Argonne National Laboratory (ANL) is working to identify and test new heat-transfer fluids (HTFs) that store energy chemically for more efficient energy transfer in CSP applications. The research team is working to demonstrate the feasibility of using chemically reacting working fluids (CRWFs) as an HTF.

  • Test the efficiency and longevity of candidate systems through repeated cycling in the temperature range of 650°–1200°C
  • Determine each CRWF's potential ability to capture solar heat as chemical energy, in addition to sensible and latent heat
  • Develop predictive models to determine power production and efficiency given various designs and process parameters
  • Validate the models by showing that more than double the power output efficiency of current CSP systems is achievable and scalable.
