  • 5,384,489 describes a wind powered electricity generating system including wind energy storage whereby wind energy is used to heat a heat transfer fluid. After being heated, the heated fluid is added to an insulated storage tank. The heated thermal fluid is used to generate electricity during periods of low wind speed and or high electricity demand.
  • the heated thermal fluid is introduced to a heat exchanger and is used to create steam in a vapourizer chamber.
  • the steam is then directed to a steam powered electricity generator.
  • the thermal dynamic conversion efficiency of the storage and recovery system described in the Bellac Patent is said to be low.
  • Various fluids are suggested as the heat transfer fluid, including water.
  • the storage tank is not pressurized and the heat transfer fluid is in liquid form as the heat transfer fluid is stated to be at atmospheric pressure.
  • a heat storage medium for, use with a fluid in storing and supplying heat energy produced by electricity comprises a three dimensional structure.
  • the three dimensional structure contains electric heaters embedded in the structure.
  • the heaters are connected to a source of electricity to provide heat energy to the storage medium.
  • the heat storage medium contains a plurality of passages connected to permit the fluid to flow through the passages to remove heat energy from the heat storage medium.
  • a heat storage medium for use with a fluid is used to store and supply heat energy.
  • the heat storage medium comprises a heat storage area having a solid heat transfer medium therein, with passages extending through the heat storage medium.
  • the passages are connected to permit the fluid to flow through the heat storage medium to charge or discharge the heat storage medium based on the temperature of said fluid relative to the temperature of said heat transfer medium.
  • a method of storing heat energy in a heat storage medium comprises embedding electric heaters in said heat storage medium, connecting the heaters to a supply of electricity to provide heat energy to the heat storage medium and activating or deactivating said heaters as required, storing the heat energy in the heat storage medium, the heat storage medium containing a plurality of passages to receive a fluid and causing the fluid to flow through the passages to remove heat energy from the heat storage medium.
  • Figure 1 is a schematic perspective view of a thermal storage medium
  • Figure 2 is a schematic perspective view of a further embodiment of a heat storage medium
  • Figure 3 is a schematic perspective view of a further embodiment of part of a heat storage area.
  • a heat storage medium being a high temperature heat reservoir 10 having a plurality of electric heaters 12 located therein in a solid heat storage area 14.
  • Channels 16 having a fluid inlet 18 and a fluid outlet 20 extend through the reservoir 10.
  • the heaters are connected by electrical lines 22 to a source of electricity (not shown).
  • the channels receive fluid that is preferably steam or a combination of steam and water. As the fluid passes through the reservoir, it picks up heat from the heat storage area 14 and exits through the outlet as saturated or superheated steam. The steam is then used, for example, to power turbines (not shown) to produce electricity during peak power periods.
  • the high temperature heat reservoir 10 is being charged or heated, no fluid will be flowing through the channels 16.
  • the solid heat storage medium can be heated to higher temperatures exceeding 100 0 C and preferably to temperatures in the range of 200 0 C to 900 0 C.
  • heat will flow from the heat storage area to the fluid as the heat storage medium discharges.
  • the electric heaters will not be operating.
  • the electric heaters will be operating and there will be preferably no fluid flowing through the channels.
  • the flow of fluid through the channels is controlled by a controller (not shown).
  • the heat storage area is hot enough to vaporize the fluid and preferably the fluid is water/steam that becomes saturated or superheated between the inlet and. the outlet of the heat storage medium.
  • the electric heaters are interspersed throughout the heat storage area.
  • the heat storage medium has insulation on an outer surface thereof, but the insulation has been omitted from the drawings as it is conventional.
  • the heat storage medium is sized and operated at a sufficiently high temperature to convert any water at the inlet into steam at the outlet and, preferably, water, wet or saturated steam enters the inlet and superheated steam exits from the outlet.
  • the solid heat storage area can be constructed of various suitable materials including steel, iron, copper, rocks, soapstone, lava rock, firebrick, alumina brick, magnesia brick, clay brick, brick, manufactured brick, ceramics or other solid material or particulate matter.
  • the electric heaters are preferably electrical resistance heaters but induction heaters, microwaves or other sources of heat from electricity can be used.
  • bricks that are used to store heat in the heat storage area can be designed to be electric heaters.
  • the solid medium can include broken pieces and is chosen to withstand a broad range of temperature change without a phase change and can withstand repeated changes in temperature without breaking down.
  • the material of the solid heat storage area must be able to receive and store heat energy.
  • the channels can be arranged in a continuous serpentine or straight path inside the heat storage area. Instead of one channel extending through the heat storage medium, several channels can be used. Insulation is applied to maintain the heat within the heat storage medium for as long as reasonably possible. While other heat transfer fluids can be used, water or substantially water is preferred.- Additives can be added to the water to maintain the water at a sufficient quality.
  • a solid heat storage medium that is a low temperature heat reservoir 24.
  • the low temperature heat reservoir 24 differs from the high temperature heat reservoir 10 as the low temperature heat reservoir 24 does not contain any electric heaters and has a greater number of channels 26 and therefore a greater heat transfer area.
  • a solid heat storage area 28 of the low temperature heat reservoir 24 is heated by steam that passes through the channels 26 and thereby heats up the heat storage area 28.
  • the low temperature heat reservoir 24 has a fluid inlet 30 and a fluid outlet 32.
  • the heat reservoirs 10, 24 are preferably charged during low peak power periods and discharged during high peak power periods. During high peak power periods, the electric heaters of the heat reservoir 10 are preferably no longer receiving electricity and are therefore shut off.
  • the steam entering the fluid inlet 30 of the low temperature heat reservoir 24 during high peak power periods preferably has a lower temperature than the temperature of the heat storage area and increases in temperature between the inlet 30 and the outlet 32.
  • the preheated steam then passes from the outlet 32 to the inlet 18 of the high temperature heat reservoir 10.
  • the preheated steam passes through the channels 16, the steam becomes superheated.
  • the thermal storage medium 24 has more channels extending through the heat storage area than the thermal storage medium 10 does as the thermal storage medium 24 can be used to receive heat energy from or supply heat energy to the solid heat storage area depending on the temperature of the fluid relative to the temperature of the heat storage area.
  • FIG 3 there is shown part of the heat storage medium 10, having a rectangular metal casing 34 with bolts 36 at each corner.
  • This type of heat storage medium is used when the medium contains particulate matter.

  • the casing has a first end 38 and a second end 40.
  • the second end 40 has a base plate 42 with vents 44 and openings 46 to receive the bolts 36.
  • the heater 12 has a protective coating 48 thereon.
  • the heat storage medium 10 is preferably charged when there is no fluid flowing through the channels 16 by electricity heating the electric heaters.
  • the heat generated by the electric heaters is stored in the heat storage area.
  • the heat storage medium 10 discharges when fluid flows through the channels.
  • the electric heaters do not operate as the heat energy from the heat storage medium is often used to produce electricity or another type of energy during peak power periods.
  • the thermal storage medium 24 is charged by fluid flowing through the channels
  • the fluid is steam or a steam/water combination and in the discharging cycle, the fluid in the inlet is water.
