Description	Rio Tinto partners with Calix to build the Zesty demonstration plant, a green hydrogen-based direct iron reduction process that reduces iron ore using a renewables-powered electric Calix Flash Calciner. This technology reduces the amount of hydrogen needed and removes the need for pre-processing ores into pellets. The plant will produce 30,000 tonnes a year of green iron and is located on Rio Tinto's site in Kwinana, Western Australia.
