Ukukhiqiza ama-fuel cell kanye namathangi e-hydrogen KUBI endaweni ezungezile kunamabhethri [ICCT]

Cishe enyangeni edlule, i-International Clean Transport Council (ICCT) yakhipha umbiko mayelana nekhabhoni yokukhiqiza, ukusetshenziswa nokulahlwa kwezimoto ezivuthayo, ama-plug-in hybrids, izimoto zikagesi kanye nezimoto zamafutha (i-hydrogen). Noma ubani oke wabhekisisa amashadi angase amangale: pukukhiqizwa kwebhethri kuholela ekukhiqizweni kwegesi ebamba ukushisa ephansi kanye nomthwalo wemvelo ophansi kunokukhiqizwa kwamaseli kaphethiloli namathangi e-hydrogen..

Amathangi e-hydrogen mabi kakhulu emvelweni kunamabhethri. Futhi sikhuluma kuphela ngokufaka, hhayi ukukhiqiza.

Umbiko we-ICCT LCA (Ukuhlaziywa Komjikelezo Wokuphila) ungalandwa LAPHA. Nali elinye lamagrafu okukhulunywe ngalo, bheka ikhasi 16 embikweni. Okuphuzi - ukukhiqizwa kwamabhethri ezweni lanamuhla (enebhalansi yamandla yamanje), okubomvu - ukukhiqizwa kwethangi le-hydrogen elinamaseli kaphethiloli, kukhulu kubi:

Simangele kancane, sabuza i-ICCT ngalo mehluko ngoba Kuyamukelwa ngokuvamile ukuthi ukukhishwa kwezinto zokusetshenziswa kanye nokukhiqizwa kwamabhethri e-lithium-ion kuyizinqubo "ezingcolile", futhi amangqamuzana kaphethiloli noma amathangi e-hydrogen abhekwa njengehlanzekile.ngoba "akuwona wonke lombhedo." Kuvele ukuthi alikho iphutha: ngokwemibandela ye-CO ekhishwayo₂, ukukhiqizwa kwamabhethri kuhambisana kakhulu nemvelo futhi akulimazi kangako imvelo kunokukhiqizwa kwamaseli namadamu.

UDkt. Georg Bicker, umbhali oholayo walo mbiko, usitshele ukuthi usebenzise imodeli ye-GREET eyakhiwe yi-Argonne National Laboratory, ilabhorethri yocwaningo yoMnyango Wezamandla wase-US, ukulungisa izitatimende. Ake sigcizelele: lokhu akulona uhlobo oluthile lwesikhungo sokucwaninga, kodwa into, imiphumela yayo emkhakheni wamandla enuzi, imithombo yamandla ehlukile kanye ne-radioactivity eyaziwa emhlabeni wonke.

Ngokuya ngosayizi wemoto kanye nendawo edayiswayo, okungukuthi kusukela emthonjeni webhethri, ukukhishwa kwegesi ebamba ukushisa (GHG) kusuka kumathani angu-1,6 e-CO elingana.₂ kuma-hatchback amancane e-India (23 kWh ibhethri) kufika kumathani angu-5,5 we-CO elingana₂ kumaSUV namaSUV ase-US (92 kWh ibhethri; Ithebula 2.4 ngezansi). Ngokwesilinganiso kuwo wonke amasegimenti cishe amathani angu-3-3,5 we-CO-elingana.₂... Ukukhiqiza ngokwezigaba kufaka phakathi ukugaywa kabusha, uma bekunjalo, bekuzoba ngaphansi ngamaphesenti angu-14-25, kuye ngenqubo yokugaywa kabusha kanye nenani lezinto zokusetshenziswa ezitholiwe.

Qhathanisa: ukukhiqizwa kwamaseli kaphethiloli kanye namathangi e-hydrogen kukhipha amathani angu-3,4-4,2 we-CO elingana₂ ngokwemodeli ye-GREET noma amathani angu-5 we-CO elingana₂ kwamanye amamodeli (ikhasi 64 kanye nelama-65 lombiko). Okuxakayo ukuthi, akukhona ukutholwa kwe-platinum esetshenziswa kuma-fuel cell okuthwala umthwalo omkhulu emvelweni, kodwa. ukwakhiwa kwamathangi e-hydrogen ahlanganiswe ne-carbon fiber-reinforced... Akumangalisi ukuthi isilinda kufanele simelane nokucindezela okukhulu kwe-MPa engu-70, ngakho-ke inesisindo esingamakhilogremu amaningana, nakuba ingabamba amakhilogremu ambalwa wegesi.
