Pilot Scale Recovery of Lithium from Geothermal Brines (REVISED SITE)
Document Type
NOE - Notice of Exemption
Document Description
This project will demonstrate a pilot scale integrated process for the recovery of lithium from geothermal brines. Skid based process equipment will be designed and assembled for demonstration and housed inside a research facility in Sunnyvale. Lithium carbonate will be produced from synthetic brine and geothermal brine at a peak flow of 10 LPM. Geothermal brine will be transported to the facility. Compared to traditional methods of Li recovery from brines, the proposed high-capacity selective sorbent and its regeneration process is expected to lower the cost of Li production by enabling online separation with high recovery efficiency, and minimizing processing time.

Categorical Exemption
Type, Section or Code
Cal. Code Regs., tit 14, § 15301
Reasons for Exemption
This project is exempt under Cal. Code Regs., tit 14, sec 15301 because it involves skid mounted equipment that will be used to demonstrate the process operation in an existing facility. The skid mounted equipment will be operated in an existing research facility. Operation of this equipment at the facility will involve negligible or no expansion of the existing or former use. Such activities are permitted under the local jurisdiction. No additional permits are required for the proposed activities.
