Alliander N.V. has issued a significant tender titled “Wide Range Couplings,” published on March 18, 2025.
The submission deadline for this tender has not been explicitly mentioned in the document. This tender is crucial for the hydrogen industry as it involves components vital to blending existing natural gas infrastructure with hydrogen, enhancing the move towards sustainable energy solutions.
The primary objective of this tender is to procure various types of Wide Range Couplings. These components are essential for connecting steel, cast iron, and PE pipelines to new pipeline materials like PE and impact-resistant PVC. These couplings must be capable of handling transitions between different nominal diameters. The specific requirements include certifications with the GASTEQ QA KE 208 and KE 214 quality marks or their equivalents. A critical component of this tender is that all couplings must be suitable for blending with up to 100% hydrogen gas. The planned expenditure for this requirement is 7.8 million euros, with a need for 27,209 coupling units over eight years.
This tender is significant as it supports the hydrogen infrastructure by replacing obsolete pipeline materials, such as grey cast iron and asbestos cement. By ensuring compatibility with hydrogen, it aligns with future energy distribution needs, emphasizing sustainability and energy transition. The procurement supports Alliander’s strategic plan as a grid operator to upgrade and maintain a resilient infrastructure capable of integrating renewable energy sources.
The technical requirements specify that the couplings must be certified to high standards to ensure safety and efficiency when blending with hydrogen. Ensuring that these couplings can handle hydrogen enhances the safety and efficiency of future gas networks.
