Joby Air Taxi Explores Hydrogen for Extended Range

Joby Air Taxi Explores Hydrogen for Extended Range
Pioneering Electric Aviation
When JoeBen Bevirt founded Joby Aviation in 2009, electric aircraft were largely an uncharted frontier. At a time when Tesla had just introduced its first electric car, few anticipated that electric propulsion would soon extend beyond automobiles to reshape the aviation industry. Bevirt, however, envisioned electric vertical take-off and landing aircraft (eVTOLs) as a transformative solution for urban transportation.
Joby distinguished itself from traditional aerospace manufacturers by adopting a rapid, iterative design methodology known internally as “design, build, and test.” Jon Wagner, former Tesla battery engineering director and now Joby’s head of powertrain, emphasized that this approach enabled the company to swiftly identify and resolve design challenges. Wagner noted, “If you have a very good system for going through that iterative process quickly and at a low cost, then you can take risks, because if it fails, you just go again.”
With no established supply chain for electric aircraft, Joby applied this iterative process to every component of its eVTOL, focusing particularly on the electric powertrain. The company experimented with multiple generations of geared electric motors before Wagner spearheaded the development of a direct-drive motor. This innovation improved reliability and performance while reducing noise, marking a significant advancement in eVTOL propulsion technology.
Advancing Certification and Exploring Hydrogen
As Joby’s S4 eVTOL air taxi progresses through certification with the U.S. Federal Aviation Administration (FAA), the company is simultaneously investigating hydrogen as a potential means to extend the aircraft’s operational range. This strategic exploration comes amid heightened regulatory scrutiny and intensifying competition within the advanced air mobility sector. The FAA’s close oversight of Joby’s certification process reflects both the challenges and opportunities that eVTOLs present for the future of urban flight.
Despite these promising developments, Joby faces significant hurdles. The company is currently engaged in legal disputes with rival Archer Aviation, which has accused Joby of misrepresenting its relationships with foreign entities—particularly in China—and of mislabeling imports. These allegations threaten to undermine Joby’s credibility and could complicate its efforts to secure government contracts, injecting uncertainty into its trajectory.
Meanwhile, competitors such as Eve Air Mobility are advancing rapidly, having secured substantial funding and progressed with their own flight testing programs. The competitive landscape is becoming increasingly fierce as multiple companies race to bring certified eVTOLs to market.
Commitment to Innovation Amid Challenges
Joby remains steadfast in its focus on technical innovation. Wagner described the company’s electric motor as a direct-drive system with a large diameter designed for high torque density, enabling propellers to operate more slowly and quietly than conventional designs. The motor incorporates redundancy through dual sets of coils and inverters, each powered by separate batteries, and is equipped with an advanced thermal management system to reduce weight.
As Joby navigates regulatory complexities, legal challenges, and a rapidly evolving market, its dedication to innovation—including the exploration of hydrogen power—continues to be central to its vision of revolutionizing urban mobility.
