Replacing natural gas by hydrogen in the existing DSO infrastructure will give several challenges on the security of supply of energy to the end-users, related to the physical aspects of the assets in the hydrogen network. Within the HyDelta2 program, WP8 Digitalization, the need and benefit of digitalization of the gas grid has been investigated. In the current gas grid the digitalization is limited in all aspects: monitoring, modelling and control. This means that a lot of digitalization aspects could be developed to handle the needs of a future hydrogen grid, which have to deal with the following trends: increasing dynamics in supply and demand, from a stand-alone grid to a multi-connected grid and a need for real-time data on supply and demand. A roadmap has been developed on how to deal with the main challenges in balancing the future hydrogen grid, for all aspects of digitalization. In the frame of the HyDelta2 program we have chosen for the use case ‘Smart sensor placement’ for pressure and flow ... : Dit project is medegefinancierd door TKI Nieuw Gas | Topsector Energie uit de PPS-toeslag onder referentienummer TKI2022-HyDelta. ...
