What is Supercapacitor Energy Storage System (SESS)?
SESS is similar to BESS (Battery Energy Storage Solution), which stands for Supercapacitor Energy Storage System. It refers to the technology that stores the electrical energy in the batteries or energy storage system for later use. Typically used to balance supply and demand in energy grids, support renewable energy integration, and provide backup power.
Key Features of SESS (Supercapacitor Energy Storage System) by Emtel Energy:
Supercapacitor Energy Storage System (SESS) is the advanced version of BESS (Battery Energy Storage System) that has remarkable longevity and efficiency and contributes to green energy storage with no chemical reaction taking place in the encap supercapacitor batteries. No heat is generated which is why it is ideal for large storage solutions for industrial and remote locations. Some of the other features include:
- Long Life Cycle: Emtel Energy’s BESS consist of energy storage modules that use ENCAP modules. These supercapacitor-based energy storage modules have a long lifetime of up to 500,000 cell lifecycles. Providing long-term reliability. Encap supercapacitor-based energy storage offers 500,000 life cycles surpassing lithium-ion batteries that typically offer 6,000 lifecycles.
- High efficiency: With 99.1% round trip efficiency, these systems maximize usage while minimizing energy loss during charging and discharging.
- Ecofriendly Designs: Encap’s encapsulated cell technology is made from recyclable material ensuring that the Bess solution aligns with global sustainability goals.
- Extreme Temperature Resistance: The BESS solution can operate from -30°C to 65°C, making it ideal for harsh environments.
How does BESS/SESS work?
BESS/ SESS stores excess electrical energy when generation exceeds demands and releases it when the demand surpasses generation. It uses advanced technologies like Supercapacitor-based energy storage solutions by Encap or others using lithium-ion or lead acid batteries. Supercapacitor Energy Storage Solution used by Emtel Energy is the most advanced electrostatic technology.
What are the key applications of BESS/SESS?
• Grid Stabilization: Manages the fluctuations in power supply and demand
• Renewable energy integration: Storing energy from intermittent sources like solar and wind.
• Backup Power: Providing energy during power outages.
• Peak Shaving: Reducing demand charges by supplying power during peak periods.
What are the types of batteries used in BESS/SESS?
In most of the world, usually, these chemical batteries are used:
• Lithium-ion batteries: Common due to high energy density and efficiency.
• Lead-acid batteries: Older technology, but still used in some applications.
However, we use Emtel’s supercapacitor batteries that provide fast charge and discharge rates, ideal for applications requiring high power output over short durations.
Since the world was not fully aware of the supercapacitor-based energy storage solutions by Emtel Energy, which are the advanced alternative of batteries, lithium-ion or lead acid batteries were being used. Now, Emtel Energy has deployed BESS that are being used in the remotest areas of the world to cater the energy needs.
Supercapacitor batteries by Emtel Energy have much higher energy density, and longer life cycles up to 500,000, the typical lithium-ion battery has around 6000 life cycles.
The applications of these energy storage solutions by Emtel are vast from 99.1% round trip efficiency to 100% Depth of Discharge. Many modern lithium-ion batteries are unable to achieve that because of the chemical reactions taking place in them. There is no chemical reaction taking place in the supercapacitor batteries by Emtel Energy. Emtel Energy is the proud global distributor of Enercap Power Industries LLC.
What are the challenges associated with BESS/SESS?
- Cost: Batteries, especially lithium-ion, can be expensive.
Solution of Cost: Emtel offers reasonable prices for our supercapacitor batteries. - Degradation: Battery performance declines over time, though advanced systems like supercapacitors offer longer lifespans.
Solution of Degradation: Emtel Supercapacitor batteries are not affected by degradation because of the process by which these supercaps store energy. The electrical power is stored electrostatically so no chemical reaction can lead to the degradation of the battery. - Safety: Lithium-ion batteries can overheat and catch fire under certain conditions, whereas alternatives like supercapacitors offer safer options.

Solution with Safety: Emtel Supercapacitors by Encap are very safe. There is no risk of explosion with supercapacitor batteries and no chemical reaction takes place, no degradation, and no risk of thermal runaway, Just an electrostatic battery with encapsulated cells that can run for a long time with hardly any maintenance
Case studies: Real World Applications of Emtel Energy’s BESS/SESS solutions
BESS Solutions are applicable in various fields:
Telecom Sector: Remote Tower Solutions
Before Telecom sector implementation:
- Telecom towers relied heavily on diesel generators and the grid for power.
- High operational costs were incurred due to fuel consumption and generator maintenance.
Challenges:
- Frequent power outages were common due to dependency on the grid and generator failure.
- Continuous use of diesel generators resulted in significant carbon emissions.
- Maintenance Costs: Diesel generators required regular servicing and incurred high fuel and maintenance expenses.
- Limited Sustainability: No integration of renewable energy, leading to high energy dependency on non-renewable sources.
After Telecom Sector Implementation:
Power Source:
Integrated solar energy as the primary power source with a supercapacitor-based energy storage system as a backup for power, significantly reducing dependence on diesel generators.
Positive Outcomes:
- Reduced Diesel Use: Solar energy now powers the towers during the day, leading to a drastic reduction in diesel consumption by up to 80%.
- Improved Reliability: Continuous power supply is ensured with the hybrid system even in off-grid or remote locations.
- Lower Operational Costs: With reduced diesel usage and lower maintenance requirements for the supercapacitor-based energy storage system, operational costs have been cut by nearly 60%.
- Environmental Impact: The adoption of solar energy and reduction of diesel use lowers carbon emissions by up to 70%, contributing to a more sustainable operation.
- Longer Lifespan: The supercapacitor-based energy storage system offers a lifespan of up to 500,00 life cycles, far exceeding traditional batteries.
