Joint Oireachtas Committee on Social Protection

National Action Plan on the Development of the Islands: Discussion (Resumed)

Mr. Philip Newsome:

Just to add to Mr. Finnegan’s response, there is a real question on the trade-off between more electricity links back to the mainland and some other alternative uses, such as green hydrogen production. In a way, at a micro level, that reflects a larger question in terms of, say, how we might use our offshore wind resources, particularly in the Atlantic. Is it better that they are coupled with electricity interconnection that we can then export back to Europe or does it make sense to co-locate them with electrolysers and produce hydrogen? In a slightly different way, a question for some of the islands is what are the cost trade-offs between those two? That is something that may well change quite radically as technologies mature. Hopefully the cost of producing solar and wind will come down and make the green hydrogen more economical. That may mean that you kind of look at the options around the cable or producing hydrogen. Those are some of the questions to be explored.
