Wastewater startup Gradiant is launching a new company, alkaLi, to extract lithium from brine rather than mining it from rock. This new venture aims to meet the growing demand for lithium, which is essential for powering the world’s electric vehicles. The process is expected to be more efficient and environmentally friendly than traditional methods of lithium extraction. Gradiant has already established itself as a leader in industrial wastewater treatment, with customers including major companies like TSMC, Pfizer, and Coca-Cola.
Founders Prakash Govindan and Anurag Bajpayee started Gradiant in 2012 based on their research in water purification at MIT. The company has since developed technologies for removing contaminants like PFAS and extracting lithium from brine. The new venture in lithium extraction is a promising offshoot of Gradiant’s core operations, which have already reached a $1 billion valuation. With over 1,000 installations for water treatment, Gradiant is well-positioned to expand its business into the lithium market.
The process developed by Gradiant for extracting lithium from brine involves using resins and membranes to concentrate the mineral. This method is faster, more efficient, and less harmful to the environment compared to traditional methods that rely on evaporation ponds. The company claims that its technology has 50% lower operating costs than other methods of lithium extraction. This could potentially reduce the United States’ reliance on China for lithium, making the country more independent in meeting its demand for the critical mineral.
While lithium prices have decreased in recent years, long-term demand is expected to increase as the shift towards electric vehicles continues. By 2030, over 60% of new vehicles sold in the U.S. are projected to be plug-ins or hybrids. Gradiant’s decision to start the business during a period of low prices could prove to be beneficial in the long run, as it allows for the development of technology and products in anticipation of future demand. The company believes that there is a growing market for its technology as the world transitions towards a more sustainable energy future.
Gradiant’s new venture into lithium extraction presents an opportunity to revolutionize the way this critical mineral is sourced. By focusing on brine extraction rather than traditional mining, the company hopes to create a more sustainable and cost-effective method of meeting the increasing demand for lithium. With its proven track record in industrial wastewater treatment, Gradiant is well-equipped to succeed in the lithium business and potentially reduce the global reliance on China for this essential mineral. The company’s innovative approach has the potential to reshape the future of lithium production and contribute to a cleaner, more sustainable energy industry.
