Description

technical field [0001] The invention relates to the electrolytic hydrogen production industry, in particular to a system for generating electrolytic hydrogen using clean energy and mixing it with a gas pipeline network. Background technique [0002] Hydrogen production by electrolysis of water is an efficient and clean hydrogen production technology. The hydrogen production process is simple and the product purity is high. The purity of hydrogen and oxygen can generally reach 99.9%. It is the most potential large-scale hydrogen production technology. Especially with the current increase in clean energy power generation, hydrogen will become an ideal carrier for electrical energy storage. Through the hydrogen production technology of clean energy power generation through electrolysis of water, the electric energy generated by clean energy is converted into hydrogen energy for storage, and according to actual needs, hydrogen energy can also be converted into methane, methanol ...

Problems solved by technology

Although this patent utilizes wind energy, it needs to use electric energy to produce high-temperature water vapor first, which makes the system efficiency of the entire hydrogen production system low and cannot be suitable for large-scale hydrogen energy production.
