The government will fund the design of a scheme to install overhead electric cables to power electric lorries on a motorway near Scunthorpe, as part of a series of studies on how to decarbonise road freight.
The electric road system – or e-highway – study, backed with £2m of funding, will draw up plans to install overhead cables on a 20km (12.4 miles) stretch of the M180 near Scunthorpe, in Lincolnshire. If the designs are accepted and building work is funded the trucks could be on the road by 2024.
Road freight is one of the hardest parts of the economy to decarbonise, because no technology exists yet on a large scale that is capable of powering long-haul lorries with zero direct exhaust emissions.
New diesel and petrol lorries will be banned in Britain by 2040 as part of plans to reduce carbon emissions to net zero by 2050. That has given lorry companies little time to develop and commercialise technology that will be crucial to the functioning of the economy. While cars can rely on lithium ion batteries, the weight of a battery required to power a fully laden truck over long distances has prompted trucking companies to look for alternatives.
The e-highway study is one of several options that will be funded, along with a study of hydrogen fuel cell trucks and battery electric lorries, the Department for Transport said on Tuesday.

More than 50 years ago hydrogen fuel cells helped put Neil Armstrong on the moon, but mainstream usage of the technology has remained elusive since.
Now there are signs that may be changing, with a spate of new investments even amid the coronavirus pandemic.
In the UK, the transport secretary, Grant Shapps, this week told MPs that the government will experiment with hydrogen fuel cells for an entire town’s bus network. Earlier this month, the Department for Transport gave £400,000 to the Hydroflex project, run by the University of Birmingham and rail-leasing company Porterbrook, to bring the first hydrogen train to UK main lines in the next few weeks.
Fuel cells function by running hydrogen over a catalyst, often platinum, stripping away electrons that run through an electrical circuit. The positively charged hydrogen ions combine with oxygen in the air to form water as its only emission, while the electricity generated can run the same motors as used in any electric vehicle, giving a fuel source with zero harmful exhaust emissions.
Crucially, the hydrogen must be produced from clean sources to be carbon neutral, or “green”. So-called blue hydrogen, created using methane gas rather than electrolysis of water, has attracted significant interest from fossil fuel producers, but it does not come with the same environmental benefits.
