UK trial of electric cars proves they are greener

Experts leading a major three-year trial into the impact of electric vehicles and the role they could play in our transport systems of the future, have shown that rolling them out across our city’s roads would protect both our health and the environment.

Data gathered and analysed by transport experts at the UK’s 5986 Newcastle University shows that daytime air pollution levels in our towns and cities regularly exceed the Government’s recommended 40µg m-3 (21 parts per billion) for prolonged periods, putting people’s health at risk.

Now the SwitchEV study, the first of its kind in the UK, has shown that not only could electric vehicles reduce transport-related pollution in our cities, they also produce less CO2 per km than a combustion engine, even when the pollution associated with electricity generation at power stations is taken into account.

Funded by the UK’s innovation agency, the 2231 Technology Strategy Board, the three-year investigation is part of a major US$16.7 million trial investigating the impact that electric vehicles could have on the environment, our transport systems and driver behaviour.

Using in-vehicle loggers, details such as distance travelled, route, driving behaviour and re-charging times have been recorded and analysed for over 71,600 electric vehicle journeys and 19,900 re-charging events.

The team found that for all the electric vehicles in the study, their carbon efficiency was better than an equivalent internal combustion (IC) engine vehicle. Charging during off-peak times, when less carbon intensive and renewable energy sources are being used to power the grid, together with more efficient driver behaviour would reduce this carbon output even further.

And because electric vehicles produce zero exhaust gases, introducing more of them to our cities’ roads would drive down pollution in the most congested, and often highly populated, areas, such as city centres and around schools.

Presenting their findings, the team led by Future Transport Systems and Newcastle University together with 838 Nissan, Avid Vehicles, Simon Bailes Peugeot, Smith Electric Vehicles and 5322 Liberty Electric Cars, say the study has proved that electric vehicles are set to play a key role in our transport systems of the future.

Pollution levels in Newcastle were analysed using data from the air pollution monitoring station outside Newcastle Civic Centre.

The Newcastle University team has now received funding to continue the SwitchEV project for a further year and will explore how CO2 emissions can be reduced still further, charging at off peak times through the Smart Grid project.

    New services and equipment helps cities tackle air quality issues
    With poor urban air quality shortening lives and fines being imposed for breaching pollution limits, authorities are seeking ways to clean up their cities. Poor air quality is topping the agenda for city authorities across the globe. In the UK, for example, a report from the Royal Colleges of Physicians and of Paediatrics and Child Health, concluded that poor outdoor air quality shortens the lives of around 40,000 people a year – principally by undermining the health of people with heart and/or lung prob

    VW and Shell try to block EU push for electric cars
    VW and Shell have united to try to block Europe’s push for electric cars and more efficient cars, saying biofuels should be at heart of efforts to green the industry instead. The EU is planning two new fuel efficiency targets for 2025 and 2030 to help meet promises made at the Paris climate summit last December. But executives from the two organisations launched a study on Wednesday night proposing greater use of biofuels, CO2 car labelling, and the EU’s emissions trading system (ETS) instead.

    Are truck bans the wrong move in the battle for air quality
    Low emission zones and heavy goods vehicles’ access to city centres may at first glance appear attractive but how effective are such controls? Jon Masters reviews emerging trends across Europe. Around 1,700 European cities have implemented low emission zones (LEZs) and in addition some have restricted city centre access for heavy goods vehicles (HGVs). Even those that restrict HGV access, such as Paris and Rome, allow exemptions at certain times and for particular classes of vehicle. But with what effect?

    Liberty Electric Cars has been selected to become one of the major partners of the project thanks to its extensive experience in electric commercial vehicle engineering and design. Its team of experts played a crucial role in the development of the Modec truck, a range of 5.5t commercial vehicles that have been sold to a wide variety of customers across Europe. Operators of the Modec truck include global companies like FedEx, UPS, Tesco’s and Veolia. Their unique team of engineers have created EVs that have
