Melbourne battery innovation moves towards local manufacturing with ARENA support

Clutch Industries is establishing a manufacturing line for solid-state batteries in Coburg North, Victoria, with $6.77 million in ARENA funding. The $19.35 million project will produce the PowerNet battery, a 4 kWh modular unit designed for household storage or portable use in caravans and boats. The line will include semi-automated assembly, testing and quality assurance. The company aims to move the technology from development into commercial-scale production and gather real-world performance data across different applications.

Where this fits

This is a sovereignty and supply-chain story. Australia's battery manufacturing has been almost entirely offshored to China, which now controls 80 per cent of global battery cell production and dominates processing of lithium, nickel and cobalt. A local production line for energy storage, even at modest scale, begins to address that dependence. The solid-state architecture is a genuine technical advance, higher energy density, lighter weight, safer chemistry, but it does not change the underlying arithmetic: a renewables-heavy grid requires battery storage at scale, and Australia is building that storage on a supply chain it does not control.

What it means

Domestic battery manufacturing is necessary but not sufficient for energy security. The cells, materials and critical inputs will still depend on global supply chains dominated by China unless processing capacity follows. More fundamentally, the grid problem remains: batteries store energy but do not generate it reliably. A home or vehicle battery solves the micro problem. The macro problem, firming a national grid through weather-dependent cycles, still requires either vast overbuild of renewables plus transmission, or firm dispatchable generation. That Australia is pursuing the first path while legal prohibition blocks the second is a choice about cost and sovereignty, not technology.
