The Australian Renewable Energy Agency (ARENA) has allocated $44.9 million to Calix to establish a demonstration plant utilizing its Zero Emissions Steel Technology (ZESTY). This innovative plant powered by renewable electricity and hydrogen aims to produce up to 30,000 tonnes of low-carbon hydrogen direct reduced iron (HDRI) and hot briquetted iron (HBI) annually, marking a significant advancement in sustainable steel production. ZESTY, incorporating Calix's proprietary Flash Calciner technology, seeks to drive down the expenses associated with green iron production while demonstrating operational flexibility to align with renewable energy availability. The funding from ARENA not only builds upon successful engineering studies for the demonstration plant but also supports preliminary engineering assessments for a larger commercial ZESTY plant, contributing to the development of local capabilities in low-emission metal production—a strategic focus area for ARENA and a vital industry for Australia's future. Additionally, the project will exhibit a versatile green iron process capable of adjusting production levels in accordance with renewable energy supply, thereby fostering a smarter and cleaner industrial landscape. ARENA CEO Darren Miller emphasized the importance of finding environmentally friendly pathways for steelmaking due to its substantial impact on global emissions. Australia's pivotal position as the largest iron ore producer and exporter underlines the significance of reducing emissions throughout the steel value chain. ZESTY represents a significant stride towards establishing a low-emission steel sector domestically, with the potential to target both local and international markets as the world shifts away from fossil fuels. Calix CEO Phil Hodgson expressed his appreciation for the funding, highlighting the transformative potential of green iron in addressing challenging emissions sources while enhancing the value of Australia's primary export. ZESTY's design focuses on achieving cost-effective operations by minimizing hydrogen usage, eliminating the need for pelletisation, and efficiently operating on inexpensive electricity. Founded in 2005, Calix stands out as an Australian pioneer in sustainable high-temperature mineral processing, with its innovations spanning various industries including steel, cement, alumina, lithium, and critical minerals.
