Yi Baolian: Vigorously develop hydrogen energy to help achieve carbon peak and carbon neutrality

Original title: Yi Baolian, Academician of the Chinese Academy of Engineering: Vigorously develop hydrogen energy to help achieve carbon peak and carbon neutrality

People's Daily Online, Beijing, April 12 (Reporter Du Yanfei) "China’s energy structure is “poor oil, less gas, rich in coal”, no matter from the background of carbon peaking and carbon neutrality, or from ensuring national energy security and reducing the need for fossil fuels.

According to Yi Baolian, the role of hydrogen energy in my country's energy transition mainly includes: achieving large-scale, high-efficiency renewable energy consumption; energy distribution among different industries and regions; acting as an energy buffer carrier to improve the resilience of the energy system; Reduce carbon emissions in the transportation process; reduce carbon emissions in the field of industrial energy use; replace coke in the metallurgical industry to reduce carbon emissions; reduce carbon emissions in building heating.

Talking about the production methods of hydrogen energy in my country, Yi Baolian said that the main sources of hydrogen energy in my country are industrial by-product hydrogen recovery and fossil fuel hydrogen production.

According to Yi Baolian, current renewable energy water electrolysis technologies mainly include steam electrolysis, alkaline water electrolysis and pure water electrolysis.

How to store and transport hydrogen energy after it is produced? "At present, the main hydrogen storage methods include liquid hydrogen storage, high-pressure hydrogen storage, metal hydrogen and compound hydrogen storage.

Talking about the application of hydrogen energy, Yi Baolian believes that fuel cell vehicles are a breakthrough in the application of hydrogen energy.
