The startup Aerostrad, based at the Energypolis Campus in Sion, is tackling a problem largely unknown to the general public: the energy consumption of aircraft on the ground. Founded by Elie Maalouli, a Canadian-Lebanese engineer with 15 years of experience in electric mobility, the company is developing portable, autonomous energy solutions for airports. Supported by The Ark Foundation in 2025, the startup aims to deploy its first proof of concept in 2026.
“Before takeoff or after landing, the plane’s engines are running,” explains Elie Maalouli. The energy required to power the aircraft’s systems generally comes from burning jet fuel or diesel. The figures are telling. “Half an hour of the aircraft being on standby is equivalent to a flight from Geneva to Milan. This results in a significant amount of wasted energy and high CO2 emissions, without the aircraft even moving.” It is precisely to address this energy waste that Aerostrad developed its technology.
A mobile power solution for airports
Aerostrad’s solution is a portable, self-contained power system that can be moved to wherever power is needed at the airport. This approach makes it possible to power aircraft on the ground without relying on traditional diesel generators.
From a technical standpoint, the startup has opted for a proven technology. “For now, we’re using lithium because it’s already established and production costs remain low, while also fitting into the airport’s existing infrastructure,” explains the founder. This means there’s no need to develop new infrastructure.
What sets Aerostrad apart in its development is its early-stage business approach. “We’ve built relationships with airports and identified potential customers to understand their needs and tailor our product to support them,” explains Elie Maalouli. The startup targets two types of customers: airports and ground handling operators.
A proof of concept in 2026
The year 2025 marked a first step for Aerostrad as it entered the pre-incubation phase with The Ark Foundation. For 2026, the plan is to develop a “proof of concept.” Elie Maalouli hopes this can be done in Sion.
This phased rollout strategy should enable Aerostrad to validate its technology under real-world conditions before expanding to larger airports. It’s a bold move for this Valais-based startup, which aims to help decarbonize the airport sector.
