Netherlands-based natural gas infrastructure and transportation company Gasunie announced that its subsidiaries Gasunie New Energy and Gasunie EnergyStock are developing a 1 MW power-to-gas pilot project at the company’s underground gas storage facility at Zuidwending near Veendam, in the province of Groningen in the northeast of the Netherlands.
The HyStock installation will be powered by 5,000 solar modules installed on earth embankments surrounding the facility and on the roofs of its parking area. Power generated by the PV array will be converted into hydrogen. The technology is considered a feasible solution for the storage of temporary surpluses of wind and solar power.
Gasuine claims that its underground gas storage facility at Zuidwending is particularly suitable for future large-scale storage of hydrogen in salt caverns made especially for gas storage.
The two companies will decide if the project will be further developed this summer. Gasunie said it sees the conversion of power-to-gas as a promising technology in which gas infrastructure can play a connecting role.
Both units were created by Gasunie in 2014. Gasunie New Energy is currently implementing a large-scale, fully integrated power-to-gas plant in Delfzijl in the north of The Netherlands together with Torrgas, Siemens, Stedin, Gasunie, A.Hak, the Hanze University of Applied Sciences/EnTranCe and the Energy Valley. The 12 MW installation is expected to produce hydrogen and syngas for the chemical industry.
