Researchers from the University of Cambridge, in association with Boeing, have successfully tested a light aircraft powered by a parallel hybrid-electric propulsion system, in which an electric motor and gasoline engine work together to drive the propeller. The demonstrator aircraft—based on a single-seat, ultralight Song motor glider—uses up to 30% less fuel than a comparable plane with a gasoline-only engine. The aircraft is also able to recharge its batteries in flight, the first time this has been achieved.
The hybrid system was designed and built by engineers at Cambridge with Boeing funding support. The hybrid aircraft uses a combination of a ~7 kW Honda 4-stroke piston engine and a 10 kW electric motor/generator, coupled through the same drive pulley to spin the propeller. The hybrid system delivers approximately the same power as the standard engine for the Song—a 15 kW Bailey V5 single-cylinder 4-stroke.
Boeing conducts world’s first flight with 15% blend of NExBTL renewable diesel as aviation biofuel
December 04, 2014
Boeing has completed the world’s first flight using “green diesel,” a renewable, drop-in hydrocarbon biofuel that is widely available and used in ground transportation. The company powered its ecoDemonstrator 787 flight test airplane with a blend of 15% NExBTL renewable diesel from Neste Oil and 85% petroleum jet fuel in the left engine. (Neste Oil can also produce a NExBTL synthetic paraffinic kerosene as a discrete, and already approved, commercial aviation fuel.)
Boeing previously found that renewable diesel is chemically similar to HEFA (hydro-processed esters and fatty acids) aviation biofuel approved in 2011. With a renewable diesel production capacity of 800 million gallons (3 billion liters) in the US, Europe and Asia, the on-road fuel could rapidly supply as much as 1% of global jet fuel demand. With a wholesale cost of about $3 per gallon, inclusive of US government incentives, green diesel approaches price parity with petroleum jet fuel.

Brazilian researchers evaluating the lifecycle GHG emissions of a renewable jet fuel produced from sugar cane in Brazil using Amyris’ proprietary technology platform (earlier post) found that the farnesane-based renewable fuel presents “a substantial potential” to mitigate the GHG emissions of the aviation sector. Their paper is published in the ACS journal Environmental Science & Technology.
In their base case, the researchers calculated a “rather optimistic” GHG footprint of 8.5g CO2eq/MJ; lifecycle emissions of fossil jet fuel usually lie within the 80−95g CO2eq/MJ range. However, they noted, the estimation is highly uncertain, with a number of factors—especially related to electricity exports, sugar cane farming itself, and agrochemicals production and use—significantly affect the outcome. The results of the Monte Carlo analysis indicate life cycle emissions of 21 ± 11 g CO2eq/MJ (mean ± SD), with substantial influence from the LUC factor.
Researchers develop JP-8 enzymatic biofuel cell; electricity from alkanes under mild conditions
November 05, 2014
|Representative schematic of hardware employed for testing of a complete biofuel cell. Credit: ACS, Ulyanova et al. Click to enlarge.|
A team from the University of Utah and CFD Research Corporation (CFDRC) reports the first bioelectrocatalysis of alkanes to produce electricity. In an paper published in the journal ACS Catalysis, they describe the use of a two-enzyme cascade in an enzymatic biofuel cell to oxidize hexane, octane and then JP-8, a jet fuel (C6-C16) comprising a mixture of alkanes.
An enzymatic biofuel cell contains many of the same components as a hydrogen/oxygen fuel cell—i.e., anode, cathode, and separator. However, instead of metallic electrocatalysts at the anode and the cathode, the enzymatic biofuel cell uses enzymes as the catalysts. The enzyme cascade reported in this new work is efficient, sulfur-tolerant, and produces power densities up to 3 mW/cm2 in a JP-8 enzymatic biofuel cell at room temperature without preprocessing of the fuel—as opposed to traditional metal catalysts which require fuel pre-processing. This output is comparable to high power density sugar and alcohol biofuel cells, the researchers said.
Neste Oil de-emphasizing microbial oil R&D for renewable diesel; seeking other uses for cellulosic biomass
October 07, 2014
Neste Oil, the producer of NExBTL renewable diesel, is realigning its long-term R&D and switching from an emphasis on research into the production of microbial oil as a feedstock for NExBTL renewable diesel and renewable jet fuel (earlier post) to other areas of technology for using cellulosic forestry and agricultural waste, due in part to feedstock cost issues.
Despite the decision to de-emphasize microbial oil, Neste Oil emphasized that cellulosic waste will continue to play an important role in its research strategy, adding that it remains committed to its goal of further extending its feedstock base and making greater use of waste and residues in this area in particular.
Southwest Airlines signs purchase agreement with Red Rock Biofuels for renewable jet fuel from forest residues; ~3M gallons per year
September 24, 2014
Southwest Airlines has signed an agreement with Red Rock Biofuels LLC (RRB) to purchase low carbon renewable jet fuel, made using forest residues that will help reduce the risk of destructive wildfires in the Western United States. The airline’s agreement with RRB covers the purchase of approximately three million gallons per year. The blended product will be used at Southwest’s Bay Area operations with first delivery expected in 2016.
RRB’s first plant will convert approximately 140,000 dry tons of woody biomass feedstock into at least 12 million gallons per year of renewable jet, diesel, and naphtha fuels. The company recently received a $70-million grant under phase 2 of the US Defense Production Act Title III Advanced Drop-in Biofuels project for construction of the facility, which will also produce mil-spec fuels. (Earlier post.)
California Energy Commission awards $5M grant to AltAir Fuels to expand renewable diesel production; $3M to GFP Ethanol for sorghum feedstock

The California Energy Commission approved $8 million in grants to two biofuel companies stemming from a solicitation issued earlier this year (PON-13-609: Pilot-Scale and Commercial-Scale Advanced Biofuels Production Facilities).
AltAir Fuels LLC (earlier post) will receive $5 million to expand production of renewable diesel fuels at its Paramount facility in Los Angeles County from 30 million gallons per year to 40 million gallons per year, and allow for processing of additional feedstocks. This facility will also co-produce renewable jet at commercial scale and a byproduct chemical and gasoline component. GFP Ethanol is receiving $3 million to support the development of sorghum as a feedstock for lower carbon intensity ethanol.
USDA closes on $105M loan guarantee to Fulcrum for biorefinery converting municipal waste to renewable jet fuel; first USDA loan for biojet
September 04, 2014
The US Department of Agriculture (USDA) has closed on a $105-million Biorefinery Assistance Program loan guarantee through Bank of America, N.A. to Fulcrum Sierra Biofuels, LLC to build a biorefinery to produce jet fuel from municipal solid waste (MSW) via a proprietary two-stage thermochemical process. (Earlier post.)
USDA Rural Development’s loan guarantee represents less than half of the $266 million project cost. The plant is expected to produce 11 million gallons of fuel annually. This is the first loan guarantee USDA has made for the production of bio jet fuel.
Cathay Pacific Airways makes strategic equity investment in Fulcrum BioEnergy; MSW to biojet; 375M gallon supply agreement
August 08, 2014
Cathay Pacific Airways has made a strategic equity investment in Fulcrum BioEnergy—a pioneer in the development and commercialization of converting municipal solid waste (MSW) into sustainable aviation fuel (earlier post)—as part of the airline’s biofuel strategy and to help it achieve a target of carbon-neutral growth from 2020. Cathay Pacific, which also has an option for further investment, is the first airline investor in the sustainable biofuel developer.
Cathay Pacific has also negotiated a long-term supply agreement with Fulcrum for an initial 375 million gallons US of sustainable aviation fuel over 10 years (representing on an annual basis approximately 2% of the airline’s current fuel consumption) that meets all the airline’s technical requirements and specifications.
Boeing partners with South African Airways to convert Solaris energy tobacco into jet fuel
August 07, 2014
|Solaris energy tobacco is optimized for seed production for energy applications, not leaf production. Click to enlarge.|
Boeing, South African Airways (SAA) and SkyNRG are collaborating to make sustainable aviation biofuel from Solaris, a new hybrid tobacco plant optimized for seed production for energy applications. This initiative broadens cooperation between Boeing and SAA to develop renewable jet fuel in ways that support South Africa’s goals for public health as well as economic and rural development.
Solaris is a new, non-GMO, high-seed tobacco variety protected by patents, the rights to which are held by Sunchem Holdings in Italy, which is partnering with US-based Tyton BioEnergy Systems on its testing and deployment. Solaris maximizes the production of flowers and seeds to the detriment of the leaves production, and biomass for biogas production. The plant is extremely robust, and is able to grow in various climates and soils. One hectare of Solaris can deliver an average seed yield of 4 to 10 tonnes with multiple harvests per year (depending on climate conditions). The seed contains around 40% oil.
Continental Motors introduces new diesel V-6 aviation engine
August 02, 2014
|The new CD-300 engine made its debut in Oshkosh. Click to enlarge.|
Continental Motors introduced the CD-300, its new V-6 diesel engine, at EAA AirVenture in Oshkosh this week. The CD-300 was flown for the first time in July at Continental’s German development center in Altenburg onboard an Cirrus airframe. The company said that the flying test-bed exhibited rates of climb and cruise performance that exceeded engineer’s expectations.
The CD-300 features common rail technology, direct injection, turbo charging, liquid cooling, and an advanced reduction gear system. Like the smaller CD-100 engine, the CD-300 is based on a Mercedes-Benz automotive core adapted for aviation use. In interviews at AirVenture, Continental Motors president Rhett Ross suggested that the company would begin to deviate from focusing on an exclusive automotive-derived approach.
Researchers synthesize diesel- and jet-range cycloalkanes from lignocellulosic platform compounds
July 18, 2014
Researchers at the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, have synthesized, for the first time, a mixture of C9−C15 branched alkanes and cycloalkanes with relatively higher density from 2-Methylfuran (2-MF) and cyclopentanone (CPO)—selective hydrogenation products of furfural, which can be produced in industrial scale with lignocellulose.
Most work done so far with lignocellulose-based platform compounds has concentrated on the production of diesel (C9−C21) or jet fuel (C8−C16) range straight-chain alkanes and/or branched-chain alkanes, the team notes in their paper in the ACS journal Energy & Fuels. Although those alkanes have good thermal stability and excellent combustion efficiency, their lower densities require blending with conventional jet fuel (a mixture of straight-chain alkanes, branched-chain alkanes, and cyclic hydrocarbons) to meet the specifications of aviation fuel.

Click to enlarge.
Under a new 10-year, $1.1-billion agreement, Alcoa will supply key parts for Pratt & Whitney’s jet engines, including the forging for the first aluminum fan blade for jet engines. The forging was developed for Pratt & Whitney’s PurePower engines using an advanced aluminum alloy and a proprietary manufacturing process. Also for the PurePower engines, Alcoa is developing a fan blade forging using its most advanced aluminum-lithium alloy.
Under the $1.1 billion deal, Alcoa will supply components for Pratt & Whitney’s PurePower PW1000G, V2500, GP7000 and several other regional jet and military engines. The unique Geared Turbofan architecture of the PurePower engine allows for aluminum alloys to be used in the Pratt & Whitney designed fan blades, making the engine lighter, as well as more fuel and cost efficient.
Washington State/Boeing SOFC shows promise for aviation and automotive applications
June 17, 2014
|MoO2-based SOFC using a fuel mixture consisting of n-dodecane, CO2 and air. Kwon 2013. Click to enlarge.|
Researchers at Washington State University, with colleagues at Kyung Hee University and Boeing Commercial Airplanes, have been developing liquid hydrocarbon/oxygenated hydrocarbon-fueled solid oxide fuel cells (SOFCs) for aviation (the “more electric” airplane) and other transportation applications, such as in cars. These fuel cells first internally—i.e., no external reformer—reform a complex liquid hydrocarbon fuel into carbon fragments and hydrogen, which are then electrochemically oxidized to produce electrical energy without external fuel processors. The SOFCs feature a MoO2 (molybdenum dioxide) anode with an interconnecting network of pores that exhibit excellent ion- and electron-transfer properties.
In a new paper in the journal Energy Technology, the team reports that this novel fuel cell, when directly fueled with a jet-A fuel surrogate (an n-dodecane fuel mixture), generated an initial maximum power density of 3 W cm-2 at 750 °C and maintained this high initial activity over 24 h with no coking. The addition of 500 ppm of sulfur into the fuel stream did not deactivate the cell.

|The D7566 committee is running a number of task forces on alternative fuels; the use of farnesane is one of those (red outline). Source: CAAFI. Click to enlarge.|
With the release of the newly revised ASTM D7566-14 standard for jet fuel, Amyris and Total have begun to prepare to market a drop-in jet fuel that contains up to 10% blends of renewable farnesane. (Earlier post.)
The revised standard, developed by ASTM Committee on Petroleum Products, Liquid Fuels, and Lubricants, now includes the use of renewable farnesane as a blending component in jet fuels for commercial aviation. This latest version of ASTM D7566, Standard Specification for Aviation Turbine Fuel Containing Synthesized Hydrocarbons, will allow a biomass-based renewable jet fuel, as developed by Amyris and Total, to support the commercial airliners’ goal of reducing greenhouse gas emissions.
Navy fuel solicitation targeting minimum 10% drop-in biofuels component in F-76 and JP-5; at least 39M gallons biofuels
June 11, 2014
The US Navy has posted a Farm-to-Fleet Inland/East/Gulf Coast Solicitation (SP060014R0061) seeking a minimum of about 39 million gallons of drop-in drop-in JP-5 and F-76 biofuels from currently approved pathways—i.e., Hydroprocessed Esters and Fatty Acid (HEFA) or Fischer Tropsch (FT)—for April 2015-March 2016 fuel deliveries.
Under this solicitation, the Navy has a goal that 10% of its total military specification JP-5 aviation turbine fuel and F-76 naval distillate fuel requirements consist of biofuels.

May 29, 2014
|Spatial pattern of PN concentration. Inset shows wind direction. Credit: ACS, Hudda et al. Click to enlarge.|
Results of a new study suggest that emissions particle emissions from airplane traffic at Los Angeles International Airport (LAX) are a major source of particle number (PN) concentrations in the Los Angeles area that are of the same general magnitude as the entire urban freeway network. The results also indicate that the air quality impact areas of major airports may have been seriously underestimated.
The study by a team from the University of Southern California and the University of Washington, published in the ACS journal Environmental Science & Technology, measured the spatial pattern of particle number (PN) concentrations downwind from the Los Angeles International Airport (LAX) with an instrumented vehicle (a gasoline hybrid) that enabled coverage of larger areas than allowed by traditional stationary measurements.
Study finds that optimized integrated catalytic processing of biomass could produce renewable jet fuel with selling price as low as $2.88/gallon
May 09, 2014
|Integrated processing of hardwood to renewable jet and chemicals. Click to enlarge.|
A team from seven US universities and the Korea Institue of Science and Technology, led by George Huber, Professor of Chemical and Biological Engineering at the University of Wisconsin-Madison, has developed an integrated catalytic process for the conversion of whole biomass into drop-in aviation fuels with maximal carbon yields.
The researchers expect that in its current state, the proposed technology could deliver jet fuel-range liquid hydrocarbons for a minimum selling price of $4.75 per gallon—assuming nth commercial plant that produces 38 million gallons liquid fuels per year with a net present value of the 20 year biorefinery set to zero. Future improvements in this technology, including replacing precious metal catalysts by base metal catalysts and improving the recyclability of water streams, could reduce this cost to $2.88 per gallon.
ICCT: US domestic airlines show modest improvement in fuel efficiency since 2010, top performers Alaska and Spirit widen lead
April 30, 2014
The overall fuel efficiency of US airlines on domestic operations improved by 2.3% from 2010 to 2012, less than what is needed to meet US greenhouse gas (GHG) reduction goals, according to an analysis released today by the International Council on Clean Transportation (ICCT).
Alaska Airlines had the most efficient US domestic operations in both 2011 and 2012, the same position it occupied in a 2010 benchmark assessment published by the ICCT last year. (Earlier post.) Spirit Airlines ranked a close second all three years. Alaska and Spirit have widened their lead over other airlines since 2010, the study found, by deploying advanced aircraft and other technologies as well as through more efficient operations practices.

Byogy and Avianca launch initiative to accelerate approval of Alcohol-to-Jet (ATJ) fuel
April 25, 2014
|Byogy’s four-step process for the conversion of ethanol to renewable jet fuel. Click to enlarge.|
Byogy Renewables and airline partner Avianca Brasil (earlier post) have launched an initiative to support advanced testing to accelerate the approval by ASTM of Byogy’s alcohol-to-jet (ATJ) fuel. (Earlier post.) The Avianca/Byogy Team will perform advanced Flight Testing using the CFM-56 powered A319 to acquire test data and support an Environmental Impact Study to drive ASTM adoption of Byogy’s ATJ fuel.
Byogy’s proprietary ATJ process converts ethanol to a full replacement renewable jet fuel that does not require blending, and also demonstrates performance characteristics better than jet fuel produced from oil. Byogy’s jet fuel is not an additive, but instead, a full replacement standalone fuel, and hence can be used at any blend ratio up to 100%, the company says.
Navy researchers produce high-performance renewable fuels by combining heterogeneous catalysis with biosynthesis
April 18, 2014
A team from the Naval Air Warfare Center, Weapons Division (NAWCWD) at China Lake, with colleagues from the National Institute of Standards and Technology (NIST), have demonstrated that renewable high density fuels with net heats of combustion ranging from ~133,000 to 141,000 Btu gal-1—up to 13% higher than commercial jet fuel (~125,000 Btu)—can be generated by combining heterogeneous catalysis with multicyclic sesquiterpenes produced by engineered organisms. A paper on their work is published in the RSC journal Physical Chemistry Chemical Physics.
This advance has the potential to produce a range of higher-density biofuels to improve the range of aircraft, ships, and ground vehicles without altering engine configurations, they suggested.
BA and Solena Fuels to build GreenSky landfill-waste-to-jet-fuel plant in Thurrock; completion in 2017
April 16, 2014
British Airways and its partner Solena Fuels announced that the UK GreenSky facility to convert landfill waste into jet fuel (earlier post) will be built in Thames Enterprise Park, part of the site of the former Coryton oil refinery in Thurrock, Essex. The site has excellent transport links and existing fuel storage facilities. One thousand construction workers will be hired to build the facility which is due to be completed in 2017, creating up to 150 permanent jobs.
The plant will convert approximately 575,000 tonnes of post-recycled waste, normally destined for landfill or incineration into 120,000 tonnes of clean burning liquid fuels using Solena’s Integrated Biomass-Gas to Liquid (IBGTL) technology. British Airways has committed to purchasing, at market competitive prices, the jet fuel produced by the plant for the next 11 years which equates to about $550 million at today’s prices. It is also providing construction capital and becoming a minority share holder in GreenSky.
Neste Oil and DONG Energy partner on renewable diesel and jet fuels from ag residues via microbial oil
February 28, 2014
Neste Oil, the world’s largest producer of premium-quality renewable fuels, is working with DONG Energy, one of the leading energy groups in Northern Europe, to develop an integrated process to produce renewable diesel and aviation fuel derived from agricultural residues.
DONG Energy’s Inbicon technology will be used in the first part of the process to pre-treat biomass and produce cellulosic sugars that can then be converted into microbial oil with Neste Oil’s technology (earlier post). Microbial oil can be used as a feedstock for Neste’s NExBTL process for premium-quality renewable fuels such as renewable diesel and renewable aviation fuel.
Renault introduces ZE-ready concept with drone Flying Companion; targeting new markets
February 05, 2014
|The KWID CONCEPT comes with a Flying Companion drone stored on the roof. Click to enlarge.|
Renault unveiled the KWID CONCEPT at the Delhi Auto Show—the first Renault concept car unveiled outside Europe. The KWID CONCEPT features a “Flying Companion”—a small drone that can be operated in one of two modes. Automatic mode uses a pre-programmed flying sequence and GPS location; manual mode enables the companion to be controlled using a dashboard-integrated tablet.
The Flying Companion is the first of its kind in the automotive world. It takes off from the rotating rear portion of the KWID CONCEPT’s roof. Renault suggests that the Flying Companion could be used for a variety of purposes, including scouting traffic, taking landscape pictures and detecting obstacles on the road ahead.
Boeing, UAE partners make progress with oilseed halophytes as feedstock for renewable jet fuel; desert plants fed by seawater
January 23, 2014
Boeing and research partners in the United Arab Emirates have made breakthroughs in sustainable aviation biofuel development, finding that desert plants fed by seawater (the oilseed-producing halophyte Salicornia bigelovii) can produce biofuel more efficiently than other well-known feedstocks. (Earlier post.) The Sustainable Bioenergy Research Consortium (SBRC), affiliated with the Masdar Institute of Science and Technology in Abu Dhabi, will test these findings in a project that could support biofuel crop production in arid countries, such as the UAE.
S. bigelovii is a leafless, C3, succulent annual salt marsh plant that produces an oilseed on seawater irrigation in coastal desert environments; the oil from the seeds is suitable for biofuel production. Yields on seawater are similar to conventional oilseeds under ideal conditions. SBRC research also found that the entire shrublike plant (i.e., its lignocellulosic biomass as well as the the oil) can be turned into biofuel effectively.
Boeing proposing direct blending of renewable diesel in jet fuel; seeking approval this year
January 16, 2014
Boeing is working with the US Federal Aviation Administration (FAA) and other stakeholders to gain approval for the direct blending of renewable “green” diesel into aviation fuel, thereby further reducing the aviation industry's carbon emissions.
Renewable diesel made using oils and fats is chemically similar to today’s aviation biofuels, according to Boeing analysis. If approved, the fuel would be blended directly with traditional jet fuel. A blend percentage would be established through the testing and review/approvals process, according to Jessica Kowal in Boeing’s Environmental Communications. The company’s internal goal is to see this approved this year.
