The document outlines a long list of potential hydrogen chains that could be considered for modeling in 2020. It includes 28 potential chains organized into two parts - part 1 focuses on renewable feedstocks like wind, solar, wave, geothermal, and biomass, while part 2 focuses on fossil fuel feedstocks like natural gas. The chains describe the hydrogen production method, transportation/distribution options, and end uses. The goal is to reduce this long list of 28 potential chains down to a shorter list of 10 or fewer for further analysis and modeling of their estimated impacts in 2020.

Feedstock Transport
• Hydrogen chains:
– Simplified description of various ways of producing,
transporting and using hydrogen
– A key input for all the modelling work
• Potentially vast number of possibilities (18
technologies gives 1,028,160 potential
arrangements)
• Need to reduce to a more manageable size!
• Reduce a long list (28) to a short list (max 10)
