Summary
RWE and SGN have signed a memorandum of understanding (MoU) to investigate the development of wind-supplied electrolysis in Scotland to supply heating demand.
Electricity from RWE’s Scottish onshore wind portfolio, which has a combined capacity of 213MW, will be used to produce hydrogen to supply homes and businesses via Scotland’s gas network.
The partnership will investigate the decarbonisation of homes and businesses connected to the networks of Campbeltown, Stornoway, Oban, Thurso and Wick, which are not connected to the mains gas network.
These networks are currently supplied by liquified natural gas (LNG) and liquified petroleum gas (LPG), which when swapped with hydrogen could save 21,000 tonnes of carbon each year and decarbonise around 9500 properties.
The partnership will define how much hydrogen is needed, the requirements to convert these networks to hydrogen, and the supply of green electrolytic hydrogen from RWE’s onshore wind farms nearby.
In doing so, the project could also unlock onshore wind farm developments in grid-constrained areas, by providing a use for the green electricity generated.
A feasibility study will also be conducted over the coming months into a 100MW electrolyser at RWE’s Markinch combined heat and power biomass plant.
