Samar da ƙwayoyin mai da tankunan hydrogen sun fi muni ga muhalli fiye da batura [ICCT]

Kimanin wata guda da ya gabata ne Hukumar Kula da Sufuri ta Kasa da Kasa (ICCT) ta fitar da wani rahoto kan hayakin da ake kerawa da amfani da kuma zubar da motocin kone-kone da na'urorin toshewa, motocin lantarki da motocin dakon mai (hydrogen). Duk wanda ya kalli ginshiƙi zai yi mamaki: psamar da baturi yana haifar da ƙananan hayaki mai gurbata yanayi da ƙananan nauyin muhalli fiye da samar da ƙwayoyin mai da tankunan hydrogen..

Tankunan hydrogen sun fi batura muni ga muhalli. Kuma muna magana ne kawai game da shigarwa, ba samarwa ba.

Rahoton ICCT LCA (Life Cycle Analysis) za a iya sauke shi NAN. Ga ɗaya daga cikin jadawali da aka ambata, duba shafi na 16 a cikin rahoton. Yellow - samar da batura a cikin zamani na zamani (tare da ma'auni na makamashi na yanzu), ja - samar da tanki na hydrogen tare da kwayoyin man fetur, mafi muni:

Mun ɗan yi mamaki, mun tambayi ICCT game da waɗannan bambance-bambancen saboda Gabaɗaya an yarda cewa hakar albarkatun ƙasa da kera batirin lithium-ion matakai ne na "datti", kuma ana ɗaukar ƙwayoyin mai ko tankunan hydrogen suna da tsabta.domin "ba duk wannan maganar banza ba ce." Ya zama babu kuskure: dangane da fitar da CO₂, Samar da batura ya fi dacewa da muhalli da rashin cutarwa ga muhalli fiye da samar da kwayoyin halitta da tafki.

Dokta Georg Bicker, shugaban marubucin rahoton, ya shaida mana cewa, ya yi amfani da tsarin GREET da Argonne National Laboratory, wani dakin bincike na Ma'aikatar Makamashi ta Amurka, ya tsara, wajen shirya bayanan. Bari mu jaddada: wannan ba wani nau'i ne na cibiyar bincike ba, amma wani abu ne, wanda sakamakonsa a fagen makamashin nukiliya, madadin makamashin makamashi da rediyoactivity an san su a duk duniya.

Dangane da girman abin hawa da wurin siyarwa, watau daga tushen baturi, iskar gas (GHG) tana fitowa daga tan 1,6 na CO daidai.₂ don ƙananan hatchbacks a Indiya (batir 23 kWh) har zuwa ton 5,5 na CO daidai₂ don SUVs da SUVs a cikin Amurka (batir 92 kWh; Table 2.4 a ƙasa). A matsakaita ga dukkan sassan yana da kusan tan 3-3,5 na CO-daidai.₂... Production rarraba ya haɗa da sake yin amfani da su, idan da gaske ne, zai kasance ƙasa da kashi 14-25 bisa ɗari, ya danganta da tsarin sake yin amfani da shi da adadin albarkatun da aka kwato.

Don kwatantawa: samar da ƙwayoyin mai da tankunan hydrogen suna fitar da tan 3,4-4,2 na CO daidai₂ bisa ga samfurin GREET ko 5 ton na CO daidai₂ a cikin wasu samfurori (shafi na 64 da 65 na rahoton). Abin takaici, ba wai dawo da platinum da ake amfani da shi a cikin sel mai ne ke ɗaukar nauyi mafi girma akan muhalli ba, amma ƙirƙira na carbon fiber-ƙarfafa hadadden tankunan hydrogen... Ba abin mamaki ba ne cewa Silinda dole ne ya yi tsayayya da wani gigantic matsa lamba na 70 MPa, don haka yana auna da yawa dubun kilo, ko da yake zai iya kawai rike da 'yan kilo na gas.
