Off-grid power for railway networks

Intelligent Energy is supporting partner H2 Core Systems and their customer, SBB Energy, with back up power on railway networks in Poland.

In Poland, railway electrification has reached 98%, with only one remaining unelectrified route. The trains run directly on electric power supplied via overhead lines.

At Garbce Traction Substation in south-west Poland, PKP Energetyka, an electricity distributor to the Polish railway network, and SBB Energy have installed a system to test the feasibility of using green hydrogen for powering railroads in the future.

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.

When there’s a surplus of solar power, the local 150 kWp PV array supplies 15 AEM Electrolysers to produce onsite green hydrogen for long-term energy storage. Thanks to its modularity, Enapter’s flexible 36kW green hydrogen system can ramp up and down quickly to harvest as much sunshine as possible.

The idea is to complement an existing short-term battery system with a storage system able to hold up to 23kg of hydrogen at 99.999% purity that can be reconverted to electricity via five Intelligent Energy 4kW fuel cells to buffer power outages in the railway network.
