A MA­JOR ECO­NOMIC doc­u­ment has high­lighted the fi­nan­cial com­pet­i­tive­ness of elec­tric buses over con­ven­tion­ally fu­elled models, giv­ing in­sight into the tech­nol­ogy’s po­ten­tially un­fore­seen rapid ac­cep­tance for bus fleets glob­ally, as re­ported re­cently.

Bloomberg’s Elec­tric Buses in Ci­ties: Driv­ing To­wards Cleaner

Air and Lower CO2 - au­thored by Bloomberg New En­ergy Fi­nance (BNEF) on be­half of the C40 Ci­ties Cli­mate Lead­er­ship Group – high­lights an elec­tric, or an ‘e-buses’, com­pet­i­tive­ness against con­ven­tional diesel and CNG fu­elled modes.

It states, “air qual­ity is a grow­ing con­cern in many ur­ban en­vi­ron­ments and has di­rect health im­pli­ca­tions for res­i­dents. Tailpipe emis­sions from in­ter­nal com­bus­tion en­gines are one of the ma­jor sources of harm­ful pol­lu­tants such as ni­tro­gen ox­ides and particulates. Diesel en­gines in par­tic­u­lar have very high ni­tro­gen ox­ide emis­sions and yet these make up the ma­jor­ity of the global bus fleet.”

The Bloomberg re­port adds that: “As the world’s ur­ban pop­u­la­tion con­tin­ues to grow, iden­ti­fy­ing sus­tain­able, cost-ef­fec­tive trans­port op­tions is be­com­ing more crit­i­cal. Elec­tric ve­hi­cles – in­clud­ing elec­tric buses – are one of the most promis­ing ways of re­duc­ing harm­ful emis­sions and im­prov­ing over­all air qual­ity in ci­ties.”

“E-buses have much lower op­er­at­ing costs and can al­ready be cheaper, on the ba­sis of to­tal cost of own­er­ship, than con­ven­tional buses to­day. The TCO of all elec­tric bus con­fig­u­ra­tions that we mod­elled im­proves sig­nif­i­cantly in re­la­tion to diesel buses as the num­ber of kilo­me­tres trav­elled an­nu­ally in­creases. For ex­am­ple, a 110kWh bat­tery e-bus cou­pled with the most ex­pen­sive wire­less charg­ing reaches TCO par­ity with diesel bus at around 60,000km trav­elled per year (37,000 miles). This means that a bus with the small­est bat­tery, even when cou­pled with the most ex­pen­sive charg­ing op­tion, would be cheaper to run in a medium sized city, where buses travel on av­er­age 170km/day (106 miles).”
