Open pit hard rock mines for lithium scar the landscape. Once you mine it, the rock has to be roasted with fossil fuels to produce lithium hydroxide. This is very CO2-intensive.
*One tonne of lithium hydroxide produced through hard rock mining requires approximately:
Lithium extraction from brines in South America evaporates large quantities of water in the second driest place on earth. This stresses the environment and local indigenous communities.
*One tonne of lithium hydroxide produced through evaporation ponds requires:
Draws on naturally occurring, renewable geothermal energy to power the lithium extraction process and create a renewable energy by-product. This uses no fossil fuels, requires very little water and has a tiny land footprint.
*One tonne of lithium hydroxide produced through our process requires:
Through wells into the deep sub-surface, hot, lithium-rich brine from our project area is pumped to the surface.
- We will use renewable heat derived from our geothermal brine to drive the lithium extraction process, with no fossil fuel consumption.
- We will produce a surplus of renewable energy, decarbonising the grid.
- We will produce a unique, premium, battery-quality hydroxide product for EVs, zero carbon footprint.
- The spent brine then gets re-injected in a closed-loop cycle.
The EU has set the challenge to industry to decarbonise the production of batteries and EVs, including raw materials. Vulcan is proud to be a first mover and peerless leader in meeting this challenge with our Zero Carbon Lithium™ business.
