Daoud, Yokohama, Yoshizuka Table 3: geothermal water composition ( mg/kg) Assal 3, Assal 4 , Assal 5 and Assal 6. 7. Conclusion Removal of silicic acid is a crucial step before recovery of Lithium. Adsorption column experiment by λ-MnO2 is one of the most economical Li separation methods and its efficacies of 96%. We can be concluded that: granule λ-MnO2 can be used successfully for recovery of Li from geothermal brines. Assal geothermal wells are significantly rich in mineral to be potentially economically viable. economical metal extraction, such as Lithium in Assal could have a positive impact on the exploitation of geothermal energy by reducing the cost. An evaluation study would be necessary to revalue a second time geothermal fluids and the salars of Assal to exploit marketable by-products: economically profitable minerals. ACKNOWLEDGMENTS In this study, I would like to express my great gratitude to Kyushu University, JICA and ODDEG for the opportunity to participate in six months of 2019. I am greatly sincerely indebted to my supervisor, Prof. Yokoyama of Kyushu University and Prof. Kazuharu Yoshizuka of The University of Kitakyushu. I am very grateful for their help, Patience, availability and confidence. What is unforgettable is the time they offered me by answering my questions. I would also like to thank to Prof. Ryuichi Itoi and Dr. Tatsuto Ino for their guidance, time and Consulting REFERENCES Asdrúbal Valencia Giraldo, La era del Litio, Revista Columbiana de Materiales (2016) No9, 1- 14.

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.
