Hydrogen Infrastructure Transitions (HIT)

To analyze the regional Hydrogen Infrastructure transition process, an end-state "static" approach usually assumes a fixed hydrogen demand for a single pathway. The static approach is simple and therefore widely adopted, but has significant limitations for understanding implementation of new fuels. The static approach, with or without optimization, is inaccurate because it ignores the financial effect of evolving factors (such as demand and technologies) on the supplier. The Hydrogen Infrastructure transition problem gets more complicated if we want to consider the spatial details: for example, does the travel behavior and road network layout in the region of interest allow a H2I with very low hydrogen distribution cost?

Hydrogen Infrastructure Transition (HIT) model is a dynamic programming model, which generates the spatial and temporal infrastructure buildup decisions that minimize the net present value of capital and operating costs, carbon externalities, and refueling travel time disbenefits over time. HIT incorporates regionally specific spatial data to find optimal strategies for meeting an exogenously specified market penetration over time. Input assumptions can be varied to study how the optimal strategy depends on technological evolution, feedstock prices, carbon tax, and market penetration rate.
