"Sector coupling can contribute to the cost-efficient decarbonisation of the energy system, by valuing synergy potentials and interlinkages between different parts of the energy system. In this study, we distinguish two types of sector coupling: end-use sector coupling and cross-vector integration." [Van Nuffel, L., Dedecca, J.G., Smit, T., Rademaekers, K., 2018. Sector coupling: how can it be enhanced in the EU to foster grid stability and decarbonise? (Study Requested by the ITRE committee).

Originally, sector coupling referred primarily to the electrification of end-use sectors like heating and transport, with the aim of increasing the share of renewable energy in these sectors (on the assumption that the electricity supply is, or can be, largely renewable) and providing balancing services to the power sector. More recently, the concept of sector coupling has broadened to include supply-side sector coupling. Supply-side integration focuses on the integration of the power and gas sectors, through technologies such as power-to-gas." "To distinguish between coupling of end-use sectors with the energy (mainly electricity) supply sector on the one hand and further coupling of the energy (mainly electricity and gas) supply sectors on the other hand, we will refer to these two strategies as 1) end-use sector coupling and 2) cross-vector integration. This is a pragmatic approach to highlight these complementary strategies, but other categorisations are possible." {{ :sectorcoupling.png?600 |}} [Van Nuffel, L., Dedecca, J.G., Smit, T., Rademaekers, K., 2018.

Connecting these three sectors will be crucial for the energy transition’s success. The term describing this is “sector coupling” (or “Sektorkopplung” in German)." "**Electrification is one example** of sector coupling. For instance, solar and wind power are the two fastest growing sources of renewable energy worldwide. Eventually, a growing number of countries will begin to have excess amounts of this green electricity when the sun is shining and the wind is blowing. At that point, electricity will be inexpensive on wholesale markets, so it will increasingly be used to generate heat for use in buildings and industry. The German Energy Management Act now incentivizes sector coupling (power-to-heat) in combination with cogeneration units."

Therefore, sector coupling is equivalent to **power to gas**. **Sector integration** is understood by the EC to mean the **usage of final energy** (i.e. electricity or gas) in the end use, which includes, for example, the **transport or heating sector**. Both require ‘hardware’ and an adequate legal and regulatory framework."
