Biomethane Gas Injections

Our Aim is to facilitate new connections to our gas distribution network that will enable biomethane producers to inject their renewable gas into the pipeline and grid network. The addition of biomethane into the grid will help the UK minimise its carbon footprint and avert from unsustainable fossil fuels, whilst increasing the security and diversity of energy supplies.
