Altech batteries (ASX:ATC) has signed a second letter of intent for its CERENERGY GridPack battery energy storage system, marking a significant step in its commercialization efforts. The agreement is with Referenzkraftwerk Lausitz GmbH (RefLau), a joint venture between German renewable energy companies Enertrag SE and Energiequelle GmbH.
This follows Altech’s initial retirement agreement, announced in September, with Zweckverband Industriepark Schwarze Pumpe, which oversees the Schwarze Pumpe industrial park.
Under the terms of the agreement, RefLau will purchase 30 MWh of CERENERGY energy storage in the first year of production, rising to 32 MWh per year for the next four years. Deliveries are expected to begin at the end of 2026, following the commissioning of Altech’s production plant and RefLau’s reference power plant in Lausitz, Germany.
CERENERGY GridPacks use solid-state sodium chloride battery technology, developed in collaboration with the German Fraunhofer IKTS. Unlike traditional lithium-ion batteries, CERENERGY batteries are safer, flame retardant and made without lithium, cobalt or copper, reducing exposure to volatile commodity markets. The technology’s durability and ability to operate in extreme environments make it ideal for renewable energy applications.
Altech, based in Perth, Australia, focuses on advanced battery technologies and materials. The company’s CERENERGY batteries are intended for grid energy storage, while the Silumina Anodes project is aimed at the electric vehicle market. Altech plans to establish a 120 MWh CERENERGY production plant in Saxony, Germany, and is developing an 8,000 tpa silumina anode plant in the same region.
Altech Batteries CEO Iggy Tan said: “This second letter of intent means that the first two years of production have been fully allocated and we are on track to establish CERENERGY as the standard for safe and sustainable energy storage “.
