Concentrating solar energy systems can serve many applications beyond electric power generation. GlassPoint Solar has introduced an Enclosed Trough Once-Through Steam Generator system that is adaptable to challenging environments and meets all requirements for Solar Thermal Enhanced Oil Recovery (EOR). In this system, troughs are enclosed in a modified agricultural glasshouse. This innovation, when combined with an air filtration system and automatic roof washers, dramatically reduces energy losses due to soiling and wind. In addition, the Once-Through design allows the use of feed-water with total dissolved solids as high as 30,000 ppm to produce 80% quality steam at 100 bar, matching typical EOR specifications. Performance during the first four months of production operation is reviewed. A dust storm during the period confirms the efficacy of the glasshouse and roofwasher in minimizing operational impacts of weather phenomena common in the MENA region. Output is determined to be consistent with the company’s energy yield model. Plant reliability is monitored and 99.8% uptime is measured in the fourth month of operation.
