Sweden Vattenfall supports development of new technology for electrified roads.

The first electrified road in the world using an electric rail embedded in the tarmac enabling electric vehicles to be recharged while driven has been officially opened near Arlanda airport north of Stockholm. Vattenfall, the innovation company Elways and the construction and infrastructure company NCC are collaborating in this globally-unique development project, eRoadArlanda, on behalf of the state-owned Swedish Transport Administration.

Lena Erixon, the Swedish Transport Administration's director general, Tomas Eneroth, Sweden's Minister of Infrastructure, and Gunnar Asplund, the inventor of the electric rail, officially open the eRoadArlanda electric road.

The official opening ceremony for the electrified road was performed on 11 April by Tomas Eneroth, Sweden's Minister of infrastructure, Lena Erixon, the Swedish Transport Administration's director general, and Gunnar Asplund, the inventor of the patented electric rail, from Elways.

"Sweden is leading the way when it comes to development of electrified roads and is the first country in the world to have two public road test projects where electric vehicles can be recharged while driven, using either an electric rail in the tarmac or an overhead power line," says the Swedish Transport Administration's director general Lena Erixon.

Two electrified roads in Sweden
eRoadArlanda is the second electrified road project in Sweden to receive state funding stemming from the Swedish Transport Administration's innovation procurement initiative. The first project on a motorway between Gävle and Sandviken, 140 kilometres north of Stockholm, was officially opened two years ago. Here a number of hybrid trucks are charged using overhead power lines. The new patented Elways technology with an electric rail in the tarmac now enables all types of electric vehicles to recharge, not just only large lorries or buses. The investment cost per kilometre is estimated to be less than that of using overhead lines, as is the impact on the landscape.

A sliding pantograph fitted under the lorry takes up current from the electric rail. The pantograph can move laterally and is automatically flipped up from and down into the electric rail. The charge output is 200 kW.

"Vattenfall wants to contribute to the transition to electrified road transportation. Electrified roads that enable dynamic charging while driving can be an interesting solution not least in the case of heavier vehicles that need to travel longer distances without stopping to recharge. Expanding the electrified road network would also enable all types of electric vehicles to use smaller batteries and still have unlimited range," says Jesper Karpsen, Head of the Network Solutions business unit within Vattenfall Eldistribution.

Regular cargo traffic
The eRoadArlanda electrified road will now be tested for an extended period of at least 12 months under demanding road and weather conditions. The project's custom-built, fully-electric truck will transport goods during this period between the cargo terminal at Arlanda airport and PostNord's nearby logistics facility.

"Electrification of road networks is an important factor in reducing the total CO2 emissions in society. Carbon dioxide emissions from lorries account for about 25% of total road traffic emissions and the development of electrified roads can therefore be an important factor in reducing emissions from the transport sector," says Annika Ramsköld, Head of Sustainability at Vattenfall.
