Frequently Asked Questions
Technology & Performance
1. What makes Emtel’s energy storage technology different from lithium-ion batteries?
Emtel’s supercapacitor-based technology offers high energy density, rapid charging, and long-duration storage without degradation. Unlike lithium-ion batteries, our systems do not rely on chemical reactions, making them safer, more efficient, and highly durable.
2. How long can Emtel’s energy storage solutions hold a charge without loss?
Our energy storage systems can hold a charge for months. We’ve shipped fully charged containers overseas for 50+ days, arriving with 99% of their charge intact.
3. What are the benefits of using graphene in energy storage?
Graphene enhances the performance of our modules by increasing energy density, improving charge retention, and extending product lifespan. It also enables faster energy transfer and contributes to the overall sustainability of our systems.
Manufacturing & Availability
4. Where are Emtel’s energy storage systems manufactured?
Currently, Emtel’s ESS are manufactured in the UAE with the exception of the EMWALL, which is now being manufactured in the USA.
5. Are Emtel’s products eligible for government incentives or rebates?
Yes, Emtel’s energy storage systems may qualify for various government incentives. These details can be worked through our resale partners, who can guide you through available programs in your region.
Applications & Use Cases
6. How does Emtel’s technology support data center energy needs?
Emtel’s long-duration energy storage solutions help data centers reduce dependence on traditional backup power sources (using our high-capacity ENPACK), and ensuring uninterrupted operations while lowering energy costs and carbon emissions (our rack-based backup system ENRACK). Our high-density storage systems provide reliable, sustainable backup power without the fire risks associated with lithium-ion batteries, and do not require supplemental cooling.
7. How does Emtel’s technology help with grid stability and renewable integration?
Our energy storage solutions allow utilities and businesses to store excess renewable energy and release it when needed, reducing grid congestion and improving stability. By providing long-duration storage without energy loss, Emtel enables greater reliance on wind, solar and other alternative energy sources.
Sustainability & Safety
8. How is Emtel’s energy storage more sustainable than traditional lithium-based options?
Unlike lithium-ion batteries, Emtel’s supercapacitor-based storage does not rely on scarce minerals like cobalt and nickel, reducing environmental impact. Our systems are carbon-neutral and longer-lasting, fully recyclable, and pose no risk of thermal runaway.
9. Are Emtel’s energy storage systems safe? Do they pose fire risks?
Yes, our systems are inherently safe. Unlike lithium-ion batteries, Emtel’s supercapacitor-based technology does not use volatile chemicals, eliminating the risk of thermal runaway or fire hazards.
10. What is the expected lifespan of an Emtel energy storage system?
Emtel’s storage systems are designed for long-term performance, lasting significantly longer than lithium-ion batteries. With nearly no degradation curve, even over 500,000 cell lifecycles, we offer a reliable and cost-effective energy storage solution.
Additional FAQs
11. How much noise do your systems make?
Our systems are whisper-quiet. Our systems operate between <30 dBA and <60 dBA, depending on the product, making them quieter than traditional energy storage solutions. A normal conversation is about 60dBA.
12. How can I get your products?
We work through our established resale partners to provide the best sales, installation, and maintenance experience. Please contact us to find out which reseller is in your area.
13. How does Emtel price its energy storage systems?
Our pricing is extremely competitive due to the longevity and resilience of our systems. Unlike lithium-ion storage, our technology allows for 100% depth of discharge, meaning there’s no need to oversize systems. Additionally, maintenance is minimal, and no cooling is required, leading to an extremely low Levelized Cost of Storage (LCOS) over the system’s lifetime. We have reduced space requirements than other solutions, saving per square foot or acre.
While our upfront CAPEX may be higher than lithium-ion, we are not focused on undercutting lithium’s rapidly dropping prices. Instead, we offer a long-term solution with minimal maintenance, superior efficiency and durability over 500,000 cycles.
