Energy system based on renewable energy and hydrogen energy methylation and energy utilization method

Abstract

The invention discloses an energy system based on renewable energy and hydrogen energy methanation and an energy utilization method. The energy system comprises a renewable energy power generation system, a water electrolysis system, a biomass oxygen-enriched combustion system, a methanol synthesis system, a liquid fuel storage and transportation system, a methanol reforming system and a gas-steam combined cycle power generation system, wherein most of electric energy generated by the renewable energy power generation system is used for being electrolyzed in the water electrolysis system to generate hydrogen and oxygen, the oxygen and biomass fuel are sent to the biomass oxygen-enriched combustion system together to generate the electric energy and carbon dioxide, and the hydrogen and the carbon dioxide pass through the methanol synthesis system together to generate methanol. Methanol serving as liquid fuel is conveyed to various places through the liquid fuel storage and transportation system. Methanol can be converted into hydrogen through the methanol reforming system, the hydrogen is used as fuel, and power can also be generated through the gas-steam combined cycle power generation system.

Description

technical field [0001] The invention belongs to the field of energy power generation, and relates to an energy system and an energy utilization method based on renewable energy and hydrogen energy methanolization. Background technique [0002] In recent years, with the rapid development of human society and economy, the consumption of a large amount of fossil fuels has led to the emission of a large amount of greenhouse gases, resulting in global warming and frequent extreme climates. In order to protect the environment on which human beings live, reducing the emission of greenhouse gases has become an urgent task for human beings. In 2020, my country announced that carbon dioxide emissions will peak before 2030, and strive to achieve carbon neutrality before 2060. To achieve this goal, the key lies in reducing the use of fossil energy, which makes the development of renewable energy the main trend of future energy development. my country has clearly pointed out that by 20...
