-===== Sector coupling and its relation to energy system integration [European Parliament, ITRE 2018] =====+<WRAP insight> 
 +Sector coupling connects electricity, heat, transport, and gas to enable cost-efficient decarbonisation and grid flexibility, but the term covers two distinct strategies that are often conflated. 
 +</WRAP>
  
-"Sector coupling is a concept that has been developed in Germany but has been gaining attention elsewhere in Europe. +===== Why this matters =====
-  +
-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." +

-===== End-use sector coupling and Cross-vector integration [European Parliament, ITRE 2018] =====+===== Shared definitions =====
  
-"**End-use sector coupling** involves the electrification of energy demand while reinforcing the interaction between electricity supply and end-use. +Sector coupling involves the increased integration of energy end-use and supply sectors with one another. It can contribute to the cost-efficient decarbonisation of the energy system by valuing synergy potentials and interlinkages between different parts of the energy system.((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?// European Parliament, Committee on Industry, Research and Energy (ITRE). https://www.europarl.europa.eu/RegData/etudes/STUD/2018/626091/IPOL_STU(2018)626091_EN.pdf))
-  +
-**Cross-vector coupling** involves the integrated use of different energy infrastructures and vectors, in particular electricity, heat and gas, either on the supply side, e.g. through conversion of (surplus) electricity to hydrogen, or at the demand side, e.g. by using residual heat from power generation or industrial processes for district heating." +

-===== Sector Coupling [wiki.energytransition.org/glossary] =====+The concept originated in Germany, where it referred primarily to the electrification of end-use sectors such as heating and transport, with the aim of increasing the share of renewable energy in those sectors and providing balancing services to the power sector. More recently the concept has broadened to include supply-side integration between the electricity and gas sectors.((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?// European Parliament, ITRE. https://www.europarl.europa.eu/RegData/etudes/STUD/2018/626091/IPOL_STU(2018)626091_EN.pdf))
  
-"Energy is consumed in three sectors:  transportation, industry, and to heat and cool buildings. Connecting these three sectors will be crucial for the energy transition’s success. The term describing this is “sector coupling” (or “Sektorkopplung” in German)." +Two complementary strategies can be distinguished:((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?// European Parliament, ITRE. https://www.europarl.europa.eu/RegData/etudes/STUD/2018/626091/IPOL_STU(2018)626091_EN.pdf))
-  +
-"**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." +

-===== Definition of Sector Coupling and Sector Integration [ENTSO-E 2019] =====+  * **End-use sector coupling** involves the electrification of energy demand while reinforcing the interaction between electricity supply and end-use sectors such as heating and transport. 
 +  * **Cross-vector integration** involves the integrated use of different energy infrastructures and vectors, in particular electricity, heat, and gas, either on the supply side through conversion of surplus electricity to hydrogen, or on the demand side through use of residual heat from power generation or industrial processes for district heating.
  
-"**Sector coupling** is defined by the EC as closely linking the electricity and gas sectors, both in terms of their markets and infrastructure. Therefore, sector coupling is equivalent to **power to gas**. +<WRAP figure> 
-  +{{sectorcoupling.png?700|Sector coupling: end-use sector coupling and cross-vector integration}}
-**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." +

 +ENTSO-E distinguishes between sector coupling and sector integration more precisely: sector coupling refers specifically to the close linking of the electricity and gas sectors, equivalent to power-to-gas, while sector integration refers to the use of final energy in end-use sectors including transport and heating.((ENTSO-E. (2019). //Sector coupling and sector integration: Position paper//. European Network of Transmission System Operators for Electricity. https://eepublicdownloads.entsoe.eu/clean-documents/Publications/Position%20papers%20and%20reports/Sector_coupling_integration_PositionPaper.pdf)) Both strategies require hardware and an adequate legal and regulatory framework.

 +<WRAP distinction>
 +**Sector coupling vs. sector integration** \\
 +In ENTSO-E's framing, sector coupling refers specifically to linking electricity and gas markets and infrastructure (power-to-gas), while sector integration refers to the use of electricity or gas in end-use sectors such as transport or heating. In the broader European Parliament framing, both are subsets of sector coupling. The distinction is not universally applied but matters when specifying the technical or regulatory scope of a measure.((ENTSO-E. (2019). //Sector coupling and sector integration: Position paper//. ENTSO-E. https://eepublicdownloads.entsoe.eu/clean-documents/Publications/Position%20papers%20and%20reports/Sector_coupling_integration_PositionPaper.pdf))
