Renewable Energy
Airbus has been actively developing its ZEROe program, with a clear focus on hydrogen-powered aircraft through fuel cell technology. While early concepts were unveiled in 2020, recent announcements in 2025 suggest a delay in commercial deployment beyond 2035. Meanwhile, Airbus continues investing in cryogenic storage, fuel-cell demonstrators, and even superconducting electric propulsion. At the same time, biofuels (SAF, e-fuels) are gaining traction as a transitional solution with more immediate deployment potential. 🔍 Based on your experience and current policy, infrastructure, and technology trends, how realistic do you see Airbus deploying hydrogen aircraft—or integrating large-scale biofuels—before 2030? Could we expect significant breakthroughs in regional aviation or hybrid propulsion in the next 5 years? I’d love to hear your perspectives, especially from those involved in H₂ infrastructure, aviation fuels, or aerospace engineering.

Quick Take from a Petroleum Engineer: The Realities of Hydrogen and Biofuels in Aviation
As a petroleum engineer by profession, I’m closely watching the energy transition and how it intersects with sectors like aviation. Airbus’s vision of deploying hydrogen-powered aircraft and integrating biofuels at scale is ambitious but it’s not without real-world constraints.
Hydrogen: High Potential, High Hurdles
Hydrogen-powered aircraft are technically feasible. But challenges remain in storage, safety, and infrastructure. Hydrogen’s low volumetric energy density means you need large cryogenic tanks, which disrupt aircraft design and payload efficiency. For short-haul flights or regional aircraft, hydrogen could become viable within the next two decades especially if green hydrogen production scales and airport refueling standards mature.
Biofuels: More Immediate but Supply-Limited
Biofuels, especially sustainable aviation fuel (SAF), present a more realistic short- to mid-term path. They can be used in current engines with minimal modifications and provide up to 80% lifecycle emission reduction. However, the main barrier is feedstock availability and cost. As a petroleum engineer, I see potential in refining waste oils and non-food biomass but scaling that to meet global jet fuel demand is a monumental task.
Bottom Line
From an engineering and market-readiness perspective:
Hydrogen is a long game, with 2035–2040 as the earliest realistic timeline for commercial deployment.
Biofuels are today’s transitional solution, but they need massive policy and supply chain support to scale affordably.
We need parallel innovation tracks: advancing aircraft design, reforming fuel policies, and investing in refining tech that bridges petroleum and renewables.
