Permafuels, Inc. is a Chapel Hill, NC based company that has received a grant(s) from the Department of Energy's SBIR/STTR program. The abstract(s) for these grant award(s) are provided as well since they provide insights into Permafuels, Inc.'s business and areas of expertise. Although biodiesel production using supercritical alcohols is an extremely fast and clean method, it has not been economically competitive with conventional catalytic approaches. This project will optimize the supercritical process to enable cost-effective commercial production of biodiesel fuel.

American Biodiesel, dba Community Fuels, is an advanced biofuel producer. The company produces among the highest quality biomass-based diesel fuels available - which qualifies as an Advanced Biofuel through the Environmental Protection Agency (EPA), and its own fuel standard closely mirrors the requirements of multiple major oil companies and exceeds the Federal fuel standard (ASTM Standard).

EnerTech Environmental is a renewable energy company operating in the environmental protection and waste management sectors. The company's main services include the development and commercialization of clean combustion technologies for biosolids and other organic wastes, which are converted into high-grade renewable fuel. EnerTech primarily serves the renewable energy industry. It was founded in 1992 and is based in Wichita, Kansas.

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.

Aerophase, Inc. is a Longmont, CO based company that has received a grant(s) from the Department of Energy's SBIR/STTR program. The abstract(s) for these grant award(s) are provided as well since they provide insights into Aerophase, Inc.'s business and areas of expertise. 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.

ZeroPoint Clean Technology is a company focused on renewable energy, specifically in the biomass power plant sector. The company's main service involves the construction of 2-12MW biomass power plants using leading biomass gasification technology, which converts woody biomass into high-quality synthesis gas and a stable form of sequestered carbon, known as biochar. This synthesis gas can replace oil or gas in engines, burners, and boilers, or be used to produce chemicals and liquid fuels. It was founded in 2006 and is based in Potsdam, New York.
