Energy Storage Systems

Our partners manufacture a Graphene-based alternative to lithium-ion and lead acid batteries, that harnesses an electrostatic process to immensely reduce operational cost and risk for owners.

Specification ranges

Technology Differentiation

  • Solid state super capacitor with reduced area footprint 
  • Electrostatic instead of electrochemical process - 100% synthetic (non-hazardous) 
  • Non-Lithium -- safe for indoor use 
  • Non-flammable with no thermal runaway or heat signature  

  

Performance

  • +500,000 cell cycles 
  • 4 cycles daily at 100% depth of charge 
  • Clean load leveling power via voltage and frequency regulation 
  • Transfer 100% of stored energy in nanoseconds
  • Simultaneous discharge / recharge 
  • Degradation <1% - no need to oversize 
  • Less than 1% leakage in static storage phase 

Energy Density & Durability

  • 350Wh/Kg energy density (800Wh/Kg expected late 2025) 
  • Footprint reduction compared to traditional BESS  


  

Maintenance & Longevity

  • Minimal maintenance required – modules rated for lifetime 
  • Single modules can be replaced during operation  
  • Warranty up to 20 years compliance & manufacturing   


Durability & Environmental Resilience Maintains 

  • Operating range: -22°F to +140°F (-30°C to +60°C)  
  • Does not combust when in contact with salt or fresh water  

Electrostatic long duration energy storage (ELDES) Differentiators

 Electrostatic Long Duration Energy Storage provides extended asset life, reduces operational risk, and delivers best in class operations for critical back up power or long duration energy. Ask us about current availability from domestic suppliers.
