Geothermal zog tuaj yeem hloov txoj kev lithium los ntawm

Sab qab teb sab hnub poob ntawm England yog nto moo rau nws cov ntug hiav txwv dej, cov ntug hiav txwv dej thiab cov nqaij nruab deg tshiab. Yog tias txhua yam mus rau txoj kev npaj, lwm txoj hlua tuaj yeem muab ntxiv rau thaj tsam hneev nti hauv ob peb xyoos tom ntej no: lithium extraction.

Hauv lub nroog Cornwall, kev siv zog tab tom pib coj mus rau hauv thaj chaw cov peev txheej ntuj thiab tsim kom muaj kev lag luam uas tuaj yeem, ib hnub, tsim hluav taws xob tauj dua tshiab thiab tsim kom muaj cov lithium hauv zos.

Nrog rau kev siv hauv xov tooj ntawm tes, khoos phis tawj, ntsiav tshuaj thiab lwm yam khoom siv sib txuas nrog lub neej niaj hnub, lithium tseem ceeb heev rau lub tsheb hluav taws xob thiab roj teeb cia, ob lub thev naus laus zis nrog lub luag haujlwm tseem ceeb hauv lub ntiaj teb hloov mus rau qhov qis thiab xoom emission yav tom ntej. .

Piv txwv ntawm yuav ua li cas qhov kev lag luam no tuaj yeem vam meej nyob rau ob peb xyoos tom ntej no suav nrog Geothermal Engineering Ltd, lub tuam txhab nyob ze ntawm Cornish lub nroog Redruth tshwj xeeb hauv kev txhim kho thiab kev ua haujlwm ntawm cov haujlwm hauv av.

Nrog rau nws txoj kev npaj ua haujlwm rov ua dua tshiab, GEL tseem ua haujlwm rau kev sim ua haujlwm nyob ib puag ncig ntawm kev rho tawm lithium los ntawm cov dej kub hauv dej. Nws yog kev koom tes nrog lwm lub tuam txhab, Cornish Lithium, ntawm kev sib koom ua lag luam dubbed GeoCubed.

"Lub hom phiaj yog ua kom pom tias lithium hydroxide, ib feem tseem ceeb ntawm lithium-ion roj teeb uas siv hauv tsheb hluav taws xob, tuaj yeem tsim hauv Cornwall los ntawm qhov tshwm sim hauv dej hiav txwv nrog cov pa roj carbon monoxide, "GEL hais.

Qhov project hauv Cornwall yog tsom rau kev rho tawm ncaj qha lithium, lossis DLE. Raws li US Department of Energy lub National Renewable Energy Laboratory, cov thev naus laus zis tom qab DLE " tuaj yeem muab faib ua peb pawg tseem ceeb: adsorption siv cov khoom ntxeem tau uas ua kom muaj lithium bonding, ion pauv, thiab hnyav rho tawm."

Thaum muaj kev zoo siab txog nws lub peev xwm, NREL ceeb toom nws "tseem yog txoj haujlwm nyuaj" txhawm rau ntsuas cov txheej txheem saum toj no rau qhov nws hu ua "muaj peev xwm ua tiav."

"Piv txwv li, kev tsim cov khoom siv sib txuas nrog cov lithium nkaus xwb yog ib qho kev sib tw loj hauv cov dej kub hauv av uas muaj ntau cov minerals thiab hlau," nws hais.

Cov phiaj xwm xws li ib qho hauv Cornwall tuaj rau lub sijhawm thaum muaj kev txhawj xeeb txog kev ruaj khov thiab ESG tab tom txhim kho. Kev ruaj ntseg ntawm cov khoom siv thoob ntiaj teb yog lwm qhov teeb meem, tshwj xeeb tshaj yog thaum feem coob ntawm cov lithium ntau lawm tam sim no tau tswj hwm los ntawm cov teb chaws suav nrog Chile, Tuam Tshoj, Australia thiab Argentina.

Tawm tsam qhov keeb kwm yav dhau no, kev lag luam tsis tshua muaj zog, ntau hauv zos thiab yooj yim txoj hauv kev ntawm kev nrhiav cov lithium tuaj yeem yog qhov tseem ceeb heev mus rau yav tom ntej.

Kev lag luam loj thiab cov tuam txhab tsheb tseem tab tom tso tawm cov phiaj xwm kom nce cov tsheb fais fab ntawm peb txoj kev. Nyob rau tib lub sijhawm, kev thawb kom nthuav dav lub zog tauj dua tshiab tau qhia tias tsis muaj kev cia siab.

Julia Poliscanova yog tus thawj coj loj rau e-mobility ntawm Thauj & Ib puag ncig, pawg phiaj xwm hauv nroog Brussels. Hais lus rau CNBC, nws tau piav txog lithium yog "irreplaceable rau tag nrho peb cov kev hloov ntsuab."

Thaum nws los txog rau kev lag luam ruaj khov ntawm lithium thiab lwm yam khoom siv, Poliscanova tau hais tias, "nruab nrab mus rau lub sijhawm ntev, nws yog qhov tseeb tias feem coob ntawm nws yuav tsum yog los ntawm cov qauv kev lag luam ncig, tshwj xeeb tshaj yog rov ua dua tshiab."

Nws tau sau tseg tias yuav muaj "kev loj hlob thiab kev xav tau tiag tiag" li cas rau ob peb xyoos tom ntej no. Qhov no yuav xav tau, nyob rau hauv luv luv mus rau nruab nrab lub sij hawm, tshiab extraction txheej txheem.

Kev nthuav dav ntawm nws lub ntsiab lus, Poliscanova tau hais tias feem ntau ntawm lithium uas yuav siv rau xyoo 2030 tseem tsis tau muab rho tawm.

Nws tau hais tias "Qhov ntawd yog qhov chaw lithium los ntawm geothermal lithium, vim hais tias cov lithium tshiab, cov peev txheej tshiab uas peb xav tau, nws yuav tsum tau khawb kom ruaj khov thiab yuav tsum muaj kev cuam tshuam qis tshaj plaws rau ib puag ncig thiab peb cov zej zog."

GeoCubed's £ 4 lab ($ 5.46 lab) pilot cog yuav tsom mus rau ntau yam ntawm lithium extraction technologies ncaj qha. Lub hom phiaj tag nrho yog thaum kawg tsim kev lag luam cog ntawm GEL's United Downs Deep Geothermal Power Project.

Hauv kev xam phaj nrog CNBC, Ryan Law, GEL tus tsim thiab tus thawj coj saib xyuas, tau piav qhia txog lub sijhawm uas nws txoj kev lag luam tab tom nrhiav kom tau txais txiaj ntsig. Hauv qab nws qhov chaw, Cornwall yog lub tsev rau ntau lub pob zeb granite uas nyob rau hauv lem muaj cov ntsiab lus lithium siab, Txoj Cai piav qhia.

"Kev sib xyaw ntawm cov pob zeb granite yog nplua nuj nyob rau hauv lithium thiab dej kub - dej kub tuaj yeem nqus tau lithium ntau dua - txhais tau tias cov dej uas peb coj mus rau saum npoo ntawm United Downs los tsav peb lub zog cog muaj cov ntsiab lus lithium siab heev," nws hais. .

"Cov kauj ruam tom ntej yog: peb yuav ua li cas kom nws tawm?" Law mus hais ntxiv. "Thiab qhov ntawd yog qhov peb tau saib ua ke nrog ntau tus neeg koom tes."

Hloov sijhawm

GEL yog ib qho ntawm ntau lub tuam txhab nrhiav kev tsim cov chaw tsom mus rau kev rho tawm cov lithium ncaj qha. Nrog rau GeoCubed, Cornish Lithium kuj tseem ua haujlwm rau ntau qhov haujlwm.

Lwm qhov, thaum lub Plaub Hlis 2021, Australia-daim ntawv teev npe Vulcan Energy Resources tau hais tias nws qhov kev txiav txim siab ncaj qha lithium extraction cog cog, nyob hauv Tebchaws Yelemees Upper Rhine Valley, tau pib ua haujlwm.

Hauv Teb Chaws Asmeskas thaum Lub Kaum Ib Hlis, ib lub tuam txhab hu ua Controlled Thermal Resources tshaj tawm tias nws txoj haujlwm drilling ntawm Hell's Kitchen Lithium thiab Power project hauv California tau pib.

Thaum lub sijhawm, CEO Rod Colwell tau hais tias lub tuam txhab tau "rau lub sijhawm xa cov phiaj xwm thawj 50MW ntawm lub zog txuas ntxiv dua tshiab nyob rau xyoo 2023 thiab kwv yees li 20,000 tonnes ntawm lithium hydroxide hauv 2024."

Qhov project Hell's Kitchen yog qhov nyiam los ntawm qee tus neeg ua si loj. Lub caij ntuj sov dhau los, General Motors tau hais tias nws tau "pom zoo los tsim kev lag luam tawm tswv yim thiab kev sib koom tes ua lag luam nrog Cov Khoom Siv Hluav Taws Xob Hluav Taws Xob kom ruaj ntseg lithium hauv zos thiab tus nqi qis."

"Raws li thawj tus neeg ua lag luam, GM yuav muaj thawj txoj cai ntawm lithium tsim los ntawm thawj theem ntawm Hell's Kitchen project, suav nrog kev xaiv rau kev sib raug zoo ntau xyoo," tus tsim tsheb tom qab ntxiv.

Cov kev txhim kho saum toj no yog nyob rau ntau theem ntawm kev nce qib, tab sis yog tias lawv muaj peev xwm tsim tau ntawm qhov ntsuas, nws tuaj yeem ua rau muaj kev hloov pauv hauv hiav txwv ntawm txoj kev lithium tau sau.

Raws li NREL, feem ntau ntawm lithium yog los ntawm "qhib qhov mines lossis lithium-muaj cov dej ntsev hauv qab ntsev tiaj tus."

Nws piav qhia txog qhov kawg uas suav nrog cov dej ntsev uas muaj lithium tau "tso mus rau hauv cov phiab loj uas nws evaporates hauv qab hnub."

Cov kev cuam tshuam ib puag ncig ntawm cov txheej txheem zoo li no tuaj yeem yog qhov tseem ceeb. NREL hais tias ob qho tib si qhib-qhov mining thiab txoj kev ntsev flats " tuaj yeem ua rau kev puas tsuaj hauv av, muaj peev xwm kis tau, thiab kev siv dej ntau, tshwj xeeb hauv cov cheeb tsam uas twb muaj kev kub ntxhov thiab suab puam." Nws ntxiv tias lawv kuj siv ntau qhov chaw.

DLE, los ntawm qhov sib txawv, tso cai rau "kev siv lithium kom ruaj khov dua, suav nrog kev siv hluav taws xob hauv hluav taws xob los ua lub zog txuas ntxiv mus rau kev tsim khoom."

Thauj & Ib puag ncig tus Poliscanova tau hais ntxiv txog qhov tseem ceeb ntawm geothermal lithium ntxiv dag zog rau kev rov ua dua tshiab thiab cov tswv yim hais txog kev lag luam ncig. Recycling, tom qab ntawd nws hais tias, yuav tsum yog "qhov tseem ceeb thib ib."

Kev rov ua dua tshiab yeej zoo li nws yuav muaj lub luag haujlwm tseem ceeb los ua mus tom ntej, tshwj xeeb tshaj yog nyob rau hauv EV sector. Elon Musk's Tesla, piv txwv li, hais tias tag nrho nws cov roj teeb lithium-ion tau rov ua dua.

Thiab rov qab rau lub Kaum Ib Hlis, Swedish roj teeb tuam txhab Northvolt tau hais tias nws tau tsim nws thawj lub roj teeb ntawm tes nrog qhov nws tau piav qhia tias "100% rov siv dua nickel, manganese thiab cobalt."

Rov qab rau hauv Cornwall, GeoCubed qhov project txuas ntxiv mus. Nyuam qhuav pib lub hlis no, nws tau hais tias nws tau xaiv ib lub tuam txhab hu ua Ross-shire Engineering los muab nws cov kev sim cog nrog kev txhawb nqa ntsig txog engineering, kev yuav khoom, kev tsim kho thiab commissioning, lossis EPCC.

Nws cov lus tseem hais txog qhov kev ntsuas hluav taws xob submersible twj tso kua mis ua los ntawm GEL thaum Lub Yim Hli 2021, uas ua rau muaj kev sau ntawm "cov qauv ntawm cov dej kub hauv ntiaj teb."

GeoCubed tau hais tias qib ntawm lithium concentrations hauv cov qauv yog "txhawb," thiab ntxiv tias "lwm cov khoom lag luam tseem ceeb xws li caesium, rubidium thiab potassium tau pom tias yog qib siab."

Yog tias txhua yam mus rau txoj kev npaj, lub chaw tsav tsheb yuav raug tso cai los ntawm lub Peb Hlis kawg ntawm lub xyoo no.
