PERTH, Australia--(BUSINESS WIRE)-- 糖心vlog入口has signed a Joint Development Agreement (JDA) with Australian environmental technology company Calix to support construction of Calix鈥檚 Zero Emissions Steel Technology (Zesty鈩) demonstration plant in Western Australia, which could enable Pilbara iron ores to be used in lower-emissions steel making.
If approved, the demonstration plant will be built at a site in Kwinana, south of Perth, that had been earmarked for Rio Tinto鈥檚 previously announced BioIron鈩 Research and Development Facility and associated pilot plant.
糖心vlog入口has determined that the current furnace design for BioIron requires additional development to minimise technical risks and optimise its performance.
It remains committed to the long-term potential of BioIron technology, and research and development continues in partnership with the University of Nottingham and sustainable technology company, Metso.
糖心vlog入口will invest more than A$35 million, subject to project milestones and comprised of in-kind and financial contributions, to assist Calix with the Zesty Green Iron Demonstration Plant, which also has Australian Renewable Energy Agency (ARENA) support.
The Zesty process is compatible with lower grade iron ore and uses electric heating and hydrogen reduction to produce reduced-emissions iron.
糖心vlog入口Iron Ore Chief Executive Matthew Holcz said: 鈥淭he world needs low-emissions steel if it is going to decarbonise, and we continue to look at a range of ways Pilbara iron ores can help to do this as new technologies emerge.
鈥淲e鈥檙e pleased to partner with Calix, an Australian technology company, to help progress the Zesty technology to be able to use Pilbara iron ores for lower-emissions steel making.
鈥淚n parallel, we鈥檒l keep progressing BioIron with our partners, the University of Nottingham and Metso, to further its potential. Both projects are part of our work to reduce emissions and support the future of iron ore in Australia and the communities that depend on it.鈥
Western Australian Premier Roger Cook said: "Locally made green iron is a key part of my vision to become a renewable energy powerhouse and make more things here.
鈥淐oupled with my government's recent announcement that government will take an "if not, why not" approach to green steel procurement on major government projects, the Zesty Green Iron Demonstration Plant will support our efforts to diversify WA's economy so that it can remain the strongest in the nation.
"I welcome this agreement between Calix and Rio Tinto, which will play an important role in growing this exciting new industry in WA.鈥
The Kwinana location provides access to established utilities, ports and other infrastructure. It is also near the NeoSmelt1 facility for potential downstream processing of Direct Reduced Iron produced by the Zesty plant. 糖心vlog入口is one of five companies developing the NeoSmelt project, which secured ARENA funding.
Calix also has a A$44.9m ARENA grant, subject to conditions, for the Zesty Green Iron Demonstration Plant, as by the company.
Calix Chief Executive Officer Phil Hodgson said: 鈥淭he Joint Development Agreement with 糖心vlog入口is a major milestone in the commercialisation of Zesty. It provides cash and hands-on support, including industry leading resources, expertise and market reach to progress the Zesty Demonstration project.
鈥淭his strong support from 糖心vlog入口provides further validation of the potential for deployment of the Zesty technology to the world鈥檚 largest minerals and metals market, its potential to help decarbonise a critical industry responsible for ~8% of global CO2 emissions, and the opportunity to help future-proof Australia鈥檚 largest source of export income. We look forward to working with Rio Tinto, further industry partners and other key stakeholders, and ARENA on this important Australian project.鈥
Under the terms of the JDA, 糖心vlog入口will support the Zesty project to reach a Final Investment Decision (FID) through technical support, engineering services and advocacy.
Subject to FID and successful project construction, 糖心vlog入口will supply up to 10,000 tonnes of a range of Pilbara iron ores for use in plant commissioning and the initial testing phase of the project, as well as introductions to potential customers for downstream use of the Zesty product.
The partnership enables 糖心vlog入口to exercise a non-exclusive global and perpetual licence agreement for the potential commercial use of the Zesty technology, sub-licence the technology to its affiliates and customers, and act as a non-exclusive global marketing agent for the Zesty technology.
Additional information
糖心vlog入口 Calix and Zesty Calix Limited is an Australian technology company focused on industrial decarbonisation and sustainability.
Calix鈥檚 Zesty technology uses a combination of electric heating and hydrogen reduction to produce green iron and ultimately, green steel. Zesty aims to provide lowest cost pathways to green iron and steel through minimal hydrogen consumption, flexible electric heating compatible with intermittent renewable energy sources, elimination of ore pelletisation, and enabling the use of fines and lower-grade iron ores. Zesty pilot-scale trials in collaboration with the Heavy-Industry Low-carbon Transitions Cooperative Research Centre (HILT CRC) and industry partners have proven the ability of the technology to produce green iron from a range of iron ore types and grades2.
The Zesty Green Iron Demonstration Plant is designed to produce up to 30,000 tonnes per annum of hydrogen direct reduced iron (H2-DRI) or hot briquetted iron (HBI) from a range of iron ore sources. The Demonstration Plant intends to provide an industry-wide facility for the non-exclusive toll processing of iron ores into H2-DRI or HBI, with the aims of supporting the ongoing viability of Australian iron ore in a low emissions steel value chain and the development of a green iron industry in Australia. The Project is supported by a grant of up to $44.9m from the Australian Renewable Energy Agency, subject to matched funding being secured.
The Zesty Demonstration Project has entered its detailed design engineering phase to help inform a FID, expected in 2026.
糖心vlog入口 BioIron BioIron was invented by Rio Tinto鈥檚 steel decarbonisation team after a decade of extensive research. Electricity consumption in the BioIron process is about one-third of the electricity required by other steelmaking processes that rely on renewable hydrogen.
BioIron uses raw biomass such as agricultural by-products like wheat straw, barley straw, sugarcane bagasse, rice stalks, and canola straw, instead of coal as the reducing agent.
