Gagne et al., The Potential for Renewable Energy Development to Benefit Restoration of the Salton Sea: Analysis of Technical and Market Potential Technical Report NREL/TP-7A4. Extraction of lithium from geothermal brines from the Salton Sea area is of great interest because their lithium concentrations are as high as 400 mg/L. Furthermore, Salton Sea KGRA geothermal brines contain other salable metals such as manganese, zinc, and potassium. Geothermal brines have several characteristics that present challenges for any process that aims to recover lithium in an economical fashion: • Very large volumes of brine are processed. Any lithium recovery process that requires pre-treatment of the brine or chemical modification of the entire brine flow is likely to require large quantities of consumable reagents, which are relatively expensive. Even simple processes like heating or cooling the brines may be costly. 6PDF 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)
