Progress
note

The following technical accomplishments were achieved by the partners in the HSECoE during the course of the past year. These accomplishments were the result of intense inter-organizational communication and interfacing through the existing Technology Area Lead organization for the Center. These accomplishments are:

  • Completed Programming of HSSIM (Hydrogen Storage SIMulator) to aid in prediction of impact of technical targets.
  • Completed baseline fuel cell power plant models with physical storage fuel sources.
  • Completed finite element models on metal hydrides and adsorbent system.
  • Completed initial metal hydride hydrogen storage system models with various configurations of pressure vessels, buffer tanks, hybridization schemes, pumps and heat exchangers.
  • Completed initial chemical hydride hydrogen storage system models with various configurations of mass transport mechanisms, spent fuel reservoirs and reactors.
  • Completed initial adsorbent hydrogen storage system models with various configurations of heat exchangers, pressure vessels, buffer tanks and pumps.
  • Completed coupling of Vehicle Modeling, Fuel Cell modeling and Storage System modeling in a MatLab/Comsol/Simulink environment.
  • Identified acceptability criteria and UP/DOWN select methodology for Metal Hydrides, Chemical Hydrides and Adsorbent materials.
  • Completed identification of parametric models to be used for Metal Hydride, Chemical Hydride and Adsorbent system thermal models.
  • Compiled a database for each of the materials to be modeled and identified technical data gaps in the data with plans to fill these gaps.
  • Completed an Acceptability Envelope for metal hydrides to aid in determination of the critical thermochemical characteristics required for storage system consideration.
  • Identified critical technologies for pressure vessels, sensing, insulation, thermal generation and fuel purity required to enable use of various storage system materials.
  • Determined the current system technical target status of metal hydrides based on NaAlH4 and technology gaps (gravimetric density, cycle life, safety and toxicity) needing to be addressed to meet the 2010 and 2015 technical targets.
  • Determined the current system technical target status of chemical hydrides based on solid NH3BH3 and technology gaps (fuel purity, fill time, minimum full flow rate and loss of useable hydrogen) needing to be addressed to meet the 2010 and 2015 technical targets.
  • Determined the current system technical target status of adsorbents based on super activated carbon and technology gaps (volumetric density, minimum delivery pressure and loss of useable hydrogen) needing to be addressed to meet the 2010 and 2015 technical targets.
