Know the essentials
STELION Capsules are portable, plug & play hydrogen storage capsules developed by Hydros Power. They store compressed hydrogen in a compact, lightweight format designed for fast swapping and instant connection without the need for fixed refueling infrastructure, hoses, or cooling systems.
STELION hydrogen storage capsules come in three sizes. STELION Capsules S is designed for UAVs, AGVs, and portable systems. STELION Capsules M is built for last-mile delivery vehicles, trolleys, and small forklifts. STELION Capsules L is designed for reefer containers, off-grid generators, and backup power systems.
Refueling is based on a simple swap process. Empty capsules are exchanged for fully charged ones through STELION Distribution, a decentralized hydrogen delivery network. No on-site compression or cooling equipment is required.
Yes. STELION hydrogen storage capsules are fully compatible with the STELION ecosystem — including STELION Booster Station and STELION Powertrain — as well as third-party fuel cells, hydrogen systems, and external hydrogen sources.
STELION Capsules serve a wide range of industries, including urban logistics and last-mile delivery, unmanned aerial and ground vehicles, industrial mobility and off-grid power applications.
No. STELION hydrogen storage capsules are designed to operate without fixed hydrogen infrastructure. Their plug-and-play design allows deployment in any location, reducing implementation costs and time compared to traditional hydrogen refueling stations.
Yes. STELION Capsules are engineered for safe hydrogen storage and transport, with integrated safety features designed to meet European certification standards. They require no high-pressure hoses or cryogenic systems during operation.
