Transmission and distribution system operators (TSOs and DSOs) in the natural gas sector are under increasing pressure to reduce CO2 emissions and increase access to the natural gas infrastructure for renewable gases. However there are currently no existing guidelines for the preparation of these networks for the injection of hydrogen produced from renewable sources. To address this, DNV GL has initiated a global joint industry project (JIP) ‘HYREADY’. Stakeholders from the natural gas value chain, including natural gas TSOs and DSOs, and technology providers have already signed up. The project remains open for other participants to join.
The ‘HYREADY’ initiative will encourage the industry to ‘be ready for hydrogen’ by developing practical processes and procedures for the introduction of hydrogen to the grid. The project partners will work together to deliver a broadly accepted methodological description of the steps and aspects to be considered by TSOs and DSOs across the globe on the measures they could take to prepare natural gas grids for hydrogen injection with acceptable consequences.
“We have seen an increasing number of projects needing access to natural gas infrastructure for renewable gases,” says DNV GL project manager Onno Florisson. “With multiple organisations having the same objective, our industry guidelines will address the ‘how-to’ questions for gas system operators so that they can be confident both in preparing their natural gas grids for the accommodation of hydrogen and in the consequences related to hydrogen injection.”
