ELECTRIC BUS SERIES
EPISODE 1 : INTRODUCTION TO E-BUSES
The transition to e-buses will reap enormous economic, environmental and social benefits, which include emissions reduction in the absence of tailpipe emissions, reducing air and noise pollution leading to improved public health, and reduced total cost of ownership from lower maintenance costs and energy use. However, common barriers of adopting e-buses into a fleet by bus operators often include uncertainties regarding energy use, charging infrastructure, upstream infrastructure upgrades, and initial costs for the new technology.
Recent trends in the e-bus market
Globally, electric buses constitute the fastest-growing part of the EV market, with a compound annual growth rate of more than 100 percent since 2013, compared with 60 percent for fully electric passenger cars. There are nearly half a million e-buses in operation throughout the world, with more than 90% of these in China. Bloomberg predicts that by 2030, 84 percent of global municipal bus sales will be electric. This is important - buses are big and in constant use - so electrification of bus fleets constitutes significant savings in green house gas emissions. BNEF estimates that 500 barrels of diesel are displaced each day for every 1,000 e-buses on the road.
In October 2019, the NSW Government announced plans to transition Sydney’s entire bus fleet to electric, one of the first tangible policies towards the state’s goal of reaching zero net emissions by 2050. In September 2019. ACT also released the results of its 12 month trial of electric buses, part of its broader goal to switch to zero-emissions vehicles, which showed that zero-emissions vehicles “are a viable alternative for Canberra’s public transport network going forward”. Around a similar timeframe, BYD also announced it will supply its electric bus chassis for the Australian bodymaker Volgren, the largest in Australia.
E-buses technology and infrastructure
E-buses technology has developed rapidly in the last few years to address issues such as limited range and long battery charging times, which made reliance on electric buses for large scale public transport impossible just a few years ago.
E-buses form a big part of the future solution for urban sustainable mobility, but cities need new infrastructure to support this transition. These include hardware such as charging stations at redesigned bus depots and other equipment, and operating systems for battery life-cycle monitoring, range calculations and charging management.
Evenergi consulting for e-buses
Evenergi has developed a solution that helps bus operators to seize the opportunities and manage the risks of an eMobility future. The solution provides development of economic and technical models to support the migration to electric buses, using Evenergi’s EVsim™ model to emulate your e-bus network to assess the impact of e-bus charging on peak electrical demand, support the selection of potential bus suppliers, help understand the bus market dynamics and support grant opportunities and submissions.
