Hydrogen Infrastructure: Four Low-Pressure Storage Tanks Go Online at Stuttgart’s Green Hydrogen Hub

Over at Stuttgart’s Green Hydrogen Hub in the city port of Wangen they’ve just installed four impressive low-pressure hydrogen storage tanks, making a real mark in the area’s journey toward clean energy. Each of these cylinders towers at about 22 meters, tipping the scales at around 65 tonnes. Together, they offer a whopping 328 m³ of buffer volume, which is about 2,100 kg of green hydrogen. This addition is huge because it helps bridge the gap between the ever-changing nature of renewable energy and the immediate supply needed for transportation, industries, and heating.

The brains behind this project is the local utility company, Stadtwerke Stuttgart, who’s also gearing up to roll out a 9–12 MW stack of PEM electrolysers right there at the same site. Once everything’s up and running, they’re expecting to churn out around 1,000–1,200 tonnes of top-notch green hydrogen each year, and guess what? It’ll all be powered by the utility’s own wind and solar energy! Hydrogen gets moved around through an underground steel pipeline along the regional H2 GeNeSiS corridor, plus they use trailer logistics to deliver it to places within a 50 km radius.
