Blockchain in energy: literature review in the context of sustainability

This paper has two equally important research objectives. The first aim of the research is to identify key research areas addressed in scientific publications that simultaneously relate to blockchain, energy, and sustainability. In turn, the identification of green research areas in these publications is the second research aim. The indicated research aims were achieved on the basis of a bibliometric review of 205 scientific publications from 2017-2023 (Scopus database). By means of a systematic literature review, 25 different key research areas were identified. In turn, the classic literature review identified 18 green research areas (e.g. green blockchain). At the same time, no green issue was identified as a key research area. The results can inspire researchers looking for research gaps around blockchain and sustainability issues. Among the recommendations for stakeholders, the need for further research around blockchain technology, the development of a regulatory framework, or educational issues were highlighted.
