Store Energy
Without Risk.
Our nano-augmented supercapacitor technology delivers the safety, cycle life and operating range that commercial and industrial operators actually need — without the compromises of lithium-ion.
Lithium-Ion Carries Risks You Shouldn't Have to Accept.
Thermal runaway. Fire. Temperature sensitivity. A cycle life that degrades faster than most operators plan for. Supply chains built on cobalt and lithium mined under conditions that create serious ESG exposure.
There is a better option available today.
Graphene Nanotube Composites. Solid-State. Fully Electric.
247 supercapacitor modules contain no rare or expensive metals and require no polluting production processes. The result is an energy storage module with battery-like characteristics but performance that exceeds any conventional battery on almost every relevant dimension.
Products are available in rack-mounted configurations and containerised units. ATEX-certified configurations are available for hazardous environments. Products can be installed in existing buildings without modification to fire suppression or structural requirements.
87% Overall Score. Li-Ion Scores 58%.
On our independent multi-dimensional benchmark covering energy density, charging speed, power density, operating temperature, charge retention, safety, price per kWh, price per kW, and recyclability — the 247 supercapacitor leads every alternative on the market.
No thermal runaway. No rare metals. No compromise on longevity. Available now.

From shopping street to production floor
the same supercapacitor core.
247 Energy serves both commercial and industrial environments from a single modular architecture. The use case determines the configuration — not a different product.
The 247 Energy supercapacitor system is engineered from the ground up for commercial environments — offices, hospitals, retail centres, hotels and logistics hubs where safety, aesthetics and operational continuity are non-negotiable. Unlike lithium battery systems, it installs inside any building without special fire suppression or structural reinforcement.
For ports, manufacturing plants, data infrastructure and heavy industry, 247 Energy delivers the high-power performance that lithium chemistry cannot match. Fast charge, fast discharge, cycle continuously — with an intelligent energy management layer that makes every kilowatt work harder.
Zero risk of thermal runaway. No flammable electrolytes. No toxic off-gassing. Compliant with indoor installation requirements without additional fire suppression systems.
Modular architecture scales from 15 kWh to multiple MWh. Configured to match your exact load profile, footprint and peak demand requirements.
Active cooling systems in lithium installations generate significant acoustic output. 247 Energy storage operates at 55 dB(A) — quiet enough for open-plan offices and patient areas.
Supercapacitors experience negligible calendar ageing. 247 Energy storage is designed for a 15-year operational life with no scheduled cell replacement.
Less than 10% capacity loss over the system lifetime. The energy you contract for is the energy you get — every day for the life of the system.
Supercapacitor systems have inherently low standby losses. 247 Energy storage draws minimal power when not actively cycling — critical for facilities where parasitic consumption directly impacts operating costs.
Accept charge at up to 10 times the capacity per hour. Captures regenerative braking energy from cranes and conveyor systems that lithium batteries cannot absorb fast enough.
Containerised outdoor configurations and indoor rack formats available. Deployable adjacent to high-voltage switchgear, in temperature-controlled plant rooms, or in open-air industrial environments.
The 247 ERP platform monitors, dispatches and optimises energy flows across all connected assets in real time — peak shaving, demand response, grid balancing and predictive load management from one interface.
Network-segmented architecture separates operational technology from IT systems. Encrypted remote communication, role-based access control, and IEC 62443 documentation available for NIS2-regulated facilities.
Proven results. Real deployments.

Common Questions.
- What is the cycle life of 247 Energy supercapacitor modules?
- The projected cycle life exceeds 15.000 cycles at 25°C, with a certified product lifetime of 10 years — significantly longer than conventional lithium-ion or LFP batteries.
- Are 247 Energy supercapacitors safe for indoor installation?
- Yes. The solid-state, non-chemical cell chemistry produces zero risk of thermal runaway. Products can be installed in existing buildings without modification to fire suppression or structural requirements.
- What temperature range do 247 supercapacitor modules operate in?
- The modules operate from −20°C to +50°C without active cooling systems, making them suitable for outdoor installations and thermally challenging industrial environments.
- Do 247 supercapacitor batteries contain cobalt or lithium?
- No. The graphene nanotube composite cell chemistry contains no rare or expensive metals, including no cobalt and no lithium, eliminating supply chain ESG risks associated with conventional battery chemistries.
