HevenDrones, a leader in hydrogen-powered drone technology, has announced the acquisition of Zepher Flight Labs (ZFL), a move that enhances its modular, long-endurance unmanned aerial systems (UAS) for defense and commercial applications.






The acquisition, announced on April 25, 2025, aims to integrate Zepher's expertise in vertical takeoff and landing (VTOL) drones with HevenDrones' hydrogen fuel cell technology. This synergy is expected to produce drones capable of operating from remote, infrastructure-limited environments, addressing the need for long-range, low-maintenance aerial platforms in military operations.


Bentzion Levinson, CEO of HevenDrones, stated,


"This acquisition strengthens our position in the market and underscores our commitment to providing the most advanced and reliable drone solutions." 

Adam Stolz, CEO of Zepher Flight Labs, added,

"Teaming up with Heven means we can accelerate what we’ve always aimed to do: push drone technology to the edge of what’s possible."

The integration of Zepher's lightweight, quick-deployable drones with HevenDrones' hydrogen propulsion systems is anticipated to result in UAS with extended flight times and increased payload capacities. This development is particularly significant for military applications requiring persistent surveillance and logistics support in austere environments.

FAQ: Hydrogen Aviation Basics


  1. What is hydrogen aviation?

    1. Hydrogen aviation refers to the use of hydrogen fuel cells or hydrogen combustion to power aircraft, offering a cleaner alternative to traditional fossil fuels.

  2. How do hydrogen fuel cells work in aircraft?

    1. Hydrogen fuel cells generate electricity through a chemical reaction between hydrogen and oxygen, producing water vapor as the only emission, which powers electric motors in aircraft.

  3. What are the benefits of hydrogen-powered drones?

    1. They offer longer flight times, higher payload capacities, reduced noise, and zero carbon emissions compared to battery-powered drones.

  4. Are hydrogen-powered aircraft safe?

    1. Yes, with proper handling and storage, hydrogen is a safe fuel. Modern technologies ensure its safe use in aviation applications.

  5. What challenges does hydrogen aviation face?

    1. Challenges include developing infrastructure for hydrogen production and refueling, storage solutions, and ensuring cost-effectiveness.

  6. How long can hydrogen-powered drones fly?

    1. Depending on design, some hydrogen drones can fly for several hours, significantly longer than battery-powered counterparts.

  7. Is hydrogen aviation environmentally friendly?

    1. Yes, it produces zero carbon emissions during operation, contributing to reduced greenhouse gas emissions in aviation.

  8. What is the cost comparison between hydrogen and traditional aviation fuels?

    1. Currently, hydrogen can be more expensive, but advancements in production and increased demand are expected to lower costs over time.

  9. Are there commercial hydrogen-powered aircraft?

    1. Several prototypes and small aircraft are in testing phases, with commercial models expected in the coming years as technology matures.

  10. How does hydrogen aviation impact the economy?

    1. It has the potential to create new industries and jobs in hydrogen production, infrastructure development, and aircraft manufacturing, contributing to economic growth.
