Connecting to the Gas Grid

As part of our support to potential biomethane projects, we have access to all gas Grid Network Maps owned by Cadent, Wales & West Utilities, Northern Gas Networks, and Scotia Gas Networks (including Southern Gas Networks). With access to these Gas Grid Maps, we are now offering a free service to assist clients with determining if there are suitable gas pipelines in the area. We will provide Satellite and gas grid view maps showing the closest connections and pressure of gas mains in the area of interest. Once connection points have been identified, we can also progress the query directly with the Grid owners for confirmation of pipeline capacity to ensure your project has the opportunity to go down the biomethane to grid route.

CNG Services can offer a full connection design and construction service at any network pressure. For further details see the Pipelines section.

Once you’re connected, the biomethane needs to be shipped by a licensed gas shipper. Barrow Shipping Ltd is the UK’s only 100% biomethane shipper and is focused on meeting the specific needs of the biomethane sector – for more information visit the Barrow Shipping website.


Natural Gas contains around 90% methane, the remaining 10% is a mixture of ethane, butane, propane, carbon dioxide, nitrogen, and many other trace constituents. Biogas from an anaerobic digester typically contains 65% methane and 35% carbon dioxide but with suitable processing, the carbon dioxide can be removed resulting in a gas stream that contains up to 96% methane… Biomethane. A clean, simple, and renewable energy source.
