In 2025, ACAP-supported research at ANU  materially shaped how governments, utilities and developers plan long-duration energy storage. The Pumped Hydro Energy Storage (PHES) Atlases , led by Professor Andrew Blakers  and supported by ACAP, are now embedded in national strategies and commercial pipelines across multiple continents – accelerating the pathway to ultra-low-cost solar (ULCS).   Solving solar’s storage constraint   Ultra-low-cost solar depends on one critical fact

The modelling shows that ultra-low-cost solar fundamentally changes the economics of Australia’s energy transition.

The Australian Silicon Study (AusSi) has identified that a 50,000 tonnes per annum solar-grade polysilicon facility represents the minimum commercially viable scale for production in Australia – aligned with projected global demand of approximately 1.2 terawatts of new solar PV installations annually by 2030. Funded by the Australian Renewable Energy Agency under the Solar SunShot Program, AusSi assesses the technical, commercial and investment feasibility of establishing a l
