Dr. Muireann Lynch:

Yes. The other alternatives are something like CCS and, again, immature technology we have no experience with. I would not rule it out. We did some research that showed it was relatively competitive. Once you get to the high levels of renewables we are targeting, the marginal cost gets really high. The current target is 80% by 2030. Realistically, that is going to be so expensive that other expensive technologies like CCS will start to play ball.
