Abstract

Natural gas pipeline cost data collected by the Oil and Gas Journal (O&GJ) [ for interstate pipelinesconstructed from 1980 through 2017 were used to develop capital cost estimating equations that are afunction of pipeline diameter, length, and U.S. region. Equations were developed for material, labor,miscellaneous, and right-of-way costs, the four cost components in the O&GJ data, for six different regionsof the United States (U.S.). Each equation is a function of pipeline diameter and length.Adjustment mechanisms were then developed for converting the natural gas pipeline equations intoequations for estimating the costs of hydrogen pipelines. These adjustments were based in part on ananalysis completed by the National Institute for Standards and Technology (NIST) [2, . The results of thiswork were used to update cost models in the Hydrogen Delivery Scenario Analysis Model (HDSAM) [,developed by Argonne National Laboratory for the U.S. Department of Energys Hydrogen Program. Ouranalysis shows a wide range of pipeline cost across different U.S. regions, especially with respect to laborand right-of-way costs. The developed cost formulas for hydrogen pipelines are both important and timelyas hydrogen is being considered as a zero-carbon energy carrier with the potential to decarbonize allenergy sectors, and the cost of hydrogen transportation is essential for techno-economic analysis of itspotential use in these sectors.
