Plug Power, a global leader in comprehensive H₂ solutions for the green H₂ economy, Airbus, Hartsfield-Jackson Atlanta International Airport (ATL), and Delta Air Lines have joined forces to study the feasibility of a H₂-based hub at the world’s busiest airport in support of advancing a more sustainable future of travel.

The study, which was preliminarily launched earlier this year, will help define the infrastructure, operational viability, and safety and security requirements needed to implement H₂ as a fuel source for future aircraft operations at ATL. It will also contribute to the understanding of H₂ supply and infrastructure requirements at airports around the world.

The use of H₂ to power future aircraft could ultimately eliminate aircraft CO₂ emissions in the air, while also decarbonizing air transport activities on the ground. This study reflects the partners’ ambition to use their respective expertise to support the decarbonization of the aviation industry.

Plug is a leading provider of equipment and end-to-end, turnkey solutions for the global green H₂ economy. The company is building an end-to-end green H₂ ecosystem including the manufacture of electrolyzers, fuel cells and H₂ facilities across the U.S. to decarbonize a variety of industrial, transportation and energy needs and applications worldwide.

“The potential to decarbonize aviation with green H₂ is substantial,” said Plug CEO Andy Marsh. “We are pleased to contribute our expertise in H₂ infrastructure and applications development to this pioneering effort at Hartsfield-Jackson Atlanta International Airport. We have a ready-made supply of green H₂ to support the airport from our new Woodbine, Georgia, production plant, the largest green H₂ plant in the U.S.”

Airbus pioneers sustainable aerospace for a safe and united world. The company constantly innovates to provide efficient and technologically advanced solutions in aerospace. Airbus is currently developing the first H₂-powered commercial aircraft with the ambition to enter into service in 2035 and promoting the H₂ Hubs at Airports concept.

“The U.S. has easy and massive access to additional renewable energies to produce green H₂, and airports are looking for a diverse and balanced energy mix to help reduce the impact of aviation on the environment. H₂ is a key enabler for this,” said Karine Guénan, Airbus’ Vice President ZEROe H₂ Ecosystem. “The journey to prepare airport infrastructure to support H₂ and low carbon aviation begins on the ground with studies like this one, working with pioneer players like Delta, Plug and the world’s busiest airport.”

“Hartsfield-Jackson has long been a leader in the commercial aviation industry, and it only makes sense that we help lead this effort,” said ATL Senior Deputy General Manager Michael Smith. “If H₂ proves to be a viable alternative, ATL will investigate options to update infrastructure needs in order to implement the new technology. We are thrilled to participate in this study and look forward to the results.”

As part of the study, ATL is providing the current airport layout plan and organization and will share updates on future developments and findings.

Delta is the largest airline operating at the world’s busiest airport and offers one of the largest commercial airline schedules globally. Delta has been a long-standing core partner in the Airbus ZEROe program since 2022 when it signed on to provide expertise to identify fleet and network expectations, and the operational and infrastructure requirements needed to develop commercial aircraft powered by H₂ fuel. Delta’s Chief Sustainability Officer Amelia Deluca said this study is part of Delta’s ongoing commitment and that no one company can solve the industry’s sustainability challenges alone.

“All aviation stakeholders need to explore new paths in every direction today if the industry is going to reach a more sustainable future of travel by 2050,” she said. “While we work to scale sustainable aviation fuel to power today’s aircraft, H₂ is the key to unlocking the decarbonized future of flight and the next generation of aviation. That’s why we are excited to be part of this journey to help map the industry’s H₂ blueprints with partners who share our passion for connecting the world.”

Airbus launched the “H₂ Hub at Airports” program to jumpstart research into infrastructure requirements and low-carbon airport operations across the entire value chain. To date, agreements have been signed with partners and airports in ten countries including France, Germany, Italy, Japan, New Zealand, Norway, Singapore, South Korea, Sweden and the United Kingdom.

The study in Atlanta is scheduled for completion at the end of 2026.
