In the United Arab Emirates (UAE), Khalifa University, Etihad Airways, Boeing, ADNOC, Safran, GE and BAUER Resources celebrate a major milestone in developing a comprehensive sustainable aviation fuel value chain based on the salt-tolerant Salicornia plant. The Sustainable Bioenergy Research Consortium (SBRC), a non-profit entity established by Masdar Institute announced the world’s first commercial flight using locally produced biojet fuel on an Etihad Airways Boeing 787.
The Etihad Airways flight from Abu Dhabi, UAE to Amsterdam, the Netherlands, a Boeing 787 powered by GE’s GEnx-1B engines, marked a major milestone in the development of clean, alternative aviation fuel to reduce carbon emissions. The initiative also addresses food security in the UAE through the farming of seafood on desert land as a core element in the Salicornia value chain.
This proof of concept is a ground-breaking development that addresses the challenges of energy, water and food security – three elements that are inextricably linked and which form a nexus, meaning that actions in any one area have an impact in the others. What is particularly exciting about the SEAS is that it is an initiative that supports multiple platforms; aviation, oil and gas and agriculture. It is an important specialised initiative under the aquaculture umbrella, with the UAE recognising that this sector represents one of the best uses of what is the region’s most precious resource and has consequently established its aquaculture sector with an investment of more than AED 100 million to develop hatcheries and fish farms, said HE Mariam bint Mohammed Saeed Hareb Al Mheiri, Minister of State for Food Security,
Desert food and fuel value chain
The Sustainable Bioenergy Research Consortium (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.
The UAE’s visionary leadership is strongly committed to positioning the country as a global hub for innovation and sustainability. In this context, productive cross-disciplinary public-private partnerships are crucial to fuelling research and development efforts and creating game-changing innovations that enable a more sustainable future. Deep decarbonisation of energy-intensive industries has a ripple effect on food security and climate action. Clean, alternative aviation fuels are an innovative and sustainable solution to significantly reducing harmful carbon emissions. The UAE is proud to be a pioneer in this domain, said HE Dr Thani bin Ahmed Al Zeyoudi, Minister of Climate Change and Environment.
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.
This is a significant milestone for the UAE and its key industries. Etihad is fully committed to this project which demonstrates a successful proof of concept that is local, viable, cost-effective and sustainable. 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, said Tony Douglas, Group Chief Executive Officer Etihad Aviation Group.
Sustainable aviation fuel (SAF) 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.
The landmark achievement by the SBRC, part of Masdar Institute at Khalifa University, and partners marks a new beginning for the use of clean fuel for air travel. Khalifa University is proud to be part of the consortium, driving research and innovation, while contributing to creating a sustainable biofuel value chain, supporting the UAE’s strategic objectives in the energy and food sectors. The collaboration partners and Masdar Institute researchers have contributed significantly to achieve this success and we believe the use of biofuel for this commercial flight will make a compelling statement that impacts stakeholders in the aviation, energy and transportation sectors, said Dr Arif Sultan Al Hammadi, Executive Vice-President, Khalifa University of Science and Technology.
Drop-in biojet fuel
Using sustainable feedstock to produce the fuel significantly reduces life-cycle carbon dioxide (CO2) 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 SAF in the future.
ADNOC Refining has 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 Ecofining technology was used in the refining process of the Salicornia oil and recognition is also given to Abu Dhabi Vegetable Oil Company (ADVOC) for essential assistance in the pre-treatment phases.
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 (ha) in the move towards full-scale commercial implementation.
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. SAF represents a significant opportunity to help the aviation sector 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.
Etihad’s flight proves SEAS is a game-changer that can substantially benefit air transport and the world. The research and technology being developed shows significant promise to transform coastal deserts into productive farmland supporting food security and cleaner skies, said Sean Schwinn, Vice President of Strategy and Market Development for Boeing International.
