D5e.2 Improving ventilation in hydrogen pressure regulation stations

Abstract

In Nederland staan bij benadering ongeveer 60.000 gasdrukregelstations. Elk station wordt geplaatst in een behuizing die de technische installatie afschermt van de omgeving. Ventilatie is een mitigerende maatregel voor een operationeel gaslek in een gasdrukregelstation. In Nederland zijn de ventilatie-eisen voor gasdrukregelstations voor aardgas vastgelegd in de NEN1059. Daarin staat in tabel 3 beschreven welke minimale ventilatie vereist is voor het ventileren van de behuizing van een gasdrukregelstation. Tijdens HyDelta 1.0 en 2.0 [1, 2] zijn verschillende experimenten uitgevoerd om inzicht te krijgen in de ventilatie eigenschappen van de behuizingen in het geval van waterstof distributie. Hierbij is gebruik gemaakt van representatieve behuizingen toegepast door de Nederlandse gasnetbeheerders, waarbij een 1/2m³ kast en een 4m³ kaststation zijn beproefd bij verschillende lekdebieten voor zowel aardgas als waterstof. Daarbij hebben de gekozen lekdebieten deels overlap in grootte. Tijdens deze onderzoeken is aangetoond dat bij het gebruik van waterstof het verbeteren van het ventilatieconcept wenselijk is. Door het vergroten van de ventilatieopeningen van een bestaande behuizing kan de ventilatie verbeterd kan worden waardoor de evenwichtsconcentratie lager uitvalt bij eenzelfde lekkage, zodat deze adequaat kan ventileren voor een toepassing met waterstof. Dit is ook de reden dat vergroten van ventilatie in dit rapport wordt genoemd als een “quick-win”. Dit project is medegefinancierd door TKI Nieuw Gas | Topsector Energie uit de PPS-toeslag onder referentienummer TKI2023-HyDelta. De Engelse vertaling van dit rapport wordt nog gepubliceerd als een nieuwe versie van dit Zenodo record.

In the Netherlands, there are approximately 60,000 gas pressure regulating stations. Each station is placed in a gas cabinet that shields the technical installation from the public environment. Ventilation is a mitigating measure for an operational gas leak in a gas pressure regulating station. In the Netherlands, the ventilation requirements for gas pressure regulating stations for natural gas are described in the NEN1059. Table 3 in this normative standard describes the minimum ventilation requirements for gas cabinet of a gas pressure regulating stations. During HyDelta 1.0 and 2.0, [1, 2] , a range of experiments were carried out to gain insight into the ventilation properties of the gas cabinets in the case of hydrogen distribution. Representative gas cabinets used by the Dutch gas network operators were selected, whereby a 1/2m³ cabinet and a 4m³ cabinet station were tested at various leak rates for both natural gas and hydrogen. The selected leak rates partly overlap in size between the different HyDelta programs. During these studies, it was demonstrated that improving the ventilation concept is desirable when using hydrogen. The ventilation capabilities of an existing cabinet can be improved by increasing the ventilation openings area. This results in a lower equilibrium concentration for the same leakage, which can be successfully applied for an application with ydrogen. Thiss also the reason why increasing ventilation is mentioned in this report as a "quick win".
