This initial demonstration at laboratory scale validates the new sorbent and lithium recovery process. Additional work still needs to be performed to (1) demonstrate sorbent durability over thousands of hours of operation at variable temperatures, and (2) scale-up the process to a skid-mounted system for lithium extraction. Process operation at specific sites will help to identify any brine pre-treatment needed before lithium extraction. The estimated production cost of lithium carbonate for a 20,000-ton-per-year plant is less than $4,000 per ton and therefore competitive with that of traditional processes, such as mining and evaporation. Technology/Knowledge Transfer/Market Adoption (Advancing the Research to Market) SRI International’s lithium-extraction process is based on a patent pending, selective, low-cost, and reusable sorbent processed in the form of microporous beads that allow rapid and selective capture of lithium ions from brines. The sorbent is then regenerated to produce lithium carbonate. SRI International’s technical and business development project staff worked closely to promote outreach of the newly developed process with the public and commercial entities. The team planned public outreach by online dissemination of project information and presenting technical progress to geothermal stakeholders at appropriate scientific meetings. SRI International’s webpage highlighted the project (https://www.sri.com/work/projects/lithium-recovery-geothermal-operations). In 2018, SRI International presented a paper on the technology developed under this contract at the 43rd Workshop on Geothermal Reservoir Engineering at Stanford University held on February 12 – 14. The paper entitled “Selective Recovery of Lithium From Brines” was published online in the workshop proceedings shortly after the workshop ended. SRI International filed two pending patents that cover the lithium-extraction process technology: “Metal ion extraction from brines” and “Concentrating lithium carbonate after regeneration of lithium sorbent,” in 2017 and 2018 respectively. The lithium-extraction technology was licensed for commercialization to ExSorbtion, Inc. which intends to further develop this technology with the demonstration of a skid-mounted system for the extraction of lithium from various brine sources, including geothermal brines. Benefits to California The technology will lower the cost of geothermal production by coproducing lithium carbonate from geothermal fluids. It is estimated that the Salton Sea Known Geothermal Resource Area can produce more than 600,000 tons per year of lithium carbonate with a value of $7.2 billion based on the lithium carbonate price of $12,000 per ton. Developing additional geothermal energy sources is an important part of the Imperial Irrigation District’s Salton Sea Restoration and Renewable Energy Initiative and will provide environmental benefits to the region, including reduced greenhouse gas emissions. Revenue from the land leases and mineral recovery is expected to support restoration projects, which some sources estimate may cost between $3 billion and $9 billion. 3PDF Image | Selective Recovery of Lithium 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)
