Future Work

• Define infrastructure scenarios at v

penetration rates 

– Match demand to hydrogen need

area

• Identify costs and potential for stran

– Use population trends to predict 

hydrogen demand will grow rapid

• Draft technical report to DOE July 2
• U.S. demand results indicate that g

policies can influence geographic asurrounding major metropolitan are

• Different areas have different demo

geographic constraints that affect hdemand dispersion

• Geographic demand is critical to inf
