A global leader of Direct Lithium Extraction (DLE)

GEOLITH DLE technology (Li-Capt®) enables sustainable and local lithium production

Join our team – We are looking for talented & driven people to come work with us.

Energy transition

Energy transition inevitably means energy storage and green mobility, both of which are impossible without lithium. GeoLith is a technological enabler, ensuring that sustainable lithium supply is a reality.

Clean, simple & innovative.

GeoLith’s Li-Capt® technology provides a technological solution to a major problem: Shortages of lithium will jeopardize the energy transition. Thanks to its patented ion exchange technology, sustainable lithium production is now possible, with an extraction process respectful of the environment, without CO2 emissions and generating zero waste. GeoLith is fully committed to the UN Sustainable Development Goals.

To propose an industrial solution for the lithium’s extraction and help countries to respond to the need of the ecological transition by enhancing underground resources in a respect of environment.


To enable local and sustainable lithium production, allowing nations to have sovereign control over their raw materials, and giving them the possibility to succeed the energy transition.

A sustainable & robust technology

Li-Capt® is a technology developed by GeoLith which enables the extraction of lithium from a raw brine and its conversion to a commercial product in just a few hours.
Thanks to a compact and scalable design, it is no longer necessary to transfer brines from pond to pond, nor to transport intermediate products, reducing the related emissions, as well as the footprint of the installation.

Zero Carbon

Our technology has no greenhouse effect emissions.

Zero Waste

Removable and recyclable technology.

Robust and reliable

Proven under pressure and temperature (up to 80°C and 35 bar).

Carrousel operation

Allowing continuous operation.


At a wide range of Li concentrations.

Modular & scalable design

Reduces CAPEX and OPEX and is designed for industrial operation.

Traditional lithium extraction process vs. GeoLith’s DLE technology (Li-Capt®)

Traditional process

GeoLith’s Li-Capt®


20 to 40% lithium capture, and high water losses through evaporation

>90% lithium capture, allowing to source new sustainable brines

C02 emissions

15t CO2 from spodumene production 5t CO2 from brine production

Zero emissions

Waste production

Intensive use of chemicals and consumables

Zero waste, low use of chemicals & recycling of consumables

Production time

2 years from source to commercial product

Hours, from source to commercial product

Respect of water ressources

Water losses in arid regions (lithium triangle in the Andes)

Water is returned to the source once the lithium is captured

Power consumption

Intensive use of machinery and transportation in remote areas

Very low use of power required for the equipment


4 major sectors for GeoLith

Our technology is applicable to all conventional and non-conventional lithium sources around the world.

Geothermal Brines
Geothermal BrinesLi-Capt® Direct Lithium Extraction enables local production of lithium from geothermal brines around the world, leveraging renewable energy and heat from these assets for a fully sustainable production. Its extraction efficiency of more than 95% lithium capture, and its exceptional selectivity have been proved thanks to its pilots in Europe (France, Germany and UK). GeoLith believes in the creation of sustainable lithium ecosystems around Europe, North and South America and everywhere else.

Produced Waters
Produced WatersExisting assets produce great amounts of water containing important concentrations of lithium. These waters, currently treated as a waste, can be valorised thanks to the exceptional performance of Li-Capt®, turning a cost into a revenue. Considerable resources have been identified in Europe, the US, Argentina and several other countries around the world.

SalarsThanks to the exceptional capacity of extraction of Li-Capt® it is now possible to extract lithium without any evaporation, enabling production from high and low concentrated salars, especially in the triangle of lithium (Argentina, Bolivia and Chile). Li-Capt® brings a more sustainable process of lithium extraction, avoiding depletion of the water reservoirs and allowing to valorise waste-fluids.

Battery Recycling
Battery RecyclingImportant amounts of manufacturing scraps are produced in the process of fabrication of batteries for electrical vehicles. GeoLith Li-Capt® technology will allow to recover lithium from them, circularising the manufacturing process and enhancing the sustainability of this essential equipment for the energy transition.
