Can I thank the Cabinet Secretary for her response? Last week I attended an event run by the Institute of Welsh Affairs regarding the harnessing of renewable energy in the Swansea bay city region. I want to stress again the importance of the tidal lagoon to the region, and ask what support the Welsh Government is giving to improving battery storage, because that really is the answer when we're generating electricity at times when there's not the need for it, and then we haven't got it available when there is the need for it. If we are going to get renewables to work, we need to ensure that both energy generated by the tidal lagoon, and, more specifically, energy generated by solar and by wind turbines, can be stored in such a way that it becomes available perhaps several months later when it's needed. But that needs improved battery technology. So, the question, again, is: what is the Welsh Government doing to support improved battery technology?
