Advantages of CSP for Australia

  • Low cost integrated storage
  • Fully dispatchable
  • Synchronous power generation --> Grid stability
  • High local content (vs PV)
  • Potential for using high-temperature process

heat directly

  • Applicability of CHP

Challenges to CSP

  • Perceived complexity
  • Perceived high cost
  • Low Technology Readiness Level (TRL) of high-

temperature solution

  • Larger plant size to achieve low LCOE
  • Low amount of install base (reference plants)

ASTRI Role for CSP in Australia

  • Increase TRL for component technologies for Hi-T CSP
  • Build Integration Test Facility to demonstrate

component performance and operability in integrated system

  • Continue to build CSP capability in Australia
  • Connect with international CSP community
  • Engage industry partners to accelerate

commercialization of CSP in Australia

  • Advise ARENA on future project funding in CSP
  • Advise industry on CSP commercialization path
