H55, the Swiss specialist in certified electric propulsion and aviation energy storage, has supplied Czech aircraft manufacturer BRM Aero with conforming certifiable battery modules for the next stage of integrating the fully electric Bristell B23 Energic aircraft. The new modules support advanced mechanical integration and move the programme closer to full aircraft‑level validation.
This marks a major step toward commercial rollout, with initial deliveries expected in late 2027. With firm orders already placed across Europe and the United States, production capacity for the first two years is secured. The achievement reinforces H55’s capability to provide certification‑ready, adaptable energy storage solutions that meet both integration and operational demands.
“The delivery of conforming modules marks a key step toward commercialising the Bristell B23 Energic,” said Rob Solomon, CEO of H55. “With strong market demand already materialising, we are now moving decisively from development into scaled execution.”
“The Bristell B23 Energic represents a major step forward in making electric aviation a practical reality for pilot training,” added Martin Bristela, CEO of BRM Aero. “Working with H55 allows us to integrate a propulsion solution that meets both certification and operational requirements, bringing us closer to delivering a commercially viable electric aircraft.”
Developed with BRM Aero, the B23 Energic targets the fast‑growing electric pilot training sector. The aircraft offers zero‑emission flying, reduced operating and maintenance costs, and the performance required for intensive training. Its electric propulsion system delivers quieter operation, lower energy use, and simplified upkeep compared with piston aircraft. Designed for certification and scalability, it provides flight schools with a realistic route to decarbonising fleets while maintaining safety and efficiency.
