Special report: Work has begun on Protean Energy’s biggest battery to date: a 1MW/4MWh vanadium redox flow battery in South Korea.

Protean Energy’s (ASX:POW) 60 per cent-owned subsidiary in the country, KORID Energy, has started working on the $9.7 million battery project.

The project is in partnership with the Korean Institute of Energy Technology Evaluation and Planning (KETEP), and Protean’s part to play is with its patented V-KOR stack technology.

The V-KOR stack technology is an energy storage system that stacks a series of repeating cell frames to form a number of cells within the overall battery stack – improving battery performance and lowering manufacturing costs, compared to conventional VRFB technology.

KETEP is administering the project and the grant, as the V-KOR stack technology will be integrated into a broader a 1MW/4MWh vanadium redox flow battery (VRFB).

KORID is focused on developing its battery stack technology for large-scale electricity grid battery installations so the start of the KETEP 1MW/4MWh battery is a significant milestone for the company.

IP from the project will be available to KORID to use to further develop the V-KOR battery technology.

Protean (ASX:POW) also owns a stake in vanadium and uranium exploration projects in South Korea, as it seeks to become a fully vertically integrated resource-to-battery company.
