SERA (Scenario Evaluation, Regionalization & Analysis) is a geospatially and temporally oriented infrastructure analysis model that determines the optimal production and delivery scenarios for hydrogen, given resource availability and technology cost. Given annual H2 demands on a city-by-city basis, forecasts of feedstock costs, and a catalog of available hydrogen production and transportation technologies, the model generates “blueprints” for hydrogen infrastructure build-out that minimize the overall net-present-value of capital, operating, and feedstock costs for infrastructure networks that meet the specified demand profiles. The model represents production facilities and pipelines at the level of individually geolocated components, while it treats truck and rail transportation at an aggregate level. Intra-urban locations of dispensing stations and of hydrogen production for stationary applications are generated using a geospatial statistical model that matches empirical distributions of such facilities.

Prior to October 2009, the model was know as the Hydrogen Deployment System Modeling Environment (HyDS-ME)[1][2][3].
