Question:
Estimate the specifications for a solar thermal energy plant and storage system. The plant should output a steady 100 MW, 24/7. Assume that the plant is builtin a desert area with an average 250 W/m2 insolation. Assume a gross conversion efficiency of 3%.Tanks of molten salt at 450 ◦C (specific heat capacity 1.5 kJ/kgK) should be able to store 24 hours of power.You can assume that thermal energy from the salt is converted to electrical power with 33% efficiency and that the salt ends up at a temperature of 250 ◦C after transferring its energy to the working fluid that drives the turbine. How big does the plant need to be, and how many kilo tonnes of molten salt are needed per square kilometer of the power plant?
