Method for achieving zero-carbon-emission power generation by fully using renewable energy source

Abstract

The invention provides a method for achieving zero-carbon-emission power generation by fully using a renewable energy source. According to the method, mainly, in the trough period of the renewable energy source, renewable energy power is used for preparing low-temperature liquid oxygen, the renewable energy power is converted into the liquid oxygen to be stored and used, and at the moment, deficient power of the whole power grid is provided by thermal power generation; and in the thermal power generation process, the stored liquid oxygen is converted into gaseous oxygen, the gaseous oxygen andcarbon dioxide are mixed according to a certain proportion and then mixed with fossil or biomass fuel to be combusted for energy conversion power generation, high-concentration carbon dioxide smoke is generated after combustion, the high-concentration carbon dioxide smoke is directly collected, stored and used, and then zero-carbon-emission power generation in the whole thermal power generation field is realized. In the peak period of the renewable energy source, thermal power generation is turned down or stopped. Renewable energy power is fully used through peak regulation by means of thermal power generation, and zero carbon emission in the power generation field is achieved.

Description

Technical field [0001] The present invention is primarily subjected to the field of reducing carbon emissions, and in particular, a method of sufficiently using renewable energy to reach zero carbon emissions power generation. Background technique [0002] Reducing carbon emissions has always been a key topic, which reduces the carbon emissions of fire power generation. At present, there are two ways to reduce the carbon emissions of fire power generation. The first pathway is to reduce carbon emissions by vigorously developing carbon-free renewable energy power generation, reducing carbon emissions, but due to the seasonal, regional, regional, and Load fluctuations, so that how to stably use renewable energy to face challenges; the second way is to upgrade the thermal power generation, capture carbon dioxide produced by fire power generation, reduce carbon emissions, but carbon dioxide capture technology is difficult, not easy to implement. [0003] Therefore, how to fully flexi...

Problems solved by technology

At present, there are mainly two ways to reduce carbon emissions from thermal power generation. The first way is to replace thermal power generation with carbon-free renewable energy and reduce carbon emissions. However, due to the seasonality, regionality, and Large load fluctuations make it a challenge to use renewable energy stably; the second way is to upgrade and transform thermal power generation technology to capture carbon dioxide generated by thermal power generation and reduce carbon emissions, but carbon dioxide capture technology is difficult and difficult to implement
