UofC advances large-scale energy storage tech with CellCube vanadium redox flow battery delivery

CellCube Energy Storage Systems Inc. has delivered a vanadium redox flow battery (VFB) to the University of Calgary to advance the research on the production of vanadium and vanadium electrolytes (VE).

Electrode materials for redox flow batteries are being developed in collaboration with other researchers at the university. The goal is to develop low cost vanadium redox flow battery systems that are able to operate efficiently at high current densities, improving the economic viability of the technology.

The systems are being developed for large scale energy storage and the integration of renewable electricity generation.

Over 130 such batteries have been installed by B.C.-based CellCube around the world with some VFB operating for close to 10 years.

Ted Roberts, professor and associate head (Research), Department of Chemical and Petroleum Engineering at the University of Calgary and an expert and innovator in the field of electrochemical technology, will head the research team. Roberts' research group is exploring the use of new large-scale energy storage technologies.

Cellcube recently acquired the research and technology company Pure Vanadium Corp., which is involved in the development of VE formulations for grid-scale electrical storage batteries. High quality VE is a key component of vanadium redox flow batteries.

The goal of the research is to test VE formulations in the electrical storage system. Currently, VE is approximately 30-40 per cent of the cost of the storage battery.

"One of the key elements of our corporate strategy is to refine the VE formula to make it more economical for vanadium redox flow batteries," Mike Neylan, CEO of Cellcube, said in a statement. "Cellcube's association with the University of Calgary will advance the work to commercialize the scientific technology developed by Pacific Northwest National Laboratory and licensed by Cellcube through its subsidiary Pure."

Formerly Stina Resources Ltd., the company changed its name to Cellcube Energy Storage Systems Inc. in May to reflect its new strategic focus on full vertical integration in the energy sector, from vanadium exploration and production through to the manufacturing and sale of vanadium redox flow batteries.

While the CellCube product line-up with “plug’n play ready” containerized systems is available today, the company said it expects to soon release a next generation of flow battery modules to challenge competing technologies in the electrochemical storage space.
