The transition challenge for hydrogen
vehicles; analysis of adoption dynamics
Jeroen Struben*)
MIT Sloan School of Management
April 30 2004
*) Many thanks to John Sterman for support and discussions throughout
Agenda
● Context: the Hydrogen transition challenge
● Adoption structure for the vehicle
propulsion platform
● Reduced/partial models analysis
● Insights and future work
Modeling the hydrogen transition challenge - motivation
● Formal model literature on technology adoption
– diffusion (Bass ’69, Rogers ‘62)
– industry evolution
(Abernathy/Utterback ’78,…)
– learning/scale/spillover (…)
– increasing returns and lock-in
(Arthur ’89)
– energy modeling (Farrell ’03)time

Case 2: drivers and familiarity
● Endogenous adoption
● 4th order model
● Competition between entrant (e.g. hydrogen) and incumbent (e.g. ICE)
● Introduce “relative attractiveness”

Conclusions / Insights
● Innovation systems require attention beyond mere acknowledgement of lock-in/dominance/…
● Identify role of particular loops/structures – Here we have modeled and analyzed the more interpretive side
adoption
● Can already identify policies on what prevents/ promotes diffusion– word-of-mouth through non-drivers
– less efficient hybrids could grow faster and takeover (as no infrastructure, spillover issues)
