I-UOW Spin-off Hysata Ibanga iTekhnoloji yeCfe Electrolyzer yokuVelisa ixabiso loKhuphiswano lweHydrojeni eluhlaza kungekudala

• I-Hysata ithi ukuphuculwa kwetekhnoloji ye-electrolyzer liqela lenza kube lula ukuvelisa i-hydrogen eluhlaza exabisa ngaphantsi kwe-1.50 yeedola ngekhilogram phakathi koo-2022.
• Iphuhlise itekhnoloji entsha ye-electrolyzer eneseli ye-CFE efezekisa ukusebenza kakuhle kwamandla okungama-98% okukhokelela ekusetyenzisweni kwamandla okuncinci yi-electrolyzer.
• Inkqubo ivumela i-electrolysis engenamaqamza kwaye isusa imisinga ye-shunt engafunekiyo neyilahleko efumaneka kwi-electrolyzers yamanzi ealkaline.
• Onke la manyathelo adityanisiweyo anceda ukuthoba umbane ohlaziyekayo ngokubanzi ofunwa yi-electrolyzer ukuvelisa i-hydrogen eluhlaza, ethoba i-capex yayo.

Phakathi koo-2020, imveliso ye-hydrogen eluhlaza engaphantsi kwe-1.50 yeedola ngekhilogram ifanele ukuba yenzeke ngeYunivesithi yase-Australia yase-Wollongong (UOW) ebanga ukuba iphuhlise itekhnoloji entsha ye-electrolyzer ene-capirally-fed electrolysis (CFE) iseli ngoku ethengiswa nge-spin-off Hysata.

Inkqubo ye-CFE ivumela i-electrolysis engenamaqamza nto leyo ethetha ukuba akukho amaqamza erhasi enziwayo kwaye amanzi aguqulwa ngokuthe ngqo abe ziigesi ezininzi. Ngaphaya koko, imisinga ye-shunt engafunekiyo neyilahleko efumaneka kwii-electrolyser zamanzi zealkaline eziqhelekileyo, zinokuthintelwa ngoncedo lwemithamo emincinci ye-electrolyte engamanzi kwireservoir yeeseli nganye. "Oku kwenziwa lula kwi-balance-of-plant kukhokelela kuxinzelelo olusezantsi kwi-electrolyser capex," litsho iqela.

Ngokomsebenzi wophando oye wapapashwa kwijenali yenzululwazi Nature Communications, iseli ye-CFE inokuvelisa i-hydrogen eluhlaza kumanzi kwi-98% ye-energy ye-cell energy engaphezulu kwe-International Renewable Energy Agency's (IRENA) 2050 target, ithi iqela.

Okwangoku, i-electrolyzer yamanzi yorhwebo yanamhlanje ithatha malunga ne-53 kWh yombane ukuvelisa i-1 kg ye-hydrogen equlethe i-39.4 kWh yamandla. Ngaphandle koku, iseli ye-electrolysis idla i-47.5 kWh yombane. Abaphandi bathi i-IRENA ibeke ithagethi yokunciphisa ukusetyenziswa kwamandla eseli ukuya ngaphantsi kwe-42 kWh ngekhilogram ngo-2050 eya kuba negalelo ekunciphiseni ixabiso elilinganisiweyo le-hydrogen eveliswayo.

Amaqabane eprojekthi abanga iseli ye-alkaline ye-CFE 'ibonisa ukusebenza kwe-electrolysis yamanzi edlula iiseli ze-electrolysis zorhwebo, kunye nombane weseli kwi-0.5 A cm−2 kunye ne-85 °C ye-1.51 V kuphela, elingana ne-98% yokusebenza kwamandla, kunye nokusetyenziswa kwamandla kwe-40.4 kWh / kg ye-hydrogen'.

Umphathi weHysata uPaul Barrett uthi: “I-electrolyzer yethu iya kuzisa elona xabiso liphantsi lehydrogen emhlabeni, yonge abavelisi behydrogen iibhiliyoni zeerandi kwiindleko zombane, kwaye yenze ukuba ihydrogen eluhlaza ikwazi ukoyisa i-hydrogen eyenziwe ngamafutha efosili.

I-CTO ye-Hysata uGerry Swiegers wongeze wathi, "Inkqubo ye-electrolyzer ye-Hysta iyonke yenzelwe ukwenza lula, ukukala kunye nokufakelwa, ukuhambisa iipesenti ezingama-95 ukusebenza kakuhle kwenkqubo, elingana ne-41.5 kWh/kg, xa kuthelekiswa neepesenti ezingama-75 okanye ngaphantsi kubuchwephesha obukhoyo be-electrolyzer."
