Geothermal Thermoelectric Generation (G-TEG) with Integrated Temperature Driven Membrane Distillation and Novel Manganese Oxide for Lithium Extraction Final Report

Published by Southern Research Institute | Department of Energy | Catalog Last Checked: August 03, 2026 at 12:59 AM | Dataset Last Updated: June 01, 2018 at 09:32 PM
This project aims to develop an innovative Geothermal ThermoElectric Generation (G-TEG) system specially designed to both generate electricity and extract high-value lithium (Li) from low-temperature geothermal brines. The process combined five modular technologies including silica removal, nanofiltration (NF), membrane distillation (MD), Mn-oxide sorbent for Li recovery, and TEG. This project provides a proof of concept for each of these technologies. This is the final report from the project. It includes corrections and the final data. The final report supersedes all previous submissions.
