The H2A Delivery Components Model focuses on the components required to deliver liquid hydrogen or compressed hydrogen from a central production plant or distributed production unit to the nozzle of the dispenser. The H2A Delivery Scenario Model uses an engineering economics approach to cost estimation. For a given scenario, a set of components (e.g., compressors, tanks, tube trailers, etc.) are specified, sized, and linked into a simulated delivery system or pathway infrastructure. Financial, economic, and technological assumptions are then used to compute the levelized cost of those components and their overall contribution to the delivered cost of hydrogen.

Realistic economic and technology-based assumptions are critical to accurate analytical studies. DOE's H2A Analysis Group develops the building blocks and frameworks needed to conduct rigorous and consistent analyses of a wide range of hydrogen technologies.
