Problems solved by technology

The disadvantage of the described method is that the configuration of the underground heat exchanger is very complex and there is a risk of starvation of the geothermal potential in the vicinity of the cave due to the cooling
No more detailed evaluation of the method is possible since no parameters are given in terms of temperature and pressure

Embodiment Construction

[0036] In the following application example, the utilization of the thermal potential of the power plant, which is decisive for the application of the method, is emphasized. The corresponding recirculation loops, which are identified with the reference numerals 21 to 24, are highlighted by bold lines in the drawing. All other advantages are immediately apparent to a person skilled in the art without further explanation.

[0037] Parameters that are decisive for the two temperature potentials 423K and 473K, such as the transferred heat, temperature and power, are shown in a table in a self-explanatory form. The particular advantages of the different combinations of potentials are shown in particular from the comparison of the respective variants A and B, which correspondingly utilize a circulation circuit with and without geothermal utilization.

[0038] Firstly, the electrical energy that occurs over time and is not available is used for compression and for intermittently fil...

Abstract

The invention relates to a method and an apparatus for use of the method in order to increase the effective electrical efficiency of power stations by making better use of the thermal potential for electricity generation using supercritical carbon dioxide as the working medium and heat carrier and in order to improve the ecological balance of power stations by reducing the carbon-dioxide emissionand avoiding any NOx emissions by using pure oxygen for combustion, and associated with this a method for the temporary storage of the electrical energy by using amounts of energy which are primarilygenerated regeneratively for the formation of appropriate bulk stores for natural gas (1), compressed air (2) and carbon dioxide (3) and their efficient use in continuous operation and for peak-load operation of power stations.

Description

technical field [0001] The invention relates to a method and a device for improved utilization of the thermal potential of a power station and its surroundings and a related device for reducing emissions of carbon dioxide and NOx to the environment and intermediate storage and reuse of electricity. Background technique [0002] The present invention is a complex system with which the answer to current requirements in terms of energy should be found. Specifically, the device design must meet the following objectives: [0003] Utilize excess generation capacity to create bulk storage and use it to recapture power with high efficiency; [0004] ● Create emission-free power stations; [0005] Use the energy of decompression and the different thermal potentials associated therewith to generate energy; [0006] ●Optimal use of low temperature heat to generate electricity; [0007] Leverage the thermodynamic energy potential of connected devices to improve the electrical effici...
