Problems and Suggestions Regarding Hydrogen Energy as a Sustainable Energy Source

Abstract

As the world accelerates toward the goal of "carbon neutrality," the green transition of energy systems has become an inevitable choice for addressing climate change. Hydrogen energy, with its unique characteristics, is regarded as the "fourth-generation energy" following coal, petroleum, and electricity, playing a crucial role in solving energy and environmental challenges. From Germany's "National Hydrogen Strategy" to Japan's vision of a "Hydrogen Society," and from China's "14th Five-Year Plan" for the hydrogen energy industry to the EU's "Hydrogen Corridor" initiative, major global economies have elevated hydrogen energy to a national strategic level.  The primary objective of this article is to enhance public understanding and knowledge of hydrogen energy, thereby promoting its greater role in sustainable energy systems. The focus of this paper lies in addressing the high costs associated with hydrogen energy transportation and storage.
