As global energy demands accelerate and industries seek cleaner, safer, and longer-lasting storage solutions, one technology is rising quietly but powerfully above the rest — electrostatic energy storage. At the forefront of this breakthrough is Emtel Energy, delivering a game-changing solid-state solution that’s reshaping the future of long-duration storage.
Introducing ELDES: The First True Electrostatic Long Duration Energy Storage
Emtel’s proprietary technology, Electrostatic Long Duration Energy Storage (ELDES), uses solid-state, encapsulated supercapacitors to deliver reliable, safe, and sustainable energy — without the risks and limitations of chemical batteries like lithium-ion. Unlike traditional batteries that depend on electrochemical reactions, Emtel’s system stores energy in electric fields, which means:
- No thermal runaway or fire risk
- No degradation over time
- No hazardous materials or mining
- 100% recyclable and 80% biodegradable
This makes Emtel’s ENCAP and ENPACK systems the safest and most sustainable energy storage solution available today.
Why Electrostatic Beats Lithium: A Head-to-Head Advantage

Energy Density | Up to 350 Wh/kg ✅ | 150–250 Wh/kg ❌ |
Built for Every Application
Emtel’s energy storage systems are designed to adapt — from kWh to multi-MWh scale — offering superior flexibility and performance across industries:
- Telecom Backup: Compact ENCAP modules deployed in remote sites with zero maintenance.
- Data Centers: Instant failover UPS systems with zero degradation and hot-swap capability.
- Off-Grid Microgrids: Fully containerized ENPACK systems with fast charge/discharge support.
- Grid-Scale Deployments: 2MWh to 10MWh+ systems ready for load leveling, peak shaving, and frequency regulation.
- EV Charging: Enable ultra-fast DC charging with no grid reinforcement needed.
Safety Proven in Real-World Conditions
From the deserts of Abu Dhabi to the alpine chill of the European Alps, EMTEL systems have been tested under extreme environments:
- +140°F operation without air conditioning
- -22°F cold-weather deployments without heating
- Fire-tested and self-protecting containers
- Up to four full charge/discharge cycles per day with zero degradation
No lithium-ion system can match this level of reliability, resilience, and safety.
Lowest LCOS in the Industry
Emtel’s system provides the lowest Levelized Cost of Storage (LCOS) thanks to:
- No degradation over life — maintain full capacity for 20+ years
- 100% usable energy at all times
- High C-rates without lifecycle penalty
- Zero cooling requirements, reducing OPEX
This translates to up to 40% more energy throughput compared to lithium-based systems.
Built for the Circular Economy
Sustainability isn’t a feature — it’s a foundation. EMTEL systems:
- Use graphene-based, non-toxic, fully recyclable materials
- Require no lithium, cobalt, or hazardous mining
- Are built using globally sourced components (non-China dependent)
- Are hot-swappable, reducing electronic waste and system downtime
Final Word: The Safer, Smarter, Stronger Future
The energy storage market is changing — and Emtel Energy is leading that change. With unmatched cycle life, superior safety, rapid deployment capabilities, and a low-cost profile, EMTEL’s solid-state electrostatic technology is not just a better battery alternative — it’s an entirely new category.
It’s time to stop compromising between safety, performance, and sustainability.
It’s time to go electrostatic.
