Heat that works wherever you do
Bus Heating System
A reliable bus heating system is essential to protect batteries and critical onboard components during cold nights. As fleets shift to electric and hydrogen buses, they need an efficient, emission-free way to maintain safe temperatures. Our hydrogen-powered solution delivers exactly that — clean, dependable heat that works anywhere without diesel or grid connections.
Passenger Convenience
In cold climates, buses must stay above freezing through the night to protect batteries, electronics, and onboard systems. Today, most fleets rely on diesel heaters or grid-connected electric solutions at depots.
These systems are costly, emission-heavy, and tied to stationary infrastructure. As fleets transition to electric and hydrogen buses, operators face a pressing challenge: how to heat vehicles efficiently, cleanly, and independently without relying on outdated diesel burners or expensive depot power upgrades.
A Smarter Way to Keep Bus Fleets Warm
A public transport operator manages hundreds of buses parked outdoors or in partially insulated depots. Each night, the fleet must stay warm to ensure morning readiness. Diesel heaters create noise and emissions, while electric heating puts heavy load on the grid — often requiring costly upgrades.
For operators with remote or satellite depots, installing high-power electrical connections is impractical. The need is clear: a heating solution that is mobile, reliable, and future-proof.
The result? Coverage gaps, missed events, and teams stretched thin trying to keep equipment alive instead of focusing on security.
Motivations to Change
- CO₂ rules and zero-emission targets are phasing out diesel heating.
- Electric buses need stable heat to protect battery health.
- Operators must cut emissions and operating costs without new depot infrastructure.
- Flexible parking and heating locations are increasingly important.
Solutions provided by our technology
Lamina® fuel cells provide a clean, grid-independent heating solution by generating heat and electricity in one compact unit.
The system stays dormant when not needed and activates automatically for overnight heating, making it highly reliable and low-maintenance. With modular hydrogen bottles placed beside the unit, operators get a simple, high-energy “place-and-forget” setup that works anywhere — even in remote or temporary depots.
As hydrogen refueling infrastructure grows, the system becomes even easier to integrate into modern fleet operations.

Frequently Asked Questions (FAQ)
With modular hydrogen bottles, the system can run through the entire overnight parking period, delivering consistent heat and auxiliary power without interruption. Runtime scales with the number of hydrogen cylinders used.
Hydrogen bottles are simply swapped on-site — a process that takes under 2 minutes. No fixed hydrogen station or depot infrastructure is required.
A hydrogen cylinder swap takes under 2 minutes. In contrast, battery recharging takes 4–8 hours, or requires carrying heavy spare packs into the field.
The Lamina® fuel cell module is compact and lightweight, and the hydrogen bottles can be positioned next to the bus or heater. This allows deployment in remote parking lots, overflow depots, or temporary fleet areas without electrical installations.
Yes. Lamina® provides combined heat and power (CHP). It warms the bus interior or batteries through existing heating circuits and simultaneously supplies electricity to onboard systems or auxiliary heaters.
The fuel cell remains dormant when not needed and starts automatically based on temperature demand. This makes it ideal for reliable, independent overnight heating with minimal operator involvement.
Very little. Lamina® fuel cell units require minimal servicing, especially compared to diesel heaters or electrical systems that rely on high-power infrastructure.
