Lithium Harvest Holding announced a letter of intent on October 13 to form a joint venture for an integrated geothermal power and lithium project in Alberta, Canada. The company does not identify its geothermal development partner in the release. A letter of intent and a proposed joint venture are development steps, not confirmation of a financed facility under construction or in operation.

At full nameplate capacity, the planned project targets approximately 0.67 terawatt-hours of electricity and 28,500 tonnes of lithium carbonate per year. These are annual output targets, not installed megawatts or delivered production. The release describes development in two phases but does not give a separate output schedule for each phase.

First electricity generation and first lithium carbonate production are both targeted for 2028. Progress depends on technical validation, approvals, financing, construction and commissioning. The company explicitly says there is no assurance that the joint venture will be formed, that the facility will be built or that the planned schedule and output will be achieved.

The proposed design uses geothermal heat to generate power and geothermal brine as feedstock for lithium extraction and refining. Lithium Harvest plans to contribute water treatment, direct lithium extraction and refining technology, while the partner would contribute geothermal development capabilities. Those intended roles do not establish demonstrated process performance at this site.

The release estimates potential avoided carbon dioxide emissions of up to 933,000 tonnes per year at full output. It says actual reductions depend on final design, operating performance, displaced electricity and reference scenarios. This is a conditional company estimate, not independently measured emissions savings or a guaranteed environmental result.

Next steps include final joint-venture arrangements, resource and process evaluation, engineering, permitting, commercial agreements and construction financing. The release does not disclose a total project cost or committed financing. Its power, lithium and emissions figures should be read as forward-looking project assumptions rather than current operating capacity or proven production.
