“Sector coupling” – the interconnection of the electricity, heating, building, transport and – is a reality and no longer a topic of the future.
In order to make efficient use of volatile renewable energies, the flexibility of the sectors must be assessed in an integrative way. For example, wind and solar surpluses can be used to generate “green heat,” or electricity can be stored using hydrogen electrolysis and then used to power a truck. If electricity should ever be in short supply, on the other hand, bidirectionally controlled e-vehicle fleets can contribute to an uninterrupted energy supply in the future. From a system perspective, sector coupling is indispensable, but at the same time it offers companies and pioneers opportunities and possibilities for new business models.
