ABU DHABI 17 January 2019: The Sustainable Bioenergy Research Consortium (SBRC), a non-profit entity established by Masdar Institute and part of Khalifa University of Science and Technology, announced the world’s first commercial flight using locally produced sustainable fuel on an Etihad Airways Boeing 787 powered by GE’s GEnx-1B engines.
The flight from Abu Dhabi to Amsterdam marked a major milestone in the development of a clean, alternative aviation fuel to reduce carbon emissions. The initiative also addresses food security in the UAE through the farming of seafood as a core element in the process.
The SBRC partners have been working together to prove the concept of a comprehensive value chain that is centered around the Seawater Energy and Agriculture System (Seas). This is a synergistic industrial platform that supports the aviation sector, the oil and gas industry, food production and the creation of a new agricultural alternative in the UAE.
Etihad Airways has been at the forefront of aviation biofuel research in the region and this marks the first time that a flight has been operated on fuel derived from plants grown in saltwater.
Tony Douglas, Group Chief Executive Officer Etihad Aviation Group, said: “This is a significant milestone for the UAE and its key industries…. Decarbonisation is important across the aviation industry and, together with our partners, Etihad is proud to be at the forefront of this pioneering new research.”
Salicornia Plants
Sustainable fuel for the flight was derived from oil in Salicornia plants, which were grown on the two-hectare SEAS farm in Masdar City. The SEAS is the world’s first desert ecosystem designed to produce fuel and food in saltwater. Fish and shrimp raised at the facility provide nutrients for the plants as well as contribute to the UAE’s food production.
Using sustainable feedstock to produce the fuel significantly reduces life-cycle carbon dioxide emissions compared to fossil fuel. The biofuel is blended directly with jet fuel and does not require any modifications to aircraft, engines or airport fuelling delivery systems. The unique initiative also bolsters the oil and gas industry by using existing refining infrastructure, with the potential to become an important new option for sustainable aviation fuel in the future.
Adnoc Refining played a fundamental role, providing the expertise and infrastructure to ensure the effective refining of the seed oil to meet stringent jet fuel standards. Adnoc Distribution has also provided an essential element of the project through the blending and delivery of the biofuel to the aircraft.
UOP-Honeywell’s (a founding member of the SBRC) Ecofining technology was used in the refining process of the oil and recognition is also given to Abu Dhabi Vegetable Oil Company (Advoc) for essential assistance in the pre-treatment phases.
160,000 Flights on Biofuel
Approximately 160,000 passenger flights have flown on a blend of sustainable and traditional jet fuel since the first biofuels were certified for commercial use in 2011. Sustainable aviation fuel represents a significant opportunity to help aviation meet its goals to cap the growth of carbon emissions by 2020 and cut levels to half of what they were in 2005 by 2050.
Operated by the SBRC, the SEAS pilot facility became operational in March 2016. Salt-tolerant halophyte plants that thrive in desert conditions and do not require fresh water or arable land to grow are nurtured there. After wastewater from the fish fertilises the plants, it is diverted into a cultivated mangrove forest. This further removes nutrients and provides valuable carbon storage before the naturally filtered and treated effluent is discharged back into the sea.
Over the course of the next few years, the system is expected to scale up to 200 hectares in the move towards full-scale commercial implementation.
