In particular, the webinar examined the challenges and existing guidance for selecting structural materials for hydrogen service. Speakers from DOE's Sandia National Laboratories reviewed the "Technical Reference for Hydrogen Compatibility of Materials," an important tool for identifying promising materials for hydrogen service and summarizing hydrogen compatibility data, as well as discovering gaps in available materials data and standards for qualifying materials for hydrogen service.
DOE Analysis Related to H2USA
July 24, 2013
EERE staff and Fuel Cell Technologies Office-funded researchers provided an informational briefing on models, tools, and various analyses relevant to H2USA, a new public-private partnership focused on advancing hydrogen infrastructure to support more transportation energy options for U.S. consumers, including fuel cell electric vehicles. The new partnership brings together automakers, government agencies, gas suppliers, and the hydrogen and fuel cell industries to coordinate research and identify cost-effective solutions to deploy infrastructure that can deliver affordable, clean hydrogen fuel in the United States.
Guidance for Filling Out a Detailed H2A Production Case Study
July 9, 2013
EERE has developed a series of publicly-available techno-economic modeling tools for evaluating the environmental impacts and costs of hydrogen delivered to fuel cell electric vehicles (FCEVs). This webinar addressed one of these models in detail, the H2A (Hydrogen Analysis) model. H2A allows a user to estimate the cost of producing hydrogen from a variety of different technical pathways and feedstock resources and can be used to compare the relative advantages of various production technologies for cost-effective and environmentally friendly hydrogen production. In addition, H2A analysis of individual pathways can identify primary cost drivers, the projected high cost of hydrogen based on the current technology status, and the key remaining research and development challenges to meeting cost and performance goals for hydrogen production. The webinar included information on the H2A model concept and structure, types of input data required, and methods for running the model. Results of analysis, which include the levelized cost of hydrogen, identification of the major cost contributors, and sensitivity analysis were also featured. An example case study of hydrogen production from electrolysis of water was presented to illustrate the H2A process.
Hydrogen Storage Materials Requirements
June 25, 2013
The Hydrogen Storage Engineering Center of Excellence has been modeling and developing onboard hydrogen storage systems and components utilizing materials based storage media to meet the Energy Department's technical targets for storage systems. This webinar addressed the critical materials requirements needed for both adsorbents and chemical hydrogen carriers to meet the 2017 DOE technical targets.
Automotive and MHE Fuel Cell System Cost Analysis
April 16, 2013
Battelle Memorial Institute and Strategic Analysis, Inc. gave an overview of automotive and material handling equipment (MHE) fuel cell system cost analyses. Strategic Analysis presented an overview of Design for Manufacturing and Assembly (DFMA) techniques and outlined the basic steps and guiding principles of DFMA cost analysis, showed how it can be used to refine system design and select manufacturing process, and how it can be beneficially applied to both early-stage, conceptual concepts as well as late-stage, fully-defined systems. For MHE applications, Battelle described the cost analysis approach; the design of the system, design assumptions, and manufacturing processes modeled using the DFMA software; costs of the system, sub-system, and specific components; the main cost drivers identified through a sensitivity analysis; and a summary of opportunities for cost reduction.
Testing Oxygen Reduction Reaction Activity with the Rotating Disc Electrode Technique
March 12, 2013
This webinar highlighted the use of the rotating disc electrode (RDE) technique to measure oxygen reduction reaction (ORR) activity in fuel cell applications. A review of recent literature shows that the determination of the ORR activity has numerous intricacies that have not been systemically cataloged, resulting in values for the mass activity of Pt/C that vary significantly. Next steps will be to establish standard procedures and measurement parameters for the RDE technique so that novel catalysts can be benchmarked for ORR activity versus an accepted Pt/C baseline for polymer electrolyte fuel cell applications. The webinar addressed these issues, and introduced a tentative set of testing parameters to allow for RDE experiments to result in reproducible ORR activity and durability values.
Hydrogen Refueling Protocols
February 22, 2013
More than 200 hydrogen refueling stations are projected to be constructed across the United States, Japan, and Germany in the next few years. Automobile Original Equipment Manufacturers (OEMs) have developed fueling protocols that incorporate critical information related to their vehicles such as fuel temperature and pressure, initial vehicle pressure, and initial state of charge of the vehicle. These protocols allow for a fast and safe fill at the station and complies with the storage system operating limits. However, a single, performance-based protocol is needed to standardize the market and allow for a safe fueling of all vehicles. In March of 2010, SAE International published the Technical Information Report (TIR) guideline, SAE TIR J2601, to standardize hydrogen refueling protocols. This webinar presented the current refueling methods including the TIR guideline, SAE TIR J2601. The TIR guideline was developed using OEM hydrogen storage systems and third-party laboratory testing. The guideline establishes a table-based approach which allows all OEMs to safely fuel vehicles within a few minutes. The fueling protocol has now gone through two years of field trials, being used in hydrogen fueling demonstration projects in the United States, Europe, and Asia.
