The government has published guidance to support operators of anaerobic digestion plants who want to inject biogas into the gas grid.

The document, entitled ‘Biomethane into the Gas Network: A Guide for Producers' has been developed following a Government commitment in the Renewable Energy Strategy in July to explain the gas regulatory system.

DECC claims that it will help producers of biogas, who may not have considered injecting it into the gas grid, to make an informed choice between the various marketing options.

DECC claims that upgrading the biogas to biomethane and sending it to the grid would be more energy efficient, as using the gas on-site for electricity-only applications would harness only 30-35% of the energy in the gas.

This compares to using more than 90% of the energy in the gas in an efficient modern domestic boiler, having transported it through the gas pipe-line system.
