Project Profile: Reducing the Cost of Thermal Energy Storage for Parabolic Trough Solar Power Plants

Abengoa logoAbengoa, under the Thermal Storage FOA, is looking at innovative ways to reduce thermal energy storage (TES) system costs.

  • Identify opportunities for cost reduction in near-term TES systems
  • Identify two mid-term TES options with greater opportunities for cost reduction
  • Demonstrate the TES options with the best cost reduction potential for parabolic troughs plants in the near and mid-term


Abengoa is evaluating several topologies for parabolic trough plants with storage and performing cost comparisons to determine relative advantages. Two topologies are being selected for development into system demonstrations.
