The Clean Ammonia Pipeline Safety study assesses the necessary design and safety aspects for the long- distance pipeline transportation of large volumes of ammonia through rural as well as densely populated areas. On the basis of the ISPT Roadmap such a pipeline would be assumed to transport some 7 million tonnes per annum (mtpa) equivalent to roughly 1 mtpa hydrogen. For the sake of this study, a 550 km pipeline was considered, which is in line with the projected Delta Rhine Corridor from the Netherlands to Germany. The information generated by the project can nevertheless be applied to other pipeline routs and countries. The scope comprises a pipeline system with a single pipeline, booster pump stations, valve stations and interfaces to importing and receiving terminals.
