TES Systems based on 3 stages:
Thermal Storage implies Thermal Losses, so it should be any advantage to do it.
05Why Thermal Energy Storage?
#WasteHeat The Effective use of thermal energy in industry
Coupling Energy demand-availability: solar, cogeneration, free-cooling, WASTE HEAT
Taking advantage of off-peak hours (electrical tariff)
Lower nominal capacity of the equipment
Lower Energy demand
Supply assurance
Thermal inertia/Thermal protection

#WasteHeat The Effective use of thermal energy in industry
The storage of thermal energy can replace heat and cold production from fossil fuels, reduce CO2 emissions
and lower the need for costly peak power and heat production capacity.
In Europe, it has been estimated that around 1.4 million GWh per year could be saved— and 400 million tonnes
of CO2 emissions avoided—in the building and industrial sectors by more extensive use of heat and cold
storage.
Industrial waste heat recovery can be achieved by TES providing the required thermal energy demand in-
situ or at other sites by mobile TES under development.
TES is the most adequate Energy Storage technology to couple intermittent thermal energy sources to
thermal energy demand. Efficiency losses in energy transformation are avoided.
Industrial by-products and waste material may have a potential use as storage materials.
Thermal Energy Division of the Spanish Group of Energy Storage (cross-cutting Technology for Technological
Platforms) gathers research and development capacities on Storage Materials, TES System and TES integration to face
the described challenges
