Independent energy expert and assurance provider DNV will work with Denmark’s national transmission system operator electricity and gas, Energinet TSO (Energinet), to advance the country’s Power to X (PtX) ‘green deal’ projects.

After being awarded four frame contracts with Energinet, DNV will lead the work scopes relating to authorities, regulations, and standards for the scaling up of PtX projects. 

This will enable the country to follow the European Green Deal strategy for decarbonisation, which includes optimising gas networks to transport low-carbon energy carriers such as hydrogen and other PtX gases, which require new or re-purposed infrastructure. 

PtX is considered essential to decarbonising hard-to-abate sectors in Europe that are resistant to electrification. This works by converting green power to clean energies such as hydrogen, ammonia, and e-fuels. 

What is Power-to-X?

As defined by Michael Sterner, a professor at OTH Regensburg University in Regensburg, Germany, power-to-X is “the means to convert electricity, understood to be primary energy, into an energy carrier, heat, cold, product, or raw material. It is an umbrella term for different ways of generating energy, namely power-to-gas, power-to-liquid, power-to-fuel, power-to-chemicals and power-to-heat.”

Commenting on the agreement, Prajeev Rasiah, Executive Vice President for Energy Systems, Northern Europe, DNV, said, “In Denmark, EU green deal projects, such as the ones converting and extending transmission infrastructure are essential for a successful energy transition.” 

“DNV’s Energy Transition Outlook shows that connecting supply and demand for hydrogen, ammonia, and other e-fuels is key to providing consumers with easier access to cleaner energy, and we are proud to take part in the realisation of this objective.” 

The deal comes after a previous agreement which saw Energinet take part in DNV’s Joint Industry Project to update the hydrogen pipeline design and operation standards. 

In addition to using its experience garnered from previous advisory services and running and/or advising on successful hydrogen infrastructure and regulation related projects, DNV aims to use its model for repurposing gas infrastructure to assess and advise on the pipeline re-qualification programme. 

This will involve the identification of major risks for project feasibility. 

“The gas transmission network is a critical park in Denmark for transporting energy and helping industry sectors in alignment with EU green deal strategy,” stated Peter Hodal, CEO, Energinet Gas Transmission. 

Successful repurposing of Denmark’s gas network will increase the possibility of hydrogen being used to advance a clean energy future and decarbonise notoriously hard-to-abate sectors.
