Ms Margie McCarthy:

There is a range of choices there we could talk to. We will not get into energy production. Hydrogen production is an example, where you produce hydrogen by realising our resource and you move it effectively and store energy in that way. Similarly, this would be done - and I mention it a lot - even within the energy hub of a district heating site where you have thermal storage happening in the site. That can meet your heat requirement through the network when you have low, maybe very expensive, electricity and you are using heat pumps to provide your district heating. Instead you start using your thermal storage. This also allows for flexibility on the grid because you are not drawing down electricity at that specific time. If you have amber alerts or something like that, you have thermal storage instead. That is just one example.
