Gas tanks will be mounted on the bus’ roof while the equipment will inject the biomethane into the engine to create an optimal mixture of air and fuel.
The gas will be stored in the tanks in a gaseous state, as with current gas-operated buses and refilled in exactly the same manner from the same filling stations.
Volvo is participating in a demonstration project for gas/diesel technology using buses for regional traffic and trucks. Up to 70% of the fuel is biogas or natural gas. It is worth mentioning that many cities and regions are investing in expanding the production of biomethane for vehicle fuel.
