Journal ArticleDOI
Thermal energy storage for direct steam generation
TL;DR: In this article, a three-part storage system is proposed where a phase change material (PCM) storage will be deployed for the two-phase evaporation, while concrete storage is used for storing sensible heat.
Journal ArticleDOI
Test Results of Concrete Thermal Energy Storage for Parabolic Trough Power Plants
TL;DR: In this paper, a 20 m 3 solid media storage test module connected to an electrically heated thermal oil loop was built in Stuttgart, Germany, with a temperature range between 300°C and 400°C.
Journal ArticleDOI
A direct steam generation solar power plant with integrated thermal storage
Jürgen Birnbaum,Markus Eck,Markus Fichtner,Tobias Hirsch,Dorothea Lehmann,Gerhard Zimmermann +5 more
TL;DR: In this article, the interaction between the three subsystems of a parabolic trough power plant with direct steam generation (DSG) is analyzed, and boundary conditions arising from the thermal storage system are identified.
Advanced high temperature latent heat storage system - design and test results
TL;DR: In this paper, a test storage using sodium nitrate as phase change material (PCM) with a melting temperature of 306 °C was operated in a 5 kW laboratory loop.
