Energy consuming is an essential issue to all human beings. Along with the emerging threat of environmental crisis, finding out the most efficient and effective way to use the limited energy is becoming an urgent issue to the world. Hydrogen is one of the most well-known alternatives to the present energy. The difficulty of developing hydrogen storage technologies is one of major factors hindering the utilization of hydrogen energy into people's daily lives. To conduct a research regarding technology development of hydrogen storage has an extraordinary meaning. The present study implements a deep and comprehensive patent analysis, which is devoted to recognizing the building blocks constituting the technologies of hydrogen storage. The scope of this study is limited to the countries which are the best players of developing hydrogen storage technology, i.e. United States, Canada, Japan, and European Union. By means of data collection from the major patent databases of each country, this research has plenty of resources which not only improve the completeness of the study but also help generate valuable insights. With the result provided by this study, energy researchers could easily identify the most potential technology trajectory and improve the quality and utilizability of the research output.
