In July 2016, the H21 Leeds City Gate report was launched in Westminster. Using England’s fourth largest city as a blueprint, this pioneering feasibility study, led by Northern Gas Networks, confirmed that conversion of the UK gas network to 100% hydrogen was both technically possible and could be delivered at a realistic cost.
It provided evidence that the UK gas networks are the correct capacity to be converted to 100% hydrogen, low carbon hydrogen could be credibly sourced at scale, conversion of UK cities could be achieved incrementally, appliances could be converted to operate on 100% hydrogen, and hydrogen could be stored to manage intraday and inter-seasonal swings in demand.
