DNV, the independent energy expert and assurance provider, has expanded its research laboratory in Singapore with new testing equipment for the safety assessments of H2 transport and storage facilities.
H2 is essential to reach the Paris Agreement climate targets, as the best energy source to decarbonize hard-to-abate sectors such as heavy industry, maritime and large-scale transport. It is also central in supporting the integration of intermittent renewables through the provision of flexible power generation options. As several gas network operators in the APAC region are exploring the opportunity to transport H2 through adapted or repurposed infrastructure, DNV’s new test chamber can be used to evaluate whether existing pipelines can safely transport H2 – either blended with natural gas or in pure form.
DNV is currently providing technical advice and support on the integration of blended H2 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 H2 into South Korea’s gas transmission network.
In technical terms, the new equipment in Singapore provides a H2-ready integrated solution for fatigue crack growth rate (FCGR) testing. The test chamber includes H2 booster systems, safety and H2 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 H2 under different operational and environmental conditions, such as high pressure. Testing is necessary because H2 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 H2 environments are essential parameters to assess the integrity, risk of fracture and remaining life of pipelines and equipment for H2 service.
DNV’s Singapore laboratory has offered materials and structural testing and advisory services – including fatigue and fracture toughness testing of steel and welds for pipelines, pressure vessels and process equipment – for more than three decades in the APAC region, providing assurance to oil and gas companies. DNV is active across the whole H2 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 H2 related services in the APAC region and reinforce DNV’s global position on materials testing recognized from its leading-edge labs in the UK (Spadeadam) and the U.S. (Columbus). Bringing materials testing for H2 to the APAC region enhances DNV’s wider and growing role in supporting the development of future H2 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 H2 economies,” said Brice le Gallo, DNV’s Vice President and Regional Director, Energy Systems for Asia Pacific. “Assurance that H2 transportation and storage is safe and reliable can unlock the scale-up of its use to solve major decarbonization challenges such as reducing piped natural gas use in homes and industry.”
