Advanced testing of materials for hydrogen now available to APAC energy industries
- New testing equipment expands services to APAC customers looking to transport or store hydrogen
- Lab expansion will support rising demand from APAC customers who are exploring if existing infrastructure can be upgraded to support hydrogen blends or even 100% hydrogen
- Assurance through testing can unlock the scale-up of hydrogen use to solve major decarbonization challenges.
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.
Hydrogen 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 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’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 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 recognized 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.
