Algenol Biofuels is an algae-to-ethanol company. Its Direct to Ethanol™ technology uses fermentation to convert algae directly from culture, to ethanol. The firm struck a deal with Mexico-based BioFields to grow and process algae. The Dow Chemical Company plans to work with Algenol Biofuels, Inc. to build and operate a pilot-scale algae-based integrated biorefinery that will convert CO2 into ethanol

XL Renewables, Inc. is a renewable energy innovation company focused on the large-scale production of algae biomass and the development of integrated biorefinery projects. XL plans to grow algae on 2,400 acres of adjacent state land, using manure water, carbon dioxide produced as a byproduct of the ethanol process and sunlight

The BioFields is a Mexican company that includes a small power plant, which provides around 2-3 million metric tonne (MT) of CO2, enough for 300 mgpy of ethanol production. The company has collaboration with another company; Algenol Biofuels.The BioFields Mexico facility will have an eventual capacity between 1 and 2 Billion Gallons per year

Inventure Chemical Technology was formed to capitalize on the great opportunity posed by our breakthroughs in algae to biodiesel/ethanol conversion processes. They are applying our patent pending processes to develop and commercialize second generation ethanol and biodiesel technology utilizing a variety of feedstocks, including algae. Their expertise includes both process conversion and plant design/construction. Inventure currently operates a commercial prototype algae biofuel processing facility in Seattle Washington, where it is currently producing biodiesel and ethanol from algae sourced from facilities in Israel, Arizona, and Australia. Inventure's technology will deliver a viable ROI for companies that use algae technology for sequestering CO2.
