An Investigation for Direct Steam Generation Parabolic Trough vs. Linear Fresnel System Applied in Egyptian Hotels

Renewable energy is becoming widespread today in various fields, as solar technologies contribute to provide an alternative to fossil fuels. The two technologies discussed in this paper are Parabolic trough and Linear Fresnel Direct Steam Generation. This work is presented on Egypt discussing its energy situation and demands, showing that one of the most consuming energy sectors are hotels and resorts. As Egypt is considered being a tourism attraction including various types of tourism, that means there are huge numbers of hotels and resorts all over the country in various regions that are not enough developed providing all services and depending mainly on fossil fuels. The study was deployed on Aswan in Egypt using the two different technologies. The effect of reflective mirror area is being analyzed, to show which system is more efficient and suitable and how it can be applied for the hotels. The main part of the simulation was done showing how Direct Steam Generation technology can be applied and the amount of steam it can produce during the four seasons of the year. The results show that PTC Direct steam generation is more suitable, as it has a better ability for steam production and water heating, which is the bigger sector of the hotels consumption and needs.
