Natural gas is the most climate-friendly fossil energy source and essential for the successful implementation of Germany’s energy transition. Millions of households, commercial and industrial customers value natural gas as a safe source of energy and around 50 percent of all households in Germany are heated by natural gas. Currently, two different kinds of natural gas, which differ in particular in the methane content, are used throughout Germany: L-gas (low calorific gas) and H-gas (high calorific gas). More than five million household appliances for heating, hot water and industrial use are currently operated with L-gas throughout Germany. This is a share of around 25 percent of the total market. Nevertheless, by 2030 the portion of L-gas will fall by about 90 percent, mainly due to the decreasing gas reserves in Germany and the Netherlands.

To ensure that proven natural gas technologies can continue to be combined with renewable energies, households, commercial and industrial customers must be converted to the higher-quality H-gas – and also the gas grids in front of it. The ZEELINK transmission line will be an important part of this changeover.

The ZEELINK project includes the construction of the new ZEELINK pipeline from the Belgian-German border at Lichtenbusch to Sankt Hubert near Krefeld and on to Legden near Ahaus in North Rhine-Westphalia. The new pipeline thus makes an important contribution to security of supply in Germany and increases the transport capacity of natural gas from the north to the south.

Mannesmann Grossrohr GmbH is providing approximately 216 km of gas pipeline pipes with a diameter of 1,016 mm (DN 1000). Pipes for specific trenchless sections will be coated by TDC’s reliable pau wrap® TL 5.0mm mechanical protection coating. We look forward to continuing our work on the ZEELINK project, contributing to sustainable and environmentally friendly energy supply solutions.
