美国Algenol生物燃料公司（AlgenolBiofuels）   
Algenol生物燃料公司的燃料转化技术用二氧化碳、阳光、海水等提取乙醇,基本过程是是用二氧化碳和农场动物废弃物培养水藻，水藻在进行光合作用时利用阳光把养分和二氧化碳转化为乙醇燃料。陶氏化学、美国国家可再生能源实验室、佐治亚理工学院、以及美国的一家薄膜科技研究公司为这一工程提供一系列的技术支持。通过上述机构的合作，乙醇生产会有突破性进展。
Algenol Biofuels Inc. is introducing its DIRECT TO ETHANOL™ technology.

• Algenol Biofuels is an innovative algae to ethanol company.

• Algenol has the most advanced 3rd generation biofuels technology producing ethanol from algae through a process powered by the sun.

• Algenol’s technology produces industrial-scale, low-cost ethanol using algae, sunlight, CO2, and seawater.

• Algenol does not use food, farmland, or fresh water.

• Algenol will produce ethanol at a rate of over 6,000 gallons per acre per year.

• The Direct to EthanolTM process links photosynthesis with the natural enzymes to produce ethanol inside each tiny algae cell.

• The Direct to EthanolTM technology is the only end-to-end commercial process that stabilizes and reduces CO2 levels. Algenol puts CO2 to work.
