In addition to the intrinsic advantages related to HBr electricity storage, Elestor has developed a unique HBr storage system concept (patent pending), whereby the full focus has been on minimizing the cost per stored kWh.
Each individual system quality (lifetime, no. of (dis)charge cycles, efficiency/cycle, material costs, production costs) contributes to the total cost per stored kWh. In this number, also known as the ‘Levelized Cost of Storage’ [€/kWh], every system quality is taken into account.
Minimizing the costs per stored kWh
By minimizing manufacturing cost and at the same time optimizing the performance of each system quality, Elestor managed to reduce the total costs per stored kWh. To accomplish this milestone, Elestor has introduced several new technical developments, resulting in:
Long system lifetime
» Over 10.000 charge/discharge cycles
High system efficiency
» 80% per complete charge/discharge cycle
Low material costs
» Abundant availability of Br2 and H2
Low production costs
» No H2 compressor required
» Smart production procedures
» Innovative and simplified – yet robust -
Storage system versus battery pack
The Elestor storage solution is to be considered a machine rather than a closed battery pack: All parts, circulation pump, valves, electrochemical cells and control electronics, are easily accessible. In contrary to closed battery packs, Elestor’s storage systems can always be repaired, serviced and upgraded, which further prolongs the systems’ already long lifetime, leads to a further reduction of storage costs per kWh, and further enhances the return on investment.
