Lithium Ark, a pioneering technology company in the lithium refining sector, has successfully obtained a European patent for its innovative “Ark Loop” process. This proprietary technology is designed to produce battery-grade lithium hydroxide directly from lithium chloride, whether in solution or crystal form. The significance of this patent lies in its ability to simplify the lithium value chain by eliminating the need to produce, transport, and reconvert lithium carbonate, while still allowing for the production of battery-grade lithium carbonate as required by customers.
The Ark Loop process not only streamlines operations but also enhances sustainability. By employing a closed-loop system that recycles potassium and eliminates the need for external reagents, the process contributes to a more self-sustaining refining pathway. According to Peter Ehren, co-founder and CTO of Lithium Ark, the re-engineered refining process results in up to 89% lower carbon emissions, a 75% reduction in water consumption, and a 49% decrease in energy use. Additionally, it can cut operational and capital expenditure costs by up to 50%, facilitating faster and more scalable deployment.
Lithium Ark has also secured patents for its technology in the United States and Chile, making the European patent a crucial milestone as the company progresses towards commercial deployment. The first commercial facility is set to be developed in Antwerp, Belgium, where the Ark Loop technology will be demonstrated at an industrial scale, paving the way for future global expansion.
The naming of the technology as Ark Loop not only reflects its connection to Lithium Ark but also highlights the circular nature of its underlying chemistry. The removal of soda ash from the refining process is a key factor in achieving significant emissions reductions, further solidifying the importance of this innovation in the lithium refining landscape. As Lithium Ark moves closer to commercial deployment, the Ark Loop process is poised to deliver cleaner, lower-cost, and more efficient lithium refining solutions on a global scale.
