Dr. Karl Richards:

I will add to that. The SEAI contracted a study to examine the carbon intensity of AD biogas generation because it has to meet the renewable energy directive requirements. You have to displace a huge amount of carbon relative to standard fossil-fuel gas. The calculations were made, and the grass is to boost the methane yields coming from AD. However, there are some plants being proposed that will be 100% slurry based and not have any grass going into them.
