How many deployments does CellCube havE?
We have deployed more than 130 CellCube storage systems globally to date.
ARE THEY PILOTS OR ARE THEY COMMERCIALLY ACTIVE?
We started selling CellCube branded ESS systems in 2008. In the following early years, our main focus was on application specific pilot projects. About 30 percent of installed CellCube systems are in early adoption and commercial use.
Since then, CellCube has found continued success in commercial driven BtM projects, primarily in DER applications (mainly EU, Solar plus storage as demand charge and high energy price reduction). We have further systems deployed from Siberia to Vietnam to Australia and South Africa in micro grids (either grid connected or diesel gensets + photovoltaic systems + energy storage hybrids).
On the other hand, our larger unit instalments (200kW to 500kW, 3-8h duration) serve in grid pilot projects at major European utilities (applications: Frequency regulation/Primary Control Reserve, voltage/grid-quality support, capacity market, and community size micro grids). We calculate a combined 3M+ operational hour experience in the installed base.
HOW IS CELLCUBE DIFFERENT FROM COMPETITORS
CellCube is the first miner of vanadium that also packages the material into a storage product. As a vertically integrated energy storage system provider, we function as “one stop shop” for sustainable storage solutions.
is the transfer from Lithium to Vanadium approaching faster than we think?
Yes. The tipping point for commercializing vanadium redox flow batteries is coming earlier than expected.
Energy storage markets are changing from a need for power-centric energy storage in large grid applications (frequency regulation, transmission & distribution grid quality support, etc.) to a much larger energy centric storage market. This includes everything from peaking power conversion to storage, multi-hour DER to off-grid applications. We appreciate recent articles about the peaker plant future in California. Within this context the resource adequacy paradigm strengthens our approach to deliver the flow battery technology from 4-8 or even 10-100 hours as long as the commercial character can be constructed.
CellCube rivals other company's approach towards stationary energy storage market share. In energy centric market segments (like much larger than the size for power centric applications in terms of MWh’s installed) CellCube flow batteries show substantial advantages for long duration storage following down the capacity market segment merit order in price/kWh and demand for more than 4 hour durations, thus making a viable case for flow deployments. The myth about high cost flow batteries should be seriously tested when talking at least about our CellCube offering and I would add that the tipping point for Lithium versus flow might be earlier than expected.
