Achieving Net Zero: Pioneering Energy Efficiency in Aviation with Ann-Sofie Hörlin, Head of Sustainability, SAS
During New York Energy Week 2024, Ann-Sofie Hörlin, Head of Sustainability at SAS, presented an illuminating session on "Achieving Net Zero: Pioneering Energy Efficiency in Aviation." This event, known for gathering the brightest minds to challenge conventional boundaries in energy, technology, and sustainability, provides the perfect platform for Hörlin to share her insights on the future of aviation sustainability.
A Vision for Net Zero in Aviation
Ann-Sofie Hörlin begins her presentation by outlining the aviation industry's ambitious goal to achieve net-zero carbon emissions by 2050. This aspiration is a collective agreement among airlines globally, recognizing their responsibility despite contributing 2-3% of global carbon emissions. Hörlin emphasizes the urgency of this goal, given the expected rise in air travel from developing regions and the broader global decarbonization efforts.
The Four Pillars of Sustainability in Aviation
Hörlin highlights four key areas where the aviation industry must innovate to achieve net-zero emissions:
1. Technology: The focus is on developing advanced engines, new airframes, and revolutionary technologies yet to emerge. These technological advancements are crucial for improving fuel efficiency and reducing carbon footprints.
2. Operations and Infrastructure: Enhancing operational efficiencies and optimizing fuel use are critical. This includes innovations like fuel-saving flight techniques and improved infrastructure to support sustainable operations.
3. Alternative Fuels: The development and adoption of Sustainable Aviation Fuels (SAFs) are pivotal. Hörlin discusses various types of SAFs, including HEFA (Hydroprocessed Esters and Fatty Acids), alcohol-to-jet fuels, and synthetic fuels produced from direct carbon capture. Hydrogen and electric fuels also hold promise for the future.
4. Market-Based Measures: These include initiatives like carbon offsetting and direct carbon capture, providing additional ways to balance emissions that cannot be completely eliminated through technology or operational improvements.
SAS's Commitment to Sustainability
Scandinavian Airlines (SAS) has been at the forefront of aviation sustainability for over 25 years. Hörlin proudly shares SAS's longstanding commitment to fuel efficiency, starting from cost-saving measures to becoming a leader in sustainable aviation. This commitment is reflected in their pilots' exceptional fuel efficiency training and the airline's continuous innovation in sustainability practices.
Strategic Partnerships and Innovations
SAS recognizes that collaboration is essential to achieving their sustainability goals. Hörlin highlights their partnership with Airbus, exploring the potential of hydrogen-powered flights. Although the technology and infrastructure for liquid hydrogen are not yet available, this partnership represents a significant step towards future sustainable aviation.
SAS is also pioneering in electric aviation. Hörlin discusses their electric two-seater aircraft, Pipistrelle, used for pilot training and short flights, showcasing the practical applications of electric flight technology.
The Path Forward: Challenges and Opportunities
While the path to net-zero aviation is challenging, Hörlin remains optimistic. The biggest immediate impact can be achieved by updating fleets with more fuel-efficient aircraft, which are 20-30% more effective than their predecessors. Sustainable Aviation Fuels, although currently costly and limited in supply, offer a significant opportunity for carbon reduction.
Hörlin also touches on the political and regulatory landscape, particularly the European Union's approach to mandates and subsidies for SAFs. She highlights the need for balanced policies that support both production and affordable access to these fuels.
The Importance of Collaboration
Throughout her presentation, Hörlin emphasizes the importance of industry-wide collaboration. From manufacturers and airlines to airports and policymakers, achieving net-zero emissions requires a unified effort. SAS's partnerships with other airlines, manufacturers like Airbus, and various airports exemplify this collaborative approach.
SAS's Commitment to a Sustainable Aviation Future
Ann-Sofie Hörlin's session at New York Energy Week 2024 underscores SAS's role as a leader in aviation sustainability. Her insights into the industry's ambitious goals, the innovative strategies being employed, and the collaborative efforts required to achieve net-zero emissions highlight the complexity and necessity of this endeavor. As SAS continues to pioneer energy efficiency in aviation, Hörlin's leadership and vision are vital in guiding the industry towards a more sustainable future.
