The energy of networking: Sector coupling as a solution approach
Sector coupling describes the approach to closely linking the sectors of electricity, heat, transport and industry, which have so far been considered mostly separately. The aim is to make the potential of renewable electricity generation usable for all areas of energy demand and to sustainably reduce CO₂ emissions. Through this interconnection, the sectors can benefit from each other and increase flexibility in the energy system.
Our Spanish solar project Castillejo has also reached Ready-to-Build status and is expected to go online in 2026. However, the projects show that grid connection is the needless eye for renewable energy projects. That’s why network expansion is so important.
Key sector coupling technologies
Combined heat and power (CHP) generates electricity and usable heat at the same time. Heat pumps use electrical energy to extract heat from air, water or earth. Electromobility connects the electricity and transport sectors - provided that charging times are controlled intelligently. Power-to-liquids (PtL) produces synthetic fuel for air and marine transport. Electricity and heat storage compensate for fluctuations between supply and demand. Bioenergy supplies electricity, heat and fuels at basic load capacity. Digital infrastructure enables demand-based coordination between generation and consumption.
