Joint Oireachtas Committee on Climate Action

Third Report of the Citizens' Assembly: Discussion (Resumed)

3:00 pm

Mr. John Reilly:

Our twin pronged approach to extending the core of our business is about our power generation business - the electricity business - but also very much about our resource recovery business, as we call it. Bord na Móna has always viewed AD in the first instance as a waste management solution. However, with Origin Green and with the ability of the land to take residual materials getting tighter and tighter, particularly from the agrifood sector, we think AD at scale is certainly likely to have its day. In terms of the economics, the main focus in the last ten or 15 years has been on what renewable energy can be produced from AD. In the scheme of things it is relatively expensive. However, the picture changes if we consider AD in the first instance as a sustainable solution to waste management, particularly at scale. There is a possibility of taking the biogas that is produced there and we are producing electricity from biogas from landfill. We have learned a lot from that. We believe directly injecting that methane back into the gas grid or potentially using it as compressed natural gas - a renewable gas as it is defined - will help the decarbonisation of the heating and transport sectors. The project we are developing in Laois is focused first and foremost on doing it at scale, using that landbank to collect the waste, and then examining the direct injection into the gas grid of the methane or biomethane produced. We have had great co-operation with Gas Networks Ireland. This is something we could not have done four or five years ago. It is the real manifestation of decarbonisation with organisations and companies working together. The technical end of it is doable. With all these things it comes down to the commercials but we are going to work very hard at trying to deliver projects at scale that can make a contribution. We believe that over time, in an increasingly carbon constrained world, these types of technologies will become increasingly commercial.
