Unique Fresnel Demonstrator Including ORC and Thermocline Direct Thermal Storage: Operating Experience

A unique Fresnel prototype is currently running in France. It is composed of a 1000 m2 solar field, a thermocline thermal storage and an Organic Rankine Cycle (ORC). This CSP plant is perfectly suited to test the three main parts of a solar power plant (ie. solar field, storage and turbine). More th...

Description
Summary:A unique Fresnel prototype is currently running in France. It is composed of a 1000 m2 solar field, a thermocline thermal storage and an Organic Rankine Cycle (ORC). This CSP plant is perfectly suited to test the three main parts of a solar power plant (ie. solar field, storage and turbine). More than two years of experience is achieved and the paper aims at presenting some results about this operating period. It shows that this kind of technology is very versatile. Automation experiences along with thermocline behavior are discussed. Electricity production using the storage capacity is also presented. This experimental tool will be upgraded with water chilled production and desalination. The perspective is the optimization of the whole system for MW scale installations.
