Combined Heat and Cooling Power
When smaller plant sizes with possibly lower operating temperatures are close to economical regenerative electricity production, a combination with the use of heat for process heat or cooling purposes may lead to better economics. Using the same solar field for different purposes depending on the time of day or time of year is interesting, if temperatures and load profiles fit together. For example a solar field producing more heat in the summer can be used to drive solar absorption cooling in summer. During the year a rather constant solar share can be used for solar electricity production. This avoids oversizing and dumping of excess solar heat in the summer. The potential for solar process heat with temperatures between 80°C an 250°C is huge throughout Europe.
