Direct steam generation for process heat using Fresnel collectors

Abstract

Industrial energy consumption represents one third of the total energy used worldwide, significant amount of which is thermal energy. This paper discusses the use of Fresnel collectors to provide saturated steam for process heat usage through Direct Steam Generation (DSG) which is a promising technology for introducing solar energy for industrial use. In this work the challenges imposed by the non-linear dynamics of DSG technology in solar system are discussed in addition to the strategies used to overcome these challenges. Moreover, advanced concepts for integrating solar DSG systems in industrial settings are presented in the framework of the SolSteam Project. In addition we present details from the current commercial DSG project being constructed Jordan which represents the first solar DSG plant in MENA.
