Our Technology & Process

A Proprietary
Low-Carbon Refining
Process

Green Lithium's hard-rock lithium refining process is independently verified to deliver significant CO₂ reductions versus incumbent Chinese refineries, with multiple active R&D programmes targeting further efficiency improvements.

The Process

From Ore to Battery-Grade Chemicals

Green Lithium has developed and patented a hard-rock lithium refining process that converts spodumene concentrate into high-purity lithium chemicals suitable for use in cathode active materials.

Unlike competing processes, our approach does not require any specific ore source and is engineered to produce multiple product grades across independent processing lines - giving our customers and offtakers unmatched supply certainty and specification flexibility.

Our process has been independently verified for CO₂ performance, with active R&D programmes underway on Teesside targeting further reductions in energy intensity.

Key Capability

Feedstock Independence

Our process works across multiple spodumene concentrate sources - not tied to a single mine or geography. We have tested multiple feed materials and hold commercial agreements with suppliers across the global supply chain.

Key Capability

Product Flexibility

Multiple independent processing lines enable simultaneous production of lithium hydroxide and lithium carbonate to varying specification grades, allowing commercial and logistics flexibility across different customer requirements.

Key Capability

Coproduct Revenue

Our patented waste re-processing technology converts process residues into a saleable commercial coproduct with binding offtake commitments in advanced negotiation - generating meaningful additional revenue from material that competitors dispose of at cost.

Development Pathway

A Systematic Programme Approach

Green Lithium is executing a disciplined, staged development programme designed to de-risk the project technically and commercially at each phase before committing to the next.

1
Phase 1 - In Progress

Piloting - Teesside, UK

In-house piloting capability established in Teesside. Process chemistry validated across multiple feedstocks. Sample product produced and characterised. Commercial relationships with feedstock suppliers and product offtakers established.

2
Phase 2 - Planned

Demonstration Plant

UK-based demonstration plant to validate the complete process at meaningful commercial scale. This phase underpins project finance for the commercial facility, generates commercial-scale product samples for offtake negotiations, and provides the engineering data set for the FEED study.

3
Phase 3 - Target

Commercial Facility - 50,000tpa

Full-scale commercial lithium refinery producing 50,000 tonnes per annum of battery-grade lithium chemicals. Target annual revenue of £1bn+. A transformative contribution to European critical mineral security and the UK's industrial base.

Sustainability

A Lower-Carbon Path to European Lithium

Green Lithium's refining process has been independently verified to deliver significant CO₂ reductions compared to the current Chinese refining operations that dominate global lithium chemicals production.

Our Teesside location enables access to renewable energy and industrial decarbonisation infrastructure, and our active R&D programme is targeting further reductions in process energy requirements.

Producing lithium chemicals in the UK and Europe also eliminates the substantial shipping emissions associated with importing finished product from China, contributing further to the overall lifecycle carbon advantage of European-refined lithium.

Independent Verification

CO₂ reduction vs. incumbent Chinese refineries independently verified by third-party technical consultants.

Active R&D Programme

Ongoing research targeting further energy efficiency improvements and integration of renewable energy inputs into the refining process.

Supply Chain Emissions

UK-based production eliminates long-distance shipping emissions, providing a meaningful lifecycle carbon advantage versus imported Chinese product.
