The article focuses on selected issues in the field of shaping the identity of hydrogen clusters in the conditions of the modern energy transformation. In addition to the introduction and summary, it consists of three parts in which the strategic dimension of the energy transformation, the identity of sustainable hydrogen clusters and the practical approach of the public partner to create this identity of eight hydrogen clusters in Poland are characterized. Based on the results of own research, it has been shown that supporting the development of hydrogen clusters by the public partner in the light of ambitious national and European assumptions regarding the sustainable development of the hydrogen economy and hydrogen technologies is a purposeful, organized, individually differentiated and systematically implemented activity. At the same time, the process of shaping the identity of hydrogen clusters is influenced by the macro- and micro-environment as well as the internal environment of these clusters. Due to the fact that a number of identities built at different levels intersect and coexist in the cluster space, not only individual identities of individual units of the heterogeneous cluster community, but also collective identities, including social, sectoral, regional and local identities, therefore the selected issues may be an inspiration for further research in the field of management and quality science.
