It is interesting how major new directions in the energy sector take time to mature. Fluence Energy (NASDAQ:FLNC) is a case in point. Formed in 2018 as a JV between Siemens Aktiengesellschaft (OTCPK:SIEGY) and The AES Corporation (AES), each of the participating companies have been involved in opening up energy storage and management for a number of years. Fluence means more focus than having these programs within bigger company structures. Fluence has stayed out of the limelight as it establishes its business and begins to become a significant company in energy storage and management of renewable energy.
