Supercap based solution with no chemical storage media so does not have any of the limitations of chemical storage
-
Cycle life, efficiency, temperature resilience and charge / discharge
flexibility significantly (order of magnitude) better than chemical batteries -
Similar footprint to chemical batteries
-
Economically viable
The Technical Limitations of Chemical Batteries
Problem...
Chemical batteries have technical limitations, all revolving around:
-
Rate of charge
-
Rate of discharge
-
Ambient temperature
-
Depth of discharge
-
DC to DC round trip efficiency
-
All of which affect roundtrip DC to AC efficiency, capacity, cycle life and therefore cost
-
Making deployment challenging and therefore limiting the ability to use storage effectively to improve capacity, integrate renewables, add resilience and reliability
Solution...
WEST Energy Storage
WEST’s patent pending storage solution, Sirius, based on supercapacitor storage media, does not have any of the technical challenges of chemical batteries
