Could Honda's Sustainable Aviation Fuel Redefine Air Travel?

In a major step forward for aviation sustainability, Honda Aircraft Company's HondaJet has successfully completed a test flight using 100% sustainable aviation fuel (SAF), paving the way for a significant reduction in the industry's carbon footprint.

Honda Aircraft Company has taken a major step in aviation sustainability by successfully conducting a test flight powered entirely by a 100% blend of sustainable aviation fuel (SAF).

The achievement marks a first for a twin-turbine very light business jet manufacturer and highlights the industry's progress toward reducing its environmental footprint.

According to the International Civil Aviation Organization, aviation contributes 12% of all carbon dioxide emissions from global transportation.

In response, manufacturers like Honda Aircraft Company are developing technologies to lower these emissions, with a strong focus on alternative fuels.

Sustainable aviation fuel and emissions reduction

Sustainable aviation fuel is an alternative to traditional jet fuel derived from non-petroleum renewable sources such as woody biomass, fats and greases. It is currently approved for use in commercial flights in blends of up to 50% with conventional fuel.

The adoption of SAF presents several advantages, including flexibility in production technologies and compatibility with existing engine and airport infrastructure.

Its use in a 100% blend could reduce greenhouse gas emissions by up to 94% compared to conventional jet fuel.

The milestone flight took place over Greensboro, North Carolina, US, with the HondaJet landing at Honda Aircraft Company's headquarters at Piedmont Triad International Airport.

This follows successful ground tests of the aircraft's HF120 engine using 100% SAF in 2022 and 2023.

Amod Kelkar, Senior Vice President and Chief Commercial Officer at Honda Aircraft Company, says: “We are immensely proud of our Honda Aircraft Company engineering team carrying forward our commitment to the future of aviation by demonstrating that the HondaJet is capable of operating on a 100% SAF blend.

"This achievement is a step toward aligning our business activities with the global Honda goal of decarbonising our business activities by 2050.”

Advanced engine technology and efficiency

Established in 2006 as a wholly-owned subsidiary of Honda Motor Company, Honda Aircraft Company has consistently focused on fuel efficiency through advanced aerodynamic designs.

Honda Aircraft Company's headquarters is a LEED GOLD-certified building recognised for its environmental and social benefits.

A key component of Honda Aircraft Company's efficiency strategy is the HF120 engine. Developed from the earlier HF118 engine technology, the HF120 was created in collaboration with General Electric.

The result is a jet engine that offers improved efficiency, leading to lower fuel consumption and reduced noise. Honda prioritised low emissions in the engine's design, making it a cornerstone of Honda Aircraft Company’s environmental objectives.

Accreditation and a sustainable future

The National Business Aviation Association (NBAA) has awarded Honda Aircraft Company its Tier-six Sustainable Flight Department Accreditation.

This is the highest level of recognition from the NBAA, acknowledging Honda Aircraft Company's commitment to a sustainable future for aviation.

Honda Aircraft Company earned this for its increased use of SAF, improving the fuel efficiency of the HondaJet and implementing other measures to minimise the environmental impact of its aircraft.

Hideto Yamasaki, President of Honda Aircraft Company, says: “We are very proud of our Flight Department’s efforts in attaining this accreditation. Their work fully embodies the spirit of Honda.

"The plan they have outlined will go to further Honda’s broader corporate policy, which aims to realise net zero carbon emissions for all business operations by the year 2050.”

Moving forward, Hideto explains that Honda Aircraft Company plans to reinforce its leadership position in developing a more sustainable future for the aviation sector.
