NREL Invites Proposals for Hydrogen Project Funding

Up to $6 million in U.S. DOE Fuel Cell Technologies Office (FCTO) funding is available for collaborative Hydrogen at Scale (H2@Scale) research and development projects. The goal is to address key challenges associated with wide-scale production and use of hydrogen to address critical issues such as enabling grid resiliency, energy security, domestic job creation, and leadership in innovation. Proposals are due September 15, 2017 at 5 p.m. MDT.

What Do Consumers Prefer? Data Offers Insight on Vehicle Choices

How much does the average consumer know or care about new vehicle technologies? What factors make some buyers willing to consider an alternative fuel vehicle? What challenges still exist for broader consumer acceptance? NREL's new Transportation-Related Consumer Preference Data publications and data repository provide answers to these questions, offering unique access to findings on public attitudes about topics such as the importance of fuel economy and plug-in electric vehicles.

Data Mining Guides Fuel Cell and Hydrogen Technologies R&D

NREL's National Fuel Cell Technology Evaluation Center (NFCTEC) provides secure management, storage, processing, and visualization of industry proprietary data. Over the last 10 years, NREL has collected and analyzed driving and fueling data from 227 fuel cell electric vehicles traveling more than 7 million miles, and recently began collecting data from 26 new retail hydrogen fueling stations in California. NFCTEC engineers mine large quantities of complex data to track progress and guide future research and development of technologies including fuel cell electric vehicles, hydrogen fueling stations, and fuel cell buses.

Millions of Miles in Real-World Travel Data Inform Planning, Modeling, and Analysis

NREL's Transportation Secure Data Center (TSDC), a centralized repository of detailed data from travel surveys and studies, features second-by-second GPS data for millions of miles of travel. The TSDC's two-level access approach facilitates data availability for legitimate research while maintaining the anonymity of survey participants. The data can be combined with demographic, economic, traffic volume, road grade, vehicle fuel economy, weather, and land-use reference information to support a variety of transportation analyses. Subscribe to the TSDC newsletter for periodic updates.

11.5M Miles of Data and Advanced Analytics Accelerate Commercial Vehicle R&D

NREL's Fleet DNA commercial vehicle data repository recently surpassed 11.5 million miles of high-resolution data from 1,700 medium- and heavy-duty vehicles operated by fleet partners across the country. Fleet DNA helps industry partners accelerate the development of advanced vehicle technologies across a broad range of commercial vehicles, vocations, and weight classes. NREL researchers combine Fleet DNA with other data sources using multi-variate data analysis, data fusion, and visualization techniques—such as principal component analysis and hierarchical clustering—to investigate complex, multi-dimensional transportation issues and solutions.

Manufacturers Use Duty-Cycle Analyses to Optimize Vehicle Designs

Leveraging Fleet DNA data to characterize real-world duty cycles for urban delivery vehicles, NREL has segmented in-use driving profiles into operational modes and developed representative drive cycles using the Drive-Cycle Rapid Investigation, Visualization, and Evaluation (DRIVE) tool. Industry partners Cummins and Robert Bosch are using these drive cycles in their development of commercially viable, range-extended electric vehicles for urban delivery applications, targeting efficiency improvements of 50%. Industry, government, and research partners are also using such representative drive cycles for powertrain development and design optimization.

Analysis Provides Insight into Hydrogen Sustainability, Market Viability

NREL uses an integrated suite of modeling and analysis capabilities to examine national hydrogen infrastructure roll-out scenarios, assess regional hydrogen sustainability and resource availability, and perform financial analyses of hydrogen stations. NREL's Scenario Evaluation and Regionalization Analysis (SERA) model integrates detailed geographic data, hydrogen infrastructure and supply chain costs, sustainability metrics, and financial analyses within an optimization framework. The Hydrogen Financial Analysis Scenario Tool (H2FAST) provides in-depth financial analysis of hydrogen fueling stations.
