Switching 10% of London’s current truck and van fleet from diesel to electric by 2021 could save the capital £900m in reduced health impact and abatement costs, researchers have calculated.
Such a move would also shave 402 tonnes of NOx, 3.8 tonnes of particulate matter and 284,000 tonnes of greenhouse gas from the capital’s streets (see box below).
The results were presented at the final Frevue conference last week (21 June) – a four-and-a-half year EU scheme to assess the viability of electric freight vehicles in towns and cities.
Three uptake scenarios for electric freight vehicles:
• Low – 10% of all freight traffic electrified
Low penetration level (10%), 2021:
High penetration level (100%), 2031:
Professor John Polak, director of the Urban System Laboratory at Imperial College London, undertook research to assess the environmental impact of electric trucks.
This included direct results from the Frevue vehicles taking part in the trial, traffic modelling to assess future impact depending on electric freight vehicle uptake levels, and the resulting cost savings to be realised.
Polak’s research also looked at the wider social impact and attitudes towards electric freight vehicles.
He surveyed hundreds of participants from the eight Frevue partner cities: Amsterdam, Lisbon, London, Madrid, Milan, Oslo, Rotterdam and Stockholm.
This included feedback from drivers and fleet managers, through to end customers and infrastructure providers. Some key conclusions found that:
- Drivers found electric vehicles to be a positive experience, enjoying the instant power, quietness and simple operation.
- Only 15% of drivers reported any range anxiety, which was due in the main to a low state of charge at the end of their delivery routes and a reduction in performance during cold weather.
- Fleet managers found the electric vehicles integrated easily into existing depot routines, with good reliability reported for electric vans and improved reliability for larger electric trucks after an initial trial and error period.
- Around half of logistics firms surveyed said they have committed to more electric freight vehicles in the short-term due to positive experiences, however, 30% said there is no plan as “better products are needed”.
- Others planned to deploy more electric vehicles as part of a wider fleet decarbonisation strategy, looking at suitability of all alternative fuels, infrastructure, financial incentives and policy.
