Title:
MULTI-ENERGY SUPPLEMENTARY POWER GENERATION SYSTEM WITH METHANOL AS CARRIER AND WORKING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/199327
Kind Code:
A1
Abstract:
A multi-energy supplementary power generation system with methanol as a carrier and a working method therefor. The present invention belongs to the technical field of the coal chemical industry. The system comprises a new energy power generation unit, a water electrolysis unit, an oxygen collection unit, a hydrogen collection unit, a carbon-dioxide-to-methanol unit, a methanol storage unit, a water treatment unit, and a fuel power generation unit. In the present invention, methanol is used as a carrier for energy storage. When there is a surplus of electric power, the electrolysis of water into hydrogen is used to generate methanol with carbon dioxide for energy storage; and when the electrical power supply is insufficient, methanol is used for power generation, and the generated electricity is used for supplementing a gap in new energy power generation. Methanol is high in energy density and energy storage capacity, and no battery life and recovery problems exist. The utilization efficiency of the energy is improved, the technical development of new energy power generation is promoted, and new energy power generation and the stability of a power supply system are facilitated; in addition, the conversion and utilization of carbon dioxide are also achieved, the advantages of being environmentally friendly and free of pollution of new energy power generation are fully exploited, and the operation cost is reduced.
