Stream 2 aims to accelerate commercialisation of innovative longer duration energy storage projects through to first-of-a-kind (FOAK) full-system prototypes. Phase 1 projects will be expected to deliver a feasibility study report for their proposed technology and contribute to knowledge dissemination and sector capacity-building.
The following 19 projects have received funding for Stream 2, Phase 1.
