As part of global smart city development, a new milestone has been reached: the successful deployment of a containerized, off-grid EV charging system powered by supercapacitor-based energy storage. Developed by Emtel Energy, this breakthrough supports clean mobility ambitions while aligning with global sustainability frameworks, including the United Nations Green Power Strategy and the Sustainable Development Goals (SDGs).
Sustainable Energy for the Smart Cities of Tomorrow
As electric mobility expands, so does the need for reliable, scalable, and clean infrastructure. But powering remote EV charging stations without access to grid electricity remains a global challenge.
That’s where Emtel Energy’s ENCAP solution comes in — a solar-integrated, supercapacitor-based energy storage system, installed in the desert and delivering clean power with zero emissions.
By eliminating diesel generators and chemical-based battery risks, this project also contributes directly to carbon footprint reduction.
What Powers This EV Charging Solution?
Here’s what makes the system both powerful and sustainable:
• 345 kWh of supercapacitor storage
• 540 V DC bus
• 80 kW solar PV system
• 216 kW Enserver output
• Load capacity: 20 kW to 180 kW peak
• Mode: 100% off-grid, containerized
This modular energy platform acts as a renewable microgrid, delivering power where traditional infrastructure falls short — enabling sustainable transport in some of the most extreme environments on Earth.
Live Dashboard. Real Impact.
ENCAP features a real-time monitoring dashboard that tracks system performance and energy efficiency.
• Battery Power (Blue): Adaptive charge/discharge synced with solar availability and EV load
• PV Power (Green): Stable generation from sunrise to early afternoon
• Load Power (Orange): High fluctuations handled smoothly up to 180 kW
• Grid Power (Gray): Zero — demonstrating complete grid independence.
Key metrics from daily operation:
• State of Charge: 98.9%
• Voltage: 534.8 V
• Temperature: 19.2°C
• Charge Energy: 32.4 kWh/day
• Discharge Energy: 30.8 kWh/day
These figures reflect optimized solar harvesting and efficient system cycling — keeping EV charging reliable and emissions-free.
Why Supercapacitors Are the Smarter Choice
ENCAP’s use of supercapacitors over conventional lithium or lead-acid batteries offers real sustainability and performance advantages:
• Instant charge/discharge response
• No thermal runaway risk
• Extended cycle life with minimal degradation
• High efficiency even in extreme temperatures
In the context of EV infrastructure, supercapacitors deliver the responsiveness and durability required for on-demand, fast charging — while maintaining a small environmental footprint.
Plug-and-Play. Scalable. Desert-Proven.
ENCAP is housed in a rugged, modular container, purpose-built for remote installations. It’s engineered for plug-and-play deployment, minimizing logistics and maintenance. And as demand grows, multiple containers can be scaled side-by-side — powering more chargers or even entire remote facilities.
This flexible architecture supports the UN’s Green Power principles by enabling:
• Decentralized renewable power
• Carbon-neutral mobility
• Infrastructure without fossil fuel dependency
A Major Step Toward Global Climate Goals
By powering off-grid EV charging with solar and supercapacitors, Emtel Energy is actively reducing carbon emissions and redefining how cities approach clean infrastructure.
This project isn’t just about providing remote energy — it’s about meeting climate action targets, enabling green mobility, and creating replicable models for sustainable infrastructure across emerging regions.
ENCAP shows that clean energy at scale doesn’t have to wait. It’s ready now — deployed, running, and redefining what’s possible.
