NETL Releases Techno-Economic Tools To Model Hydrogen Pipeline Transport Costs

NETL has released two innovative cost models designed to calculate the expenses associated with transporting pure hydrogen using new pipelines and natural gas blended with hydrogen through existing natural gas pipelines. These critical tools will help stakeholders involved in the burgeoning hydrogen economy make better-informed decisions that contribute to the nation's decarbonization goals.

For example, these tools could be used by entities involved in hydrogen hub projectsrecently selected by the U.S. Department of Energy (DOE) and funded by the Bipartisan Infrastructure Bill. The hubs will accelerate the commercial-scale deployment of clean hydrogen and help to generate clean, dispatchable power; create a new form of energy storage; and decarbonize heavy industry and transportation.Accurate estimates of transport costs by pipeline could play a critical role in the success of these projects, where connecting hydrogen producers with hydrogen users is a key element of their success.

The Office of Fossil Energy and Carbon Management (FECM)/NETL Hydrogen Pipeline Cost Model (H2_P_COM), is a Microsoft® Excel-based tool that estimates costs for transporting gaseous hydrogen in a new pipeline from a source, such as a hydrogen production facility, to a final destination, which may be a user of the hydrogen or a distribution center where hydrogen in the pipeline is diverted to multiple end users. The user specifies input values, such as the average annual hydrogen mass flow rate, capacity factor, pipeline length, elevation change along the pipeline, the number of compressor stations, years of operations, and several financial variables including the price charged to transport hydrogen. The model generates revenues and costs for the pipeline and calculates the net present value (NPV) for the project where an NPV greater than zero indicates the price charged is high enough to cover all costs including financing costs.

H2_P_COM and its user's manual are available here.

The FECM/NETL Natural Gas with Hydrogen Pipeline Cost Model (NG-H2_P_COM), is a Microsoft® Excel-based tool that estimates the costs of upgrading existing natural gas pipelines so the pipelines can be used to transport natural gas blended with up to 20 to 25% hydrogen. The cost for upgrading an existing natural gas pipeline depends on the condition of the pipeline and the fraction of hydrogen in the natural gas. If the percent of hydrogen in the natural gas is less than 5%, some existing natural gas pipelines can transport the mixture with no upgrades. For mixtures approaching 25%, an existing natural gas pipeline may require all compressors and some pipe segments to be replaced. The user of the model must specify the upgrades needed and the model will calculate the costs of the upgrades and the cost of operating the pipeline.

As part of the development of NG-H2_P_COM, the development team released a document that compared results from NG-H2_P_COM with results from another techno-economic modeling tool developed by the National Renewable Energy Laboratory called BlendPATH. The two models were run with the same or similar inputs and the resulting costs and cash flows were compared. There was reasonable agreement of the results between the two models.

NG-H2_P_COM, its user's manual and the comparative analysis report are available here.

The release of these two tools underscores the continual enhancement of NETL's techno-economic analysis capabilities and will support the development of new supply chains and decarbonization technologies needed for the clean energy transition.
