How are heat and cold stored in a PHES system?

Thermal stores Heat and cold are stored in thermally insulated, isobaric steel containments. Both HS and CS of the present PHES system are ‘packed-bed’ type storages. Packed-beds are loosely packed with a particulate storage material normally spherical in shape to allow for working fluid flow for effective heat transfer.

How much power can a PHES system store?

The facility is intended to demonstrate operation, verify system control strategies, and validate data. While the SwRI pilot is laboratory-scale, a full-size Malta PHES system will be able to store more than 100 MW of power for eight hours to eight days or longer (1,000+ MWh). One such system is being developed in partnership with Siemens.
