Joint Oireachtas Committee on Climate Action
Decarbonisation of the Heat Sector: Discussion (Resumed)
Dr. David Connolly:
For some, it might require new plant but many can actually use the waste heat streams. We have a projection for today and we have a projection for 2030. Let us ignore today and just talk about 2030 because, by the time district heating is at scale, that is likely where we will be. Even in the year 2030, we will have more waste heat in Ireland than is needed to heat all buildings, based on our forecast. What will happen is that, depending on where we start a network, we will either get that on day one or, as the network grows, we will reach it eventually. Let us talk about Cork versus Dublin, no better analogy. Dublin can access its waste heat very quickly because it is located right in the city centre.
In Cork, a large amount of waste heat is quite a distance from the city, in Aghada and the refinery area. They will not get access to that for many years.
