Calix green iron tech recognised at UN climate talks

Industrial process technology company Calix has been recognised at the United Nations Climate Change Conference (COP29) in Baku, Azerbaijan, winning the Net-Zero Industries Award for Outstanding Project with its zero-emissions steel technology.

Calix’s Zero Emission Steel Technology (ZESTY) was celebrated for its “success and potential as a lowest-cost solution to green iron and steel production”, according to the company. The ASX-listed comapny describes ZESTY as a “renewably powered hydrogen direct reduced iron” technology, using “minimal” amounts of hydrogen.

The award was presented by Australian energy minister Chris Bowen and Austrian energy minister Leonore Gewessler.

“I hope this award highlights that ‘hard-to-abate’ climate challenges can be solved. Technology solutions are ready to be scaled and deployed,” said Calix Managing Director and CEO Phil Hodgson in a statement on Monday (Australian time.)

“ZESTY’s success has been made possible through our collaboration with industry partners and members of the HILT CRC, coupled with support from the Australian Renewable Energy Agency (ARENA) and the Australian Government.”

According to Calix, the process can produce green iron from multiple ore types. Iron can then be used in conventional blast furnaces for lower carbon steel products or in electric arc furnaces (EAF) for zero emissions steel.
