EnergySource’s proposed 16,500 mt/yr LCE output is equivalent to current U.S. annual demand reported by the USGS (<16,000 mt LCE; Jaskula 2020), and it represents only part of the Salton Sea lithium resource (15 million mt; Chao 2020). Salton Sea geothermal power plants had throughput in 2019 equivalent to 127,750 mt LCE (121,308,148 mt with average lithium concentration of 200 mg/L). Figure 5 shows the process steps for production of lithium carbonate based on EnergySource’s patented process (Marston and Garska 2019). Figure 6 shows and describes the details of the continuous countercurrent adsorption and desorption part of the lithium extraction process. Description of process steps: 1000: liquid brine from power plant operations; 1026: atmospheric flash of post-crystallizer brine slurry; 1028: reactor clarifier precipitates silica; 1030: secondary clarifier removes suspended solids; 1036: liquid separated from solids via horizontal belt filter with vacuum and filter cloth with pH 1 HCl acid wash to remove lead and pH 9.5 condensate wash to remove HCl; 200: DLE process; 1038: polished brine from secondary clarifier; 300: impurity removal; 302: reaction tank to facilitate removal of iron and silica; 310A: limestone slurried with brine to maintain pH 5.5; 310B: air injection to oxidize iron; 304: clarifier with flocculent added to remove iron and silica; 314: Fe/silica filter cake; 306: secondary reactor tanks to facilitate metals removal (mainly Zn, Mn); 312A: limestone slurried with brine to maintain pH 8; 310B: air injection to oxidize iron; 308: secondary clarifier precipitates Zn, Mn oxide/hydroxides; 316: Zn, Mn filter cake; 318 – HCl added to lower pH to 4.5-6; temperature 5C-100C; 16 This report is available at no cost from the National Renewable Energy Laboratory (NREL) at www.nrel.gov/publications.PDF Image | Lithium Extraction from Geothermal Brines

Product and Development Focus for Infinity Turbine
ORC Waste Heat Turbine and ORC System Build Plans: All turbine plans are $10,000 each. This allows you to build a system and then consider licensing for production after you have completed and tested a unit.Redox Flow Battery Technology: With the advent of the new USA tax credits for producing and selling batteries ($35/kW) we are focussing on a simple flow battery using shipping containers as the modular electrolyte storage units with tax credits up to $140,000 per system. Our main focus is on the salt battery. This battery can be used for both thermal and electrical storage applications. We call it the Cogeneration Battery or Cogen Battery. One project is converting salt (brine) based water conditioners to simultaneously produce power. In addition, there are many opportunities to extract Lithium from brine (salt lakes, groundwater, and producer water).Salt water or brine are huge sources for lithium. Most of the worlds lithium is acquired from a brine source. It's even in seawater in a low concentration. Brine is also a byproduct of huge powerplants, which can now use that as an electrolyte and a huge flow battery (which allows storage at the source).We welcome any business and equipment inquiries, as well as licensing our turbines for manufacturing.CONTACT TEL: 608-238-6001 Email: greg@infinityturbine.com (Standard Web Page)
