• Daily capacity of kg per trailer
• Number of trailers needed to transport a percent of hydrogen demand
• Percent of transport from tube trailers to calculated hydrogen supply from SMR and electrolysis daily; divide by daily capacity of tube truck
Illustrative assumptions for transportation capital investment
SECTOR
Sample Assumptions
H2 Tube Trailers
TRANSMISSION:
• Acts as key link between key production centers and key demand centers
• Distance between major SMR regions, electrolysis regions, and demand centers
• Percent of daily hydrogen demand transported via transmission pipelines
DISTRIBUTION:
• Current proportion of residential and commercial heating to current distribution network
• Percent repurposed for hydrogen distribution based on a percent uplift in portion of residential and commercial buildings heated by hydrogen
Hydrogen Pipeline
Infrastructure
• Injection into the distribution system is primarily through demand center-based electrolyzers
• Injection sites are all demand center-based electrolyzers
• Number of injection points into the distributed gas network
• Capacity of demand center electrolysis
• Percent of the distributed demand center-based electrolyzers will inject into the grid and the remaining percent will fully utilize the produced hydrogen on site
• Number of distribution production sites
• Percent of distributed sites injected into the grid
