The first Hartmann wellhead for hydrogen well testing phase 1 was recently installed in the Netherlands. Our customer Gasunie is responsible to develop the national hydrogen infrastructure. Within the project, sustainable hydrogen will be stored at the Zuidwending underground gas storage facility.
First, the existing wellhead equipment was comprehensively tested by Hartmann´s Material Suitability Test in order to prevent material fatigue and hydrogen embrittlement. In addition to the existing hydrogen suitable parts (green spool) Hartmann designed and manufactured new wellhead components including metal-to-metal sealing, API 6A ball valves. As part of the FAT a successful H2 test for leak-tightness was conducted at Hartmann. Simultaneously, Hartmann is currently processing wellhead orders for Gasunie H2 testing phase 2 as well as for the first German hydrogen projects.
