We are Grin Power. Our mission is to be a leading supplier of clean battery-grade lithium for the global energy transition.
By advancing Direct Lithium Extraction (DLE) technology, powered by renewable energy, we aim to be a leading supplier of ‘green’ lithium to the EV and battery manufacturing market.

Operating in the heart of
the ‘Lithium Triangle’, the world’s largest reserves of lithium.
We own licences across four key areas, totally over 1250 km2 in Chile to explore and develop. Our flagship project Laguna Verde is considered highly commercial at the JORC resource estimates provided, with 1.63 mt equating to a multi-decade production opportunity.
Lithium is the critical component for the 21st century to reach net-zero targets and move to decarbonised economies.
The unprecedented demand for lithium means it must be sourced, produced and refined with the lowest environmental impact and in the interests of all stakeholders. DLE has this advantage when it comes to sourcing lithium and why we call it ‘green’ lithium.

The Chilean government is prioritising sustainable technologies for all new lithium projects.
The Government wants to accelerate commercial production, setting a target to have new lithium projects operational by 2026.
The need for lithium is forecast to increase 20x over the next 20 years. CleanTech will play an important role in meeting this worldwide demand.
