From the outside looking in, it could seem that aviation is giving up on hydrogen<\/a><\/span><\/strong>.<\/p>\n\n\n\n

Airbus<\/a><\/span><\/strong> has pushed back the timeline for its ZEROe<\/a><\/span><\/strong> hydrogen airliner programme into the 2030s. Infrastructure concerns continue to dominate industry discussions, while several high-profile hydrogen projects have struggled to move beyond testing and demonstration phases.<\/p>\n\n\n\n

But H2Fly<\/a><\/span><\/strong> CEO Ralph M\u00fcller believes the industry may simply be looking in the wrong place.<\/p>\n\n\n\n

Speaking exclusively to Aerospace Global News, M\u00fcller argued that hydrogen flight is unlikely to begin with large commercial airliners. Instead, he sees the industry\u2019s first viable hydrogen aircraft emerging in regional aviation, special mission platforms and smaller utility aircraft, where certification, infrastructure and operational barriers are far easier to overcome.<\/p>\n\n\n\n

At the same time, H2Fly is increasingly positioning itself not simply as an aircraft developer, but as part of a broader hydrogen aviation ecosystem spanning propulsion, storage, airport infrastructure and operational integration.<\/p>\n\n\n\n

The German company recently announced plans to evolve beyond pure research and demonstration work into a more commercially focused operation,<\/a><\/span><\/strong> building on years of hydrogen-electric flight testing.<\/p>\n\n\n\n

\u201cWe see hydrogen aviation happening step by step,\u201d M\u00fcller said. \u201cYou don\u2019t need to solve the entire aviation industry in one go.\u201d<\/p>\n\n\n

Hydrogen aviation may begin far below the Airbus scale<\/h2>\n\n\n\n

While much of the public discussion around hydrogen aviation centres on future narrowbody aircraft carrying 100 to 200 passengers, H2Fly is deliberately targeting a far smaller segment of the market.<\/p>\n\n\n\n

Its hydrogen-electric fuel cell technology is currently being developed for aircraft carrying up to 19 passengers, alongside utility aircraft and emerging advanced air mobility platforms.<\/p>\n\n\n\n

For M\u00fcller, starting small is not a compromise, but the most realistic route to commercial entry.<\/p>\n\n\n\n

\u201cThe market for smaller aircraft can start earlier because it\u2019s less complex,\u201d he explained. \u201cCertification should require less time and lower cost, so it becomes much more feasible as an entry point.\u201d<\/p>\n\n\n\n

Unlike major commercial airports, smaller regional operations may also be able to adopt hydrogen infrastructure incrementally.<\/p>\n\n\n\n

\u201cTo accomplish a 1,000-kilometre flight, you may only need 30 to 40 kilograms of liquid hydrogen,\u201d M\u00fcller said. \u201cThat\u2019s something you can deliver to an airport much more easily. You don\u2019t immediately need large-scale pipelines or massive infrastructure investments.\u201d<\/p>\n\n\n\n

Rather than waiting for a fully mature global hydrogen ecosystem, M\u00fcller believes regional aviation can begin building operational experience using modular fuelling systems and smaller-scale supply chains.<\/p>\n\n\n\n

That gradual scaling model increasingly contrasts with the enormous infrastructure challenge facing larger hydrogen-powered airliner concepts.<\/p>\n\n\n

H2Fly is building a wider hydrogen aviation ecosystem<\/h2>\n\n\n\n

M\u00fcller also suggested the next phase of hydrogen aviation will depend less on individual aircraft programmes and more on building a wider operational ecosystem.<\/p>\n\n\n\n

Rather than positioning H2Fly purely as an aircraft manufacturer, the company increasingly sees itself as an enabler for hydrogen-powered operations across aviation.<\/p>\n\n\n\n

\u201cWe don\u2019t only look at the aircraft itself,\u201d M\u00fcller explained. \u201cYou also need the infrastructure, the operational integration, the fuelling concepts and the certification environment.\u201d<\/p>\n\n\n\n

That shift reflects a broader change underway across hydrogen aviation.<\/p>\n\n\n\n

Early industry discussion often focused heavily on aircraft concepts and propulsion demonstrations. But attention is now moving toward the practical realities of how hydrogen-powered aviation would actually function day to day.<\/p>\n\n\n\n

For H2Fly, that includes working with airports, infrastructure providers and operators to develop scalable operational models around liquid hydrogen handling and refuelling.<\/p>\n\n\n\n

The company believes regional airports may ultimately become some of the first realistic proving grounds for hydrogen operations, particularly where traffic volumes are lower and operational complexity is easier to manage.<\/p>\n\n\n\n

M\u00fcller argued that this phased approach is essential if hydrogen aviation is to move beyond isolated demonstrators and into repeatable commercial service.<\/p>\n\n\n\n

\u201cYou need the complete ecosystem to mature together,\u201d he said. \u201cOtherwise, the aircraft alone is not enough.\u201d<\/p>\n\n\n

\n\n\n\n

Liquid hydrogen vs hydrogen combustion: Where H2Fly stands<\/h2>\n\n\n\n

A major part of H2Fly\u2019s strategy centres on liquid hydrogen rather than compressed gaseous storage, which M\u00fcller believes will ultimately become necessary for meaningful aircraft range and scalability.<\/p>\n\n\n\n

The company has already conducted flight testing using liquid hydrogen fuel cell systems, including its HY4 demonstrator programme.<\/p>\n\n\n\n

Liquid hydrogen is increasingly emerging as the preferred long-term option for several major hydrogen aviation projects because of its far higher energy density by volume compared with compressed gas.<\/p>\n\n\n\n

Airbus reached a similar conclusion during its ZEROe studies, with the company ultimately focusing heavily on liquid hydrogen storage concepts for future commercial aircraft.<\/p>\n\n\n\n

\u201cThe higher energy density is critical,\u201d M\u00fcller explained. \u201cIf you want larger aircraft and longer ranges, liquid hydrogen becomes very important.\u201d<\/p>\n\n\n\n

However, hydrogen aviation remains split between multiple competing technological pathways. H2Fly is focused on hydrogen-electric propulsion using fuel cells, where hydrogen generates electricity to power electric motors.<\/p>\n\n\n\n

\"Rolls-Royce

Elsewhere, companies including Rolls-Royce and easyJet are pursuing hydrogen combustion<\/a><\/span><\/strong> instead, modifying gas turbine engines to burn hydrogen directly. M\u00fcller does not necessarily view such efforts as direct competitors.<\/p>\n\n\n\n

\u201cThere will probably not be one single solution,\u201d he said. \u201cDifferent applications may use different technologies.\u201d<\/p>\n\n\n\n

Fuel cells are generally seen as highly efficient for smaller aircraft and regional operations, while hydrogen combustion may ultimately prove more practical for larger, faster aircraft where power density becomes more critical.<\/p>\n\n\n\n

For now, the hydrogen aviation sector remains fragmented across multiple technologies, timelines and operational concepts. But M\u00fcller believes that does not signal failure.<\/p>\n\n\n\n

Instead, he sees an industry gradually moving away from ambitious headline promises and toward the slower, more practical work of building real operational capability.<\/p>\n\n\n\n

\u201cThe industry is learning where hydrogen makes sense first,\u201d he said. \u201cThat\u2019s a normal development process.\u201d<\/p>\n\n\n
