Swansea University, a research-led British university, has purchased Redflow’s unique ZBM2 zinc-bromine flow battery technology as the energy storage backbone for its Active Building demonstrator -– an award-winning classroom that generates, stores and releases solar energy at the point of use.
The microgrid is built around 120 kWh of Redflow batteries and is supplied with building-integrated, thin-film photovoltaic solar panels, as well as a solar wall that supplies the warm air to a heat-pump for space and water heating. Since being built, the classroom has proven the Active Buildings concept by generating more energy than it has used over an annual cycle, and during high solar summer months, the system will return power to the local electricity grid.
Redflow’s small 10 kWh flow battery units are the only commercially available flow battery energy storage system that allowed accurate sizing for the 120 kWh system. Additionally, the Redflow battery operates “out of the box” with the Victron inverters and controllers that provide the power conversion for the Swansea University minigrid.

Redflow CEO & Managing Director Tim Harris said “Redflow is delighted that Swansea University selected our technology. This project with its dual renewable generation sources will be a bench-mark for flow-battery minigrids. This is an emerging segment that Redflow is focussed upon, having recently deployed some PV-only minigrids in the agricultural sector in Australia.”
