The Fuel Cell Technologies Office (FCTO) will present a live webinar titled "Thermodynamic and Economic Modeling of Boil-Off Losses in Liquid Hydrogen Handling Processes" on Tuesday, June 26, from 12 to 1 p.m. Eastern Daylight Time (EDT). Hydrogen is delivered in liquid form to a host of end users, including hydrogen fueling stations, glassmaking facilities, electronics fabrication plants, and more. The economics of the pathway are challenged by the vaporization of liquid hydrogen (i.e., “boil-off”), particularly during transfers from liquid tankers to stationary dewars. In this presentation, Lawrence Livermore National Laboratory (LLNL) will present findings from a comprehensive early-stage research and development (R&D) analysis of liquid hydrogen boil-off in a variety of scenarios. Topics include (1) early-stage R&D to develop a thermodynamic model that simulates liquid hydrogen transfers, accounting for real gas equation of states and two-phase behavior, (2) an analysis of current liquid hydrogen handling practices and requirements of U.S. Department of Transportation regulations, (3) collection of data on boil-off rates at a fueling facility at LLNL, and (4) predictions of boil-off losses for given station designs and capacities. The webinar will be recorded and include a 15-minute Q&A portion.
