Technology - Enstorage

EnStorage’s flow battery chemistry utilizes HBr and H2. As power flows into the stack H2 is generated and stored. During the discharge cycle H2 is consumed and energy is generated (see below). No mechanical compressor is used in this process and only one liquid pump is in use.



The technoly has a number of advantages, including:

  • Over 10,000 cycles with minimal degradation in efficiency
  • No limitations on depth of discharge
  • Flexibility on power rating and energy rating
  • Fast response time
  • Totally self-contained – No by-products within the system or discharged outside it  
  • No emissions
  • Wide ambient temperature operating range (-20 C° to +55 C°)
  • Low internal operating temperature (40 C°- 60 C°)
  • Low O&M costs
  • Cost effective solution: $0.10 - $0.15 kW/h 20 Year LCOE
