Mr. Brendan Tuohy:

I would change the timeline slightly, if I could. By 2050, we are talking about decarbonising the networks. Then what one is talking about doing, as one puts on gas or one moves towards an unfossilled gas, in the sense that it could be other generation type; one could even have hydrogen or one could have a mixture of things such as carbon capture sequestration where even though one is producing fossil fuels one is treating them again.

The aspiration must be to have a decarbonised network by 2050. That is what Britain and others have announced. To get to the first stage of that, our challenges will be in the mid-2020s, as we see some of the traditional coal and other plants coming off stream and making sure that the new systems are in place to deal with that. That is challenging.
