District energy is about securing an energy-efficient heating and cooling supply through a collective system. Denmark’s increase in energy efficiency and reduction in carbon emissions can largely be attributed to the wide-spread adoption of district heating and combined heat and power systems.

Grid and infrastructure are about ensuring a robust and reliable energy distribution system that can support a sustainable and efficient power supply. By integrating renewable energy sources and implementing advanced monitoring and control systems, Denmark has been able to maintain a high level of energy security while reducing greenhouse gas emissions.

Energy storage is about providing a reliable means to store and manage energy, ensuring a consistent and flexible power supply. Denmark's innovation in energy storage solutions, including advanced battery technologies and thermal storage systems, has significantly enhanced the stability and efficiency of its energy grid.

Sector coupling, also known as sector integration, presents a transformative approach to efficiently harnessing renewable energy sources. Referring to the integration of the electricity, heating, cooling and mobility sectors, sector coupling allows us to maximise the use of renewable energy, enhance energy efficiency and create a more flexible and resilient energy system.
