Altech Batteries has secured the necessary environmental and construction permit to build the company's Cerenergy GridPack production facility in Saxony, Germany, and can now focus on locking in project finance for the build. The Subiaco-based company began the permit application process in September 2023 for its 120-megawatt Cerenergy facility, which will produce a battery based on common table salt. The company's definitive feasibility study (DFS) for the project indicates a pre-tax net present value of €169 million (A$291m), annual revenue of €106m (A$182m), a €51m (A$88m) EBITDA and a 3.7-year payback period. With the approval now in Altech's kit bag, the company can now move to secure the necessary finance to build the project, which was recently awarded "Dark Green" certification – the highest rating offered by global ratings agency Standard & Poor's – for the Cerenergy salt battery project.
