Refuelling the UK Cadent and CNG Fuels won the Environment Award at last year's Utility Week Awards. In the first of a series of case studies featuring awards winners, we asked them how. Winner's comments "The Utility Week Award has helped to highlight how CNG filling stations connected to the local transmission system, are a practi- cal and affordable option to decarbonise HGV transport, reduce greenhouse gas emissions and contribute to clean air. It supports our work with the transport sector and government, encouraging investment and removing barriers to growth." RICHARD COOK, LEAD PROJECT MANAGER, CADENT Introduction In partnership with CNG Fuels, Cadent invested in the creation of the UK's first com- mercial high-pressure compressed natural gas (CNG) refuelling station for HGVs. The facility is connected to the company's high- pressure local transmission system at Ley- land, Lancashire, and has been operating since February 2016. Cadent said it believes its network has great potential as a nationwide infrastruc- ture to support a low-carbon energy future for transport. The goal of this initial project was to demonstrate the efficiencies and ben- efits – including greenhouse gas and emis- sions benefits – of using the high-pressure local transmission system to connect CNG filling stations, over and above connections to the medium-pressure system. Why this approach? Although the UK already had CNG stations drawing on the medium and intermediate pressure pipelines, the proposal for Leyland was the first station to realise the further benefits from connecting directly to the high- pressure pipeline – the local transmission system (LTS). Connecting directly means less energy is needed to compress the gas for use as fuel. In addition, there is no leakage from the LTS system, meaning that the "well-to-wheel" emission figures for vehicles becomes highly favourable. By providing detailed design, installa- tion and commissioning information about an LTS connection, Leyland can act as a catalyst to allow the UK gas network to be utilised for more lower carbon transport into the future. Company impact This innovation project fitted specifically into Cadent's work exploring the future role of gas. The company says it is leading several "ambitious projects" to understand how gas can help the UK meet its climate reduction targets for heat and transport, in a way that is both practical and affordable for customers. The results from Leyland have provided important evidence about the environmen- tal benefits of stations connected to the LTS. This supports Cadent's view that CNG could and should be the fuel of choice for HGVs and buses and the company is currently looking into other stations on its network. l A full-length case study on this Award winner is available at: www.utilityweek.co.uk Cadent and CNG Fuels accepting their award
