Renewable Filling Station
  • In a joint project with the U.S. Department of Energy, the Las Vegas Valley Water District, and Proton Energy Systems, the Center for Energy Research developed a refueling station for renewable hydrogen that was powered by solar energy.
  • The Center for Energy Research and Proton Energy Systemsworked together to:
  • Develop the requirements for the fueling system
  • Survey potential sites
  • Select a site located at the Las Vegas Valley Water District
  • Devise a site plan
  • Design the fueling system layout
  • Support the site permitting process
  • Analyze the system’s performance
  • Complete the conversion of some vehicles to hydrogen fuel
  • Monitor various experimental performance parameters
  • Initially, a conventional pressure (200 psia) electrolyzer was installed. This was followed by a high pressure (1200 psia) electrolyzer. Both of these systems have the capability of operating totally off solar-generated electricity (photovoltaics), totally fromgrid power, or some combination of both sources. After that, a larger unit was installed during the next phase of the project, driven by grid electricity.
  • Due to curtailment of Federal funding for this type of work, the hydrogen filling station closed, effective July 1, 2010.

Conversion of Vehicles to Hydrogen Fuel See next page

Hydrogen Generation
  • As part of this project, the Center for Energy Research converted of two utility vehicles to hydrogen fuel. 
  • One vehicle -- initially all electric -- was converted to a fuel-cell/electric hybrid vehicle
  • The other vehicle -- which initially used gasoline-fueled Internal combustion -- was converted to use hydrogen as a fuel for its internal combustion engine. The direct-injection method was used to pump hydrogen into the cylinder of the engine.
  • A Ford pickup truck was converted to use hydrogen as a fuel.
  • In addition, work was performed on various methods of hydrogen generation, including:
  • A photo-electrochemical electrolyzer cell to generate hydrogen
  • A single-cell PEM electrolyzerwas developed to improve the performance of individual cells and cell stack by optimizing the fluid dynamics and heat transfer behavior inside the cell.

Modeling Hydrogen-Based Systems

  • The Center for Energy Research develops models of hybrid energy systems that use renewable energy as energy sources -- solar, wind, and hydro-electric power.
  • This hydrogen-based system – which consists of an electrolyzer, storage tank, and fuel cell -- iscan be used for seasonal storage of energy.
  • In addition, short-term storage based on battery and supercapacitors has been studied.
  • In related work, UNLV hosted a workshop on hydrogen safety and related codes and standards.
  • This was followed by a roadmapping exercise to outline approaches to hydrogen development for the state of Nevada.
