At February’s Intersolar Convention, the Center for Community Energy discovered one of the most exciting innovations in energy storage to date: Emtel Energy USA’s graphene-based supercapacitor-based LDES. This isn’t just another battery: this is a whole new category. With lightning-fast charging, radical safety advantages, and no reliance on rare earth minerals, Emtel’s technology could completely reshape how we think about powering our homes, businesses, and communities.
A Glimpse into the Future of Energy Storage
When we caught up with Phillip Martin Jr from Emtel Energy USA, the conversation was nothing short of electrifying. Fresh off winning a New Product award at Intersolar, Phillip Martin Jr shared the company’s mission to reinvent the way we store energy, without the environmental baggage of lithium-ion batteries.
At the heart of this system, developed in the UAE by inventor/manufacturer Enercap Technologies, is synthetic hybrid graphene, a material synthetically engineered without any mined minerals or hazardous chemicals. Not only is it 100% recyclable and 80% biodegradable, but it also sidesteps the environmental and geopolitical concerns tied to traditional battery supply chains.
As a global distributor for Enercap, Emtel Energy USA is playing a key role in delivering this technology to meet the immense need in the US market and beyond.
Built for Resilience: From the Inside Out
Unlike conventional batteries, Emtel’s graphene energy storage, often referred to as Electrostatic Long Duration Energy Storage (or ELDES) isn’t based on chemical reactions. That means it can charge/discharge extremely quickly, provide deep cycles to safely discharge 100% of its stored energy, and last 30+ years with almost no degradation. There’s no thermal runaway, no fire risk, and no toxic off-gassing. Even under extreme conditions, including a literal fire, these units do not present an explosive risk like chemical batteries.
While serving the same purpose as a battery, this new technology is far more advanced. It’s a revolution in how we store and use power.
Small Company, Big Impact
Though newly-formed in 2024, Emtel Energy USA is punching well above its weight. Set up as a partner company to the UAE-based Emtel Energy (est. 2006),Emtel benefits from Enercap Technologies 16GWh manufacturing hubs in Dubai and Abu Dhabi they’re moving quickly to challenge industry norms. Emtel has also begun manufacturing the U.S.- delivering the EMWALL, a residential and C&I Powerwall-challenger and the first product launched under the Emtel brand.
Emtel’s flagship solution is the ENCAP module which is integrated into larger storage architecture such as the “ENRACK” (designed for data centers) and“ENPACK” (Utility-scale), all of which are able to cycle 4x per day and last for over 500,000 cell cycles. Each unit is designed with modularity in mind, making them easy to maintain and eventually upgrade as the technology evolves. The company is working toward UL certifications, which are expected by the third quarter of 2025.
Their products are already being tested in microgrids and data centers, including a 600kWh ENPACK test through Duke Energy, commissioning in Q4 2025. Residential applications are also a major focus as the EMWALL launches, especially in markets like San Diego, where electricity rates are the highest in the continental United States and residents are seeking clean, safe, and affordable backup power. Modular, upgradable, and competitively priced, these units offer a real alternative for homeowners.
- Compatible with hybrid inverters like Sol-Ark
- Designed for full discharge and rapid cycling
- Charge and discharge simultaneously
- Automatic transfer between grid, genset and storage
Clean Energy, No Compromises
From its ethical materials to its extreme safety profile, Emtel’s technology checks every box for what a next-generation storage solution should be. There’s no mining, no fires, no toxic waste; just clean, rapid, and resilient energy.
What’s Next?
At the Center for Community Energy, we’re thrilled to witness the rise of technologies like Emtel’s, which could play a vital role in building a decentralized, resilient grid. With time-of-use rates and blackout risks on the rise, the demand for safe, long-lasting energy storage has never been greater.
Graphene supercapacitor-based tech could be the breakthrough the clean energy transition has been waiting for. We’ll be keeping a close eye on Emtel Energy USA and cheering them on every step of the way.
