HPS2 focuses on the demonstration of the safe and efficient operation of a parabolic trough plant with molten salt as heat transfer and storage medium, including operation of a steam generator. It is the first project on EMSP. Within HPS2, the basic infrastructure will be established allowing to extend the plant with future R&D projects on a demonstration scale for molten salt.
Specifications:
- Expected thermal power of the solar field up to 3.5 MWth (total length 684 m, HelioTrough® 2.0);
- Plant design temperature up to 565 °C;
- Once-through steam generating system (1,6 MWth, 140 bar steam pressure);
- 2-tank thermal energy storage (3 hours capacity @ ΔT = 280 K);
- Commissioning ongoing;
- 1 st operation phase with ternary salt mixture up to 500 °C.
