Nel Hydrogen Fueling Station by NEL ASA - compact solution for heavy transport

The Nel Hydrogen Fueling Station by NEL ASA stands behind a wire fence on a Norwegian depot yard, its white container humming softly while chilled hydrogen lines run to a sturdy dispenser island for buses and trucks. On a damp morning, droplets bead on the steel hoses as an operator lifts the heavy nozzle and clicks it into place. For Nel CEO Håkon Volldal, this compact station is a workhorse meant to serve fleet operators who need reliable hydrogen at scale.

Compact station for heavy vehicles

Nel’s Hydrogen Fueling Station is a modular, containerized hydrogen refueling solution designed primarily for buses, trucks and other heavy-duty vehicles, available in several standardized configurations. In its typical heavy-duty setup, the station can deliver up to about 1,000 kilograms of hydrogen per day at high-pressure standards such as 350 bar for buses and 700 bar for trucks. The system integrates compression, storage and dispensing equipment in one skid or container, allowing installation on fleet depots or public truck corridors rather than only large centralized hubs.

Depending on customer needs, Nel configures these stations as standalone units supplied by trailers, or connects them to on-site electrolysers from the company’s own Nel Hydrogen Electrolyser portfolio, creating a full production-and-fueling chain from renewable electricity to wheels. The dispensers are engineered to follow the relevant European and ISO standards for hydrogen fueling, including safety systems such as breakaway couplings, emergency stop switches and gas detection sensors. On site, operators handle the heavy hoses with gloved hands, feeling the slight vibration as hydrogen flows during a typical few-minute fill for a bus.

Standard configurations and performance

Nel describes its Hydrogen Fueling Station offering as a portfolio of standardized station packages, typically named according to capacity and pressure such as HD 1000 or similar internal designations. These systems are delivered with pre-engineered layouts that include compressors sized for the intended throughput, buffer storage banks, chiller units for pre-cooling and one or more dispensers. In practice, that means a bus operator can order a station tailored to a specific number of daily bus refills, rather than designing a custom solution from scratch.

To meet current European heavy-duty pilot projects, Nel’s fueling stations usually comply with regulations for hydrogen transport and workplace safety, integrating ATEX-certified equipment and observing zone classification rules. For larger corridor projects, the company can link multiple station modules to raise total daily capacity beyond 1,000 kilograms, though these layouts remain based on repeatable building blocks. In public tenders, Nel often teams up with partners like Nikola or regional energy utilities, with project managers such as Steffen Møller coordinating integration between the fueling station hardware and upstream green hydrogen production assets.

Customer use cases and markets

Fleet operators in Scandinavia, Germany and the US are early adopters of Nel’s Hydrogen Fueling Station, using it to support pilot fleets of hydrogen-powered buses and trucks. For example, in California and in German regions like Schleswig-Holstein, projects have installed Nel stations to refuel municipal buses, supplying them with compressed hydrogen within a few minutes per vehicle, comparable to conventional diesel refueling. The station’s footprint, typically a few standard containers plus a dispenser island, fits into existing depot yards where concrete pads and safety clearances can be laid out alongside parking rows.

In the US truck segment, Nel supplies fueling equipment for corridors involving manufacturers like Nikola, where heavy-duty trucks refuel at stations that must deliver consistent throughput and uptime. Here, Nel’s station design focuses on robust components and redundancy, with maintenance programs to keep compressors and chillers running consistently, something fleet managers feel directly when they walk past the humming station cabinets during a morning shift. The company positions these stations as a way to decarbonize heavy transport while keeping operational routines familiar to depot staff.

Integration with electrolysers and energy systems

A key part of Nel’s story is the integration between Nel Hydrogen Fueling Station units and Nel’s range of electrolysers, such as the alkaline series and PEM-based Nel Hydrogen electrolysers. In projects marketed as “hydrogen hubs” or “green corridors”, electrolysers convert renewable electricity into hydrogen on site, which is then compressed and sent to the fueling station’s storage banks. This arrangement reduces dependence on delivered hydrogen trailers and aligns with policy ambitions for local hydrogen production from wind or solar power in regions like Norway, Denmark or Germany.

Nel’s engineering teams design control systems so electrolyser production can match station demand, smoothing peaks when several buses arrive in sequence for refueling. In some publicized projects, digital monitoring dashboards allow operators to see real-time station status and hydrogen inventory, often installed inside small control rooms where staff watch screens while the hardware runs outside in the rain. CTO Sverre Gjønnes and colleagues have described this integration as central to Nel’s offering, tying equipment sales across both production and distribution segments of the hydrogen value chain.

Competitive landscape and technical challenges

The hydrogen fueling station market for heavy-duty vehicles features several players besides Nel, including companies such as Everfuel, Air Products and Linde, each supplying their own station designs. Nel’s Hydrogen Fueling Station competes on standardization and modularity, aiming to provide repeatable packages that can be scaled across multiple sites with relatively similar designs. Technical challenges remain significant, from ensuring reliable compressor performance to managing pre-cooling for high-pressure fills that keep nozzle temperatures within safe limits.

Another challenge lies in permitting and safety compliance, as hydrogen stations require adherence to national building codes, fire regulations and zoning rules, which can differ substantially between Norway, Germany, the US and other markets. Nel must work with local partners and authorities to certify each site, often sending field engineers like project manager Thomas Rønning to oversee installation and commissioning. That process includes pressure testing, leak checks and training sessions where operators handle hoses and emergency stop buttons, becoming familiar with the station’s tactile routines long before the first bus arrives.

Revenue significance and stock context

For NEL ASA, the Nel Hydrogen Fueling Station line contributes to the company’s Fueling division revenue, alongside related components and service contracts. While electrolysers remain a major business line, station deployments generate equipment sales as well as long-term service and maintenance income, particularly in multi-year public transport projects. Investors tracking NEL ASA stock watch how many fueling stations move from pilot stages into larger rollouts, because that shift can indicate more recurring revenue from hardware and services tied to heavy-duty transport fleets. On Xetra, the NEL ASA share trades in euro, reflecting how the company’s hydrogen infrastructure projects, including its Hydrogen Fueling Station portfolio, influence investor expectations around future growth in European and global hydrogen transport.
