Pipeline, hydrogen delivery

Gaseous hydrogen delivery pathway via pipelines and tube trailers. (After U.S. Department of Energy Hydrogen, fuel cells and infrastructure technologies program multi-year research, development and demonstration plan, Section 3.2, Hydrogen Delivery, January 21, 2005.)... 

Because of high capital costs and potential HE of steel pipelines for high-pressure hydrogen transport, the investigation of fiber reinforcement or other plastic composites as substitutes for steels is one of the major R D tasks within the DOE hydrogen delivery program. The purpose of the work is to achieve reduction in installation costs, better reliability, and safer operation of hydrogen pipelines. 

Hydrogen delivery infrastructure requires sensors for detecting hydrogen leaks and monitoring pipeline integrity. A brief discussion for each type of sensor technology is given in Sections 10.2.4.1 and 10.2.4.2. 

Compression is an integral aspect of gaseous hydrogen delivery via pipelines. Figure 10.21 illustrates various sizes of compressors to be used in the pipeline [6].

Only one presentation dealt with hydrogen delivery- a review of challenges and recent developments in the field that have been funded by the US DOE. While possibly less glamorous, delivery either by pipeline or vehicle, or alternately delivery of another energy source with subsequent on-site hydrogen-generation is a key link in the hydrogen economy and must be properly developed.

Pipeline Delivery Where long distances are involved, hydrogen delivery by pipeline can be the most efficient means for transporting the fuel, similar to the way petroleum or natural gas is shipped throughout the world. Pipeline delivery of hydrogen can take place by three methods ... 

For intercity/rural markets, again, the costs are a function of hydrogen demand. Note that delivery cost tends to be higher and pipelines tend to be less competitive in this market (Figure 10.5). 

For large quantities of hydrogen, pipeline delivery is cheaper than any other option. Pipelines are characterised by very low operating costs, mainly for compressor power, but high capital costs. The investment for pipelines is in proportion to the delivery distance, while the influence of capacity is lower.
