MAN's Frederik Zohm stresses the advantage of self-energy production: since energy accounts for one third of the operating costs in heavy-duty transport, the possibility of self-sufficiency reduces costs. Energy recovery plays an important role in eHDVs. Simulations show that up to 39% of energy can be recovered on the Bolzano-Innsbruck-Bolzano route. derstandard.de 🇩🇪
