Concentrated solar power (CSP) traditionally uses large arrays of mirrors to direct sunlight onto a tall central receiver tower, which then creates heat that is stored in various liquids for use when the sun is not shining to generate electricity. CSP offers storage that traditional solar (PV) systems do not, however they have been historically big and expensive. An Australian company has developed a smaller, cheaper CSP and PV combination, with a 70% efficiency rate (on par with pumped hydro). The pilot project is currently operating in Carwarp, Victoria, Australia. https://reneweconomy.com.au/the-australian-solar-tech-that-may-have-found-a-low-cost-solution-to-deep-storage/
