Chevron and National Renewable Energy Laboratory to collaborate on research to produce transportation fuels using algae
Chevron Corporation and the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) announced that they have entered into a collaborative research and development agreement to study and advance technology to produce liquid transportation fuels using algae.
Chevron and NREL scientists will collaborate to identify and develop algae strains that can be economically harvested and processed into finished transportation fuels such as jet fuel. Chevron Technology Ventures, a division of Chevron U.S.A. Inc., will fund the initiative.
The research project announced is the second under a five-year strategic biofuels research alliance between Chevron and NREL announced in October 2006. The first involves bio-oil reforming, a process by which bio-oils derived from the decomposition of biological feedstocks are then converted into hydrogen and biofuels.

Biofuels will play an increasingly important role in diversifying energy supplies to meet the world's growing energy needs, says Don Paul, vice president and chief technology officer, Chevron Corporation. Chevron believes that nonfood feedstock sources such as algae and cellulose hold the greatest promise to grow the biofuels industry to large scale. Collaboration between industry, universities, research institutions and government is essential to overcoming the technological and commercial challenges of manufacturing high-quality transportation fuels from unconventional feedstocks.
Chevron is not alone in re-launching algae research. Several companies have announced 'major breakthroughs', but apparently none have really materialised. Algae are promising, but much more research is needed to identify suitable growing techniques. One of the biggest challenges is to find a compromise between, on the one hand, growing in photobioreactors, in which algae can be controlled and kept stable - but such reactors were deemed too expensive during the Aquatic Species Program - and, on the other, the much less expensive technique of growing algae in open ponds, which presents the problem of algae contamination and competition with other strains.
Biopact recently conducted an interview with a nano-biotechnologist who studied algae-to-biofuels proposals in depth and who has been skeptical of the recent 'breakthroughs' (earlier post). Algae may offer opportunities over the long term, but a considerable amount of new research is required. It is interesting to see that the NREL is taking back up this research, which it started in the 1970s, and is doing so in collaboration with a major oil company that has said 'oil is plenty'.

NREL operated the Aquatic Species Program for the Department of Energy for nearly 20 years, giving us unique insights into the research required to produce cost-effective fuels from algal oils or lipids. Our scientists have the advanced tools and the experience to rapidly increase the yield and productivity of key species of algae. In Chevron we have found an ideal research partner with the skills and knowledge to transform these algal lipids to cost-competitive fuels and to distribute those fuels to consumers. - Dan Arvizu, NREL DirectorAlgae are considered a promising potential feedstock for next-generation biofuels because certain species contain high amounts of oil, which could be extracted, processed and refined into transportation fuels using currently available technology. Other benefits of algae as a potential feedstock are their abundance and fast growth rates. Key technical challenges include identifying the strains with the highest oil content and growth rates and developing cost-effective growing and harvesting methods (earlier post):
