Larger plants are more competitive
Larger plants are more competitive
It turns out that (very) large AD plants are more competitive (CapEx decrease per Nm3 of biomethane) and needs less tie-in points for grid injection which is a good point for biomethane development. Recently, CIP and its partners disclosed the biomethane platform Greengate Biogas for the construction of 7 plants of 250 GWh/y of biomethane capacity in Ireland. Do you think this will be the standard from now on?

Reply by Dr. Nick Primmer @future-biogas : Yes, economies of scale can help unlock the potential of AD – we at Future Biogas are targeting 100-150 GWh plants. Nevertheless, small plants may find a niche in remote/off-grid communities.
Comment by Sara Bartle @rea : Again, I agree it’s a matter for economies of scale and this may be a reason why smaller plants have been less incentivised to participate with the more recent support schemes. Although most will state that the additional costs for connecting to a grid and significantly upgrading from biogas to biomethane are barriers. There is a good argument for encouraging smaller plants where they can manage a more local feedstock and digestate management. They can also produce biogas or transport fuels rather than having to commit to grid connections and/or biomethane upgrading costs. However, these plants may struggle with the initial investment costs unless otherwise supported.
