Launch of the POLYPHEM project!


The H2020 POLYPHEM project was launched on the 1st of April 2018 for a duration of 4 years until the 31st of March 2022.

The main objective of POLYPHEM is to improve the flexibility and the performance of small-scale Concentrated Solar Power plants. The outcomes of the project will allow in the short term to reinforce the competitiveness of this new low carbon energy technology and therefore to favour its integration in the European energy mix.

The technology consists of a solar-driven micro gas-turbine as top cycle and an Organic Rankine Cycle as bottom cycle. There is no water requirement for cooling. A thermal energy storage is integrated between both cycles. The resulting power block is a solar power generation system able to meet the requirements of a local variable demand of energy with a high average conversion efficiency of 18% and a low environmental profile with an investment cost target below 5 €/W. Besides electricity generation, other applications will be considered for future developments, such as heating/cooling of multi-family buildings or water desalination for small communities.
