Sabar a cibiyar bayanan Microsoft sun yi aiki na kwanaki biyu akan hydrogen

Microsoft sanar game da babban gwaji na farko a duniya da aka yi ta amfani da ƙwayoyin man fetur na hydrogen don samar da wutar lantarki ga sabar bayanai a cibiyar bayanai.

Kamfanin ne ya gudanar da aikin gina tashar wutar lantarki mai karfin 250 kW. Sabbin Sabbin Dabaru na Wutar LantarkiA nan gaba, irin wannan shigarwa mai karfin megawatt 3 zai maye gurbin janareto na dizal na gargajiya, wanda a halin yanzu ake amfani da shi azaman tushen wutar lantarki a cibiyoyin bayanai.

Ana ɗaukar hydrogen a matsayin mai da ke da illa ga muhalli domin ƙonewarsa yana samar da ruwa ne kawai.

Microsoft ya shirya aikin maye gurbin dukkan janareton dizal a cibiyoyin tattara bayanai nata gaba daya nan da shekarar 2030.

Kamar yadda yake a sauran cibiyoyin bayanai, cibiyoyin bayanai na Azure suna amfani da janareta na dizal a matsayin tushen wutar lantarki idan babban layin wutar lantarki ya mutu. Wannan kayan aiki yana aiki kusan kashi 99% na lokaci, amma cibiyar bayanai har yanzu tana kula da shi don tabbatar da cewa ba a katse aiki ba idan ba kasafai ake samun matsala ba. A aikace, a Microsoft, waɗannan janareta suna yin gwajin lafiya na wata-wata da gwajin kaya na shekara-shekara ne kawai, inda suke isar da kaya ga sabar. Babban katsewar wutar lantarki ba ya faruwa kowace shekara.

Duk da haka, ƙwararrun Microsoft sun ƙididdige cewa sabbin samfuran ƙwayoyin man fetur na hydrogen sun riga sun fi rahusa fiye da janareton dizal.

Bugu da ƙari, yanzu ana amfani da batura don samar da wutar lantarki mai ɗorewa (UPS), wanda ke samar da wutar lantarki na ɗan gajeren lokaci (daƙiƙa 30 zuwa mintuna 10) tsakanin katsewar wutar lantarki da kunna janareton dizal. Na biyun zai iya aiki akai-akai har sai man fetur ya ƙare.

Tarin man fetur na hydrogen yana maye gurbin UPS da janareta na dizal. Ya ƙunshi tankunan ajiya na hydrogen da kuma na'urar electrolysis wadda ke raba ƙwayoyin ruwa zuwa hydrogen da oxygen. Ga yadda samfurin Power Innovations mai ƙarfin 250 kW yake a rayuwa ta ainihi:

Tsarin yana haɗuwa ne kawai da layin wutar lantarki na yanzu kuma baya buƙatar isar da mai daga waje, kamar janareta na dizal. Ana iya haɗa shi da bangarorin hasken rana ko injinan iska, wanda ke samar da isasshen hydrogen don cike tankuna. Don haka, ana iya amfani da hydrogen a matsayin na'urar adana makamashin sinadarai don injinan hasken rana da iska.

A shekarar 2018, masu bincike daga dakin gwaje-gwajen makamashi mai sabuntawa na kasa da ke Colorado (Amurka) sun gudanar da gwajin farko mai nasara wanda ke ba da wutar lantarki ga wani rumbun adana bayanai na uwar garken tare da ƙwayoyin man fetur na PEM (proton exchange membrane), wato, membranes na musayar proton.

PEM sabuwar fasaha ce ta samar da hydrogen. Waɗannan tsarin suna maye gurbin electrolysis na gargajiya na alkaline a hankali. Zuciyar tsarin ita ce tantanin lantarki. Tana ɗauke da electrodes guda biyu, cathode da anode. Tsakaninsu akwai wani electrolyte mai ƙarfi—wani membrane na musayar proton da aka yi da wani babban polymer mai fasaha.

A cikin wannan tsari, protons suna gudana a hankali a cikin membrane, yayin da electrons ke motsawa ta hanyar wata hanya ta waje. Ruwan da aka cire ion ya shiga anode, inda aka raba shi zuwa protons, electrons, da iskar oxygen. Protons suna ratsa membrane, kuma a matsayin electrons, suna motsawa ta hanyar da'irar lantarki ta waje. A cathode, protons da electrons suna sake haɗuwa, suna samar da iskar hydrogen (H2).

Wannan hanya ce mai matuƙar inganci, abin dogaro, kuma mai araha don samar da hydrogen kai tsaye a wurin da ake amfani da shi. Sannan hydrogen da oxygen suna haɗuwa don samar da tururin ruwa da samar da wutar lantarki.

A watan Satumba na 2019, Power Innovations ta fara gwaji da na'urar mai mai karfin kilowatt 250, wacce ke samar da isasshen wutar lantarki don samar da cikakken rack na uwar garken guda 10. Tsarin ya ci jarrabawar aminci ta awanni 24 a watan Disamba, da kuma gwajin awanni 48 a watan Yunin 2020.

A lokacin gwajin da ya gabata, irin waɗannan ƙwayoyin mai guda huɗu suna aiki a yanayin atomatik. alkaluman aikin da aka yi rikodin:

• Awanni 48 na aiki akai-akai
• 10,560 kWh na wutar lantarki da aka samar
• An yi amfani da kilogiram 814 na hydrogen
• An samar da lita 7000 na ruwa

Kamfanin yanzu yana shirin amfani da irin wannan fasaha don tsara na'urar mai mai ƙarfin megawatt 3. Ƙarfinsa zai yi daidai da na janaretocin dizal da aka sanya a cibiyoyin bayanai na Azure.

Wata kungiya ta duniya tana tallata sinadarin hydrogen a matsayin mai. Majalisar Hydrogen, wanda ya haɗa masana'antun kayan aiki, kamfanonin sufuri, da manyan abokan ciniki—Microsoft ta riga ta naɗa wakili a wannan majalisar. Ainihin, duk fasahohin samar da hydrogen da samar da wutar lantarki sun riga sun kasance a shirye. Manufar ƙungiyar ita ce haɓaka su. Har yanzu akwai aiki da yawa da za a yi.

Masana na ganin kyakkyawar makoma ga ƙwayoyin mai na PEM. Farashinsu ya faɗi kusan ninki huɗu a cikin shekaru biyu da suka gabata. Sun kasance abin ƙarfafawa ga tashoshin samar da wutar lantarki ta lantarki da ta iska, suna adana makamashi a lokacin da ake samar da wutar lantarki mafi girma kuma suna sake shi zuwa ga wutar lantarki a lokacin da ake buƙatar wutar lantarki mafi girma.

Kuma, ana iya amfani da su don dillanci a musayar makamashi, inda tsarin ke siyan makamashi a lokacin mafi ƙaranci ko ma mafi ƙaranci. farashi mara kyau — kuma ya sake shi a farashi mafi tsada. Irin waɗannan tsarin dillalai na iya aiki ta atomatik, kamar cinikin bot.
