Monsters of Rock: Could this Australian company’s ZESTY technology crack the green steel equation?

There’s a new Australian player in Green Steel Space who has nothing to do with Andrew Forrest.

Calix is ​​a favorite of ESG investors in Australia and around the world and has grown by more than 600% in the past 12 months due to growing excitement for its low emission lime and cement technology, LEILAC.

This is a calcination process in which the CO2 emissions are c -tured when they are released from raw limestone, which avoids between € 14 and € 24 per tonne of CO2 in cement production.

It’s now worth $ 1.2 billion, up 20% to $ 7.34 per share yesterday after it was announced it filed a patent  -plication for its core furnace technology to make iron.

This has called it the Zero Emissions Steel TechnologY process, or ZESTY.

The not-so-well-kept secret of steel production is that around 1.8 t of CO2 are produced per ton of pig iron produced in the blast furnace process.

The steel industry accounts for around 8% of global CO2 emissions.

Steel can be made using a direct reduced iron process, a form that the Swedish Hybrit consortium used on renewable hydrogen to make the world’s first “green iron” for delivery to car manufacturer Volvo.

Calix says that this still requires generating a large amount of hydrogen for every ton of iron to be produced, and that iron ore fines must first be pelletized to minimize loss, which makes the process (and other forms of DRI that use natural gas) expensive .

Calix claims that his technology would be able to reduce iron ore to iron in a hydrogen atmosphere between 600 and 80 ° C, about 1000 ° C lower than a normal blast furnace, and could be electrically heated, meaning it could be powered by renewable energy could be operated.

The company says hydrogen would only be consumed as a fuel and not as a reductant, which lowers input costs and avoids the need to pellet iron ore fines first.

Initial tests of the Calix process are underway at Imperial College London, with Calix planning to expand the tests in its Bacchus Marsh facility in Australia if successful.

“These are the early days for Calix ZESTY technology, but given the essentiality of both the potential of our technology in iron and steel production and the size of the environmental challenge, which is similar to the challenge facing our LEILAC business, we are becoming this opportunity so quickly as much as possible – the world can’t wait any longer, ”said Phil Hodgson, CEO of Calix.

The race for green steel production is on, but the field has its doubters. BHP Chairman Ken Mackenzie, whose company sold its 80 percent stake in BMC’s Queensland coal mines to Stanmore Coal (ASX: SMR) this week, told shareholders at yesterday’s general meeting that coal would be in the Steel making process would be used.
