Geo40

Geo40 is a pioneering New Zealand-based cleantech company that specializes in the sustainable extraction of valuable minerals from geothermal fluids. By leveraging proprietary technology, the company recovers silica and lithium from geothermal brines, providing a dual benefit: it produces high-value, low-carbon mineral products while simultaneously reducing silica scaling in geothermal power infrastructure, which enhances the efficiency and longevity of renewable energy assets. Founded in 2010, the company has successfully transitioned from research and development to commercial-scale operations, establishing the world's first commercial plant for silica extraction from geothermal fluids at the Ohaaki site. With a strong focus on environmental, social, and governance (ESG) principles, Geo40 is actively expanding its footprint in the global lithium market, targeting the growing demand for electric vehicle battery materials. Their innovative approach to mineral recovery positions them as a key player in the circular economy, turning geothermal waste streams into sustainable industrial resources.

Geo40 aims to be a successful, sustainable, international mineral extraction company that economically extracts valuable minerals from geothermal brines and other mineralized fluids in a clean, green, and environmentally friendly manner.
