糧食生產。

煤炭管理局在達勒姆郡不斷抽出廢棄的礦井,以阻止水位上升,並防止其污染地下水位較高的飲用水供應。

目前,被地熱能自然加熱的礦井水被儲存在池塘里,清洗掉鐵質沉積物後被抽到海里,但委員會正在考慮利用自然熱量。

地熱能用於食品生產並不是一個新的想法,在一些國家已經使用了幾十年,特別是在冰島,那裡的溫泉為溫室提供動力,可以全年種植。

議會發言人說,作為開發1500個家庭的Seaham花園村的一部分,已經在Dawdon建立了一個利用前煤礦的地熱的區域熱網。

威爾克斯先生說。"有一些奇妙的機會,可以探索利用低碳為企業供熱或在該地區種植糧食的可能性"。

"從長遠來看,我們可以利用礦泉水的熱量來幫助加熱我們的社區項目,這真是不可思議。"

達勒姆縣議會正在與東達勒姆信託基金、煤炭管理局、東達勒姆商業服務機構和霍爾登的社區代表合作,他們從東北地方企業合作組織、商業能源和工業戰略部以及淨零中心獲得了研究資金。


Durham County Council has secured a £110,000 grant to study the feasibility of using the naturally generated heat from underground water in Horden near Peterlee.

One idea is to use mine water pumped up at temperatures of 20C to heat greenhouses to aid food production.

The Coal Authority is constantly pumping out disused mines across County Durham to stop water levels rising and prevent it polluting drinking supplies found higher up the water table.

Currently the mine water, which has been naturally heated by geothermal energy, is stored in ponds, cleaned of iron deposits and pumped out to sea, but the council is considering utilising the natural heat.

Geothermal energy in food production is not a new idea and has been used for decades in some countries, notably in Iceland where hot springs power greenhouses for growing all year round.

A district heat network using geothermal heat from a former coal mine has already been created in Dawdon as part of the development of the 1,500 home Seaham Garden Village, a council spokeswoman said.

Mr Wilkes said: "There are some fantastic opportunities to explore the possibility of using low carbon to heat businesses or to grow food in the area."

"It's incredible to think that in the long run we can use heat from mine water to help heat our community projects."

Durham County Council is working with East Durham Trust, the Coal Authority, East Durham Business Services and community representatives in Horden having secured the funding for a study from the North East Local Enterprise Partnership, Department for Business Energy and Industrial Strategy and the Net Zero Hub.
