Direct solar steam - phase II

Exploitable results

The DISS (DIrect Solar Steam) Project is a complete R&D program aimed at developing a new generation of Solar Thermal Power Plants with parabolic trough collectors. The final goal of DISS is a 20% increase in performance and 15% reduction in direct investment cost over state-of-the-art parabolic-trough collector solar power plant technology as represented by the SEGS plants currently operating in California. This would lead to a 30% reduction in the cost of electricity generation with this type of solar thermal power plant. DISS-phase I activities are grouped into three tasks: - Design and implementation of a life-size DSG test facility (the so-called DISS Test Facility) at the Plataforma Solar de Almería (PSA): current open questions concerning the DSG processes require a life-size test facility where these processes can be studied under real solar conditions. One of the main project deliverables is the design and implementation of such a test facility at the Plataforma Solar de Almería, a solar research centre in Southern Spain owned by CIEMAT. Though the solar field planned for this facility is to have two parallel rows of collectors, only one complete row has been erected and hooked up to a Balance of Plant (BOP) during the first phase. The second row will be designed and implemented in a future phase; - DSG Applied Research in DSG process thermohydraulics. Results of this task will complement the experiments at the PSA DISS Test Facility; - Collector Improvement: develop and evaluate better parabolic-trough collector components. A small test loop has been erected at the PSA for testing of improved components under real solar conditions.
