Polygeneration Systems


The heat produced by solar concentrating collectors could be also used not only for one process but also in combination. Thus, combining power generation, cooling and heating system in polygeneration systems can increase the net energy output of the collectors. The following list shows some possible combinations of solar polygeneration processes:


  • power generation (CSP), hot water


  • power generation (CSP), refrigeration


  • power generation (CSP), cooling, domestic hot water


  • power generation (CSP), seawater/water desalination, domestic hot water
  • seawater/water desalination, hot water


Polygeneration for power production (CSP) is particularly interesting when unstable power grids or off-grid applications are considered. Diesel generators are then used traditionally with high electricity costs.
