Advanced testing of materials for Hydrogen now available to APAC energy industries
Apr 25 2023
DNV, the independent energy expert and assurance provider, has expanded its research laboratory in Singapore with new testing equipment for the safety assessments of hydrogen transport and storage facilities.
As several gas network operators in the APAC region are exploring the opportunity to transport hydrogen through adapted or repurposed infrastructure, DNV’s new test chamber can be used to evaluate whether existing pipelines can safely transport hydrogen – either blended with natural gas or in pure form.
DNV is currently providing technical advice and support on the integration of blended hydrogen into gas trunkline assets in India – including transmission pipelines, interconnects and spur lines, compressors, valves, and metering stations and equipment. The company is also assisting Korea Gas Corporation (KOGAS) in a two-year project to assess the viability of blending hydrogen into South Korea’s gas transmission network.
In technical terms, the new equipment in Singapore provides a hydrogen-ready integrated solution for fatigue crack growth rate (FCGR) testing. The test chamber includes hydrogen booster systems, safety and hydrogen alarms, ventilation systems, and an additional test vessel.
DNV’s experts in Singapore will employ the new equipment to assess the fracture, fatigue, and corrosion performance of pipe material such as steel for varying concentrations of hydrogen under different operational and environmental conditions, such as high pressure. Testing is necessary because hydrogen can make steel more brittle and prone to stress cracking. Hence, fracture resistance and fatigue crack growth rates obtained from laboratory testing of the steel and welds in hydrogen environments are essential parameters to assess the integrity, risk of fracture and remaining life of pipelines and equipment for hydrogen service.
DNV is active across the whole hydrogen value chain and has delivered approximately 200 projects globally in the last few years. This new lab facility will substantially support the growing need for hydrogen related services in the APAC region and reinforce DNV’s global position on materials testing recognised from its leading-edge labs in the UK (Spadeadam) and the USA (Columbus). Bringing materials testing for hydrogen to the APAC region enhances DNV’s wider and growing role in supporting the development of future hydrogen value chains and ensuring the safety of facilities through risk advisory, asset integrity and regulatory change.
“This latest investment in our Singapore research and test laboratory offers our APAC customers the advanced testing capabilities energy and other industries are asking for as private and public investment gets behind building local and regional hydrogen economies,” said Brice le Gallo, DNV’s Vice President and Regional Director, Energy Systems for Asia Pacific. “Assurance that hydrogen transportation and storage is safe and reliable can unlock the scale-up of its use to solve major decarbonisation challenges such as reducing piped natural gas use in homes and industry.”
