Connected Commercial Vehicles—Retrofit Safety Device Kit Project: Final Report
2014Co-Authors: Denny Stephens, Doug Pape, Dave Leblanc, Scott E. Bogard, Roger Berg, Bryan Wells, Gordon PeredoAbstract:Connected vehicle wireless data communications can enable safety applications that may reduce injuries and fatalities. Cooperative vehicle-to-vehicle (V2V) safety applications will be effective only if a high fraction of vehicles are equipped. Deployment of V2V technology will be enabled if it is available not only for manufacturing in new vehicles but also for retrofit to existing vehicles. The objective of the Connected Commercial Vehicles—Retrofit Safety Device (CCV-RSD) Kit Project was to develop complete Hardware and software that can be used in various brands and models of heavy trucks. The RSD kits provide the functionality needed for cooperative V2V and vehicle-to-infrastructure (V2I) safety applications to support the Model Deployment and other U.S. Department of Transportation (USDOT) connected vehicle Projects. This Project included testing and documentation needed for installation, operation, enhancement, and maintenance of the units. These retrofit kits were built so they could be installed in existing class 6, 7, or 8 trucks. The RSD kits achieved a V2V and V2I functionality similar to that of the Connected Commercial Vehicles—Integrated Truck vehicles, where onboard equipment was integrated with newly manufactured truck tractors. This final report summarizes all of the activities and accomplishments of this Project. Hardware and software were developed to adapt safety applications to commercial vehicles. Carefully planned testing on a benchtop and test track provided successful operation in the Safety Pilot Model Deployment.

Transient Analysis of Simultaneous Multivariable Signals on Fuel Cell/Gas Turbine Hybrid to Define Control Strategies for Cathode Parameters and Compressor Stall
ASME 2017 15th International Conference on Fuel Cell Science Engineering and Technology, 2017Co-Authors: Bernardo Restrepo, David TuckerAbstract:Transients in a hybrid system composed of a solid oxide fuel cell (SOFC) and a gas turbine (GT) were evaluated during simultaneous manipulation of system airflow bypasses and turbine electric load. The three airflow bypass valves selected for study were chosen for their potential application in controlling dynamic excursions of the main fuel cell and gas turbine parameters in the system. The objective of this work was to understand the physical behavior by the simultaneous operation of the bypass valves along with the turbine electric load in order to formulate scenarios of control on the key parameters relevant to system failure, specifically from compressor stall and surge. Empirical data was collected using the National Energy Technology Laboratory Hybrid Performance Project Hardware simulation of a SOFC/GT hybrid. Step changes were implemented in all three valves for various open/close valve commands and increase/decrease of the turbine electric load simultaneously. The transient response of process variables was analyzed to determine the potential for mitigating or aggravating compressor stall and surge during load excursions.

Equivalence Ratio Startup Control of a Fuel Cell Turbine Hybrid System
Volume 2: Aircraft Engine; Coal Biomass and Alternative Fuels; Cycle Innovations, 2013Co-Authors: David Tucker, Paolo Pezzini, Larry E. BantaAbstract:Initial startup of a direct-fired fuel cell turbine power system with equivalence ratio control using cathode air bypass valves to minimize thermal shock to the fuel cell was evaluated using the Hybrid Performance (Hyper) Project Hardware-based simulation facility at the U.S. Department of Energy, National Energy Technology Laboratory. The turbine in the system was started with the minimum possible airflow through the fuel cell cathode from a cold condition using two bypass valves to mitigate thermal shock failure in the fuel cell. The limitation of bypass flow was set by air requirements to maintain a combustor equivalence ratio below 0.6 during turbine windup. A 1D distributed fuel cell model operating in real time was used to produce individual cell transient temperature profiles during the course of the turbine start. The results provide insight into the procedural requirements of starting a fully coupled hybrid system.Copyright © 2013 by ASME

Preliminary Experimental Results of Integrated Gasification Fuel Cell Operation Using Hardware Simulation
Journal of Engineering for Gas Turbines and Power, 2012Co-Authors: Alberto Traverso, David Tucker, Comas HaynesAbstract:A newly developed integrated gasification fuel cell (IGFC) hybrid system concept has been tested using the Hybrid Performance (Hyper) Project Hardware-based simulation facility at the U.S. Department of Energy, National Energy Technology Laboratory. The cathode-loop Hardware facility, previously connected to the real-time fuel cell model, was integrated with a real-time model of a gasifier of solid (biomass and fossil) fuel. The fuel cells are operated at the compressor delivery pressure, and they are fueled by an updraft atmospheric gasifier, through the syngas conditioning train for tar removal and syngas compression. The system was brought to steady state; then several perturbations in open loop (variable speed) and closed loop (constant speed) were performed in order to characterize the IGFC behavior. Coupled experiments and computations have shown the feasibility of relatively fast control of the plant as well as a possible mitigation strategy to reduce the thermal stress on the fuel cells as a consequence of load variation and change in gasifier operating conditions. Results also provided an insight into the different features of variable versus constant speed operation of the gas turbine section.

IGFC Response to Initial Fuel Cell Load for Various Syngas Compositions
ASME 2011 9th International Conference on Fuel Cell Science Engineering and Technology, 2011Co-Authors: David Tucker, Dimitri O. Hughes, Comas HaynesAbstract:The system response to an initial electric load of the fuel cell during the startup of a direct-fired fuel cell turbine power system was studied using the Hybrid Performance (Hyper) Project Hardware-based simulation facility at the U.S. Department of Energy, National Energy Technology Laboratory for a range of input fuel compositions. The facility was brought to a steady condition at a temperature deemed adequate to minimize stress on the fuel cell during the initial load transient. A 1D distributed fuel cell model operating in real-time was used to produce individual cell transient temperature profiles during the course of the load change. The process was conducted with humidified hydrogen, and then repeated with various syngas compositions representative of different gasifier technologies. The results provide insight into control strategy requirements for mitigation of expected fuel cell failure modes relevant to available gasifier technology.Copyright © 2011 by ASME
