Electric energy storage to heat storage heating

What is electric thermal storage (ETS)?

Electric thermal storage (ETS) devices are an effective technology for short-term storage of electric energy as thermal energy for heating applications. ETS devices can be used to shift electric demand (kW) away from peak times and thus achieve significant savings in electricity bills, reducing demand charges and benefiting from time-of-use rates.

What is thermal energy storage?

Thermal Energy Storage (TES) can store thermal energy directly and at a large capacity. The most common TES systems are direct sensible, latent heat, and thermo-chemical storages. Their energy source is either solar thermal or industrial waste heat, where the end-use of these systems is for heating, drying and cooling purposes .

What is electro-thermal energy storage (ETEs)?

As an alternative, we introduce a new modular electro-thermal energy storage (ETES) technology that is suitable for various storage needs. This storage unit can utilise various thermal storage materials (thermal oil, molten salt, and sand) at high capacities and improved efficiencies.

Can a thermal energy storage device reduce a building's electricity demand?

Under these rate structures, excessive peaks in a building’s electric demand can be expensive. To reduce these charges, thermal energy storage devices (such as an ETS) are an effective solution to partially shift the power demand and electricity consumption from peak periods to off-peak hours.

How do thermal energy storage devices work?

To reduce these charges, thermal energy storage devices (such as an ETS) are an effective solution to partially shift the power demand and electricity consumption from peak periods to off-peak hours. Charge (warm-up period): The bricks in the ETS are heated up using its electric resistive elements.

What is a man energy storage system?

Electro-thermal energy storage (MAN ETES) systems couple the electricity, heating and cooling sectors, converting electrical energy into thermal energy. This can then be used for heating or cooling, or reconverted into electricity.
