Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of electrolytic hydrogen production, and in particular relates to an air water and carbon capture coupled high-temperature electrolytic hydrogen production system. Background Art
[0002] New energy sources such as wind power and photovoltaics are characterized by volatility and intermittency, which poses a major challenge to the safety of the power grid. Electricity-hydrogen coupling technology provides a good solution for the long-term storage and time-space matching of new energy sources. By converting electricity into hydrogen, electricity can be stored in the form of hydrogen energy, which is conducive to the safe, stable and efficient operation of the new power system centered on new energy sources.
[0003] Hydrogen production by water electrolysis is recognized as an important way of converting electricity to hydrogen. Among the current mainstream hydrogen production technologies by water electrolysis, high-temperature hydrogen production by water electrolysis has obvious advantages in terms of power consumption and efficiency, but its high operating temperature (700℃~1000℃) also imposes great restrictions on application scenarios and startup flexibility. Generally speaking, high-temperature hydrogen production by water electrolysis is often used as a matching technology for nuclear power plants, using the high-temperature waste heat generated by nuclear power plants as the main heat source. In the matching scenarios of new energy power generation such as wind power and photovoltaic power generation, the supply problem of high-temperature heat must be solved.
[0004] The main raw material for high-temperature water electrolysis hydrogen production is pure water. However, there is an obvious geographical mismatch between the distribution of new energy sources such as wind power and photovoltaic power and the supply of fresh water in my country. Therefore, in order to promote the large-scale development of high-temperature water electrolysis hydrogen production technology, it is also necessary to solve its dependence on water resources.
[0005] High-temperature electrolysis hydrogen production technology can directly convert carbon dioxide and water into synthesis gas, thus solving the problem of storage and transportation difficulties of hydrogen as a single product. However, the supply problem of carbon dioxide raw materials needs to be solved.
[0006] Direct air water capture technology can directly obtain fresh water resources from the air, an endless resource, and get rid of the dependence of traditional water electrolysis hydrogen production on fresh water resources, greatly improving flexibility. However, this technology has difficulty in desorbing water vapor under low temperature conditions (<15°C), resulting in high energy consumption.
[0007] Direct air carbon capture technology can directly enrich carbon dioxide from the air source, but the carbon material absorbent used in this technology has a high decomposition temperature (~900°C), which also leads to excessive energy consumption. Summary of the invention
