Advanced Vanadium Redox Flow Batteries
The future of Energy Storage is here
TAM Energy offers the most cost effective Vanadium Redox Flow Battery solutions.

Brief History

TAM Holdings is a subsidiary of:
Technology & Mineral Holdings (Pty) Ltd and powered by the Gideotech Group of companies.

Mr. Gideo van der Merwe (Inventor & Founder of Gideotech) had the vision to develop a sustainable energy storage business with a primary focus on vanadium redox flow battery (VRFB) technology.

As is evident in the history of vanadium, the mineral has been subject to severe fluctuation in price over the past decade. Such price fluctuations have seen several VRFB startups disappear as high vanadium prices make such batteries to expensive.

This motivated TAM Holdings to search for and acquire the cheapest vanadium resource it could find and TAM today owns a vanadium resource in excess of 21 million tons of Fe-Ti-V, already stockpiled as a Calcine facility.

The acquisition of this resource didn’t come without severe challenges, however, we have stood fast, invested significantly and developed what we believe to be unique processes and technologies to beneficiate our resources, while simultaneously solving significant environmental problems in our area.

We believe that we now have the cheapest resource of its kind known in the industry and are excited about commercialising our projects.
