Western Australia’s (WA) GreenTech Hub has hit another major milestone, announcing 12 successful finalists for its inaugural Long Game Energy Storage Innovation Challenge.
The Challenge invited innovators from around the world to submit innovative and commercially feasible long-duration energy storage solutions to meet WA’s unique energy needs.
More than 30 local and international innovators submitted proposed solutions to the Challenge, with one in three hailing from WA.
The 12 finalists of the Long Game Energy Storage Innovation Challenge are:
- Allegro Energy - Australian innovators in Microemulsion Flow Battery (MeFB) combining Australian-made innovation with a patented microemulsion electrolyte to deliver long duration energy storage.
- BroadBit Batteries - Finish innovators with a new sodium-based LDES solution that can achieve greater material efficiencies, cost reduction and lower emissions than current alternatives.
- Energy Dome – Italian innovators whose CO2 Battery provides long duration of dispatchable storage in compressing CO2 and simultaneously captures heat from that compression.
- e-Zinc - e-Zinc are Canadian innovators with a breakthrough LDES technology using a proprietary zinc-air energy storage system.
- Hynertech Australia - Australian innovators with a new Liquid Organic Hydrogen Carriers (LOHC) catalyst combination designed to store and release hydrogen in a reversible chemical reaction.
- Isothermix - Australian innovators whose ChillBank™ uses intelligent systems and highly optimised phase change proprietary materials to store renewable energy as heat.
- Knode - WA-based innovators whose proprietary MGA thermal blocks can be flexibly charged through electrically powered resistance heaters or by capturing waste heat from existing processes.
- Noon Energy - US innovators developing industrial scale LDES solution comprised of a power block, which uses reversible solid oxide electrolyser/fuel cell technology and high density water and industrial gases as storage media.
- RayGen Resources - Australian innovators whose system uses mirrors to concentrate sunlight onto proprietary Australian-made, highly efficient solar modules, which captures heat and stores it in water reservoirs.
- RENOZ Energy - WA-based RENOZ Energy is developing a chemistry-agnostic LDES platform using Brill Power's Oxford-developed Battery Intelligence System. Their solution adapts to current and future chemistries.
- Sumitomo SHI FW - based in Finland, they are developers of grid scale Liquid Air Energy Storage with 25 to 100MW, long duration energy storage capacity.
- The Green Energy Company - The Green Energy Company is establishing WA’s first local assembly and integration of non-flammable, long-life Hybrid Graphene batteries that deliver long-duration energy storage.
Finalists have been invited to take part in the Long Game Live, an invite-only satellite event of West Tech Fest 2025, to pitch their long-duration energy storage solutions against WA defined use cases.
Running from December 8-12 in sunny Perth, West Tech Fest is Australia’s longest-running tech and innovation festival.
The GreenTech Hub is one of WA’s five innovation hubs, funded through our Department’s New Industries and Innovation Fund.
Operated by Curtin University, the Hub connects industry, innovators, research and government to develop practical, scalable solutions in green technologies and services that are tailored to WA’s unique industry, infrastructure and community needs.
