Citrine Renewable Energy (CRE) develops systems that cost effectively convert the biogas generated by landfills, waste water treatment plants, and other sources of biological waste into high value natural gas, which can be used to power natural gas vehicles. In addition to reducing emissions of greenhouse gases from landfills and sewage works, CRE's systems enable vehicles that use the fuel it produces to reduce harmful NOx emissions by 50 and particulate matter emissions by more than 70. Truck and bus fleets powered by fuel produced by CRE can also benefit from fuel cost savings as compared to the cost of operating diesel engines.

Biodiesel is a key component in US plans to reduce dependence on foreign oil and decrease the environmental impacts of using fossil fuels—but current feedstocks and production technologies prevent it from being cost-competitive. This project will provide enabling technologies for a costeffective, energy-efficient method of producing biodiesel fuels from a variety of lowercost feedstocks. Biodiesel is a key component in U.S. plans to reduce dependence on foreign oil and decrease the environmental impacts of using fossil fuels—but current production technology is not cost-competitive. This project will provide enabling technologies for a cost-effective, energy-efficient method of producing biodiesel fuels.

The amount of energy stored and the efficiency of nickel-metal hydride batteries, such as those used with intermittent renewable energy sources is limited by the use of a liquid electrolyte. This project will develop a solid hydroxide electrolyte suitable for use in high powered batteries. This project will develop a catalyst to cost-effectively transform renewable sources of energy, such as fats and oils to biodiesel. This technology will reduce the United States' dependence on foreign oil and result in a net decrease in carbon dioxide emissions. This project will address the processing of heavy crude and increase limited, large scale refineries. This project will enable the cost effective refining of heavy crude in the Nation's small refineries as well, which are critical to meeting the Nation's liquid fuel supply. This project will develop a new method for harvesting algae containing bio-oils for biofuel production. This process will enable cost-effective production of advanced biofuels such as biodiesel, green diesel, green gasoline, and green jet fuel reducing our nation's dependence on foreign oil. Magnet harvesting of algae offers the prospect of a significant reduction in the cost of harvesting high oil content algae for biofuel use. Combined with algae's high fuel per acre yield, this can increase the availability of cost effective biofuels. This project will identify infrastructure problems and system requirements to design and fabricate an affordable, safe and energy efficient home hydrogen fueling appliance. It is targeted to meet hydrogen refueling needs of the average US traveler on a daily basis and has potential application as backup power source in emergencies. This project will develop technology that will produce aviation fuels from algae-derived biodiesel, which has significant energy density to be used an alternative transportation fuel source. This project aims to develop an innovative biomass preprocessing system to improve overall bioenergy production efficiency by utilizing an environmentally-friendly approach. The broadbased capabilities of this technology will enable it to perform multiple tasks in a single unit of operation. Renewable fuels from biological feedstocks such as ethanol and biodiesel have been recognized as attractive renewable energy sources; however, the inherently high production costs of these fuels have hampered their widespread application. This project will produce highly efficient catalysts for refining of biological feedstocks offers high efficiency and low-cost production. This project will develop a novel diesel fuel reformer which will provide high quality fuel gas to a Solid Oxide Fuel Cell (SOFC) system with high efficiency and low system complexity. The system will enable SOFC Auxiliary Power Units (APUs) in the 1 - 5 kW range to become economically viable.

The project will produce liquid biofuels from wood biomass resources by fast pyrolysis followed by upgrading of the pyrolysis oils. This research will be a key step towards ending global warming, improving national security, and improving rural economies by reducing our dependence on petroleum feedstocks. Declining petroleum resources, combined with increased demand for petroleum by emerging economies, as well as political and environmental concerns about fossil fuels, are causing our society to search for new sources of liquid fuels. This project will develop a method for conversion of biomass into liquid fuels at a small scale called fast pyrolysis—a process whereby biomass is rapidly converted into a liquid biocrude which can be used for fuel oil or upgraded into gasoline and diesel fuels.
