Hydrogen delivery system

Defining hydrogen fuel quality specifications is a high priority for the Roadmap. Such specifications must be quantified at the vehicle-station interface and must consider how the presence of small amounts of contaminants affects the performance and durability of fuel cell and balance of plant material compatibility of onboard and stationary hydrogen storage systems and the operation and maintenance of hydrogen production, purification, and delivery systems. Most importantly, fuel quality specification must consider...

Hydrogen can be separated from the flue gas at low cost in high-temperature fuel cells. A SOFC system may be able to cogenerate hydrogen for about 3.00 per kg which can match gasoline. Since these fuel cells could be part of the fueling station, there would be no need for a hydrogen delivery infrastructure. 

The road to hydrogen vehicles and a hydrogen fueling delivery system may take many paths. Today, it may seem unlikely that market forces alone will result in the installation of thousands of hydrogen fueling stations across the country. But, this is exactly what happened with our pres-... 

Figure 15.9 shows the capital investments required for hydrogen infrastructure up to 2030. Onsite SMRs dominate in the early years. After 2025, central production, from biomass and coal, becomes significant, accompanied by pipeline delivery systems and stations. Later on, central production dominates in large cities, although onsite reformers persist in other areas. By 2030, the majority of capital investment is in central plants and pipeline delivery. 

When hydrogen is supplied directly to the fuel cell, as may be the case in transportation systems, the fuel processing section is no more than a storage and delivery system. However, in most...
