Altech Chemicals Limited (ASX:ATC) (FRA:A3Y) is excited to announce that it has executed a Joint Venture Shareholders' Agreement with world-leading German battery institute Fraunhofer IKTS ("IKTS") to commercialize IKTS' revolutionary CERENERGY(R) Sodium Alumina Solid State (SAS) Battery. Altech, inclusive of associated entity Altech Advanced Materials AG, will be the majority owner at 75% of the JV company, which will commercialize a 100 MWh project to be constructed on Altech's land in Schwarze Pumpe, Germany. The SAS CERENERGY(R) battery uses common table salt and ceramic solidstate technology.


Altech believes that Sodium Alumina Solid State (SAS) CERENERGY(R) batteries are the game-changing grid storage alternative to lithium-ion batteries. CERENERGY(R) batteries are fire and explosion-proof, have a life span of more than 15 years and operate in extreme cold and desert climates. The battery technology uses table salt and nickel - is lithium-free; cobalt-free; graphite-free; and copper-free, eliminating exposure to critical metal price rises and supply chain concerns.

The SAS technology has been developed by Fraunhofer IKTS over the last eight years and has revolutionized previous technology, allowing higher energy capacity and lower production costs. SAS-type batteries, in terms of capacity, have already been successfully tested in stationary battery modules. The IKTS SAS batteries are in the final phase of product testing and ready to commercialise. IKTS has spent in the region of EUR 35 million on research & development and operates a EUR 25 million pilot plant in Hermsdorf, Germany. The final CERENERGY(R) battery modules, at 10 KWh each, are specially designed for the grid storage market and have been undergoing extensive performance testing in Germany. These modules are designed to fit in racks housed in sea containers that can be deployed for grid storage.

IKTS has been looking for an entrepreneurial partner that has German land available, has access to funding, is a builder of projects, has battery background, and has technology in alumina used in ceramics.

Altech fitted the criteria, and the Joint Venture Shareholders' Agreement was executed. Altech group will own 75% of the project with IKTS 25% free carried. The intellectual property will be licensed exclusively to the joint venture.

The joint venture partners have elected to develop a 100 MWh SAS battery plant (Train 1) on Altech's site in Saxony, Germany. The target market for this project will specifically focus on the grid (stationary) energy storage market which is expected to grow by 28% CAGR (Compound Annual Growth Rate) in the coming decades. The global grid energy storage market is expected to grow from USD 4.4 billion in 2022 to USD 15.1 billion by 2027. Or further out, the market is expected to grow from 20 GW in 2020 to over 3,000 GW by 2050. Altech believes that SAS batteries can provide high security, at low acquisition and operating costs, for the stationary energy storage market.

The proposed battery plant will produce 10,000 SAS battery modules per annum, rated at 10 KWh each. These SAS battery modules are expected to sell for between EUR 7,000-9,000 per module, or EUR 700-900 per KWh, at final pack costs. IKTS has estimated that the total cost of production for CERENERGY(R) batteries will be 40%-50% cheaper than lithium-ion batteries.

The joint venture partners have commenced the planning process for the Bankable Feasibility Study required for the commercialisation process. Once the Train 1 (100 MWh) plant is built and operating, the longer-term vision for the joint venture is to construct additional trains or a Gigawatt battery facility.

About Altech Chemicals Ltd

Altech Chemicals Limited (ASX:ATC) (FRA:A3Y) is aiming to become one of the world's leading suppliers of 99.99% (4N) high purity alumina (Al2O3) through the construction and operation of a 4,500tpa high purity alumina (HPA) processing plant at Johor, Malaysia. Feedstock for the plant will be sourced from the Company's 100%-owned kaolin deposit at Meckering, Western Australia and shipped to Malaysia.

HPA is a high-value, high margin and highly demanded product as it is the critical ingredient required for the production of synthetic sapphire. Synthetic sapphire is used in the manufacture of substrates for LED lights, semiconductor wafers used in the electronics industry, and scratch-resistant sapphire glass used for wristwatch faces, optical windows and smartphone components. Increasingly HPA is used by lithium-ion battery manufacturers as the coating on the battery's separator, which improves performance, longevity and safety of the battery. With global HPA demand approximately 19,000t (2018), it is estimated that this demand will grow at a compound annual growth rate (CAGR) of 30% (2018-2028); by 2028 HPA market demand will be approximately 272,000t, driven by the increasing adoption of LEDs worldwide as well as the demand for HPA by lithium-ion battery manufacturers to serve the surging electric vehicle market.
