Following the delivery of the bus fleet and the securing of a green hydrogen supply, Weser-Ems-Bus has commissioned a mobile hydrogen refuelling station in Lower Saxony, enabling the rapid deployment of its hydrogen buses while awaiting the completion of a permanent refuelling station.

A mobile station: a practical answer to a major operational challenge

As many local authorities transition their fleets to hydrogen mobility, synchronising the deployment schedules of vehicles, refuelling infrastructure and associated equipment can prove challenging. Mobile refuelling stations provide an immediately available solution to secure the start-up phase of hydrogen mobility projects. 

Partners join forces to accelerate the deployment of a hydrogen bus fleet

In December 2025, Weser-Ems-Bus, a subsidiary of DB Regio AG, deployed six fuel cell buses to provide regular public transport services from Jever in the East Frisia region of Lower Saxony. The project was developed in close collaboration with the Friesland district, the authority responsible for public transport. 

Pending completion of the permanent hydrogen refuelling station, Weser-Ems-Bus quickly established a partnership with the independent research institute Technologie-Transfer-Zentrum Bremerhaven (ttz Bremerhaven), station operator MoviaTec and green hydrogen producer and supplier Lhyfe.

-  ttz Bremerhaven provided its own mobile refuelling station and is carrying out scientific monitoring of the buses’ deployment, allowing the institute to collect valuable operational data and insights on the performance of hydrogen buses in daily service. 

-  MoviaTec operates the entire refuelling station at the Jever site and ensures safe and reliable operation in line with applicable safety requirements. Its role includes preparing the explosion protection documentation, coordinating regular visual inspections and operational checks, and supporting commissioning as well as the resolution of technical challenges during operation.

-  Lhyfe supplies RFNBO^]-certified and green hydrogen, meeting the highest sustainability requirements currently defined by the European Union. With four RFNBO-certified green hydrogen production sites, a fleet of more than 80 Type IV hydrogen containers – one of the largest and most modern bulk hydrogen transport fleets in Europe – and around fifteen storage locations, Lhyfe is one of Europe’s pioneering producers and suppliers of green hydrogen. 

This solution enabled Weser-Ems-Bus to immediately launch its fleet in December 2025, and to ensure a continuous supply of green hydrogen in line with its sustainability commitments.

Faster-than-expected refuelling: a practical and replicable solution 

The mobile refuelling station operates at 350 bar, the pressure level commonly used for hydrogen-powered buses and commercial vehicles.

Before the station came on line, several refuelling scenarios were modelled based on the anticipated hydrogen demand of the buses. These assumptions are now being validated under real operating conditions. Actual refuelling operations have shown that buses can be refuelled more quickly than anticipated in the original simulations. As a result, the station has met — and in some cases exceeded — the expectations of the project partners.

This project demonstrates that vehicle deployment and infrastructure commissioning do not necessarily need to follow the same timeline, offering a practical solution to accelerate the transition to zero-emission public transport.

The next steps will focus on further optimising refuelling operations and analysing vehicle consumption data until the permanent station in Schortens, within the JadeWeserPark industrial area, enters service later in 2026.

Daniel Marx, Managing Director, Weser-Ems-Bus, a subsidiary of DB Regio AG: “We are actively shaping the future of mobility and take our responsibility for climate protection seriously. With the help of funding from the Federal Ministry of Transport, around 10% of DB Regio Bus Nord's fleet runs emissions-free, mostly on battery-electric. In close cooperation with the Friesland district, we were able to test the use case of hydrogen mobility and gained important experience for the future.”

Günther Schumacher, Project manager, ttz Bremerhaven: “From our previous projects, we are familiar with the challenges involved in introducing hydrogen buses. By analysing the routes and the needs of the bus operator, we were able to develop suitable scenarios for on-demand refuelling of the hydrogen buses introduced in Jever and to implement our hydrogen refuelling system there. Under everyday operating conditions, the refuelling station worked very well and has even exceeded expectations.”

Frank Rößler, Managing Director of MoviaTec GmbH: “This project demonstrates that hydrogen mobility can be implemented quickly and reliably when infrastructure, supply and operation are closely coordinated. As operator of the mobile refuelling station, MoviaTec ensures safe day-to-day operation and supports the project with its practical experience in hydrogen infrastructure, commissioning and technical operations.”

Pascal Louvet, Sales Director Germany at Lhyfe: “Across Europe, we are seeing increasing maturity within hydrogen mobility ecosystems and a strong determination to accelerate deployment. The technologies are available, initial use cases are proving successful, and local stakeholders are progressively organising around operational projects. The challenge today is to enable these projects to move forward quickly through efficient solutions adapted to real-world conditions. Mobile refuelling stations really hit this nail on the head.”

Containerized battery energy storage systems (BESS) have expanded rapidly in North America as utilities, businesses, and communities integrate batteries for grid stability, backup power, renewable energy integration, microgrid support, and hybrid energy systems. 

This widespread adoption is one reason safety standards such as NFPA 855 have become more significant, as regulators and industry stakeholders seek consistent guidelines for safely installing and operating the expanding number of battery energy storage systems.

The National Fire Protection Association Standard 855, formally titled “Standard for the Installation of Stationary Energy Storage Systems,” is the primary fire-safety and installation standard in the United States for BESS and other stationary energy storage technologies. The document establishes minimum safety requirements governing how these systems must be designed, installed, operated, and protected in residential, commercial, and utility-scale settings.

The standard exists because large battery installations introduce unique hazards, particularly with lithium-ion batteries, including thermal runaway, flammable gas generation, and potential fire propagation between battery modules or containers.

NFPA 855 addresses these hazards by requiring a “layers of protection” approach to hazard mitigation and fire protection. Rather than relying on a single safeguard, the standard expects systems to incorporate several independent protections that collectively reduce the likelihood and severity of failures. 

In practice, this means installations typically include combinations of monitoring, detection, containment, and suppression measures. These can involve early fire detection, gas detection, ventilation to address buildup of flammable gases, fire-suppression systems, explosion prevention and control, and design features intended to prevent or limit thermal runaway propagation between battery cells or modules.

Containerized BESS

The use of standardized container formats has become the dominant architecture in large scale battery storage because it simplifies manufacturing, transportation, and installation. It also allows systems to be scaled easily by adding additional containers to meet the desired energy demand. 

This approach allows manufacturers to package batteries, cooling systems, power electronics, and safety equipment into a modular unit that can be transported by truck, rail, or ship and installed quickly at a site.

However, most utility-scale battery projects do not consist of just one container. Instead, many containerized units are deployed together in rows across a site, connected through power conversion systems and transformers to form a much larger energy storage plant. 

A single project might include dozens or even hundreds of containers arranged in arrays. The combined capacity of these installations can range from tens of megawatt-hours for small grid support projects to hundreds or even thousands of megawatt-hours at the largest facilities.

Hydrogen Accumulation

According to Geof Brazier, Managing Director of BS&B Safety Systems Explosion Protection Division, in the most recent 2026 edition of NFPA 855, several new requirements were introduced related to battery system hazards and protection strategies, including expanded hazard-mitigation analysis, additional testing expectations, and stronger provisions related to fire and explosion risk management in large battery installations.

“One of the recognized safety concerns was the buildup of hydrogen and other combustible gases in containerized BESS, because hydrogen is highly flammable and can accumulate to a combustible concentration in enclosed spaces if not properly ventilated or monitored and controlled,” says Brazier.

Hydrogen rich gas can be generated during certain battery failure modes or abnormal operating conditions. In some battery chemistries, even traditional lead-acid batteries, hydrogen is produced as a normal byproduct during charging through electrolysis of water in the electrolyte and typically in small, easily ventilated quantities.

In BESS installations that use lithium-ion batteries, hydrogen and other combustible gases can be generated during thermal runaway or internal battery damage. When lithium-ion cells overheat or fail, chemical decomposition of the electrolyte and other cell components can produce a mixture of gases that may include hydrogen, carbon monoxide, methane, and other flammable compounds. 

The danger arises when hydrogen or other flammable gases accumulate in an enclosed space and are then ignited by electrical equipment, static discharge, or other ignition sources. 

Hydrogen has a very wide flammability range and a low minimum ignition energy. In air under typical conditions, it is flammable at concentrations of approximately 4% to 75% by volume; the lower end of this range, about 4%, is known as the lower flammability limit. Because it is lighter than air, hydrogen tends to accumulate near the ceiling or the upper portions of a container if ventilation is inadequate. This can further increase hydrogen concentrations in those upper areas.

In the lower ranges when hydrogen comprises less than 20% of the mixture in air by volume, an ignition can cause a deflagration event.

Unlike a detonation, which produces a supersonic shock wave of great destructive force, a deflagration is slower moving but still produces unacceptably high pressures in a confined structure. The expanding combustion gases press outward rapidly at high temperature and pressure and, if not intentionally relieved, the structure can suffer significant damage, and occupants or nearby individuals may be seriously injured. 

When the percentage of hydrogen in the air is around 20%, detonation events can generate powerful shock waves that travel faster than the speed of sound. 

“When you get into the higher percentages, you are dealing with explosions that can transition to an unprotectable detonation, so it is important to do the utmost to reduce the level of hydrogen accumulation in the container so the conditions for an explosion do not arise,” says Brazier. 

The resulting deflagration or explosion may not only damage the container but may propagate fire driven overheating to adjacent BESS modules.

Because of these risks, Brazier says modern BESS designs emphasize early detection and layered protection strategies. These include monitoring battery temperature and voltage to detect failures early, detecting flammable gases before they reach hazardous concentrations, and providing controlled ventilation or explosion relief to prevent pressure buildup.

BS&B Safety Systems’ VSP Actuated Ventilation System is an NFPA 69 explosion prevention device designed to protect BESS enclosures by actively releasing combustible hydrogen and other accumulated gases before an explosive concentration arises.

Sensors continuously monitor combustible gas concentrations inside the enclosure. When elevated gas levels are detected, an actuator opens the vent flap to safely discharge the gases. Once concentrations return to acceptable levels, the actuator closes the flap, and normal operating conditions are restored. This automated cycle repeats as needed whenever elevated gas levels are detected, providing continuous protection for the enclosure.

“An explosion prevention device doesn’t necessarily have to respond to an explosion,” explains Brazier. “In this case, it responds before an explosion would occur to let the hydrogen out before it builds up into a combustible range.”

Containerized BESS are also increasingly fitted with explosion vents to control the pressure spikes and direct flame and gas when a thermal-runaway event causes a flammable atmosphere to ignite and a low concentration of combustible gas results in a deflagration. 

Brazier says BS&B specifically designed its BESS-Saf™ as a family of explosion and pressure relief vents with BESS enclosure dynamics in mind. The vents support controlled pressure relief to help mitigate explosion risk resulting from thermal runaway and gas generation.

The low-burst-pressure explosion vent panels can be mounted on the container roof or upper exterior walls. In the event of a deflagration or explosion, the panel opens and vents to the open atmosphere, directing the discharge away with attention to avoidance of discharge across egress paths being essential.

The BS&B explosion vent type VSP-A is a breathable construction that permits combustible gases to pass through the device under normal operating conditions while providing a barrier from rain, snow and other climatic influences. 

Flame-Free versions incorporate a flame arrester rated for hydrogen and other gas deflagration conditions with an explosion vent. This combination provides a reliable layer of protection for enclosures exposed to deflagration and overpressure risks. 

“If hydrogen or other gases accumulate and a deflagration arises, the explosion vent opens to relieve overpressure while the integrated flame arrester quenches the flame front to mitigate the release of flame to the atmosphere,” says Brazier.

Pressure relief vents of this kind are often combined with gas detection and forced ventilation systems to keep concentrations below the lower flammable limit. 

“Explosion venting is not mandatory [in NFPA 855], but it is one of the permitted methods for achieving explosion control,” explains Brazier. “Because venting is often a comparatively economical solution, it receives significant attention and is frequently viewed as the preferred cost-effective approach.”

According to Brazier, vent selection is determined through an evaluation of the enclosure’s size and structural capacity, the design strength, and the total vent area necessary to maintain internal forces within allowable limits. 

Companies like BS&B Safety Systems are able to provide technical guidance throughout the specification process to help identify the appropriate explosion vent configurations, and materials to support an effective venting strategy aligned with applicable codes and standards. 

“By working methodically through these parameters, the correct design approach can be established with confidence, aligning performance, safety, and compliance objectives,” says Brazier.
