Hydrogen fuel cell system to power Viking Link site

News

A hydrogen fuel cell system has been delivered by Siemens Energy and GeoPura to provide off grid power and heat to National Grid’s UK Viking Link construction site in Lincolnshire.

According to Siemens, the fuel cell arrangement will serve the site during a period of six to eight months when the remote site is without a grid connection.

The system will provide 250kVA of standard three phase, 400V electrical power and up to 80kW of heating to around 20 cabins across the construction village.

Demonstrated by Siemens at the Goodwood Festival of Speed in 2019, the fuel cell system has been further developed by GeoPura to use waste heat that is passed through a heat exchanger to heat water. The water is then piped to heat two drying rooms for the site workers’ personal protective equipment.

According to Siemens, the fuel cell system is incorporates 216kWh of battery storage, used to smooth the peaks in power demand and improve the efficiency of the system.  The battery storage also means that should the hydrogen supply be interrupted, the output of the system will be unaffected and can supply power autonomously for several hours.
