FAQ’s

Thermal Energy Storage (TES) is a technology that stores energy in the form of heat, which can be released when needed. It enables decoupling of energy supply from demand, providing flexibility, efficiency, and cost savings. Thermal Energy Storage stores thermal energy up to 600°C, making it suitable for industrial heat applications, district heating, and integration with renewable energy.

TES bridges the gap between intermittent renewable energy generation (solar, wind) and constant industrial demand. It helps reduce reliance on fossil fuels, lowers CO₂ emissions, and provides 24/7 clean heat to industrial processes. TES enables industries to replace fossil-fuel boilers with clean electricity and thermal energy, accelerating decarbonization.

EnergyIntel’s TES operates efficiently up to 600°C, covering the low- to medium-temperature heat market, which represents over 50% of industrial heat demand globally.

Yes. EnergyIntel’s TES technology provides continuous thermal output that can fully or partially substitute fossil-fuel boilers. This reduces operational costs, stabilizes energy prices, and cuts CO₂ emissions significantly.
  • TES stores heat, not electricity.
  • Unlike lithium-ion batteries, TES does not degrade over cycles.
  • TES is safer, cost-effective, and better suited for industrial heat demand.
  • EnergyIntel’s TES solution offers lower levelized cost of storage (LCOS) than electrochemical batteries for thermal applications.

Each unit stores 0.55 MWh (thermal). Units can be installed in clusters to reach multi-MWh or even GWh levels, depending on customer demand.

The system is designed for daily and multi-day storage. Depending on configuration and insulation, heat can be retained for 24–48 hours with minimal losses.

Absolutely. EnergyIntel’s TES solution is ideal for coupling with solar PV, wind farms, or grid electricity. It absorbs excess renewable electricity and delivers dispatchable clean heat when required, stabilizing the grid and supporting renewable integration.

Yes. our Thermal Energy Storage uses non-toxic, durable thermal storage materials and has no risk of fire or explosion (unlike chemical batteries).

  • Eliminates fossil fuels in industrial heat.
  • Zero direct CO₂ emissions.
  • Recyclable materials.
  • Enables higher penetration of renewable energy.

From a single module to multi-MW plants, our TES grows with your business needs. Multiple units can be installed for district heating, industrial parks, or grid-scale applications.

3.65*2.67*2.81 m  Or simpler, 2 TES units can fit perfectly in a 20 ft container.
