We are investing in the manufacture and distribution of low-cost, long-life, baseload iron flow batteries that allow grid-scale energy storage for wholesale electricity generators, energy retailers and commercial and industrial customers. Energy Storage Industries - Asia Pacific (ESI) is a Queensland-based, 100 per cent Australian-owned company that provides reliable and environmentally friendly r
enewable energy storage solutions that are essential for Australia’s transition to a renewable energy future. We are investing up to $70 million in Maryborough to manufacture and distribute low-cost, long-life iron flow batteries that allow large-scale energy storage for wholesale electricity generators, energy retailers, and commercial and industrial (C&I) customers. We are also investing in the manufacture of small, modular distributed energy storage units that can be installed in low voltage networks and microgrids, and behind the meter installations for C&I customers. Our iron flow batteries are completely sustainable and 100 per cent recyclable, and the environmentally friendly electrolyte means that the product is ideally suited to remote locations such as the National Parks and the Great Barrier Reef. ESI is fully integrated — we manufacture, install, maintain and finance energy storage solutions. Importantly, the technology is backed by leading global re-insurance company Munich Re, which mitigates risk for ESI’s customers. Partnering with Munich RE, we have launched an industry-first insurance coverage for our battery flow technology. This world-first innovative policy means that our long-duration storage solutions are now baked by a full 10-year performance guarantee, regardless of project size or where it's located. ESI provides a significant social and economic boost to the Australian community. Initially, we are investing up to $70 million to build a manufacturing hub in Maryborough. When fully operational in 2026, ESI will have up to 500 highly skilled employees and contractors working at our facilities throughout regional Queensland. ESI is run by a board and executive team that has decades of experience in the energy, manufacturing, technology and finance sectors. Importantly, they have a deep, end-to-end understanding of the energy value chain from technical operation of assets to energy trading.
