Abstract
A heated solid metal object 1 which may be made of iron or aluminium or copper may have an internal chamber 2 with an inlet 3 and an outlet 4 to enable a working fluid 5 to pass through and be heated in the chamber. The heated fluid then flows through the outlet and can then drive a turbine 6 to power an electrical generator 7 and the expanded fluid can then be used as a low grade heat source for cryogenic generators or be used to heat buildings 8. The fluid may be heated electrically 9 along with the solid object 10. The fluid may flow to the solid object by means of a pump 11. The solid object and the fluid store may be insulated. The fluid may be water.
Description
Thermal energy storage This invention relates to storing energy in the form of heat during low demands for energy so that it oan be converted into electricity when there is a higher demand for energy.
As more and more energy is oreated by renewable means there is a need to store this energy when the production is high and the demand is low so that this energy is not wasted. There are many different possibilities for storing energy, and the solution will probably be a mix of these to suit the requirements. One form of energy storage that shows promise is cryogenically frozen air, however it performs best if there is a good temperature gradient such as utilising waste heat from industry which means that it is more restrictive in its location. To overcome this, the present invention proposes a solid metal object, said solid metal object having means to be heated, and means to transfer said heat to a working fluid for the generation of electrical energy and/or mechanical power and/or heat a fluid.
When the metal object is heated it will store this energy in the form of internal energy until it is required in which the working fluid will be heated and can be used to generate electricity or produce mechanical power or heat a fluid as a therrnai gradient.
Preferably, said means to heat said metal object is electrical.
Preferably, said working fluid drives a turbine which drives an electrical generator and/or produces mechanical power.
Preferably, said means to transfer said beat to said working fluid includes at least one internal chamber, said internal chamber fluidly connected to at least one cutlet and at least one inlet wherein said working fluid flows into said inlet, is heated in said chamber and leaves through said cutlet to drive said turbine.
Preferably, there are two or more chambers.
Preferably, there are two or more inlets.
Preferably, there are two or more outlets.
Preferably, said solid metal object is composed of iron and/or aluminium and/or copper.
Preferably, said working fluid is water.
Preferably, said working fluid is stored heated.
Preferably, said solid metal object is insulated.
Preferably, said working fluid is heated electrically. n
Preferably, said working fluid flows to said solid metal object by means of a pump.
Preferably, said heated working fiuid store is insuiated.
Preferably, said solid metal object is in the form of a cylinder.
An example of the invention will now be described by referring to the accompanying drawing: -figure 1 shows a side view of the thermal energy storage according to the invention.
A heated solid metal object 1 which may be made of iron or aluminium or copper may have an internal chamber 2 with an inlet 3 and an outlet 4 to enable a working fluid 5 to pass through and be heated in the chamber.
The heated fluid then flows through the outlet and can then drive a turbine 6 to power an electrical generator 7 and the expanded fluid can then be used as a low grade heat source for cryogenic generators or be used to heat buildings 8. The fluid may be heated electrically 9 along with the solid object 10. The fiuid may flow to the solid object by means of a pump 11. The solid object and the fiuid store may be insulated. The fluid may be water and there may be two or more chambers, inlets and outlets and the objects shape may be a cylinder.
Depending on the material used, the soiid object can be heated to many times the boiling point of water without any pressure issues giving a similar energy density by weight to cryogenicaily frozen air, but with less volume, Coupled with cryogenic gas energy storage they would work together to produce better efficiencies than either on its own, enabling plants to be sited more independently from industrial low grade heat sources.
The pre-heating of the working fluid helps to store more energy and reduces the thermal shock on the solid metal object, giving a greater number of cycles The solid metal object would essentially be a large mass of material with a comparatively small chamber inside resulting in very large wail thicknesses.
The insulation could be in the form of a vacuum which may help reduce oxidisation of the solid metal object.
For manufacturing simplicity a pipe could be wound around the cylinder which then forms the inlet and outlet and the heating chamber for the working fluid, however this may lead to an increase of pressure loss and therefore a decrease in efficiency.
