Flowgroup, a UK energy technology developer, has received an order for two compressed air batteries totaling 150kW capacity from Trane Canada for a telecoms company.
Flowgroup’s air battery business, ambiguously named Flow Battery, will supply one 100kW and one 50kW compressed air battery units for a telephone exchange in Toronto which is part of a national network.
The compressed air battery was selected for resistance to a range of temperatures. While the larger unit will be housed inside, the smaller battery will be outside where it will be exposed to temperatures between -40°C to 40°C.
The compressed air battery can produce power on demand using a store of ordinary compressed air from cylinders to drive a scroll generator, which can spin up and decelerate rapidly to match output to load.
Flow Battery has an agreement with UK national grid to supply 200 compressed air batteries per year to replace existing lead-acid back up batteries at substations across England and Wales.
