DENSO building large test facility for production of biofuel from P. ellipsoidea microalgae

August 19, 2015

Japan-based global automotive supplier DENSO Corporation will build a large 20,000 square meter test facility for the culture of Pseudochoricystis ellipsoidea, an oil-producing microalga patented by DENSO. The new facility located in Amakusa, Kumamoto, Japan will be used to perform verification tests needed to establish large-scale microalga cultivation technologies required to improve biofuel production efficiency. The facility will start operations in April, 2016.

DENSO has been working in collaboration with Keio University’s Institute for Advanced Biosciences since April 2008 to produce biofuel extracted from P. ellipsoidea—a fast-growing, vigorous, and easy-to-cultivate microalga, on which DENSO holds patents. Hydrocarbons and triglycerides can be produced photoautotrophically to up to 30% of the dried biomass (Satoh et al.). The hydrocarbon fraction is more than 10 times higher in nitrogen depleted cells.

Proposed process for low-emissions coal-to-liquids

August 05, 2015

The EMS (Earth and Mineral Science) Energy Institute at Penn State has developed a conceptual novel process configuration for producing clean middle-distillate fuels from coal with some algal input with minimal emissions.

The Institute was involved for about 20 years in a project intended to develop a coal-derived jet fuel; a number of papers and reports have already been published on that work. In a new paper in the journal Technology, Professor (Emeritus) Harold Schobert combined a review of the two decades of development with the novel conceptual approach for near-zero emissions coal-to-liquids.

DOE JGI team identify regulators of lipid production in algae; potential boost for algal fuels development

August 04, 2015

Algae naturally produce oils that can be converted into transportation fuels, making this a potentially attractive pathway for large-scale biofuel production. However, high-yield lipid production in algae is a stress response—induced, for example, through conditions such as nutrient deprivation. One of the challenges of optimizing this oil production pathway has been stressing the algae just enough to produce lipids in high yields, but not stressing them enough to kill them.

Now, a team led by scientists from the US Department of Energy Joint Genome Institute (DOE JGI) has analyzed the genes that are being activated during algal lipid production, and in particular the molecular machinery that orchestrates these gene activities inside the cell when it produces lipids. The work, published in a paper in the journal Nature Plants, may help algal bioenergy researchers develop more targeted approaches for producing lipids for fuels.

EPA opens door to consider Carbon Capture and Utilization as part of new Clean Power Plan; algae industry locks on

EPA’s newly released voluminous final Clean Power Plan rule (earlier post) has established the first national standards to limit CO2 emissions from fossil-fuel-fired power plants (Electric Generating Units, EGUs), with a target of a 32% reduction against a 2005 baseline by 2030.

The plan calls for each US state to establish a plan to meet the targeted reductions. Within the text of the final CPP rules, EPA opened up the possibility of allowing “affected EGU (Electric Generating Units) to use qualifying CCU [Carbon Capture and Utilization] technologies to reduce CO2 emissions that are subject to an emission standard, or those that are counted when demonstrating achievement of the CO2 emission performance rates or a state rate-based or mass-based CO2 emission.

DOE awards $18M to six projects for algae-based biofuels; targeting <$5/gge

July 10, 2015

The US Department of Energy (DOE) will award up to $18 million in funding to six projects to reduce the modeled price of algae-based biofuels to less than $5 per gasoline gallon equivalent (gge) by 2019.

Algal biomass can be converted to advanced biofuels that offer promising alternatives to petroleum-based diesel and jet fuels. Additionally, algae can be used to make a range of other valuable bioproducts, such as industrial chemicals, bio-based polymers, and proteins. However, barriers related to algae cultivation, harvesting, and conversion to fuels and products need to be overcome to achieve the Department’s target of $3/gge for advanced algal biofuels by 2030. To accomplish this goal, the Department is investing in applied research and development technologies that can achieve higher yields of targeted bioproducts and biofuels from algae—increasing the overall value for algae biomass.

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.

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.

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.
