PIPELINE TRANSPORTATION OF HYDROGEN.

Abstract

An analytical model encompassing characteristics and costs of high pressure pipeline transport of gaseous and liquid fuels has been developed. The model, which minimizes capital investment costs for a specified energy flow rate, was used to compare the transport costs of hydrogen, ammonia, oxygen, and natural gas. It is found that pipeline transmission of a given amount of energy as hydrogen costs 30-50 percent more than for natural gas. Other siting and design factors, however, suggest that total transport costs for the two fuels may be more nearly equal. The cost of cooling hydrogen for transport is greater than the saving in pipeline cost.
