Hydrogen Fuel Cell Operating Hub for Repex/Large-Scale Projects
Abstract
To maintain their above ground and underground pipework assets, all Gas Distribution Networks (GDN) operate substantial fleets of commercial vehicles (primarily vans, but also HGVs), together with mobile plant and powered equipment. Presently, there is a complete reliance on hydrocarbon fuels, primarily diesel and petrol. Both fuel types are usually sourced via the public retail forecourt network. Similar issues exist for other utility providers that operate underground and overground infrastructure.
Wales & West Utilities is undertaking a major programme of change to support decarbonisation and deliver a hydrogen-ready, Net Zero gas network. Our distribution network iron mains replacement programme (Repex) requires significant excavation and pipe replacement activity, laying long-life, hydrogen-ready polyethylene pipe by a variety of means.
The project endeavours to identify a suite of suitable zero-emission mobile plant assets, tools and equipment for carrying out Repex work that WWU could hire or purchase for operational trials, and to identify opportunities for changing equipment items to simplify recharging/refuelling requirements in the future.
The objectives of this project are:
- To analyse current energy demands, sound pressure and vibration levels associated with existing ICE powered mobile plant assets, ICE-powered tools and equipment and electrical equipment used for carrying out planned iron mains replacement work on the gas distribution network.
- To estimate the future electrical energy demands (and sound pressure and vibration levels) placed by future zero-emission powered tools and equipment on a zero-emission site-based power generation facility.
- To identify opportunities for changing equipment items to simplify recharging/refuelling requirements in future.
- To identify a suite of suitable zero-emission mobile plant assets, tools and equipment that WWU could hire (or purchase) and utilise for operational trials, short and longer term. This will include the energy source and the means of recharging and/or refuelling on site and/or at regional depot locations.
