EV bus outlook seems rosy
New Bloomberg report on the use and deployment of Electric Buses makes interesting reading.

Electric Buses in Cities– Driving Towards Cleaner Air and Lower CO2 at Bloomberg New Energy
Worth a read and lots of graphics to help paint the picture.
Few key points and charts below.
Air quality is a growing concern in many urban environments and has direct health impacts 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. 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.
The global e-bus market is changing quickly as cities make increasingly ambitious fleet electrification commitments. In October 2017, 13 cities signed the C40 Fossil- Fuel-Free Streets Declaration, pledging to procure only zero-emission buses from 2025 onwards.
The cumulative number of e-buses in Europe reached just over 2,100 units in 2017. Pure electric buses made up the majority of the total at 1,560 units. The U.K. has the largest e-bus fleet in Europe in absolute terms, but the share of e-buses in the total municipal bus fleet in the country was still below 1% in 2017.
E-bus charging configurations
There are three main types of infrastructure for charging electric buses: plug-in systems, inductive charging and conductive pantograph (overhead) charging (Table 3). Traditional plug-in charging is the most common and the cheapest charging system in use with e-buses today. It offers a range of charging rates, from slow to rapid and it is provided by a range of companies, including Heliox, APT, Siemens and ABB.
E-bus lithium-ion battery market review
The demand for lithium-ion batteries from electric vehicles – both e-buses and passenger EVs – is increasing. However, battery manufacturing capacity is increasing much faster than demand, which puts pressure on battery prices. As a result battery prices have fallen by 79% since 2010. The sensitivity of battery cycle and calendar life, and the challenges around predicting future battery life make warranties critical to e-buses. Since e-buses have only come to prominence in the last five years the true performance of their batteries may not yet be fully understood.
