• Abstract:
  The goal of this project is to add corresponding cryogenic hydrogen infrastructure analysis to a previous study conducted at NREL. Sponsored by the FAA, NREL's study investigated hydrogen implementation at the Seattle, Portland, San Francisco, and Los Angeles airports, primarily focusing on gaseous hydrogen delivery and conducting technoeconomic, emissions, safety, and job analysis. NREL, WSU, and the FAA agreed to this ASCENT project to complement the previous study by evaluating cryogenic hydrogen implementation. As part of this project, contributions were made to the State of the Technology Analysis by reviewing conceptual delivery pathways for liquid hydrogen delivery to airports. Analysis also considered the current, 5-year realistically achievable efficiencies, and limiting efficiencies of liquid hydrogen technologies used in delivery. Delivery scenarios with associated assumptions were developed and modeled for technoeconomic analysis adding to the previous NREL report. The effects of liquid hydrogen storage were evaluated exploring the sensitivity of the levelized cost of hydrogen to boil-off losses and capital costs. Numerical modeling was used to predict boil-off losses and refill frequency for airport hydrogen storage facilities with 6, 12, and 24 metric tonnes per day throughput capacity. Infrastructure spatial estimates were made based on the modeling. Interviews were conducted with three industry collaborators to evaluate specific technological advancements needed to utilize liquid hydrogen at airports.
