French startup EPYR develops thermal energy storage systems that convert surplus renewable electricity into high-temperature heat. Its technology captures low-cost renewable electricity, stores it as heat, and provides high-temperature energy when needed.
Further, the stored energy is retained in specialized bricks with minimal thermal loss and later delivered on demand to industrial facilities through a containerized system. This technology offers zero-emission operation, cost parity with fossil fuels, and plug-and-play installation to decarbonize heat production.
Emtel Energy USA offers a Graphene-Based Electrostatic Storage
USA-based startup Emtel Energy USA develops an electrostatic long-duration energy storage (ELDES) system that offers an alternative to lithium-based batteries. Its solid-state supercapacitor technology stores electricity electrostatically to provide high power density and long cycle life.
The startup’s container, ENPACK, features graphene-based supercapacitor units for applications including electric vehicle (EV) charging, microgrids, and off-grid backup systems.
Further, the integrated ENSERVER control unit manages performance, monitors system health in real-time, and allocates power across connected loads. The containers enable peak shaving, grid offset, and resilient microgrid operations for long-duration energy storage.
Eleven Energy makes a Sodium Battery System
UK-based startup Eleven Energy develops sodium battery systems to store power from solar panels. The core battery pack offers 4.5 kWh of storage, expandable to over 33 kWh to power in extreme temperatures ranging from -20°C to 55°C.
The systems include a 6 kW hybrid inverter and an energy management system to schedule charging based on electricity tariffs and solar forecasts. Also, they control connected devices like EV chargers and heat pumps and support real-time data access with remote configuration. These systems reduce costs while supporting the clean energy transition.
FPR Energy builds a Concentrated Solar Thermal (CST) Technology
Australian startup FPR Energy builds a particle-based concentrated solar thermal technology to offer zero-emission, continuous heat and power for industrial applications. The technology uses heliostats to focus sunlight onto a central receiver, where inert ceramic particles absorb heat at temperatures proven at 850°C and scalable up to 1200°C.
These heated particles are stored in insulated silos and later transferred through heat exchangers to supply on-demand thermal energy for industrial processes or to generate electricity via steam turbines.
Next, the particles are then cooled and recirculated to enable a closed-loop energy cycle with minimal losses. Thus, the technology supports bulk energy storage, simplifies materials handling, and eliminates reliance on hazardous substances.
FeX Energy offers an Iron-based Energy Storage
Canadian startup FeX Energy provides iron-based energy storage systems powered by a proprietary iron arc reactor. This reactor stores surplus electricity by heating iron. Then, it releases that stored energy as high-temperature heat.
The iron system undergoes a natural and controlled reaction with air due to its non-toxic, non-volatile, and corrosion-free properties. With a modular design, the system meets industrial and grid-level thermal demands.
