A ranar 8 ga Mayu, kamfanin RAG na Austria ya ƙaddamar da aikin gwaji na farko na adana hydrogen a ƙarƙashin ƙasa a wani tsohon wurin ajiyar iskar gas da ke Rubensdorf. Aikin gwaji zai adana mita cubic 1.2 na hydrogen, daidai da 4.2 GWh na wutar lantarki. Za a samar da hydrogen da aka adana ta hanyar ƙwayar membrane na musayar proton mai ƙarfin MW 2 da Cummins ke samarwa, wanda da farko zai yi aiki a kan nauyin tushe don samar da isasshen hydrogen don ajiya. Daga baya a cikin aikin, ƙwayar za ta yi aiki ta hanyar da ta fi sassauƙa don canja wurin wutar lantarki mai sabuntawa zuwa ga grid.
A matsayin muhimmin ci gaba a ci gaban tattalin arzikin hydrogen, aikin gwaji zai nuna yuwuwar ajiyar hydrogen a ƙarƙashin ƙasa don adana makamashi na yanayi da kuma share fagen amfani da makamashin hydrogen mai yawa. Duk da cewa har yanzu akwai ƙalubale da yawa da za a shawo kansu, wannan tabbas muhimmin mataki ne zuwa ga tsarin makamashi mai ɗorewa da kuma rage gurɓataccen iska.
Ajiye hydrogen a ƙarƙashin ƙasa, wato amfani da tsarin ƙasa na ƙarƙashin ƙasa don adana makamashin hydrogen mai yawa. Ana samar da wutar lantarki daga tushen makamashi mai sabuntawa da kuma samar da hydrogen, ana saka hydrogen a cikin tsarin ƙasa na ƙasa kamar kogon gishiri, wuraren ajiyar mai da iskar gas da suka lalace, magudanar ruwa da kuma kogunan duwatsu masu tauri don samun damar adana makamashin hydrogen. Idan ya zama dole, ana iya cire hydrogen daga wuraren ajiyar hydrogen na ƙarƙashin ƙasa don iskar gas, samar da wutar lantarki ko wasu dalilai.
Ana iya adana makamashin hydrogen ta hanyoyi daban-daban, ciki har da iskar gas, ruwa, shaƙar saman, hydride ko ruwa tare da jikin hydrogen da ke cikin jirgin. Duk da haka, domin a cimma nasarar aiki mai kyau na hanyar samar da wutar lantarki ta ƙarin ƙarfi da kuma kafa cikakkiyar hanyar samar da makamashin hydrogen, ajiyar hydrogen a ƙarƙashin ƙasa ita ce hanya ɗaya tilo da za a iya cimmawa a halin yanzu. Tsarin ajiyar hydrogen a saman ƙasa, kamar bututun mai ko tankuna, suna da iyakantaccen damar ajiya da fitarwa na 'yan kwanaki kaɗan. Ana buƙatar ajiyar hydrogen a ƙarƙashin ƙasa don samar da ajiyar makamashi akan sikelin makonni ko watanni. Ajiye hydrogen a ƙarƙashin ƙasa na iya biyan buƙatun adana makamashi har zuwa watanni da yawa, ana iya cire shi don amfani kai tsaye lokacin da ake buƙata, ko kuma ana iya mayar da shi wutar lantarki.
Duk da haka, ajiyar hydrogen a ƙarƙashin ƙasa yana fuskantar ƙalubale da dama:
Na farko, ci gaban fasaha yana raguwa
A halin yanzu, bincike, haɓakawa da kuma nuna abubuwan da ake buƙata don adanawa a filayen iskar gas da suka lalace da kuma wuraren ruwa suna da jinkiri. Ana buƙatar ƙarin bincike don tantance tasirin iskar gas da ta rage a filayen da suka lalace, halayen ƙwayoyin cuta a cikin wuraren ruwa da kuma filayen iskar gas da suka lalace waɗanda za su iya haifar da gurɓataccen iska da asarar hydrogen, da kuma tasirin matsewar ajiya wanda halayen hydrogen za su iya shafar.
Na biyu, tsawon lokacin gina aikin yana da tsawo
Ayyukan adana iskar gas na ƙarƙashin ƙasa suna buƙatar tsawon lokaci mai tsawo na gini, shekaru biyar zuwa goma na kogo da wuraren adana gishiri da suka lalace, da kuma shekaru 10 zuwa 12 na adana ruwa. Ga ayyukan adana hydrogen, akwai yiwuwar samun jinkiri mai yawa na lokaci.
3. Yanayi na ƙasa ya iyakance shi
Muhalli na ƙasa yana ƙayyade yuwuwar wuraren adana iskar gas na ƙarƙashin ƙasa. A yankunan da ke da ƙarancin damar amfani, ana iya adana hydrogen a babban sikelin a matsayin mai ɗaukar ruwa ta hanyar tsarin canza sinadarai, amma ingancin canza makamashi kuma yana raguwa.
Duk da cewa ba a yi amfani da makamashin hydrogen a babban sikelin ba saboda ƙarancin inganci da tsadarsa, yana da babban damar ci gaba a nan gaba saboda muhimmiyar rawar da yake takawa wajen rage gurɓatar iskar carbon a fannoni daban-daban masu muhimmanci.
