The first Hartmann wellhead for hydrogen well test phase 1 was recently installed in the Netherlands. Our customer Gasunie is responsible for the development of the national hydrogen infrastructure. As part of the project, sustainable hydrogen is to be stored in the Zuidwending underground gas storage facility.
Initially, the existing wellhead equipment was comprehensively checked using the Hartmann material suitability test to avoid material fatigue and hydrogen embrittlement. In addition to the existing hydrogen-compatible parts (green gate valve), Hartmann designed and manufactured new wellhead components, including metal-seated API 6A ball valves. As part of the FAT, a successful H2 leak test was carried out at Hartmann. At the same time, Hartmann is currently processing wellhead orders for the Gasunie H2 test phase 2 as well as for the first German hydrogen projects.
