Interesting article from CityLab on why plugging public transit EVs into a city can be more challenging and expensive than originally planned: https://www.citylab.com/transportation/2019/06/electric-bus-china-grid-ev-charging-infrastructure-battery/591655/ https://www.citylab.com/transportation/2019/06/electric-bus-...
"That’s what Philadelphia discovered when it decided to expand its existing fleet of e-buses with newer models—ones that featured bigger batteries. The city failed to recognize in the early planning process that it would be prohibitively expensive to acquire land in its busy downtown area for charging stations along the bus routes. So they decided to install all the charging infrastructure in the bus depots."
- wffurr 7y agoThe MBTA found that CNG buses had the lowest lifecycle cost and cost per greenhouse gas reduction. Diesel-electric hybrids have maintenance issues, and battery electric and hydrogen buses have significant capital costs which makes it difficult to realize the significantly lower operational costs. https://www.abettercity.org/docs/Alternative%20Propulsion%20Systems%20Final.pdf https://www.abettercity.org/docs/Alternative%20Propulsion%20... However, even pure diesel buses are much more efficient at moving people than single-occupancy vehicles. It's also worthwhile to note that a real plan for reducing greenhouse gas emissions would necessarily include substantial capital outlays: not just bus charging infrastructure but grade-separated rail, dedicated busways, bus rapid transit, cycle and scooter infrastructure, etc. etc. Not to mention all the other climate adaptions that need to happen at an infrastructure level.
