A ranar 8 ga Mayu, RAG na Ostiriya ya ƙaddamar da aikin gwajin ajiyar hydrogen na farko a duniya a wani tsohon ma'ajiyar iskar gas a Rubensdorf. Aikin gwajin zai tanadi hydrogen cubic mita miliyan 1.2, kwatankwacin wutar lantarki 4.2 GWh. Za a samar da hydrogen ɗin da aka adana ta wani tantanin musanya na proton 2 MW wanda Cummins zai samar, wanda zai fara aiki da nauyin nauyi don samar da isasshen hydrogen don ajiya. Daga baya a cikin aikin, tantanin halitta zai yi aiki a cikin mafi sassauƙa don canja wurin ƙarin wutar lantarki mai sabuntawa zuwa grid.
A matsayin wani muhimmin ci gaba a ci gaban tattalin arzikin hydrogen, aikin matukin jirgin zai nuna yuwuwar ajiyar hydrogen ta karkashin kasa don ajiyar makamashi na yanayi da kuma shimfida hanyar tura makamashin hydrogen mai yawa. Duk da yake akwai sauran ƙalubale masu yawa da za a shawo kan su, wannan tabbas wani muhimmin mataki ne ga tsarin samar da makamashi mai ɗorewa.
Ma'ajiyar hydrogen ta karkashin kasa, wato yin amfani da tsarin yanayin kasa don yawan ajiyar makamashin hydrogen. Samar da wutar lantarki daga hanyoyin samar da makamashi da ake sabuntawa da samar da hydrogen, ana shigar da hydrogen zuwa cikin gine-ginen kasa na karkashin kasa kamar kogon gishiri, rarar mai da tafkin iskar gas, magudanan ruwa da kogon dutsen da aka lika domin samun damar adana makamashin hydrogen. Idan ya cancanta, ana iya fitar da hydrogen daga wuraren ajiyar hydrogen na karkashin kasa don iskar gas, samar da wutar lantarki ko wasu dalilai.
Ana iya adana makamashin hydrogen ta nau'i-nau'i daban-daban, ciki har da gas, ruwa, tallan sararin samaniya, hydride ko ruwa tare da jikin hydrogen. Duk da haka, don gane da santsi aiki na karin wutar lantarki grid da kuma kafa cikakken hydrogen makamashi cibiyar sadarwa, karkashin kasa hydrogen ajiya ne kawai m hanya a halin yanzu. Siffofin ma'ajiyar hydrogen, kamar bututu ko tankuna, suna da iyakataccen ajiya da iya fitarwa na 'yan kwanaki kawai. Ana buƙatar ma'ajiyar hydrogen ta ƙasa don samar da ajiyar makamashi akan ma'aunin makonni ko watanni. Ajiye hydrogen na karkashin kasa zai iya biyan har zuwa watanni da yawa na bukatun ajiyar makamashi, ana iya fitar da shi don amfani kai tsaye lokacin da ake buƙata, ko kuma ana iya canza shi zuwa wutar lantarki.
Duk da haka, ajiyar hydrogen a karkashin kasa yana fuskantar kalubale da dama:
Na farko, ci gaban fasaha yana sannu a hankali
A halin yanzu, bincike, haɓakawa da nunin da ake buƙata don adanawa a cikin gurɓataccen filayen iskar gas da magudanan ruwa yana jinkirin. Ana buƙatar ƙarin karatu don tantance tasirin ragowar iskar gas a cikin filayen da ba a cika ba, a cikin halayen ƙwayoyin cuta a cikin magudanar ruwa da gurɓataccen filayen iskar gas wanda zai iya haifar da gurɓataccen abu da asarar hydrogen, da kuma tasirin ƙarancin ajiya wanda kaddarorin hydrogen ke iya shafa.
Na biyu, lokacin gina aikin yana da tsawo
Ayyukan ajiyar iskar gas na ƙarƙashin ƙasa suna buƙatar tsawon lokaci na gini, shekaru biyar zuwa 10 don kogon gishiri da tafkunan da ba su ƙare ba, da shekaru 10 zuwa 12 don ajiyar ruwa. Don ayyukan ajiyar hydrogen, za a iya samun larura mafi girma.
3. Iyakance ta yanayin yanayin ƙasa
Yanayin yanayin ƙasa na gida yana ƙayyade yuwuwar wuraren ajiyar iskar gas na ƙarƙashin ƙasa. A cikin yankunan da ke da iyakacin iyaka, ana iya adana hydrogen a kan babban sikeli a matsayin mai ɗaukar ruwa ta hanyar tsarin jujjuya sinadarai, amma kuma ana rage tasirin canjin makamashi.
Ko da yake ba a yi amfani da makamashin hydrogen akan babban sikeli ba saboda ƙarancin ingancinsa da tsadarsa, yana da fa'ida mai fa'ida ga ci gaban gaba a nan gaba saboda muhimmiyar rawar da yake takawa wajen rage ƙonawa a fagage daban-daban.
