ELECTRIC BUSES COMPETITIVE AGAINST FUELLED
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).”
