    This pioneering project will see gas distribution networks (GDNs) Cadent, SGN, Wales & West Utilities and Gas Networks Ireland work with innovators Bohr, Renda and Thyson Technology (part of the nZero Group) to develop new sensors that accurately measure the energy content of gas across the network.

    The technology could significantly enable radical accelerated growth of green gases such as biomethane and hydrogen.

    New Gas Calorific Sensor to be developed

    Gas customers are currently billed on energy density measurements taken far upstream, which can pose challenges to green gas producers connecting to distribution networks.

    The three new types of sensors being developed will allow for measurements of calorific value across the distribution network without the need to vent gas. This project aims to find a solution to this challenge that is accurate, fair and affordable, and provide GDNs with increased visibility of their network operations.

    Each of the innovators will develop and test a number of prototype sensors over the next 12 months, with an aim to progress to a small-scale pilot trial in 2026.

    The project will be facilitated by the Energy Innovation Centre (EIC), based in Ellesmere Port, Cheshire and delivered using the Network Innovation Allowance (NIA) and Gas Networks Ireland’s Network Based Innovation Fund.

    Jane Blackwell, Head of Operations at the EIC said: "This is a hugely exciting project to launch and one we’re delighted to be managing. The benefits could be extensive, from fairer bills to customers to supporting net zero targets.

    We look forward to working with the gas networks and technical partners to deliver this fascinating project.

    Adam Hassall, Innovation Specialist from Cadent said, We are excited to play a lead role in this initiative, which places collaboration at its heart and could become the cornerstone for how greener alternative gasses are utilised across the UK energy market in the future.

    Cadent

    Cadent is the UK’s largest gas distribution network with a 200-year legacy. We are in a unique position to build on strong foundations whilst encouraging the curiosity to think differently and the courage to embrace change. Day to day we continue to operate, maintain and innovate the UK’s largest gas network, transporting gas safely and protecting people in an emergency. Our skilled engineers and specialists remain committed to the communities we serve, working day and night to ensure gas reaches 11 million homes from Cumbria to North London and the Welsh Borders to East Anglia, to keep your energy flowing.

    Future of Gas:

    Here at Cadent we support the Government’s plans to reach Net Zero by 2050. That means we’re backing the introduction of hydrogen as a low carbon alternative to natural gas for the future. We know people love the controllability of gas and, with our network already in place, it makes sense to switch to the lower carbon alternative offered by hydrogen, which we believe can keep homes and businesses warm for generations to come.
