Photovoltaic Green Hydrogen Challenges and Opportunities: A Power Electronics Perspective

Hydrogen is expected to play an important role in the future global energy mix
[3]
. It is a very interesting way to store energy, and it is a zero-emission fuel burned with oxygen. In past years, hydrogen has received high attention around the world as illustrated in
Figure 1(a)
, where it can be seen that an increasing number of countries adopted, or are to adopt, general strategies for hydrogen production
[1]
. At present, a stable and well-defined policy framework is needed to better define rules and regulations for green hydrogen standards that can be agreed around the world
