The energy sector is undergoing decarbonization, decentralization, and digitalization. This paper explores the application of blockchain in this transition. Based on structured interviews with 15 experts of energy and blockchain in Germany, practical challenges and opportunities are explored from multiple perspectives: technological, economic, social, environmental, and institutional dimensions. A critical identified issue is the matching of regulatory change with technological advancements, potentially facilitated through multi-stakeholder engagement and regulatory sandboxes. At large, this paper aims to contribute with holistic insights and outlooks for blockchain in the energy sector.
