 +<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.

 +===== Shared definitions =====

 +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))
 +
 +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))
 +
 +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))
 +
 +  * **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.

 +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))
