The blockchain electrifies the electricity industry: It drastically reduces commercial transaction costs. This makes it possible to market even the smallest amounts of electricity. This could enable blockchain to become a key technology for smart grids and sector coupling.
The energy transition needs communication. Between the individual stakeholders and interest groups – as well as in technical terms: To get a grip on the increasing decentralization and fluctuation of power generation, the individual components of the energy system must be linked to each other in smart grids across sectors. This is the prerequisite for the interactions that are necessary between producers and consumers; between equipment, platforms, and systems; between battery storage units and heat pumps, eVehicles, and CHPs. However, how can the countless transactions be efficiently controlled, documented, and calculated in such closely-knit, yet finely divided energy system?
