In Poland, railway electrification has reached 98%, with only one remaining unelectrified route. The trains run directly on electric power supplied via overhead lines. The station where the container is located is a substation equipped with a battery backup, which is used to buffer power outages in the railway network.

To create a grid-balancing and train-recharging application a lot of components had to work together – production, storage, compression, and re-use of hydrogen for electrical power was all part of the process.

On this project, we worked closely with our partners MSR ( and DSHP (
