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

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

Kamfanin ya aiwatar da shigarwar 250 kW Kirkirar Kirkira. A nan gaba, irin wannan na'ura mai karfin megawatt 3 zai maye gurbin na'urorin samar da diesel na gargajiya, wadanda a halin yanzu ake amfani da su a matsayin tushen wutar lantarki a cibiyoyin bayanai.

Ana daukar hydrogen a matsayin man da ba zai dace da muhalli ba saboda konewarsa yana samar da ruwa ne kawai.

Microsoft ya saita aiki gaba daya maye gurbin dukkan injinan dizal a cibiyoyin bayanan su nan da 2030.

Kamar yadda yake a sauran cibiyoyin bayanai, cibiyoyin bayanan Azure suna amfani da janareta na diesel a matsayin tushen wutar lantarki lokacin da wutar lantarkin da ke kan babbar tashar ta ɓace. Wannan kayan aikin ba shi da aiki kashi 99% na lokaci, amma cibiyar bayanai har yanzu tana kiyaye ta cikin tsari don ta yi aiki cikin sauƙi idan aka sami gazawar da ba kasafai ba. A aikace, a Microsoft, ana yin gwajin aikin kowane wata da gwajin nauyi na shekara-shekara, lokacin da ainihin abin da ke cikin su ya kai ga sabobin. Babban gazawar wutar lantarki ba ya faruwa kowace shekara.

Duk da haka, ƙwararrun Microsoft sun ƙididdige cewa sabbin samfuran ƙwayoyin man hydrogen sun riga sun fi tsada fiye da injinan diesel.

Bugu da kari, samar da wutar lantarki (UPS) a yanzu yana amfani da batura masu samar da wuta a cikin kankanin tazara (dakika 30 zuwa minti 10) tsakanin katsewar wutar da kuma tayar da injinan diesel. Na karshen suna iya ci gaba da aiki har sai man fetur ya ƙare.

Tantanin man fetur na hydrogen ya maye gurbin duka UPS da janareta na diesel. Ya ƙunshi tankunan ajiyar hydrogen da na'urar lantarki, wanda ke raba kwayoyin ruwa zuwa hydrogen da oxygen. Anan ga abin da ƙirar Innovations Power 250kW yayi kama da gaske:

Ana haɗa shigarwa kawai zuwa cibiyar sadarwar lantarki da ake da ita - kuma baya buƙatar samar da mai daga waje, kamar janareta na diesel. Ana iya haɗa shi da hasken rana ko filayen iska, wanda zai samar da isasshen hydrogen don cika tankuna. Don haka, ana amfani da hydrogen a matsayin baturi mai sinadari don masana'antar wutar lantarki da hasken rana.

A cikin 2018, masu bincike daga Laboratory Renewable Energy Laboratory a Colorado (Amurka) sun gudanar da gwajin nasara na farko game da sarrafa tarin sabar daga sel mai ta amfani da PEM (proton Exchange membrane), wato, akan. proton musayar membranes.

PEM sabuwar fasaha ce don samar da hydrogen. Yanzu irin wannan shigarwa a hankali yana maye gurbin electrolysis na al'ada na al'ada. Zuciyar tsarin ita ce tantanin halitta electrolysis. Yana da nau'ikan lantarki guda biyu, cathode da anode. Tsakanin su akwai wani m electrolyte, wannan shi ne proton musayar membrane da aka yi da wani high-tech polymer.

Ta hanyar fasaha, protons suna gudana a hankali a cikin membrane, yayin da electrons ke motsawa ta hanyar waje. Ruwan da aka lalatar yana gudana zuwa anode, inda aka raba shi zuwa protons, electrons da iskar oxygen. Protons suna wucewa ta cikin membrane, yayin da electrons ke motsawa ta hanyar da'ira na waje. A cathode, protons da electrons suna haɗuwa don samar da iskar hydrogen (H2).

Wannan babban aiki ne na musamman, abin dogaro, hanya mai inganci don samar da hydrogen kai tsaye a wurin amfani. Sannan, idan hydrogen da oxygen suka haɗu, ana samun tururin ruwa kuma ana samar da wutar lantarki.

A cikin watan Satumba na 2019, Ƙirƙirar Ƙarfafawa ta fara gwaji tare da tantanin mai mai kilowatt 250 wanda ke ba da cikakken ɗakunan sabar 10. A watan Disamba, tsarin ya wuce gwajin aminci na sa'o'i 24, kuma a watan Yuni 2020 - gwajin awoyi 48.

A lokacin gwaji na ƙarshe, irin waɗannan ƙwayoyin mai guda huɗu suna aiki a yanayin atomatik. Adadin rikodin rikodin:

• 48 hours na ci gaba da aiki
• 10 kWh na wutar lantarki da aka samar
• 814 kg na hydrogen amfani
• An samar da lita 7000 na ruwa

Yanzu haka dai kamfanin na shirin yin amfani da wannan fasaha domin kera man fetur mai karfin megawatt 3. Yanzu zai kasance da cikakken kwatankwacin iko ga injinan dizal da aka sanya a cibiyoyin bayanan Azure.

Ƙungiya ta duniya tana haɓaka hydrogen a matsayin mai Majalisar Hydrogen, wanda ke haɗa masana'antun kayan aiki, kamfanonin sufuri da manyan abokan ciniki - Microsoft ya riga ya nada wakili a wannan majalisa. A ka'ida, duk fasahar samar da hydrogen da samar da wutar lantarki sun riga sun kasance. Aikin kungiyar shine auna su. Har yanzu da sauran aiki a nan.

Masana suna ganin kyakkyawar makoma ga ƙwayoyin mai irin PEM. A cikin shekaru biyu da suka gabata, farashin su ya ragu da kusan sau huɗu. Suna daidai da daidaitattun tashoshi na hotovoltaic da iska, suna tara kuzari yayin lokutan mafi girman tsara - kuma suna sakin shi cikin hanyar sadarwa a lokutan babban nauyi.

Bugu da ƙari, ana iya amfani da su don dillalai a kan musayar makamashi, inda tsarin ke siyan makamashi a lokacin mafi ƙanƙanta ko ma. korau farashin - kuma yana ba da shi a lokuta mafi girman ƙima. Irin waɗannan tsarin dillalai na iya aiki ta atomatik, kamar bots ɗin ciniki.

Hakoki na Talla

Wurin samar da wutar lantarki na cibiyoyin bayanan mu ba sa aiki akan hydrogen, amma amincin su yana da kyau! Mu almara sabobin - waɗannan suna da ƙarfi VDS a Moscow, wanda ke amfani da na'urori na zamani daga AMD.
