WORLD FIRST US-AUSTRALIA BIOFUEL FLIGHT TAKES OFF

sustainable aviation
SYDNEY, 29TH JANUARY 2018 

The historic trans-Pacific 15 hour flight will operate with approximately 24,000kg of blended biofuel, saving 18,000kg in carbon emissions.

Qantas will use biofuel processed from Brassica Carinata, a non-food, industrial type of mustard seed, developed by Canadian-based agricultural-technology company, Agrisoma Biosciences (Agrisoma).

The flight is part of the partnership announced in 2017 which will also see the companies work with Australian farmers to grow the country’s first commercial aviation biofuel seed crop by 2020.

Qantas International CEO Alison Webster said it was fitting that the airline’s game-changing Dreamliner 787-9 will showcase the future of sustainable aviation.

“The Qantas Dreamliner marks an exciting new era of innovation and travel. The aircraft is more fuel efficient and generates fewer greenhouse emissions than similarly sized-aircraft and today’s flight will see a further reduction on this route.

“Our partnership with Agrisoma marks a big step in the development of a renewable jetfuel industry in Australia – it is a project we are really proud to be part of as we look at ways to reduce carbon emissions across our operations.”

Across its lifecycle, using Carinata-derived biofuel can reduce carbon emissions by eighty percent compared to traditional jet fuel.

The ten percent biofuel blend used on today’s flight will therefore see a seven percent reduction in emissions on this route compared to normal operations.

Carinita requires no specialised production or processing techniques. It is water efficient and The University of Queensland field trials in Gatton, Queensland, and in Bordertown, South Australia, have demonstrated it should do very well in the Australian climate.

It is sown in either fallow areas where food crops fail or in between regular crop cycles, known as “cover cropping”.  Rotational or break-crops can improve soil quality, reduce erosion for food crops and provide farmers with additional income.

Agrisoma CEO, Steve Fabijanski, said biofuel produced from Carinata provides wide ranging benefits.

“Biojet fuel made from Carinata delivers both oil for biofuel and protein for animal nutrition while also enhancing the soil its grown in.

“We are excited about the potential of the crop in Australia and look forward to working with local farmers and Qantas to develop a clean energy source for the local aviation industry.”

Qantas’ first trans-Pacific biofuel flight was made possible with the support of AltAir Fuels and World Fuel Services.

QF96 will depart LAX on Sunday, 28th January and arrive in Melbourne on 30th January (local time).

Carinata seed

FACTS:

Carinata

  • Carinata produces high quality oil, ideal for aviation biofuel, bio-jet for aircraft and bio-diesel for airport vehicles. It is a ‘drop-in’ crop and requires no specialised production or processing techniques.
  • It is sown in either fallow areas where food crops fail or in between regular crop cycles, known as “cover cropping”. Rotational or break-crops improvessoil quality, reduces erosion for food crops and provides farmers with additional annual income.
  • Carinata-based fuel offers a more than 80 per cent reduction in carbon emissions in comparison to standard petroleum based fuel.[1] (opens in new window)
  • The crushed Carinata seed produces a high-quality, high-protein, non-GMO meal for the Australian livestock, dairy and poultry market.
  • One hectare of Carinata seed yields 2,000 litres of oil, which produces 400 litres of biofuel, 1,400 litres of renewable diesel and 10% renewable by-products.

Other ways Qantas is reducing carbon emissions across its operations

  • The 787 uses up to 20 per cent less fuel than other traditional aircraft of its size. Over the next two years Qantas’ Dreamliners will be replacing some of the the older 747 aircraft in its fleet.
  • Across its network, Qantas is creating more efficient flight paths based on factors such as forecast winds and employs Dynamic Airborne Reroute Procedures (DARP) which allows for multiple inflight adjustments to the flight path based on updated meteorological conditions.
  • Qantas Pilots are using a world first flight data application, FlightPulse, which provides industry leading access to the efficiency of their flights and helps them fly more efficiently.
  • In 2007, we introduced the Qantas Future Planet program, which, together with our passengers, has offset more than 3.0 million tonnes of carbon emissions, making the Qantas carbon offset program the world’s largest airline offset program.

Electric VTOL Aircraft

AirSpaceX Reveals Electric VTOL Aircraft at North American International Auto Show in Detroit


NEWS PROVIDED BY

Detroit Aircraft Corp.


DETROIT, Jan. 15, 2018 /PRNewswire/ — NAIAS 2018 – Airspace Experience Technologies, LLC (AirSpaceX), a subsidiary of Detroit Aircraft Corp. (DAC), today revealed a sub-scale model of its autonomous, electric VTOL aircraft, “MOBi-ONE,” at the North American International Auto Show (NAIAS) in Detroit.  MOBi-ONE is designed to autonomously takeoff like a helicopter, fly like a plane, and transport passengers or cargo between urban centers, suburbs, and airports within 60 miles. MOBi-ONE will fly at a top speed of 250 MPH leveraging existing Electric Vehicle (EV) architecture and autonomous technologies.

Recent advances in electric propulsion, automation, and lightweight materials now make the development of this new class of aircraft possible. “MOBi-ONE will offer clean, quiet, and connected on-demand air mobility to the mass traveling public at an affordable price,” says Jon Rimanelli, founder and CEO of Detroit Aircraft and AirSpaceX. “Our vision is to mass produce aircraft leveraging lean automotive design and mass production techniques so our vehicles are affordable to the mass traveling public.”

“Our goal is to deploy 2,500 aircraft at the nation’s 50 largest cities by 2026, targeting existing infrastructure at first,” says JP Yorro, Chief Commercial Officer at AirSpaceX.  “The MOBi development program will be capital intensive, but air Mobility as a Service could generate billions for the economy.  We are considering a broad array of financing options, including potential fractional ownership interest and profit sharing models.*

Last year, U.S. drivers wasted an aggregate $300 billion in fuel and productivity sitting in traffic jams, yielding 38 billion pounds of carbon emissions. Not only is traffic taking over our lives, it is harming our environment. “There is an urgent need for innovation in urban mobility, and I believe on-demand air mobility will go a long way toward reducing pressure on roads while improving the quality of life for commuters on the ground,” says Rimanelli.

MOBi-ONE was designed and built by Detroit Aircraft Corp. at Detroit City Airport.  AirSpaceX teamed with Camilo Pardo, renowned as the chief designer of the 2005 and 2006 Ford GT, in MOBi-ONE’s design.  Pardo and Rimanelli began working together in 2011, prototyping and developing several VTOL concepts over the years. “The evolution of these prototypes culminated in an iconic design with the MOBi-ONE.  We wanted to create an aircraft with a unique appearance that stands alone and also reflects its function,” explained Pardo.

Upon completion of engineering packages, a full-scale aircraft will be manufactured, undergo Part 27 Certification, and be operated by AirSpaceX. The sub-scale MOBi-ONE was taken from clean sheet design, fabrication and assembly in 4 weeks for display from January 14-21 at Cobo Center in downtown Detroit in the AutoMobili-D Technology Showcase.

decarbonizingaviation.com: Neste’s New Online Hub about Sustainable Aviation

Most passengers would be willing to pay a fee for moresustainable aviation

Keilaranta, December 21, 2017: Aviation is the fastest growing means of transport. In 2016, 3.8 billion people travelled by air, and according to the International Air Transport Association (IATA), the number of passengers is predicted to reach 7.2 billion (!) by 2035. With this growth comes the reality that carbon dioxide (CO2)emissions from aviation will grow substantially. Carbon neutral growth in aviation is possible, but requires that airports, solutions providers, airlines, authorities, local community and passengers all unite and contribute to more sustainable travelling.

According to a recent survey, 67% of US passengers, and 53% of European travelers, are concerned about the environmental impacts of air travel. The survey found that over 50% of passengers consider it important that their airline goes above and beyond regulations to be environmentally friendly. Furthermore, the survey found that most passengers are willing to pay a fee for Renewable Jet Fuel, and that this may even positively impact airline and airport preference.

“As aviation currently makes up roughly 2% of the world’s carbon dioxide emissions, making the transition towards carbon neutral growth is an absolute imperative,” says Paul Paoletta, Head of Neste Aviation Solutions.
To raise awareness and facilitate dialog in reducing the aviation industry’s carbon footprint, Neste has opened its decarbonizingaviation.com online hub for all stakeholders in aviation.  The site features videos, blogs, articles and news across hot topics in the decarbonization of aviation debate, from waste materials as sustainable jet fuel for aircraft to changing legislation to passenger perspectives.

“People are travelling more than ever, and the aviation industry is growing. It is crucial that this growth happens responsibly. Neste is working relentlessly to help airports and all aviation stakeholders to take advantage of sustainable low-carbon fuels in their operations. Besides sustainable low-carbon fuels, we are opening other opportunities for more sustainable aviation solutions through our Neste Green Hub solution. Decarbonizingaviation.com is an online platform for all aviation stakeholders who are working for the goal of carbon neutral growth in aviation,” continues Paoletta.

Neste is the world’s largest producer of renewable fuels from waste and residues alongside being the leading producer of renewable diesel, with an annual production volume of 2.6 million tons. By eliminating bottlenecks, this total capacity will be increased to 3 million tons by 2020. Renewable jet fuel is one of Neste’s growth areas. Neste has set a target that the proportion of the company’s renewable products sales outside the road traffic fuels increases to 20% by 2020.

Airbus, Rolls-Royce, and Siemens Team up for Electric Future

Partnership launches E-Fan X hybrid-electric flight demonstrator

 
London,  November 28,  2017: Airbus, Rolls-Royce, and Siemens have formed a partnership which aims at developing a near-term flight demonstrator which will be a significant step forward in hybrid-electric propulsion for commercial aircraft.
The three companies together announced the groundbreaking collaboration, bringing together some of the world’s foremost experts in electrical and propulsion technologies, at the Royal Aeronautical Society in London.  
The E-Fan X hybrid-electric technology demonstrator is anticipated to fly in 2020 following a comprehensive ground test campaign, provisionally on a BAe 146 flying testbed, with one of the aircraft’s four gas turbine engines replaced by a two megawatt electric motor. Provisions will be made to replace a second gas turbine with an electric motor once system maturity has been proven. 
“The E-Fan X is an important next step in our goal of making electric flight a reality in the foreseeable future. The lessons we learned from a long history of electric flight demonstrators, starting with the Cri-Cri, including the e-Genius, E-Star, and culminating most recently with the E-Fan 1.2, as well as the fruits of the E-Aircraft Systems House collaboration with Siemens, will pave the way to a hybrid single-aisle commercial aircraft that is safe, efficient, and cost-effective,” said Paul Eremenko, Airbus’ Chief Technology Officer. “We see hybrid-electric propulsion as a compelling technology for the future of aviation.”
 The E-Fan X demonstrator will explore the challenges of high-power propulsion systems, such as thermal effects, electric thrust management, altitude and dynamic effects on electric systems and electromagnetic compatibility issues. The objective is to push and mature the technology, performance, safety and reliability enabling quick progress on the hybrid electric technology. The program also aims at establishing the requirements for future certification of electrically powered aircraft while training a new generation of designers and engineers to bring hybrid-electric commercial aircraft one step closer to reality.
As part of the E-Fan X program, Airbus, Rolls-Royce, and Siemens will each contribute with their extensive experience and know-how in their respective fields of expertise:
ð       Airbus will be responsible for overall integration as well as the control architecture of the hybrid-electric propulsion system and batteries, and its integration with flight controls.
ð       Rolls-Royce will be responsible for the turbo-shaft engine, two megawatt generator, and power electronics. Along with Airbus, Rolls-Royce will also work on the fan adaptation to the existing nacelle and the Siemens electric motor.
ð       Siemens will deliver the two megawatt electric motors and their power electronic control unit, as well as the inverter, DC/DC converter, and power distribution system. This comes on top of the E-Aircraft Systems House collaboration between Airbus and Siemens, launched in 2016, which aims at development and maturation of various electric propulsion system components and their terrestrial demonstration across various power classes.
Paul Stein, Rolls-Royce, Chief Technology Officer, said: “The E-Fan X enables us to build on our wealth of electrical expertise to revolutionize flight and welcome in the third generation of aviation. This is an exciting time for us as this technological advancement will result in Rolls-Royce creating the world’s most powerful flying generator.
 “Siemens has been driving innovation in core technology fields at full speed,” said Roland Busch, Chief Technology Officer of Siemens. “In April 2016 we opened a new chapter in electric-mobility with the collaboration with Airbus. Building up electric propulsion for aircraft, we are creating new perspectives for our company and also for our customers and society. With the E-Fan X partnership, we now take the next step to demonstrate the technology in the air.”
Among the top challenges for today’s aviation sector is to move towards a means of transport with improved environmental performance, that is more efficient and less reliant on fossil fuels. The partners are committed to meeting the EU technical environmental goals of the European Commission’s Flightpath 2050 Vision for Aviation (reduction of CO2 by 60%, reduction of NOx by 90% and noise reduction by 75%). These cannot be achieved with the technologies existing today. Therefore, Airbus, Rolls-Royce and Siemens are investing in and focusing research work in different technology areas including electrification. Electric and hybrid-electric propulsion are seen today as among the most promising technologies for addressing these challenges.

Airline excited about the continued progress in the renewable fuels

Keilaranta, November 13, 2017: Neste, the world’s leading producer of renewable diesel, and American Airlines, the world’s largest airline, have entered into an agreement to explore opportunities to further reduce American’s environmental footprint through the use of Neste’s renewable fuels. One goal of the cooperation will be complementary efforts to facilitate acceptance and commercialization of High Freeze Point HEFA (HFP-HEFA) renewable jet fuel which is currently under consideration for approval by ASTM International, a globally recognized leader in the development and delivery of voluntary consensus standards for a range of industries.
“Together, Neste and American Airlines are evaluating in-flight and on-the-ground opportunities for mutually beneficial cooperation and collaboration,” says Kaisa Hietala, Neste’s Executive Vice President of Renewable Products. “We share a common view that innovative low-carbon solutions are needed to help the aviation industry meet its greenhouse gas emission reduction goals, and renewable jet fuel is an important part of the solution.”
 “We are excited about the continued progress in the renewable fuels industry,” said Steve Johnson, American’s Executive Vice President of Corporate Affairs, who announced the cooperation between Neste and American Airlines at the Airports Going Green conference this week in Dallas. “We believe commercially viable renewable fuels have the potential to play an important role in helping American further reduce emissions beyond our significant investment in fuel efficient aircraft.”
The aviation industry has set ambitious targets to mitigate greenhouse gas emissions from air transportation, including carbon-neutral growth from 2020 and beyond, and a 50 percent reduction of net aviation CO2 emissions by 2050. Currently, sustainable renewable jet fuel offers the only viable alternative to fossil liquid fuels for powering commercial aircraft.
American Airlines has already taken significant steps to reduce its carbon footprint with an unprecedented fleet renewal program. By the end of 2017, American will have invested more than $18 billion and introduced 496 new aircraft into its fleet since the merger, while retiring 469 older aircraft – giving American the youngest fleet of the U.S. network carriers.

Fast-forwarding to the future of on-demand, urban air transportation

Imagine traveling from San Francisco’s Marina to work in downtown San Jose — a drive that would normally occupy the better part of two hours — in only 15 minutes. What if you could save nearly four hours round-trip between São Paulo’s city center and the suburbs in Campinas? Or imagine reducing your 90-plus minute stop-and-go commute from Gurgaon to your office in central New Delhi to a mere six minutes.

Every day, millions of hours are wasted on the road worldwide. Last year, the average San Francisco resident spent 230 hours commuting between work and home—that’s half a million hours of productivity lost every single day. In Los Angeles and Sydney, residents spend seven whole working weeks each year commuting, two of which are wasted unproductively stuck in gridlock. In many global megacities, the problem is more severe: the average commute in Mumbai exceeds a staggering 90 minutes. For all of us, that’s less time with family, less time at work growing our economies, more money spent on fuel — and a marked increase in our stress levels: a study in the American Journal of Preventative Medicine, for example, found that those who commute more than 10 miles were at increased odds of elevated blood pressure.

On-demand aviation has the potential to radically improve urban mobility, giving people back time lost in their daily commutes. Uber is close to the commute pain that citizens in cities around the world feel. We view helping to solve this problem as core to our mission and our commitment to our rider base. Just as skyscrapers allowed cities to use limited land more efficiently, urban air transportation will use three-dimensional airspace to alleviate transportation congestion on the ground. A network of small, electric aircraft that take off and land vertically (called VTOL aircraft for Vertical Take-off and Landing, and pronounced vee-tol), will enable rapid, reliable transportation between suburbs and cities and, ultimately, within cities.

The development of infrastructure to support an urban VTOL network will likely have significant cost advantages over heavy-infrastructure approaches such as roads, rail, bridges and tunnels. It has been proposed that the repurposed tops of parking garages, existing helipads, and even unused land surrounding highway interchanges could form the basis of an extensive, distributed network of “vertiports” (VTOL hubs with multiple takeoff and landing pads, as well as charging infrastructure) or single-aircraft “vertistops” (a single VTOL pad with minimal infrastructure). As costs for traditional infrastructure options continue to increase[1], the lower cost and increased flexibility provided by these new approaches may provide compelling options for cities and states around the world.

Furthermore, VTOLs do not need to follow fixed routes. Trains, buses, and cars all funnel people from A to B along a limited number of dedicated routes, exposing travelers to serious delays in the event of a single interruption. VTOLs, by contrast, can travel toward their destination independently of any specific path, making route-based congestion less prevalent.

Recently, technology advances have made it practical to build this new class of VTOL aircraft. Over a dozen companies, with as many different design approaches, are passionately working to make VTOLs a reality. The closest equivalent technology in use today is the helicopter, but helicopters are too noisy, inefficient, polluting, and expensive for mass-scale use. VTOL aircraft will make use of electric propulsion so they have zero operational emissions[2] and will likely be quiet enough to operate in cities without disturbing the neighbors. At flying altitude, noise from advanced electric vehicles will be barely audible. Even during take-off and landing, the noise will be comparable to existing background noise. These VTOL designs will also be markedly safer than today’s helicopters because VTOLs will not need to be dependent on any single part to stay airborne and will ultimately use autonomy technology to significantly reduce operator error.

We expect that daily long-distance commutes in heavily congested urban and suburban areas and routes under-served by existing infrastructure will be the first use cases for urban VTOLs. This is due to two factors. First, the amount of time and money saved increases with the trip length, so VTOLs will have greatest appeal for those traveling longer distances and durations. Second, even though building a high density of landing site infrastructure in urban cores (e.g. on rooftops and parking structures) will take some time, a small number of vertiports could absorb a large share of demand from long-distance commuters since the “last mile” ground transportation component will be small relative to the much longer commute distance.

We also believe that in the long-term, VTOLs will be an affordable form of daily transportation for the masses, even less expensive than owning a car. Normally, people think of flying as an expensive and infrequent form of travel, but that is largely due to the low production volume manufacturing of today’s aircraft. Even though small aircraft and helicopters are of similar size, weight, and complexity to a car, they cost about 20 times more.

Ultimately, if VTOLs can serve the on-demand urban transit case well — quiet, fast, clean, efficient, and safe — there is a path to high production volume manufacturing (at least thousands of a specific model type built per year) which will enable VTOLs to achieve a dramatically lower per-vehicle cost. The economics of manufacturing VTOLs will become more akin to automobiles than aircraft. Initially, of course, VTOL vehicles are likely to be very expensive, but because the ridesharing model amortizes the vehicle cost efficiently over paid trips, the high cost should not end up being prohibitive to getting started. And once the ridesharing service commences, a positive feedback loop should ensue that ultimately reduces costs and thus prices for all users, i.e. as the total number of users increases, the utilization of the aircraft increases. Logically, this continues with the pooling of trips to achieve higher load factors, and the lower price feeds back to drive more demand. This increases the volume of aircraft required, which in turn drives manufacturing costs down. Except for the manufacturing learning curve improvements (which aren’t relevant to ridesharing being applied to automobiles), this is very much the pattern exhibited during Uber’s growth in ground transportation, fueled by the transition from the higher-cost UberBLACK product to the lower-cost and therefore more utilized uberX and uberPOOL products.

Gevo: ‘Fly Green Day’ at Chicago O’Hare

Inspiring Airlines to use lower carbon fuels

 
Englewood, Colorado, November 08, 2017: Gevo announced that its alcohol-to-jet fuel (ATJ) derived from renewable isobutanol is being used today by eight commercial airlines for the ‘Fly Green Day’, sponsored by the O’Hare Fuel Committee, at Chicago O’Hare International Airport.  This event is the first time renewable jet fuel has been supplied at Chicago O’Hare using the existing airport fueling infrastructure, such as pipelines, terminals and tankage.
Commercial airlines participating in the ‘Fly Green Day’ are Lufthansa, United Airlines, Etihad, Cathay Pacific Airways, Emirates, Japan Airlines, Korean Air, Atlas Air and FedEx. “This is the first time we have supplied our customers with biojet produced from alcohol and demonstrates how we are working with multiple suppliers to build a leadership position in this area,” said Air BP’s Chief Executive Officer Jon Platt. “We anticipate that through this promotion we will inspire more of our customers to use lower carbon fuels.”
To date, airlines and airports have generally relied on alternative means of supplying renewable jet fuel to the wing, usually trucking jet fuel on site for blending and fueling. For today’s ‘Fly Green Day’, Air BP blended Gevo’s ATJ with regular fossil-based Jet A fuel, certified its quality and then supplied its customers through the airport’s main fuel hydrant system.
 “We are excited to be a part of this project. This is the next stage in development of our goal to reduce greenhouse gas emissions and move forward with the full commercial deployment of renewable jet fuel,” said Thorsten Luft, Vice President Corporate Fuel for Lufthansa AG.
Gevo is a renewable technology, chemical products, and next generation biofuels company focused on the production of isobutanol, as well as related products from renewable feedstocks.
