NIST: Reducing the High Costs of Hydrogen (Fuel) Pipelines

Great Things from Small Things .. Nanotechnology Innovation

NIST 580303_10152072709285365_1905986131_nThe National Institute of Standards and Technology (NIST) has put firm numbers on the high costs of installing pipelines to transport hydrogen fuel–and also found a way to reduce those costs.

NIST researchers used data from such tests to develop a model for hydrogen effects on pipeline lifetime, to support a federal effort to reduce overall costs of hydrogen fuel. (Image: NIST)
Pipelines to carry hydrogen cost more than other gas pipelines because of the measures required to combat the damage hydrogen does to steel’s mechanical properties over time. NIST researchers calculated that hydrogen-specific steel pipelines can cost as much as 68 percent more than natural gas pipelines, depending on pipe diameter and operating pressure.* By contrast, a widely used cost model** suggests a cost penalty of only about 10 percent.>Samples of pipeline steel instrumented for fatigue testingBut the good…
