The electric aircraft market is just beginning to take off, and according to IDTechEx, this market holds enormous potential for transforming the aviation industry. Currently, only a few electric planes are available, such as the Pipistrel Velis Electro, which has seen strong demand since its debut in 2020. With the electric general aviation market predicted to grow at a 35.7% CAGR between 2025 and 2035, electric and hydrogen-powered planes offer new opportunities for reducing greenhouse gas (GHG) emissions and creating a more sustainable aerospace industry.
Strategic Deployment of Electric Airliners
While electric powertrains are gaining momentum in small planes, commercial airliners face greater challenges. The weight of batteries makes achieving long ranges difficult, as large amounts of fuel must be burned off before landing to meet maximum weight restrictions. Future developments in battery technology may help, but electric airliners will likely be limited to short, high-traffic routes for now, such as Los Angeles to San Francisco or London to Frankfurt. Improvements in battery efficiency, plane design, and landing weight capacities could open new possibilities.
Hydrogen: The Next Big Player
Hydrogen presents a promising alternative, with energy density far surpassing current battery technology. However, hydrogen’s volumetric limitations, requiring pressurization or cryogenic storage, make it challenging to integrate into existing aircraft designs. Despite these hurdles, hydrogen-powered planes could play a key role in fulfilling air travel demand, especially when sourced sustainably. Green hydrogen, while the most environmentally friendly, remains costly. Blue and grey hydrogen offer lower-cost alternatives, but with varying levels of carbon emissions.
The Role of Sustainable Aviation Fuel (SAF)
Even as electric and hydrogen technologies advance, Sustainable Aviation Fuel (SAF) remains critical to decarbonizing aviation by 2050. Many existing aircraft will continue to operate for decades, making SAF the most viable option for reducing emissions in the short to medium term. As an affordable, drop-in replacement for conventional fuels, SAF will likely be essential for older airframes and long-haul routes where battery and hydrogen options fall short.
