Ecotricity's biogas in National Grid
In order to be injected into the National Grid, biogas needs to comply with quality standards set out by the DOE and Climate Change. But it is thought that these quality requirements could increase the cost of injecting biogas.
At the moment it is more cost-effective to generate electricity by burning the biogas, rather than injecting it into the National Grid, so Ecotricity’s main challenge is to get the right level of gas quality to make it economic.
