Of the large-scale storage technologies (>100 MWh), Pumped Heat Energy Storage (PHES) is emerging now as a strong candidate. Electrical energy is stored across two storage reservoirs in the form of thermal energy by the use of a heat pump. The stored energy is converted back to electrical energy using a heat engine.
Heat pumps are used to transfer heat because less high-grade energy is required than is released as heat. Most of the energy for heating comes from the external environment, only a fraction of which comes from electricity (or some other high-grade energy source required to run a compressor).
Heat pumps use a refrigerant as an intermediate fluid to absorb heat where it vaporizes, in the evaporator, and then to release heat where the refrigerant condenses, in the condenser. The refrigerant flows through insulated pipes between the evaporator and the condenser, allowing for efficient thermal energy transfer at relatively long distances.
Integrating heat pumps with high-efficiency latent heat thermal energy storage systems with phase change materials (PCMs) can increase the heat temperature and heat quantity, enabling flexible heat regulation and cascade utilization.
Thermal stores The nominal charge/discharge duration of the stores is 4.0 hrs at full-load. Although the heat pump/engine was operated for sufficient length of time to establish equilibrium conditions and adjust correct valve timings of the heat pump/engine, the thermal stores were not charged completely.
Electricity rates will also influence the attractiveness of heat pumps. In cooling mode, a heat pump’s operating performance is described in the US as its energy efficiency ratio (EER) or seasonal energy efficiency ratio (SEER), and both measures have units of BTU/ (h·W) (1 BTU/ (h·W) = 0.293 W/W). A larger EER number indicates better performance.
