A memorandum of understanding (MoU) was signed to leverage technologies for green hydrogen energy applications for pyrometallurgical equipment to support lithium chemical conversion processes.

The technology is said to have the potential to be integrated into Infinity’s San José Lithium Project in Spain, as well as Infinity GreenTech novel lithium hydrometallurgical conversion processes.

The companies will conduct a pilot at the new tk BU Mining Hydrogen Burner installation in Germany. The programme will include assessing San José feedstock, as well as using green hydrogen to power a rotary kiln.

Infinity CEO and managing director Ryan Parkin said: “The ability to be at the forefront of this global leading application of green hydrogen has wide-ranging implications for the Company and the industry.
