Macro-system model: A federated object model for cross-cutting analysis of hydrogen production, delivery, consumption and associated emissions

The introduction of hydrogen as an energy carrier for light-duty vehicles involves concomitant technological progress in several directions, such as production, delivery, consumption and related emissions. To analyze each of these, a suite of corresponding models have been developed by the DOE, involving inputs from several national laboratories. The macro-system model is being developed as a cross-cutting analysis tool which combines a set of hydrogen technology analysis models. Within the macro-system model (MSM), federated simulation framework is used for consistent data transfer between the component models. The framework is built to suit cross-model as well as cross-platform data exchange and will involve features of `over-the-net´ computation.
