U.S. Government Awards DuPont, Partners with Technology Investment Agreement for Macroalgae-to-Biobutanol Research
The U.S. Department of Energy (DOE) Advanced Research Projects Agency-Energy (ARPA-E) has awarded a Technology Investment Agreement to DuPont for the development of a process to convert sugars produced by macroalgae into next-generation biofuels called isobutanol. Bio Architecture Lab (BAL) will be a subrecipient on the program. Under this award, the DOE will fund $8.8 million and DuPont and BAL will cost share the balance of the total award, forming a joint cost share program between DOE and DuPont. Butamax™ Advanced Biofuels LLC, a joint venture between DuPont and BP, will be responsible for commercialization of the resulting technology package.
The macroalgae-to-isobutanol project will establish technology and intellectual property leadership in the use of macroalgae as a low cost, scalable and environmentally sustainable biomass for biofuel production. Efforts will focus on: improving domestic macroalgae aquaculture; converting macroalgae to bio-available sugars; converting those sugars to isobutanol; and economic and environmental optimization of the production process.
More than 60 scientists in Wilmington, Del., and Berkeley, Calif., will work on this research and development program. The macroalgae aquafarming project will be conducted in Southern California.
“Our capabilities in the field of metabolic engineering and advanced industrial biotechnology techniques make this a natural addition to our existing R&D pipeline,” said John Pierce, vice president – DuPont Applied BioSciences – Technology.
“Bio Architecture Lab is the leader in the development of technology to utilize macroalgae as low cost, scalable and sustainable biomass for the production of biofuels,” said Nikesh Parekh, CEO of Bio Architecture Lab. “Our partnership with DuPont and Butamax™ validates our core technology and will help us extend it into the production of isobutanol.”
Butamax™ has a multi-generational program to introduce isobutanol from different feedstocks to the market. Initially, isobutanol will be produced from feedstocks such as corn, wheat, and sugarcane. Subsequently, isobutanol production can be based on cellulosic feedstocks and, eventually, advanced feedstocks such as macroalgae.
“We project macroalgae to biobutanol technology will reduce greenhouse gas emissions significantly compared to petroleum,” said Butamax™ CEO Tim Potter. “Butamax™ is expanding its feedstock flexibility to deliver isobutanol sustainably to achieve ever-cleaner transportation fuels. This evolutionary feedstock approach will enable greater reductions in carbon intensity as sustainable lower carbon feedstocks emerge.”
DuPont and BP were the first to identify the potential of isobutanol as an advanced biofuel. Their partnership was formalized in July 2009 with the creation of the Butamax™ Advanced Biofuels LLC joint venture. ButamaxTM and its parent companies have validated the potential of isobutanol to be a viable opportunity to advance biofuels through fleet testing and examination of the fuel value chain.
Butamax™ will commercialize isobutanol, a fuel that:
- has a higher energy content per gallon than many first generation biofuels;
- does not absorb water and can be transported through the existing oil and gasoline distribution infrastructure;
- can be used in gasoline-powered vehicles without modification at higher volumes than first generation biofuels, enabling greater concentrations of renewables into the transport fuel mix.
Butamax™ Advanced Biofuels is the culmination of the partnership between DuPont and BP and will be the leader in isobutanol technology development and marketing. The synergy between Butamax™ as a fast moving and flexible commercialization enterprise and the considerable experience of DuPont and BP in the areas of advanced biotechnology development, transportation fuel design and marketing will achieve rapid market acceptance of the technology developed under this award.
