Abstract

The need to improve the competitiveness of solar thermal power plants is driving technology development toward higher flux and higher temperatures at the solar receiver. In this context, the search for new thermal fluids that might provide a good thermal performance is opening the door to revisit liquid metals. Sodium has already been used at early experimental projects such as International Energy Agency Small Solar Power Systems in Spain in the 1980s. Extended test campaigns could demonstrate high thermal efficiency of about ...
