Blockchain-enabled business model innovation in sector-coupled energy communities.

This paper analyses business model innovation and digital platform alignment-including blockchain-enabled remuneration and automated settlement-in sector-coupled energy communities. Drawing on six diverse pilot deployments, we explore how modular digital platforms and blockchain technologies can support peer-to-peer trading, flexibility services, and integration across electricity, heating, and mobility sectors. The methodology combines systematic value proposition mapping with technical and market analysis to assess real-world user needs, operational challenges, and regulatory barriers. Findings show that blockchain and digitalisation can improve transparency and trust in community energy markets, but effective scaling requires regulatory adaptation, flexible business models, and sustained user engagement. The results provide actionable insights for both practitioners and policymakers aiming to advance digital innovation and business model alignment in the evolving landscape of energy communities.
