Sintesi del contesto e degli obiettivi generali del progetto

The concentrated solar thermal accumulation in CSP makes it one of the most promising renewable alternatives to facilitate the management of the energy mix. The main application of CSP is the production of electricity, but its applications are wider and include, depending on the configuration, since heat input systems for desalination and industrial steam generation to photochemical reactors.
Among the possible actions to reduce the cost of energy production are reductions in CAPEX and OPEX of the solar field and, in turn, improving plant performance. About the 40% of the overall costs of a central tower solar plant corresponds to the solar field, which demonstrates the need to improve the relation between quality-cost from the heliostats. So that, this is the area in which cost reductions will lead to a bigger impact in reducing the cost of energy.
However, for this to become a reality, it is imperative that the solar field is as efficient as possible in both performance and cost, as well as the interrelationships of the pair solar field - receiver are optimized.

Lavoro eseguito dall’inizio del progetto fino alla fine del periodo coperto dalla relazione e principali risultati finora ottenuti

Tewer has proven that the existing solar fields and its performance are not properly optimised and, therefore, this is an important way to reduce the LCOE of tower technology solar plants..

Progressi oltre lo stato dell’arte e potenziale impatto previsto (incluso l’impatto socioeconomico e le implicazioni sociali più ampie del progetto fino ad ora)

Tewer proposes a solution that will mean a spearhead in solar field optimisation, thus optimizing the costs of the solar field, making the technology more competitive. This proposal results in an effective optimisation of solar fields in such a way that the impact in the production and cost of the solar plant is positive and these changes lead to a competitiveness improvement.
