| Summary: | [Introduction] Fossil fuels and new energy power are facing problems and challenges in utilization and development. In order to solve the problem of carbon emissions in hydrogen production from fossil fuels for traditional refining and chemical enterprises and provide suggestions on the volatility in the development of new energy power, it is necessary to review the application and development of hydrogen preparation technology and the hydrogen network status of traditional refining and chemical enterprises. [Method] The utilization and development of hydrogen power were summarized, and special attention was given to the development of fuel cell electrolysis for hydrogen production technology. The hydrogen network in refining and chemical enterprise was in-depth analyzed from hydrogen production, hydrogen utilization, and hydrogen purification points of view. [Result] Based on these, the research points out the idea of combining the waste renewable energy power with the hydrogen network in refining and chemical enterprises by the water-electrolytic hydrogen production technology. With the clean energy device settled near the traditional refinery and chemical enterprise, the daily electricity requirement is satisfied and the processes hydrogen need is met. [Conclusion] To reduce the CO2 emissions from fossil fuel usage and the volatility of renewable energy power usage and to realize the idea of applying water-electrolytic hydrogen production technology in traditional refinery and chemical enterprises, there are still many challenges to overcome.
