Sector coupling! Huh?

This is why electricity, heat and electromobility should be linked together

While an engineer simply nods knowingly when the buzzword "sector coupling" is mentioned, the reaction among the general public and in non-scientific faculties is likely to be rather different. For example, with a subtle: Huh?

The term "sector coupling" (sometimes also referred to as sector coupling) is quite easy to grasp.

Prof. Haim and Volker Brade from the "Networked Mobility" sub-project of Saxony5 explain it like this:

"A large proportion of heat generation in households, businesses and transport is still fossil-based. Unlike in the electricity sector, very little renewable energy is still used here. However, if, for example, solar power or the "waste" heat produced during electricity generation in mini-CHP units (combined heat and power plants) is used for heating, for example, this helps with the energy transition in heat generation. In rural areas in particular, photovoltaics and the additional use of battery storage systems can create a self-sufficient electrical energy supply that offers many advantages. At the same time, this can also reduce the load on the electricity grids. Ideally, the large batteries in electric cars will take on precisely this function in the future"

This means that the "heat", "electricity" and "e-mobility" sectors, among others, are becoming increasingly interlinked and "help each other out". In this way, the fluctuations in the electricity grid caused by renewable energies can be better balanced and efficiency levels improved.

At the HSZG, Prof. Haim and Volker Brade, among others, are working with researchers from the other four Saxon universities of applied sciences to find out exactly what such an intelligent link could look like. This will all become tangible in the e-mobility laboratory of the "Networked Mobility" Co-Creation Lab, a sub-project of Saxony5, which is due to open soon.

An explanatory video on "sector coupling" has now been created in close cooperation between Zittau/Görlitz University of Applied Sciences and Mittweida University of Applied Sciences:

Saxony⁵ is a joint project between five Saxon universities: Zittau/Görlitz University of Applied Sciences, HTW Dresden, HTWK Leipzig, Westsächsische Hochschule Zwickau and Mittweida University of Applied Sciences. The aim of this project is to find new innovative solutions for knowledge and technology transfer.
