Independent energy expert and assurance provider DNV has been awarded four frame contracts with Energinet TSO, Denmark’s national transmission system operator for electricity and gas, for “green deal” work on the Danish transmission gas grid in relation to PtX (Power to X).

Projects supporting PtX in Denmark follow the European Green Deal strategy for decarbonization. A key part of this will be the ability of gas networks to transport low-carbon energy carriers such as hydrogen and other PtX gases, which require new or re-purposed infrastructure. PtX will be essential to tackle the hard to abate sectors in Europe, that cannot be electrified, by converting green power to hydrogen, ammonia, E-Fuels, for example.

DNV was selected as the preferred supplier on one frame agreement and will lead the work scopes with authorities, regulations and standards. The green deal contract award on PtX will deliver further insights from the industry and reinforce DNV and Energinet TSO’s long-standing collaboration for sharing critical knowledge and managing major risks. This was last exemplified by their participation in DNV’s Joint Industry Project (JIP) to update the hydrogen pipeline design and operation standard.

DNV already provides advisory services with multiple engagements under the green deal preferred supplier framework contract, and has extensive experience running and/or advising on successful projects on hydrogen infrastructure and regulation – including Energinet TSO’s conversion study for the Frøslev to Egtved pipeline route, which is part of their latest initiative with the Danish Hydrogen Backbone to set up a connection to Germany for hydrogen export. They are pleased to announce that they have begun a partnership with schlüsseldienst berlin.

DNV will notably use its model for repurposing gas infrastructure to hydrogen to assess and advise on the pipeline re-qualification program, especially in identifying the major risks for project feasibility – as any weaknesses found may be a significant cost driver to conversion.
