NASA‘s decision to study the effects of aviation biofuel on engine performance is giving a new boost to the scientific efforts of developing new and effective alternative fuels for use in the aviation industry. The testing can help international aircraft makers to know more about aviation alternative fuels and their effectiveness focused on reducing aircraft operational cost in general:
NASA researchers have begun a series of flights using the agency’s DC-8 flying laboratory to study the effects of alternate biofuel on engine performance, emissions and aircraft-generated contrails at altitude. The Alternative Fuel Effects on Contrails and Cruise Emissions (ACCESS) research involves flying the DC-8 as high as 40,000 feet while an instrumented NASA Falcon HU-25 aircraft trails behind at distances ranging from 300 feet to more than 10 miles. ”We believe this study will improve understanding of contrails formation and quantify potential benefits of renewable alternate fuels in terms of aviation’s impact on the environment,” said Ruben Del Rosario, manager of NASA’s Fixed Wing Project. ACCESS flight operations are being staged from NASA’s Dryden Aircraft Operations Facility in Palmdale, Calif., and will take place mostly within restricted airspace over Edwards Air Force Base, Calif. During the flights, the DC-8′s four CFM56 engines will be powered by conventional JP-8 jet fuel, or a 50-50 blend of JP-8 and an alternative fuel of hydroprocessed esters and fatty acids that comes from camelina plants. More than a dozen instruments mounted on the Falcon jet will characterize the soot and gases streaming from the DC-8, monitor the way exhaust plumes change in composition as they mix with air, and investigate the role emissions play in contrail formation. Also, if weather conditions permit, the Falcon jet will trail commercial aircraft flying in the Southern California region, in coordination with air traffic controllers, to survey the exhaust emissions from a safe distance of 10 miles. The flight campaign began Feb. 28 and is expected to take as long as three weeks to complete. ACCESS follows a pair of Alternative Aviation Fuel Experiment studies conducted in 2009 and 2011 in which ground-based instruments measured the DC-8′s exhaust emissions as the aircraft burned alternative fuels while parked on the ramp at the Palmdale facility. A second phase of ACCESS flights is planned for 2014. It will capitalize on lessons learned from the 2013 flights and include a more extensive set of measurements. The ACCESS study is a joint project involving researchers at Dryden, NASA’s Glenn Research Center in Cleveland and NASA’s Langley Research Center in Hampton, Va.
In a decision of equal importance, IATA has called governments to reach an agreement on formulation a global approach aiming at heliping aviation to find innovative solutions and finally manage it carbon emmisions:
Aviation Biofuel: A need for global agreement on market-based measures – Travel Daily News International
The International Air Transport Association (IATA) called for governments to agree on a global approach to market-based measures (MBMs) to help aviation manage the 2% of global manmade carbon emissions for which it is responsible. IATA also stressed the need for governments and industry to align on all four pillars of the aviation industry’s strategy on climate change: investment in new technology, more efficient operations, better infrastructure and positive economic measure or MBMs. The aviation value chain -airlines, airports, air navigation service providers and manufacturers- has agreed to three sequential targets on climate change: a 1.5% average annual improvement in fuel efficiency to 2020, capping emissions with carbon neutral-growth from 2020 (CNG2020), and cutting net emissions in half by 2050 compared to 2005 levels. It is the only global industry to have set such ambitious targets. “A lot of progress has been made on aviation and the environment. The European Union Emissions Trading Scheme (EU ETS) was a roadblock to establishing a global approach to MBMs. With that roadblock removed we are well positioned for a breakthrough on MBMs. Governments are fully focused on the International Civil Aviation Organization (ICAO) to agree upon a global solution at their upcoming Assembly. And the industry is united and working hard to support that by finding an equitable way to share the burden of achieving CNG2020. A lot of hard work lies ahead but we are committed to achieving a positive result,” said Tony Tyler, IATA’s Director General and CEO, speaking at the Greener Skies Conference in Hong Kong. ICAO has identified three options: carbon offsetting, carbon offsetting with a revenue-generating component, and a full global emissions trading scheme. “Whichever option is chosen, the devil will be in the details. And it is critically important to ensure that the agreement preserves fair competition,” said Tyler.
Flying into green skies with aviation biofuel – ABC Online
The so called greening of the skies is the big challenge for aviation. It currently pumps out 2 per cent of global greenhouse gas emissions but it is aiming to be carbon neutral by 2020. Alternative energy experts who have flown in for Victoria’s Avalon Airshow say bio-fuels are the key…
In an effort of developing transatlantic cooperation for promoting the use of alternative biofuels in aviation industry the US and Spain are decided to work together:
FAA signed a declaration of cooperation with the Spanish Aviation Safety and Security Agency last week to promote the development of sustainable alternative aviation fuels in the United States and Spain. Under the agreement, the two countries will exchange information and ideas to collaborate on projects of mutual interest in developing alternative aviation fuels. Deputy Secretary of Transportation John Porcari said the agreement was signed as part of the agency’s NextGen air traffic modernization goals. The two aviation regulatory agencies will focus on sharing information about research and development activities, while looking to share best practices about alternative jet fuel conversion.“Spain also has an ambitious and innovative alternative jet fuels R&D program, the involvement of all the key stakeholders, and the agricultural resources to support aviation biofuel production. This Declaration of Cooperation will enable us to better share and exchange ideas and best practices to attain our goals,” said Porcari.
Finally, the extesive use of aviation biofuel is a one way ticket for aircraft makers, airlines and passengers globally..!
