Ann: 50MW Solar Project Revenue Update, page-11

I looked at it, but there are no economics - its just a punt. I think GNX would not look at using that tech - you need to use heat for something to make it work

IF it made sense - you would not store electricity as heat - you would use solar thermal for heat. the fact that they aren't means they are relying on surplus electricity (eg when the sun is shining and wind blowing at the same time and prices fall)

I guess the people who invest arent looking at the economics
