Hydrogen is expected to play an essential role in the transition to a sustainable energy ecosystem. Offshore generation of green hydrogen and the transportation to shore via (existing) pipelines has several advantages over transporting via electrical cables. Besides reusing existing pipelines reduces the environmental impact, the capacity of pipelines is significantly more extensive, and the permitting and timeline for connection to the onshore backbone is much shorter. Research by the Technical University of Delft has indicated that further than 75 kilometres from the coast, transporting hydrogen molecules is considerably cheaper than transporting electricity via cables: this distance can be even shorter when using existing pipelines.

NGT participates in several offshore hydrogen projects.

How to produce green hydrogen

The primary way to make green hydrogen is through electrolysis, where water (H2O) is split into hydrogen and oxygen. This technology is well known but is mainly applied on land on a small scale. Several research and development projects are working on expanding the size and applying it in an offshore environment. NGT participates in several of these initiatatives. We are a consortium partner in the PosHYdon project and cooperate with the H2opZee initiative.
