Report: RayGen Solar Power Plant One Lessons Learnt (PDF 181KB)
This report covers lessons from the project such as cold storage, grid connection and financing.
RayGen’s cold storage stores thermal energy in the sensible heat of water (between two temperatures), rather than the latent heat of freezing ice. RayGen’s investigations showed cold thermal storage without ice was a lower risk, lower complexity and already proven solution. RayGen’s cold storage reservoir may be the largest cold storage unit ever deployed globally and relies on principles from pit thermal energy storage (PTES) of solar heat in district energy systems. Ice-based cold storage has never been deployed at this order of magnitude and presents risk.
