The Volgren Zero Emission Journey
Leading Australia to
zero emissions.
From Australia’s first Optimus electric bus in 2019 to more than 600 zero-emission buses in service by the end of 2026 — no Australian manufacturer has built more, deployed more, or supported more.

The journey so far
Milestones on the road to zero
2019
Volgren unveils Australia’s first Optimus battery-electric bus, launching the lightweight Co-Bolt® aluminium body into the zero-emission era.
2021
Volgren expands into hydrogen, delivering its first fuel-cell electric buses and proving the Optimus platform across both battery and hydrogen propulsion.
2023
Zero-emission Volgren buses enter service with government agencies and operators in every mainland state, across six chassis platforms.
2025
A record year: more than 150 battery-electric buses built across Volgren’s facilities, alongside Queensland’s 2,000th locally built bus.
2026
Over 600 zero-emission Volgren-bodied buses expected in service nationally — including Australia’s first electric articulated bus for PTA WA.
The impact
What zero emission leadership delivers
Every diesel bus replaced by a Volgren-bodied ZEB takes real carbon out of Australia’s cities — and keeps the manufacturing jobs behind it onshore.
*Estimate: ~78 t CO₂ per urban diesel bus replaced, per year. Actual savings vary by route, duty cycle and grid mix.
National presence
Proven in every mainland state
Battery-electric and hydrogen Volgren buses in daily service with government agencies and operators across the country — one of the lightest electric bus bodies in its class, chassis-agnostic by design.
