[0031] Among them, the new energy system is connected to the power grid system, the electric heating system and the electrolysis hydrogen production system respectively; the electric heating system is connected to the carbon conversion system; the electrolysis hydrogen production system is connected to the carbon conversion system; the thermal power generation system is connected to the power grid system and the carbon capture system respectively; and the carbon capture system is connected to the carbon conversion system.

[0032] In one embodiment, the power grid system, the electric heating system, the carbon conversion system, the electrolytic hydrogen production system and the carbon capture system are respectively connected to the user end to deliver the energy produced by each system to the user end.

[0033] In some embodiments, the new energy power generation system is used to supply power to one or more of the power grid system, the electric heating system, and the electrolysis hydrogen production system. In one embodiment, the electric energy generated by the new energy power generation system is used to feed into the power grid, generate electric heating, and produce hydrogen by electrolysis. Preferably, the electric energy generated by the new energy power generation system is used in the order of primary to secondary, namely, feeding into the power grid, generating electric heating, and producing hydrogen by electrolysis.

[0034] In some embodiments, the electric heating system is used to process the amount of electricity generated by the new energy power generation system that is greater than the amount required by the power grid system for electric heating to generate thermal energy when the amount of electricity generated by the new energy power generation system is greater than the amount required by the power grid system. In one embodiment, when the amount of electricity generated by the new energy power generation system is greater than the amount required by the power grid system, the electricity that is greater than the amount required by the power grid system is sent to the electric heating system for heating, the heat is stored in the heat storage bricks, and the heat in the heat storage bricks is extracted with water as a working medium, and the generated hot water is sent to the heat pipe network for use by the user end.

Thus, energy complementarity is achieved, wind and solar resources are fully utilized, electricity is continuously output, and the produced electricity can be efficiently utilized, the whole process of thermal power generation is efficient and low-emission, and electricity and heat can be provided to users stably and continuously for a long time.

[0040] It should be noted that this application is not limited to Figure 1 The energy complementary system shown may be any system, device, framework, etc. that can implement the business logic of the present application. Figure 1 This is for illustrative purposes only.

[0041] In some embodiments of the present application, the power generation mode of the new energy power generation system is one or more of wind power generation and photovoltaic power generation. Of course, the embodiments of the present application do not limit the new energy to wind power and photovoltaic power generation, and all new energy in related technologies and subsequent technologies are applicable to the present application.

[0042] In some embodiments of the present application, the electric heating method of the electric heating system includes a combination of one or more of resistance heating, induction heating, infrared heating, and dielectric heating in any proportion. In one embodiment,

[0043] In some embodiments of the present application, the method of producing hydrogen by the hydrogen electrolysis system includes a combination of one or more of alkaline electrolysis of water, acidic electrolysis of water, neutral electrolysis of water, and solid oxide electrolysis of water in any proportion.

[0044] In some embodiments of the present application, the carbon capture method of the carbon capture system includes a combination of one or more of a physical adsorption method and a chemical adsorption method in any proportion.

[0045] In some embodiments of the present application, the carbon capture system is also used to purify the flue gas generated by the thermal power generation system; the purification process includes denitrification, desulfurization and dust removal.

[0046] In some embodiments of the present application, the denitrification method is one or more combinations of selective catalytic reduction flue gas denitrification and selective non-catalytic reduction denitrification systems.

[0047] In some embodiments of the present application, the desulfurization method is a combination of one or more of a wet desulfurization method, a dry desulfurization method, and a semi-dry desulfurization method.

[0048] In one embodiment, during thermal power generation, after the flue gas is subjected to selective non-catalytic reduction denitrification, wet desulfurization, and dust removal purification, an ethylenediamine solution is used to absorb and enrich the carbon dioxide in the flue gas, and then thermal desorption is performed to obtain high-purity carbon dioxide, and then the carbon dioxide and hydrogen undergo a thermochemical reaction to generate methanol.

[0049] In the embodiments of the present application, an energy complementary system is proposed to achieve clean, low-carbon production and efficient utilization of energy, so that the entire life cycle of energy presents the characteristics of high efficiency and low emissions.

[0054] The heat required for carbon conversion is supplied by the thermal energy generated by electric heating.

[0055] from Figure 2 It can be seen from the method shown that when the power generation of the new energy power generation system is greater than the power grid system demand, the excess power is converted into thermal energy. If the thermal energy is saturated, the excess power is electrolyzed to produce hydrogen to generate hydrogen; when the power generation of the new energy power generation system is less than the power grid system demand, the thermal power generation system is combined to supply power to the power grid system; and the carbon generated by the thermal power generation system is captured by the carbon capture system, and finally the carbon and hydrogen are converted by the carbon conversion system to generate carbon-based chemicals. Thus, energy complementarity is achieved, wind and solar resources are fully utilized, electricity is continuously output, and the produced electricity can be efficiently used. The whole process of thermal power generation is efficient and low-emission, and electricity and heat can be provided to users stably and continuously for a long time.

[0056] In order to fully illustrate the energy complementation method provided in the embodiment of the present application, Figure 3 To explain:

[0057] The electricity generated by the new energy power generation system is sent to the power grid. If the electricity generated by the new energy power generation system meets the demand of the power grid system, it will be directly sent to the user end. If the electricity generated by the new energy power generation system is greater than the demand of the power grid system, the excess electricity will be converted into thermal energy for users to use. If the thermal energy is saturated, the excess electricity of the new energy power generation system will be electrolyzed to produce hydrogen for users to use. If the electricity generated by the new energy power generation system does not meet the demand of the power grid system, thermal power generation will be carried out through the thermal power generation system, and the electricity generated by thermal power generation will be sent to the power grid. The carbon generated in the thermal power generation process and the hydrogen generated by electrolysis of hydrogen are converted into carbon to generate carbon-based chemicals for users to use.

[0058] In the embodiments of the present application, through energy complementarity, wind and solar resources are fully utilized, electricity is continuously output, and the produced electricity can be efficiently utilized. The entire process of thermal power generation is efficient and low-emission, and electricity and heat can be provided to users stably and continuously for a long time.
