Compact Electric Hydrogen Booster for Decentralised Refuelling and Mobility Applications

Hydros Power S.L., an award-winning Spanish SME specialised in hydrogen technologies, offers the STELION® Booster Station, a compact and fully electric hydrogen compression unit designed to enable decentralised hydrogen refuelling and on-site gas handling wherever conventional infrastructure is impractical, costly or unavailable.

One of the main bottlenecks in the hydrogen value chain is the high cost and complexity of traditional refuelling stations. Conventional solutions rely on large compressors, high-pressure installations, cooling systems and significant CAPEX, which makes small-scale, pilot or distributed hydrogen deployment economically unviable.

The STELION® Booster Station directly addresses this challenge by providing a plug-and-play, electric-driven compression solution that can be deployed close to the point of use.

Key features:

• Fully electric operation: no compressed air, no external hydraulic drives.

• Adjustable pressure range: inlet pressures from low pressure up to 200 bar (model dependent) and outlet pressure up to 350 bar.

• Compact and mobile design: suitable for laboratories, workshops, industrial sites, mobility hubs or remote environments.

• Fast refuelling capability, reducing downtime for hydrogen-powered equipment or vehicles.

• Explosion-proof architecture, designed specifically for hydrogen, with stainless steel components and triple-seal systems.

• Low noise level (~63 dB) and low power consumption (~1.2 kW).

• User-friendly digital interface for safe and intuitive operation in the field.

• Long operational lifetime (up to 3,500 operating hours).

The system is compatible with hydrogen and other industrial gases, making it suitable for a wide range of applications, including:

• Hydrogen mobility and refuelling for small fleets or pilot projects

• Industrial hydrogen processes

• Laboratories and testing facilities

• Logistics hubs and depots

• Remote or off-grid energy systems

• UAVs, USVs and other weight- or space-constrained hydrogen applications

The STELION® Booster Station enables true decentralisation of hydrogen use, allowing users to compress and refill hydrogen where and when it is needed, without dependency on large refuelling stations.

At Hydros Power, we are seeking commercial partners, system integrators, distributors and industrial end users under a Commercial Agreement with Technical Assistance. The company provides the equipment together with technical support, system configuration, training and assistance to adapt the solution to local regulations and operational requirements.

This cooperation model ensures safe and efficient deployment of the technology while allowing partners to expand their hydrogen offerings with a proven, field-ready solution.

The STELION® Booster Station is already on the market and ready for international deployment, supporting the transition towards flexible, scalable and decentralised green hydrogen infrastructure.
