Suzuki Motor Corporation has showcased a range of alternative-fuel technologies at the Tokyo Motor Show, underlining that the road to a carbon-neutral future cannot rely on a single propulsion system. On display is a prototype of the Access that will run on CBG (compressed biomethane gas) and CNG (compressed natural gas), as well as the hydrogen-powered Burgman.

2. India-based biogas project turns dairy waste into CBG

Suzuki’s India-focused biogas project

Suzuki showcases a scale model of the biogas plant located in India.

Among the highlights is an energy and fertiliser project developed with a dairy cooperative in India. The initiative converts dairy waste into compressed biogas, which is a renewable energy source. A scale model of the biogas plant is on display, outlining how localised energy production could support rural economies while reducing emissions.

Also on display is the R&D version of the Access scooter powered by CNG and CBG, featuring dual tanks for petrol and gas fuels – a layout not yet seen in production scooters. In terms of design, the Access CNG/CBG prototype looks identical to the model sold in India, but lifting the seat reveals a 6-litre CNG tank with a filling nozzle beneath it, along with a 2-litre petrol tank that can be refilled via an external fuel filler. With all propulsion sources topped up, the scooter offers an estimated range of around 170km, though the additional hardware increases the Access’s overall weight by about 10 percent.

Additionally, Suzuki is exhibiting a hydrogen-powered concept based on the Burgman 400 scooter, marking the latest step in the company’s hydrogen engine development. Cutaway models illustrate how the prototype has evolved since it was first shown at the 2023 Japan Mobility Show.

Together, these exhibits reflect Suzuki’s multi-pathway approach to achieving carbon neutrality – combining biogas utilisation, low-carbon fuels and hydrogen combustion research to explore practical solutions suited to different markets and applications.
