AUSTRALIA-based manufacturer of zinc-bromide flow batteries modules (ZBM) RedFlow has announced it has improved the manufacturability and flexibility of its batteries.

Zinc-bromide flow batteries are said to be ideal for storage of intermittent renewable energy, managing peak load on the grid, and for supporting off-grid power systems, due to its capabilities including tolerance for daily deep charge and discharge.

According to RedFlow, it has improved its ZBM battery to make it easier to manufacture, and more flexible to use in finished energy storage systems.

Previously, RedFlow provided ZBM units which had a number of key components, such as the pumps, that required an auxiliary AC power supply. While these components could be powered by the battery itself, this required the power to be converted from DC to AC, resulting in energy losses.

RedFlow has now replaced these AC-powered components with ones that use DC, allowing direct power from the batteries with minimal losses.

The firm claims this is the only flow battery on the market offering fully DC-based components, and this improves the economic and use case for telecommunication towers where grid supply is unavailable, as well as renewable energy plants in remote and rural sites that are off-grid.

The improvements to the ZBM also allow RedFlow to target the emerging market of DC powered microgrids, and the uninterruptible power supply (UPS) market.
