Dej nyab, cov mines siv hluav taws xob tuaj yeem hloov pauv peb lub tsev li cas

LONDON - Qhov cuam tshuam ntawm Kev Hloov Kho Kev Lag Luam, uas muaj nws cov hauv paus hauv 18^th-century Britain, tau loj heev.

Tebchaws Askiv qhov kev nplua nuj ntawm cov thee - nrog rau qhov yooj yim uas nws tuaj yeem nkag mus tau - yog qhov tseem ceeb hauv qhov kev hloov pauv keeb kwm no, ua kom lub zog ntawm lub tshuab hluav taws xob uas pab tsav lub zej zog kev hloov pauv.

Tab sis tej yam tau hloov lawm. Tus naj npawb ntawm cov chaw ua haujlwm thee nyob ntawd tau poob qis, thiab lub Rau Hli dhau los, cov tub ceev xwm tshaj tawm Tebchaws Askiv yuav tsum tsis txhob siv cov thee los tsim hluav taws xob txij lub Kaum Hli 2024, ib xyoos ua ntej lub hom phiaj ntawm 2025.

Txawm hais tias feem ntau cov mines hauv UK tau kaw, lawv cov dab neeg ntau pua xyoo tsis tas yuav tsum dhau. Hauv Scotland, kev ua haujlwm tab tom pib saib yuav ua li cas cov dej uas muaj dej nyab qub, cov mines tsis siv neeg tuaj yeem siv los muab cov cua sov decarbonized rau cov tsev.    

Ua qhov kev tshawb fawb no yog ib qho chaw hu ua Glasgow Geoenergy Observatory, uas yog khiav los ntawm British Geological Survey. Ib lub kaum ob borehole tau raug laum, nrog rau feem ntau hauv Rutherglen, ib lub nroog sab qab teb ntawm Glasgow.

Raws li cov neeg nyob tom qab qhov project, Glasgow thiab Rutherglen tau nyob hauv qee qhov chaw ua haujlwm loj tshaj plaws hauv Scotland. Tom qab lawv kaw, cov dej nyab ntuj tau ntim lawv nrog dej ntawm li 12 degrees Celsius.

Mike Stephenson, uas yog mus txog rau tam sim no tus thawj coj ntawm tus kws tshawb fawb txog decarbonization ntawm British Geological Survey, hais rau CNBC tias txoj haujlwm yog hais txog "kev tshawb fawb txog cov cua sov hauv cov mines thiab tseem, rau qee qhov, txawm tias koj tuaj yeem khaws cov cua sov hauv cov mines qub. ”

Stephenson tau hais tias ntawm qhov chaw uas ua haujlwm, pab pawg yog "Kev sim nrog ... cov dej nrawm npaum li cas hauv cov mines no, dej sov npaum li cas, ... sai npaum li cas, yog tias koj tshem dej sov tawm, cov dej puas rov qab - yog li qhov sov sov rov qab los sai npaum li cas."

"Nws yog qhov chaw tshawb fawb, tsis yog ua qauv qhia," nws hais. Kev tshawb fawb tau ua "kom sim thiab nkag siab tias qhov txwv tsis pub muaj cua sov, qhov kub npaum li cas."

"Tag nrho cov khoom no yuav yog ib txheej ntawm kev tshawb pom thiab kev sib npaug thiab cov qauv," nws hais ntxiv. Nws hais tias qhov no yuav muab cov ntaub ntawv tseem ceeb rau ob lub tuam txhab thiab cov tub ceev xwm hauv nroog txaus siab rau lub tswv yim.

"Nws yuav pab lawv txiav txim siab seb yuav ua qhov twg, ze li cas koj xyaum lub qhov ua ke, qhov tob npaum li cas koj xyaum lawv, koj tsim lawv li cas kom nws ua tau zoo li sai tau."

Qhov project tau ua tiav hauv 12 lub hlis dhau los lossis ntau dua. Thaum lub caij ntuj sov xyoo 2021, nws tau tshaj tawm tias kev sim ntsuas tau ua tiav thiab cov qauv sau los ntawm 10 ntawm qhov chaw boreholes.

Alan MacDonald, tus kws tshawb fawb hydrogeologist nrog British Geological Survey, tau hais thaum lub sijhawm ntawd, "Cov ntaub ntawv tshiab tshaj tawm qhia tias cov boreholes ntawm Glasgow Observatory tau txuas nrog zoo rau cov dej nyab kuv ua haujlwm,"

Kuv cov dej ntawm 50 thiab 90 meters hauv Glasgow ntsuas ntawm 11 txog 13 degrees Celsius, nws hais ntxiv. Rau kev sib piv, qhov nruab nrab kub ntawm Scottish av hauv av yog 10 degrees, MacDonald tau hais.

Raws li Britain's Coal Authority, 25% ntawm UK cov vaj tsev nyob zaum ntawm coalfields. Raws li lub hauv paus ntawm cua sov, lub peev xwm ntawm cov av hauv av, dej nyab mines xws li cov uas tau tshawb fawb hauv Glasgow zoo li muaj ntau heev.

Hais txog nws tus kheej cov kev suav, Lub Tuam Txhab Coal hais tias "cov dej tsis tu ncua ntxiv nyob rau hauv cov mines no tuaj yeem yog cov peev txheej txaus los muab tag nrho cov kev xav tau cua sov rau thaj chaw coalfield." Nws kuj tseem tuaj yeem muaj cov ntawv thov hauv cov haujlwm xws li kev tsim khoom thiab horticulture.

"Cov dej hauv cov mines no yog cov pa roj carbon tsawg, cov khoom siv hluav taws xob ruaj khov, uas nyob rau hauv cov xwm txheej zoo tuaj yeem sib tw nrog cov nqi siv roj rau pej xeem thiab xa cov pa roj carbon ntau txog 75% piv rau cov cua sov," nws sau tseg.

Cov tsoomfwv tseem tab tom sim txav deb ntawm cov thee, tab sis nws tseem ua lub luag haujlwm tseem ceeb hauv ntau lub tebchaws. Raws li International Energy Agency, thee muab ib ncig ntawm ib feem peb ntawm kev tsim hluav taws xob thoob ntiaj teb.

Lub Kaum Ob Hlis Ntuj tas los, lub koom haum Paris-based hais tias cov hluav taws xob hluav taws xob hluav taws xob yog vim muaj kev kub ntxhov txhua lub sijhawm hauv xyoo 2021. Raws li kev tsim cov thee, IEA tau hais tias nws "kwv yees kom ncav cuag qhov siab tshaj plaws hauv 2022 thiab tom qab ntawd toj siab. thov flattens. "

Thaum nws tseem ceeb heev rau lub ntiaj teb kev lag luam thiab tseem yog qhov tseem ceeb ntawm hluav taws xob, thee muaj txiaj ntsig zoo rau ib puag ncig.

US Energy Information Administration teev ntau yam emissions los ntawm thee combustion. Cov no muaj xws li carbon dioxide, sulfur dioxide, particulates thiab nitrogen oxides.

Lwm qhov, Greenpeace tau piav qhia cov thee yog "qhov qias neeg tshaj plaws, feem ntau ua rau muaj kuab paug rau kev tsim hluav taws xob."

Nyob rau sab qaum teb sab hnub tuaj ntawm Askiv, Sab Qab Teb Tyneside Council tau ua haujlwm rau ib qhov project aiming repurpose ib feem ntawm cheeb tsam cov cuab yeej cuab tam mining.

Raws li pawg sab laj, £ 7.7 lab ($ 10.4 lab) Hebburn Minewater Project yuav "txiav lub zog hauv av los ntawm cov mines dej nyab uas tso tseg hauv Hebburn Colliery yav dhau los."

Lub hom phiaj yog txhawm rau muab cov cua sov rau ntau lub tsev uas pawg sab laj muaj los ntawm kev siv kuv cov dej los ntawm cov qub colliery, uas tau qhib thaum lig 18th.^th xyoo pua thiab kaw hauv xyoo 1932.

Qhov project yog nruab nrab ntawm qhov drilling ntawm ob qhov boreholes. Lub twj tso kua mis dej kub yuav tshem tawm cov dej hauv kuv lub tshav kub, tom qab ntawd nws yuav raug compressed mus rau qhov kub ntau dua. Tom qab funneled mus rau ib lub zog chaw, ib tug tshiab network ntawm cov kav dej yuav siv tau rau kev faib.

Pawg sablaj tab tom ua haujlwm ntawm qhov project, uas tau teem sijhawm kom tiav thaum Lub Rau Hli 2023, nrog rau Durham University thiab Coal Authority. Lub Kaum Hli Ntuj dhau los, nws tau tshaj tawm tias kev sim tau pom tias kuv cov dej kub tau sov dua li qhov pib xav.

Kev sim siv cov dej sov ntawm cov mines dej nyab tsis yog qhov tshwj xeeb rau UK Xyoo 2008, ib lub chaw piav qhia los ntawm European Commission ua thawj qhov chaw nres tsheb dej hauv ntiaj teb tau qhib hauv Netherlands. Ib txoj haujlwm zoo sib xws raws li kev siv mine dej los ua kom sov cov tsev hauv Asturias, sab qaum teb Spain, kuj tau tsim.

Rov qab mus rau South Tyneside tus kws sab laj Ernest Gibson, uas nws luv luv hais txog kev hloov pauv huab cua, tau hais rau CNBC txog kev lag luam kev sib raug zoo nrog thaj chaw thiab nws txoj kev cia siab rau yav tom ntej.

"Kev lag luam ntawm thaj chaw poob qis [raws li] cov mines thee kaw," Gibson, tus qub miner, tau hais.

Nws tau piav qhia tias qhov kev kaw ntawm kev sib tsoo cuam tshuam tsis yog tsuas yog kev lag luam mining xwb tab sis kuj tseem muaj lwm yam xws li steel thiab thauj kev lag luam, nrog rau kev ua haujlwm me me xws li cov khw hauv zos thiab "ragman," ib lo lus rau tus neeg yuav khoom, sau thiab muag khoom qub.

Gibson tau mus hais rau CNBC tias nws "zoo siab" ntawm qhov tseeb cov mines qub tau siv dua.

Nws tau hais tias, "Lub tsev cog khoom kaw tab sis ... lawv tau rov ua dua tshiab," nws hais, tom qab ntawd tawm suab ntau dua. "Nws zoo li lub neej - txhua yam hloov pauv, tsis muaj dab tsi nyob twj ywm. Thiab kuv xav tias nws yog qhov zoo tshaj plaws. "
