Finding nature-friendly replacements for fossil-fuels based energy sources are considered vital, and such a task becomes critical for sustainable development. In this regard, hydrogen carries a significant weight potentially and becomes an essential driver in transitioning the economic sectors to carbon-free ones. While the world experiences this kind of transition with hydrogen, Canada appears to be among top ten countries conducting research, development and innovation activities extensively on hydrogen and intending to make hydrogen a key player in their green energy transition. In this study, the contributions of Canadian academic institutions, research centers and other organizations to hydrogen-related research, development and innovation activities over the last fifty years are studied and evaluated comparatively. A comprehensive literature search is conducted to identify the number of hydrogen-related research articles, books, dissertations, patents and funded projects affiliated with Canadian institutes. The findings are presented graphically and discussed from various perspectives. The conducted literature search results show that Canadian institutes have contributed to hydrogen research with a total of 112,454 scholarly publications from 1971 to 2021. During period, the number of hydrogen-related academic articles and books has become 108,437 and 2995, respectively. In the subject area of energy, the relatively young Canadian institution, Ontario Tech University, has contributed the highest to hydrogen research in Canada by producing about 11% of academic articles and about 27% of books, book chapters, and editorials in the subject matter field of hydrogen research and development activities.

为基于化石燃料的能源寻找自然友好的替代品被认为至关重要，而这样的任务对于可持续发展至关重要。在这方面，氢具有潜在的重要意义，并成为将经济部门转变为无碳部门的重要驱动力。虽然世界正在经历这种氢能转型，但加拿大似乎是在氢能领域开展广泛研究、开发和创新活动的十大国家之一，并打算使氢能成为其绿色能源转型的关键参与者。在这项研究中，加拿大学术机构、研究中心和其他组织在过去五十年中对氢相关研究、开发和创新活动的贡献进行了比较研究和评估。进行了全面的文献搜索，以确定与加拿大机构相关的氢相关研究文章、书籍、论文、专利和资助项目的数量。调查结果以图形方式呈现，并从不同的角度进行了讨论。进行的文献检索结果显示，从1971年到2021年，加拿大机构对氢研究做出了贡献，共发表了112,454篇学术论文。在此期间，与氢相关的学术文章和书籍的数量分别为108,437和2995篇。在能源学科领域，相对年轻的加拿大机构安大略理工大学对加拿大的氢研究贡献最大，发表了约 11% 的学术文章和约 27% 的书籍、书籍章节、
