Question 2

What demand of energy takes the biggest part of the energy consumption?

Answer 2

The demand for heating and cooling applications (48.8% of all energy)

Question 3

What are forms of seasonal storage that can be used at CSP plants?

Answer 3

1. Pit storage (water up to 95*)
2. Tank storage (400-550* depending on used HTF)

Question 4

What is pit storage?

Answer 4

Pit thermal energy storage systems are artificial pools in which a large pit is sealed off from the soil, insulated, filled with water, and given a floating cover. The water can be heated by various heat sources, for example solar collectors or waste heat.

Question 5

Why should seasonal storage be used at CSP plants?

Answer 5

To deal with the variability of solar power on daily and seasonal basis to provide a continuous power output.
