Hydrogen Delivery System – How to Distribute Hydrogen Energy from Productions to End Stations
An important element for the entire infrastructure of hydrogen energy infrastructure is having hydrogen delivery system the safely and efficiently deliver hydrogen from productions sites to end stations. Hydrogen delivery methods are varying widely, most of them depend on the hydrogen production method and end use. Currently, hydrogen is transferred to a limited number of production plants by using pipeline or transported by road via cylinders, tube trailers. A small percentage of hydrogen transport is by using ship or by rail car.
Treatment for the pipelines must be provided as an effective tool for the needs of effective supply and demands. But nowadays, hydrogen pipelines are limited into some areas of the United States, where hydrogen refineries are concentrated and major chemical plants are concentrated. This area we can find in California, Indiana, Texas and Louisiana. Pipelines are now owned by government; instead it is the property by commercial producers of hydrogen operation. State government should gave licenses to install and maintain such pipelines.
Another method of hydrogen distribution via high pressure cylinders and tube trailers, commonly apply to the extend range of 100-200 miles from production sites till facilities or distribution. More than that, they need another way of transport by using liquid form super-insulated, cryogenic, over-the-road tankers, railcars and barges, and then evaporated for use in customer premises. This is to accommodate the length of up to 1000 miles between production sites into distribution area.
The delivery of hydrogen can be qualified by the parties as follows: The national supply network will be transformed from fossil fuels based infrastructure (oil and gas) into part that will accommodate centralized and decentralized energy productions facilities. In the future, it is expected that pipelines will deliver hydrogen into high demand areas, and truck and rail will distribute hydrogen demand in rural and other low. On-plant is hydrogen distribution facilities constructed, where demand is high enough to maintain the technologies supported.
An economic energy development strategy for the transition to a hydrogen supply is needed. This is because since energy based economy is depending of volume and fast of hydrogen delivery system. There is no easy balancing between the amount of investment required to reduce costs, and the gradual development of market reach. Life cycle cost is not applicable to other solutions delivery. Any strategy for selecting the best and easy appropriate distribution system should include the complete life cycle cost of the options. This lets in the full social costs of choices.
The technology to deliver and distribute hydrogen costs more than conventional fuel delivery. This high cost in hydrogen delivery methods could lead to the use of conventional fuels and the provision of related infrastructure at the point and the transition to small hydrogen systems on the ground. However, there is currently no efficient ways to produce hydrogen in small systems.
Customers require the same level of comfort, price, performance and security in the administration of hydrogen fuel cells to the administration of conventional fuels. Current solutions to hydrogen refueling projects are not mature enough to provide these facilities. Codes and standards are developed. Today is the lack of regulations and standards for the delivery of hydrogen and the lack of harmonization between national and international codes.
An infrastructure of hydrogen distribution will be launched in many regions of the United States. Government-sponsored pilot tests of fuel at the retail level will be the basis for certification of data units of natural gas fuel. The total cost analysis of alternative delivery must be done. The analysis should examine options for addressing the sites of potential costs of maintaining the storage infrastructure and the adequacy of existing infrastructure for the future of hydrogen.
