Capturing Carbon Dioxide to Fuel the World The amazing technological and economic progress achieved in the past 100 years has largely been fueled by hydrocarbons. However the sustainability of this progress is now coming into question, both due to the rise in greenhouses gases caused by hydrocarbon combustion and the predicted depletion of fossil hydrocarbon sources. Sequesco's goal is to develop technologies which help enable hydrocarbons to continue fueling human progress, while alleviating the problems of greenhouse gas emissions, growing geological scarcity, and the drawbacks of agriculturally produced biofuels. The company's guiding principle is to use microbes as master chemists in sustainable systems that serve the dual role of sequestering carbon dioxide and producing transportation fuels.

Formed as Malibu Capital Partners, Inc., Altra has been in the business of acquiring and developing a portfolio of renewable energy projects throughout the United States specifically focused on the production and sale of ethanol and biodiesel. Altra aims to become the leading integrated biofuels company in the U.S., employing state-of-the-art manufacturing facilities, processing technologies and customer service disciplines, and positioned as a critical biofuels supplier to petroleum companies and other significant end-users in all key geographic markets.

ZeroPoint Clean Tech deploys biomass solutions to make renewable energy and sequester carbon. ZeroPoint has a modular, multi-feedstock gasification technology built to international code. The ZeroPoint solution is built with OEM components by the world's highest quality manufacturers. Skid mounted equipment is packaged into turnkey plants and delivered with leading engineering, procurement and construction firms.

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. 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.

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.

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.
