Steady-State Hydrogen Models

This project developed a user-friendly model, SSCHISM (Steady State City Hydrogen Infrastructure System Model), that estimates the design, cost and emissions for alternative hydrogen infrastructure pathways (including hydrogen production, delivery and refueling) to meet a specified steady-state demand within individual cities.  We use simplified methods to estimate hydrogen demand and delivery system layout, based on geographic inputs (city population, city radius, distances), market factors (market penetration, refueling station coverage/size) and engineering/economic constraints (regional feedstock and electricity prices). 

The outputs include: lowest cost system pathways (feedstock, conversion technology and delivery mode), delivered hydrogen cost ($/kg), primary energy input and CO₂ emissions. The model will be available for download which will provide a user-friendly, EXCEL-based model that will allow the user to quickly compare a range of hydrogen supply options for a variety of geographic and market conditions.  Also included will be a report which will discuss important findings with regards to the important factors which influence the cost, emissions and energy use of various hydrogen infrastructure options.
