Claudio Lima explains how blockchain technology can be used to digitize and foster growth in the energy sector. DLT has the potential to optimize energy management processes and to deal with the growing complexity in the decentralized energy system. Lima introduces the IEEE P2418.5 Standard for Blockchain in Energy, which creates an industry framework that will help with interoperability among different blockchain use cases and technologies. A DLT layer complements existing smart grid architectures, improves grid security and efficiency, and reduces the costs of utility operation.
