• At AC2DC Storage, we lead the way in offering scalable solid-state energy storage solutions with ELDES, available from 10kW to multi-megawatt systems.
  • Our systems are safe, non-explosive, non-toxic, and non-flammable, which lowers insurance costs and removes the need for cooling systems.
  • They are also fully sustainable, lasting up to 35 years and are 100% recyclable and upcyclable.
  • We provide excellent performance in temperature tolerance and output.
  • At AC2DC Storage, we focus on creating safer, smarter, and longer-lasting energy systems. Our latest innovation, ELDES, is an electrostatic storage platform that surpasses lithium in safety, durability, and sustainability.

Electrostatic Long Duration Energy Storage — Reinventing What's Possible

 

What is ELDES?

ELDES technology stores energy electrostatically rather than chemically, using a solid-state, man-made graphene architecture that eliminates thermal runaway, reduces environmental risk, and lasts for millions of cycles.

 

Why Electrostatic Energy Storage?

Safety

  • No fire risk, no thermal runaway, no toxic discharge. ELDES is inherently stable and safe to deploy anywhere.
 

 

Speed

  • Charge and discharge in seconds. ELDES handles rapid energy needs with near-zero latency.
 

 

Durability

  • Designed to last over 1 million charge cycles—20x more than lithium-ion batteries.
 

 

Sustainability

  • No rare earth metals, no degradation, 100% recyclable. Clean energy needs clean storage.

 

 

Explore the Possibilities

ELDES is powering a new generation of microgrids, EV charging infrastructure, commercial backup systems, and more.

Our clients demand reliability, safety, and innovation. ELDES delivers.
