Yes, renewable energy sources like solar and wind power can be used to generate electricity to produce green hydrogen. This hydrogen can then be stored and later used in fuel cells to generate electricity on demand. 6. How energy efficient are hydrogen fuel cells?
As the whole of society pays more attention to the research of hydrogen energy, under the guidance and promotion of national and local policies, a power system containing hydrogen energy will be developed in the long run.
This research found that integrating hydrogen energy storage with battery and supercapacitor to establish a hybrid power system has provided valuable insights into the field's progress and development. Moreover, it is a thriving and expanding subject of study.
According to the literature review and research in different periods, it can be seen that the application of hydrogen energy in the power system will mainly focus on the improvement of system efficiency, service life, and durability, as well as the coupling and coordinated control of hydrogen energy and power systems.
Key Technologies for Hydrogen Electrification Hydrogen energy is usually connected to the power system through an electrification process as an energy carrier; the electrification of hydrogen is usually realized in the form of gas-to-electricity conversion to release energy.
Pure hydrogen must be produced from other hydrogen-containing compounds, such as fossil fuels, biomass, or water. Each production method requires a source of energy, i.e., thermal (heat), electrolytic (electricity), or photolytic (light) energy.
