The Role of Green Hydrogen
Green hydrogen, produced through electrolysis using renewable energy sources, plays a central role in sector coupling. As a versatile energy carrier and raw material, hydrogen enables the storage and transport of energy across sector boundaries.
- In the electricity sector, it serves as long-term storage for fluctuating renewable energy sources
- In the heating sector, it can be used in fuel cells or through direct combustion to generate heat.
- In the mobility sector, green hydrogen is used in fuel cell vehicles and in the production of synthetic fuels.
- In the industrial sector, it serves as a CO₂-neutral raw material, for example in steel production or the chemical industry.
Closely linked to the concept of sector coupling is the Power-to-X concept, according to which hydrogen serves as the bridge between the “world of electrons” and the “world of molecules.”
Challenges and Opportunities
Implementing sector coupling requires both technological innovations and regulatory adjustments. Technical prerequisites include Power-to-X technologies, smart grids, and advanced storage systems. From a regulatory perspective, this requires the harmonization of energy markets, the adjustment of taxes and levies, and the creation of incentives for cross-sector investments.
A major challenge of sector coupling lies in the high complexity of the overall system. In addition, major infrastructure adjustments are necessary, which in turn require significant initial investments. Nevertheless, sector coupling offers significant potential for increasing system efficiency, reducing greenhouse gas emissions, and enhancing security of supply.
