• Greening the gas


      Our long term strategy is to increase
    the volume of 'green gas' entering
    our network.


    This is a clean and renewable source
    of energy which can help the
    country meet its climate
    change targets.
      We're aiming
    to have 250,000
    customers supplied
    with  green gas by
    material such as
    food waste is
    broken down
    by bacteria.
          The bacteria produce
    biogas rich in methane.
    We remove any
    contaminants from
    the gas and inject it
    into our network.
    process is called
    anaerobic digestion
    and also occurs
    in a cow's stomach.



    We are leading the way in the development of green gas and were the first gas distribution company to inject biomethane into the network at Didcot in Oxfordshire. SGN is a leading partner in the UK’s first and longest running commercial biomethane project at Poundbury in Dorset, and also Scotland’s first biomethane production facilities in Coupar Angus, Perth and Girvan, South Ayrshire.

    Greening the gas that passes through our network is at the heart of our vision for an enduring and sustainable gas network. Our ambition is to continue to be the leading network for green gas connections and have 250,000 homes and businesses supplied with green gas by 2021. We believe this innovative use of our gas network is a vital component of a sustainable energy future.

    The gas industry faces the challenge of ensuring sustainable and secure sources of gas can be provided for generations to come. The UK has a legally binding target to promote sources of renewable energy and reduce carbon emissions by at least 80% from 1990 levels by 2050.

    Green gas is a clean and renewable source of energy which can help our country meet its climate change targets. It can be produced from many different sources including sewage, food waste and energy crops. This organic material is broken-down by ‘anaerobic digestion’.

    ‘Anaerobic digestion’ is a natural process where, in the absence of oxygen, organic material is broken-down by micro-organisms, just like grass is broken-down in a cow’s stomach. This process produces biogas, which is rich in methane. Once the biogas has been cleaned up to remove unwanted contaminants, the resulting biomethane can be injected directly into the gas network where it works like natural gas providing energy for heating and cooking.

    Biogas documents

    We are one of the country’s leading authorities in biogas development, acting as both the regulated gas network (transporting the gas) and also through our commercial business where we can provide the services and manage the process of treating biogas and injecting it into the network.

    The future of gas networks

    This document sets out our thoughts on the role of distributed gas as we move into future price regulation periods and how the gas distribution networks can underpin a secure and affordable future lower carbon energy mix.
