"CO2 ibhethri". AmaNtaliyane ahlinzeka ngezinhlelo zokugcina amandla ezisuselwe ekuncibilikeni kwe-carbon dioxide. Kushibhile kune-hydrogen, lithium, ...

Isiqalisi sase-Italy i-Energy Dome sesenze idivayisi yokugcina amandla ebiza ngokuthi “ibhethri le-CO.₂“Ibhethri elisebenzisa ukuguqulwa kwesigaba se-carbon dioxide ibe uketshezi negesi. Indawo yokugcina impahla isetshenziselwa ukugcina amandla isikhathi eside, iyasebenza kakhulu futhi ishibhile ngokwedlulele, ibiza ngaphansi kwama-$100 i-MWh ngayinye.

Ukushintsha kwesigaba se-carbon dioxide esikhundleni se-lithium, i-hydrogen, umoya, amandla adonsela phansi

I-Energy Dome ithi ayidingi izixazululo ezikhethekile, izakhi ezitholakala esidlangalaleni zanele. Izindleko zamanje ezilinganiselwe zokugcina i-1 MWh yamandla ingaphansi kwama-$100 (okulingana ne-PLN 380), kodwa ukuqalisa kulinganisela ukuthi izokwehla ibe ngama-$50-60/MWh eminyakeni embalwa ezayo. Ukuze uqhathanise: ngamabhethri e-lithium-ion yi-132-245 dollars / MWh, enomoya omanzi - cishe amadola ayi-100 / MWh endaweni yokugcina impahla ekwazi ukuthola amandla angu-100 MW (umthombo).

Kulindeleke ukuthi ukusebenza kahle kwendawo yokugcina impahla kusetshenziswa ukuguqulwa kwesigaba se-carbon dioxide kuzoba ngamaphesenti angama-75-80.ngakho-ke idlula noma ibuphi obunye ubuchwepheshe bokugcina amandla esikhathi eside emakethe. Lokhu akusebenzi ku-hydrogen kuphela, kodwa nasemoyeni, endaweni yokugcina amandla adonsela phansi noma isitoreji somoya esicindezelwe noma esijiyile.

E-Energy Dome, i-carbon dioxide ingaphansi kwengcindezi engu-70 bar (7 MPa), eyishintsha ibe uketshezi olushiswe ku-300 degrees Celsius. Amandla ashisayo alolu shintsho lwesigaba agcinwa "ezitini" ze-quartzite ne-steel shot, kuyilapho i-CO ewuketshezi.₂ ingena emathangeni enziwe ngensimbi ne-carbon fiber. I-cubic meter ngayinye yegesi izogcina u-66,7 kWh..

Lapho ukuvuselelwa kwamandla ("ukukhipha") kuyadingeka, uketshezi luyashisa futhi lunwebe, luguqule i-carbon dioxide ibe igesi. Ukunwetshwa kwamandla kushayela i-turbine, okuholela ekukhiqizeni amandla. I-carbon dioxide ngokwayo idlula ngaphansi kwe-dome ekhethekile eguquguqukayo, ezoyigcina kuze kube yilapho isetshenziswa ngokulandelayo.

I-Energy Dome ihlose ukwakha iyunithi yokugcina amandla eyisibonelo enamandla angu-4 MWh namandla angu-2,5 MW ngo-2022. Okulandelayo kuzoba umkhiqizo omkhulu wezohwebo onamandla angu-200 MWh namandla afinyelela ku-25 MW. Ngokusho komsunguli wokuqalisa, i-carbon dioxide ingcono kunomoya ngoba ingashintshwa ibe uketshezi ngo-30 degrees Celsius. Ngomoya, kuyadingeka ukwehla ku--150 degrees Celsius, okwandisa ukusetshenziswa kwamandla ngesikhathi senqubo.

Yiqiniso, "ibhethri ye-CO2" enjalo ayifanele ukusetshenziswa ezimotweni. - kodwa ingasetshenziswa ukugcina amandla engeziwe akhiqizwa emithonjeni evuselelekayo, amapulazi elanga noma ama-wind turbines.

Kuyafaneleka ukufunda: Ibhethri elisha le-carbon dioxide lizokwenza ukuthunyelwa komoya nelanga "ngezindleko eziphansi ezingakaze zibonwe"

Isithombe sesethulo: ukubona ngeso, ipulazi lomoya kanye ne-Energy Dome enesici esibonakalayo (c) I-Energy Dome

Lokhu kungase kube nentshisekelo kuwe:
