1 Adionics SAS, registered at Paris R.C.S. under n with registered Head Office at 103 rue de Grenelle, Paris, France. GEOENERGY DAYS 3rd 5th JULY 2018, PAU - FRANCE Guillaume de Souza, Founder

2 OUR VISION: VALORISE AQUEOUS BRINES A disruptive technology allowing selective salt recovery from saline water opens new perspectives: Valorisation and recycling of rare and high value salts, Customized production of desalted water from brine, even with very high TDS. An objective to Promote Circular Economy and reduce Environmental Footprint. Adionics has entered the Global Cleantech 100 list 2017 It gathers companies most likely to have big commercial impact in a 5-10 year timeframe. 2

3 BRIEF COMPANY INTRODUCTION Founder: Previously Gas Separation Expert (at Air Liquide) 2008: Guillaume de Souza MSc UPMC Sorbonne (Paris) ENSTA ParisTech Engineering Degree Air Liquide Group Expert ( ) Author & co-author of 31 Patents Author of 2 publications in French Engineering Tech. Encyclopedia P. Peters CEO : Lab. support at ECP Adionics Founded in March 2012 Key technology co-developers CEO : Patrick Peters (ex Ovive & Suez) B. Dautriche Process D. Mabire VP R&D J. Pouessel Chemist J.M. Grassot Chemist 4 PhD 2 MSc 3

4 ADIONICS TECHNOLOGY : NEW & INVENTIVE FOR INDUSTRY LL Extraction Formulation Associated Process Mixing allows salt transfer from water to the solvent, Flionex. Saline feed water Deionized water Concentrated hot brine Low flow = High Salt Concentration Regeneration Hot water (Saline or not) Salt transfer is reversed when water and solvent are heated. 4

5 FLIONEX : PRINCIPLES OF SALTS EXTRACTION «A World Exclusivity» Complexation of the cation thanks to a neutral organic macromolecule making it hydrophobic => transfer to the organic layer The anion follows by charge neutrality and by employing a specific matrix which solvates the anion (SA) Salt desorption at higher temperature (> +50 C) to regenerate Flionex and produce brine Li + Cl - 3 Aqueous phase 1 Extraction 2 Li+ Cl - SA + SA Organic phase = Flionex 5

6 LET S JUMP FROM 2D TO 3D DESALINATION! NaI : 50 $/kg NaBr: 2.5 $/kg LiCl: 5 $/kg 6

7 APPLICATION TO MIXER-SETTLER TECHNOLOGY One mixer/settler = one stage of extraction M S Effluent after treatment without the extracted ionic compounds Legend Water Trace organic removal units Raw water Regenerated Flionex Loaded Flionex Brine with extracted salt(s) Heat exchanger M S E R Mixer Settler Extraction Regeneration Process sizing: Depends on the project : flow rates, ion concentrations, Product purity Technical/economical selection. Added Mixer/Settlers: Increases Li recovery rate Increase of Li brine concentration 7

8 LITHIUM SELECTIVE EXTRACTION EXAMPLE 1 Test conditions : Volume ratio 1/1 water and fresh Flionex Ion [Initial] Aqueous (mg/l) [Equilibrium] After extraction (mg/l) Extraction Rate at 20 C Na % K % Ca % Mg ,3 1.1% Li % In one extraction stage : Na/Li ratio : from 60 to 3 in one extraction stage! 54% of Lithium extracted! Cl % Br % Lithium extraction: Up-to 90% High Lithium selectivity Production cycle < 30 minutes No magnesium, sulfates, potassium or boron extraction System designs show > 90% Lithium recovery Lithium reconcentration factor in produced brine x 5 to 20 Sodium is the main impurity but level is controled by system s design 8

9 LITHIUM SELECTIVE EXTRACTION EXAMPLE 2 Tested water : reconstitued ATACAMA water Test conditions : Volume ratio 1/1 water and fresh flionex In one extraction stage : High selectivity! 28% of Lithium extracted! Lithium extraction: Up-to 95% 9

10 A PROVEN TECHNOLOGY Salts extraction proven Salts extraction efficient *TRL = Technical Readiness Level Achievable pilot for other application on demand 2015, TRL , TRL , TRL /16 : Masdar with 1st demonstrator in UAE Application : Sea water desalination June 2018 : Industrial prototype (Martigues, Fr) Industrial water production Next steps: On-site selective Lithium or Iodide salt Extraction containerized systems 10

11 A PROTOTYPE IN MARTIGUES (FR) A containerized system Quick installation, Plug & play 50 to 100 m 3 /d feed water NaCl extraction from sea water Mixer-Settlers for maximum flexibility & test feed back 11

12 ENVIRONMENTAL BENEFITS Guarenteed Clean Air - No emissions in the atmosphere Water - No water evaporation, no loss to atmosphere - 100% of treated water is recovered for recycle Solvent - Safe and reliable, Water treatment before discharge - Trace organic removal - Coalescer membrane or other, - Local Regulation dependent. Excellent Energy Efficiency : A+ - Thermal Energy : around 7 kwh th /kg LiCl - Electrical energy : < 2 kwh elec /kg LiCl 12

13 VALUE PROPOSAL Industrial process : less than 30 min High TDS favors Lithium extraction Low water consumption Clean effluents : matches with European regulation Low energy consumption High Salt extraction rate Possible application on K, Sr, Ba High Salinity Li brine produced High cost reduction No extraction of Potassium, Boron, Magnesium or Sulfate 13
