15% of Sweden’s carbon dioxide emissions are from freight trucks. And, to make transport more sustainable, the eHighway , an electric highway, was born.
In this way, heavy vehicles that circulate on this type of highway will be able to feed on the electricity network thanks to a catenary system , similar to that used on train tracks. eHighway has just been opened on a 2-kilometer stretch of the E16 motorway, north of Stockholm.
According to Roland Edel , chief engineer of the mobility department at Siemens, the German company in charge of the project:
The eHighway is twice as efficient as conventional internal combustion engines. (Our) innovation consists of feeding the trucks with the energy that comes from the (electrical) lines.
While these vehicles are being powered by electricity, they do not emit carbon dioxide and are 80% efficient . And every time the driver brakes, he feeds the electrical grid with the kinetic energy that is released.
