Electrified roads The road to fossil free transportation 2017 Commercial Road Transport Symposium, Malmö 2017-10-12 Hans Säll, CEO eRoadArlanda and Head of Business Development at NCC 1
eRoadArlanda • A pre-commercial procurement • In June 2015, it was decided that process was initiated in June two of the eleven consortiums will 2013 – the largest yet in Europe – electrify existing public roads: by the Swedish Transport eRoadArlanda and Gävle Electric Administration, VINNOVA and the Road. Swedish Energy Agency.

Global CO 2 emissions 1/3 from heavy vehicles 2/3 from cars
Gasoline vs. electricity in Sweden • Motor output (efficiency): • Cost of running a car (without taxes) – Gasoline = 6 SEK = 100 % – Gasoline = 30% – Electricity = 25 % – Electricity = 85% – Difference = 75 %
Three steps to achieve fossil-fuel-free transportation 2 1 3 2015-12-11 eRoadArlanda
A bit of history • • The world’s first Porsche, in 1898, was At the same time, a system for leasing and battery replacement was introduced. battery powered • Up until 1916, the U.S. dominated in electric cars • The first hybrid car was built in 1900
The world’s first “e - bus” • Tested in Berlin in 1882 and manufactured by Siemens • Today, there are more than 350 different trolley-bus systems in the world 2015-12-11 eRoadArlanda
472m Impact on society costs 325 m If all cars in Sweden were a Tesla: = 2 miljoner m3 batteries If all heavy vehicles is equipped with 4 h electrical driving power = 0,2 miljoner m3 batteries 47 m Significant cost and environmental savings! If passenger cars can use the technique for electrified roads. 11

The solution In Sweden it would be sufficient to electrify 20 000 km of totally almost Direct feed 500 000 km roadways at a cost of about 10 - 15 BnEUR Battery Sweden are importing fossil fuel amounting to 6 BnEUR every year 45 km
Charging while driving Conductive technology – feeding from above
Charging while driving Inductive technology – feeding from the road
Charging while driving Conductive feeding from the road- Our choice
Conductive technology with feeding from the road • Vehicles are charged and operated while driving • Works for all types of vehicles • Existing infrastructure can be used • Can reduce CO ₂ emissions by 80-90% • Batteries can be reduced to less than 50 km range. • Cost is expected to come down to less than one MEUR/km
Fossile versus electric road - Low traffic intensity 2 200 vehicles per day Cost in thousand EUR per km and year 33 45 11 Cost of truck and car fuel Cost of electricity for trucks and cars Cost of electric road 20

How the rail are layed down into the road Target in full production: 1 km per hour 25
The Truck • Brand: DAF • Converted by: E-traction • Engine, power train and diesel tank removed. • Two motors built into the rear axle. Total power of 226 kilowatts (300 hp). • Battery: 80 kWh, weight 600 kilos. • Weight: 18 tons • Load: 6.5 tons • Emissions: Zero • Driving characteristics: Quiet, better acceleration and stable with low center of gravity
Test track at Arlanda • A 200-meter test track was built in May 2012. • Additional 150 meters in October 2014. • The first 200 meters were replaced by version 3 in August 2016. • Additional 50 meter version 4 was installed in March 2017.
Some challenges • Construction of rail has been changed during the project. • Almost everything we do is about starting from scratch. • New technology in a public road = a lot of anxiety and tough demands. • No existing industrial production of rails. • No standards, not even similar standards. • The choice of a fully electric truck has been a long and bureaucratic process. 28
Ongoing and coming activities • Electrifying 2 km between Arlanda Airport and Rosersberg Freight Terminal • Civil works beside the road (cables etc.) have been finalized in September 2017. • Ongoing production of rails. • Focusing on safety and system verification. • Waiting for ”GO” to start mounting the rails into the road. • Commercial transports started in September 2017 • Increasing number of visits and presentations 29
