DOE to issue incubator funding opportunity to help advance bioenergy development; algal biofuels a main focus

June 19, 2015

The US Department of Energy’s Office of Energy Efficiency and Renewable Energy (DOE EERE) intends (DE-FOA-0001343) to issue, on behalf of the Bioenergy Technologies Office (BETO), a funding opportunity announcement (DE-FOA-0001320) targeting innovative technologies and solutions to help advance bioenergy development. DOE anticipates posting the FOA in or around July 2015.

The incubator opportunity is intended to fund projects that will pursue research and development (R&D) not significantly represented in BETO’s current portfolio, as a way to support and explore innovative new approaches for integration into the Office’s future program plans. The FOA will seek to support projects that facilitate BETO’s goals in Algal Biofuels R&D; Feedstocks Supply and Logistics R&D; and Conversion Technologies R&D.

Audi partner Joule announces its “CO2-recycled” ethanol meets US and Euro specs; $40M financing

May 11, 2015

Joule, the developer of a direct, single-step, continuous process for the production of solar hydrocarbon fuels using engineered cyanobacteria (earlier post), announced the successful results from third-party testing of its ethanol fuel (Sunflow-E), setting the stage to obtain certification for commercial use.

Initiated by Audi, Joule’s strategic partner in the automotive space (earlier post), the test results confirm that Joule’s ethanol meets: American Society for Testing and Materials (ASTM) D4806 – Denatured fuel ethanol for blending with gasolines for use as automotive spark-ignition engine fuel; and German Institute for Standardization (DIN) EN 15376 – Ethanol as a blending component for petrol.

Rice study shows algae monocultures for biofuel stably grown in open reactors fed by municipal wastewater

April 03, 2015

Results of a 14-week study by Rice University researchers suggest that algae monocultures for biofuel feedstock can be grown in open tank bioreactors using municipal wastewater as a nutrient source. The stable productivity of monocultures suggests that this may be a viable production method to procure algal biomass for biofuel production.

In an open access paper published in the journal Algae, the researchers reported that they easily grew high-value strains of oil-rich algae while simultaneously removing more than 90% of nitrates and more than 50% of phosphorous from municipal wastewater. Co-author Meenakshi Bhattacharjee said the use of wastewater is one of the most promising solutions for eliminating the algae industry’s dependence on chemical fertilizers.

DOE BETO awards $10M to 7 advanced biofuels projects

February 21, 2015

The US Department of Energy’s (DOE) Bioenergy Technologies Office (BETO) has selected seven projects to receive up to $10 million to support innovative technologies and solutions to help advance the development of advanced biofuels, including bugaboo and drop-in hydrocarbons.

The Bioenergy Technologies Office is working to produce cost-competitive ($3/gallon of gasoline equivalent) advanced biofuels from non-food biomass resources that reduce greenhouse gas emissions by 50% or more versus petroleum-based alternatives. These newly selected projects are intended to support this effort.

Researchers devise method to produce jet-range hydrocarbons as co-product of production of algal biodiesel; role of alkenones

Researchers from Western Washington University and Woods Hole Oceanographic Institution have developed a method to produce jet-fuel range hydrocarbons as a co-product of the production of algal biodiesel from the biomass of the industrially grown marine microalgae Isochrysis. A paper on their work is published in the ACS journal Energy & Fuels.

Certain species of algae—including Isochrysis—synthesize a unique class of lipids: long-chain (35-40 carbons) alkenones. The structure of alkenones is characterized by a very long liner carbon chain with trans double bonds and a methyl or ethyl ketone. The researchers developed a method for the isolation of pure alkenones from Isochrysis biomass in parallel with biodiesel production.

EPA approves Algenol ethanol as RFS advanced biofuel with D5 code; 69% reduction in GHG compared to gasoline

January 13, 2015

The US Environmental Protection Agency (EPA) has approved ethanol made from Algenol’s process as an advanced biofuel, meeting the Greenhouse Gas (GHG) reduction requirements under the Renewable Fuels Standard (RFS). Algenol’s ethanol, produced by photosynthetic cyanobacteria, is now eligible for a Renewable Identification Number (RIN) under the D5 classification. (Earlier post.)

As part of this approval, the EPA determined that ethanol produced from the Algenol Direct to Ethanol (DTE) process resulted in an approximate 69% reduction in greenhouse gases when compared to gasoline.

DOE will award up to $25M to reduce costs of algal biofuels to less than $5/gge by 2019

September 30, 2014

The US Department of Energy (DOE) announced up to $25 million in funding to reduce the cost of algal biofuels to less than $5 per gasoline gallon equivalent (gge) by 2019. (Earlier post.)

The release of the new funding opportunity announcement (DE-FOA-0001162) occurred on the first full program day for the Algae Biomass Summit in San Diego, at which algae entrepreneurs, researchers, investors, producers and end-users are gathering to share developments, as well as to explore the ongoing challenges of technology, financing and commercialization. DOE Assistant Secretary EERE David Danielson, the opening keynote speaker for the summit, said that the agency is “all in” on algae fuels.

DOE to award up to $25M in funding for work on cost-effective algal biofuels

September 23, 2014

The US Department of Energy (DOE) will award up to $25 million in funding to support the development of cost-effective algal biofuels. (Earlier post.) The Targeted Algal Biofuels and Bioproducts (TABB) FOA (DE-FOA-0001162) seeks the development of alternative pathways to overcome two of the key barriers to commercializing algal biofuels: the high cost of producing algal biomass and the low yield of target biofuel and bioproduct feedstocks produced from algae.

The goal is to improve DOE’s Bioenergy Technologies Office’s (BETO) 2019 projected cost of algal biofuels from mature technology of about $8 per gallon gasoline gallon equivalent (gge) to less than $5 gge through creation of valuable products alongside fuels and achieving increased biomass productivity that leads to higher feedstock yields.

DOE to issue funding solicitation for algal biofuels and bioproducts; targeting <$5 gge by 2019

August 20, 2014

The US Department of Energy’s (DOE) Office of Energy Efficiency and Renewable Energy (EERE) intends to issue, on behalf of the DOE Bioenergy Technologies Office (BETO), a Funding Opportunity Announcement (FOA) (DE-FOA-0001162) entitled “Targeted Algal Biofuels and Bioproducts (TABB)”. The TABB FOA seeks to reduce the cost of algal biofuels.

BETO’s 2019 projected state of technology (SOT) for the cost of algal biofuels is modeled at about $8 per gallon gasoline gallon equivalent (gge) based on a lipid extraction pathway without valuable co-products. The TABB FOA will support work at bench and process development scales to develop valuable co-products, crop protection, and CO2 utilization strategies. BETO expects the TABB FOA to result in modeled mature algal biofuel costs of less than $5 gge by 2019.

Joule first to gain US EPA clearance for commercial use of modified cyanobacteria for fuel production

July 01, 2014

The US Environmental Protection Agency (EPA) has favorably reviewed Joule’s Microbial Commercial Activity Notice (MCAN) for the company’s first commercial ethanol-producing catalyst (a modified Synechococcus cyanobacterium). This clears the catalyst for commercial use at the company’s demonstration plant in Hobbs, New Mexico.

This also marks the first time that EPA has allowed the commercial use of a modified cyanobacterium (although not of other modified microorganisms such as S. cerevisiae, E. coli, T. reesei, etc.). (The full list of EPA notifications under the Toxic Substances Control Act—TSCA—is available here.)
