There are more solutions than obstacles. Nicolas Zart
Electric air mobility continues its climb with advancements in energy, batteries, and propulsion systems. From experimental nuclear reactors supporting clean power to sodium-ion battery progress breathing new life to power-hungry multiport operations and new electric propulsion platforms for general aviation, here’s a roundup of key developments shaping the future of sustainable flight and urban air mobility.
Nuclear Innovation for Reliable Clean Energy
French molten salt reactor developer Stellaria has signed a letter of intent with the CEA to explore building its Alvin experimental MSR at the Cadarache site. The 100 kW Alvin reactor would validate modeling for the technology targeted for startup around 2030. Next will be the 10 MWe MegAlvin prototype. Stellaria aims for its compact Stellarium commercial reactor by 2035, capable of using diverse fuels and destroying more waste than it produces. This lands perfectly with the uptake in advanced air mobility’s (AAM) commercial ramp when mega watts of power are going to be needed during peak time when utilities and grids won’t be able to handle the growing demand.
In the US, the University of Illinois Urbana-Champaign and NANO Nuclear Energy have submitted a construction permit application to the NRC for the first research KRONOS micro modular reactor (MMR) on campus. The high-temperature gas-cooled design would repower part of the university’s coal-fired power station, demonstrating integration with existing infrastructure for zero-carbon heat and power as part of a green campus initiative.
These steps highlight growing interest in advanced nuclear as a dense, reliable low-carbon energy source—potentially key for charging networks and high-power operations in future electric aviation and eVTOL infrastructure.
Sodium-Ion Batteries Emerge as Lithium Alternative
Sodium-ion technology is achieving more breakthroughs. With lower-cost options once mass-manufactured amid volatile lithium prices, these batteries are highly suitable for EVs and stationary energy storage. As far as electric aircraft propulsion and AAM infrastructure energy, the battery’s weight, cost, and supply chain resilience on scarcer materials could find a perfect fit there.
MagniX Launches MagniAIR for General Aviation
On the electric propulsion front, MagniX unveiled its MagniAIR engine for general aviation. Targeting replacement of 120-175 kW piston engines, the air-cooled, zero-emission unit offers a strong power-to-weight ratio (175 kW at 55 kg). The operating costs and maintenance needs will be lower than that of conventional internal combustion engines (ICE).
The motor should be available in 2027. The company is currently working in its integration in a Van’s RV-10 kit plane for demonstration flights. This engine could fit the light-sport aircraft under updated rules. In the meantime, MagniX continues active FAA certification work alongside other electric propulsion projects.
Urban Air Mobility Outlook
A new market overview from ePlane AI puts the global flying cars and UAM market at $117 million in 2025, on a trajectory to $1.39 billion by 2033 at a 36% compound annual growth rate.
Joby Aviation continues advancing toward FAA certification with step three of five.
Archer‘s Midnight is accumulating test hours.
Southeast Asia is seeing early commercial eVTOL operations through EHang in Thailand.
The overview is that the technology continues it march forward, the capital only to the vehicle makers leaving infrastructure under-invested creating an operation bottleneck, and the regulatory frameworks are progressing. The remaining challenge is funding infrastructure so that operations can begin according to OEM’s predictions, certification timelines are kept and clearly explained – something they are not as of these days, and public desirability grows along with trust. We are now in the sustained effort leaving flashy breakthrough moments behind the scene.
