Regionalbus Rostock (REBUS) – mobility with green hydrogen In October 2024, the municipal transport company REBUS put the first of a total of 52 hydrogen buses into operation, which will operate emission-free in local public transport. In future, we will supply the buses with 2,200 tons of green hydrogen and have taken over the planning, construction, operation and maintenance of the filling stations.
Objective: Reduction of emissions in local public transport
In order to meet the wishes of its own customers for more sustainability in public bus transport, REBUS is gradually converting its own fleet to hydrogen buses. In future, a third of the entire fleet is to be emission-free. The company was looking for a partner with whom it could successfully implement the drive transition.
H2APEX takes over hydrogen supply and the construction of 2 filling stations
The company relied heavily on H2APEX’s expertise for the drive turnaround. As a system integrator for hydrogen solutions and producer of green hydrogen, we were awarded the contract for the planning, construction, operation and maintenance of two hydrogen filling stations in spring 2023. We were also entrusted with supplying the two filling stations with green hydrogen.
The project data:
- Construction of 2 hydrogen filling stations at the REBUS depots in Güstrow & Bad Doberan
- Supplying the fleet with 300.000 kg of green hydrogen per year
By supplying hydrogen as a clean fuel, H2APEX not only supports the transition to greener transportation solutions, but also helps to improve air quality in urban areas and reduce the carbon footprint of urban transport.
Successful project completion in October 2024
The construction of the first hydrogen filling station in Güstrow was successfully completed in October. The hydrogen filling station in Bad Doberan will be ready for operation by the end of the year. Similar to a diesel drive, a refueling process takes an average of 10 minutes.
H2APEX produces the green hydrogen in accordance with RED II for supplying the fleet and filling stations in its own 2 MW hydrogen electrolysis plant at the company’s Rostock-Laage site. In order to be able to provide the required volume for REBUS, additional storage capacities for approx. 400 kg of hydrogen were built for optimized plant operation and the filling and logistics capacity for transporting the hydrogen to the filling stations was increased.
The green hydrogen produced by H2APEX is generated exclusively from renewable energies such as wind and solar power.

With H2APEX, we are currently creating the infrastructure for the use of green hydrogen for our local transportation. We have come to know and appreciate H2APEX as a reliable partner and specialist for green hydrogen.
Project data
H2 Quantity:
The project can produce 300,000 kilograms of hydrogen per year. This is the amount of hydrogen needed to supply the regional buses and significantly reduces the environmental impact of fossil fuels.
Mobile storage:
H2APEX has developed its own mobile storage solutions that enable flexible and efficient refueling of buses on the road.
Stationary storage:
The stationary storage capacity of 2,347 kg ensures that a sufficient quantity of hydrogen is available at all times to meet demand. In this way, gaps in supply can be avoided and a reliable planning basis is created for the bus companies.
For comparison: a typical hydrogen bus requires around 10 kg of hydrogen for 100 km. With 2,347 kg of hydrogen, around 235 buses could be refueled for a distance of 100 km.
Refueling:
Approx. 10 minutes per bus at 25 kg. The hydrogen filling station is capable of refueling 52 buses in 16 hours. Refueling takes place via a mobile hydrogen trailer.
Information:
H2Apex has been operating the first hydrogen filling station for heavy goods vehicles in Mecklenburg-Vorpommern since 2022. This enables trucks, buses and cars to be refueled with climate-neutral hydrogen.
Space requirement:
80-100 m²
Hydrogen quality at the pump:
ISO 14687 / DIN EN 17124
CO2 reduction:
2 million kg per year
