Hydrogen Analysis (H2A)
H2A, which stands for Hydrogen Analysis, was initiated to better leverage the combined talents and capabilities of analysts working on hydrogen systems, and to establish a consistent set of financial parameters and methodology for analyses. The development of H2A was based on the need to improve the transparency and consistency of the analysis approach, to improve the understanding of the differences among publicly available analyses, and to seek better validation of such analyses through dialog with industry.
The H2A Analysis models fall into two categories: H2A Production and H2A Delivery. The H2A Production models enable the users to perform economic analysis of forecourt (distributed) and central hydrogen production systems using various energy resources, including renewables, coal, natural gas, and biomass. In coordination with industry participants, a set of economic assumptions/approaches were implemented in the H2A methodology to facilitate consistent and comparable analyses of hydrogen production and delivery technologies. A number of current timeframe case studies were developed using the H2A Production analysis model and can be downloaded from the H2A Production site. Users of the H2A models can develop hydrogen production case studies beginning with a blank model or alter the assumptions to meet their analysis needs.
The H2A Delivery model, also called the H2A Components model, is designed so that the user can rapidly calculate the delivered cost of hydrogen for a particular delivery component. At this stage, the model only performs cost analysis for components included in a delivery infrastructure based on compressed hydrogen gas or liquid hydrogen. Examples of components included in the model include a compressor, a compressed gas refueling station, a liquefier, a liquid hydrogen refueling station, and a geologic storage system. The tabs included in this Excel based model are key inputs to the Hydrogen Delivery Scenario Analysis Model (HDSAM) which is based at Argonne National Laboratory. HDSAM can be used to determine the delivered cost of hydrogen for a variety of compressed hydrogen gas and liquid hydrogen delivery scenarios. These scenarios encompass an entire delivery infrastructure which can be comprised of multiple components.
