H55, a Swiss-based leader in certified electric propulsion and energy storage systems for aviation, has delivered conforming certifiable battery modules to BRM Aero to support the next phase of integration of the fully electric Bristell B23 Energic aircraft.

These modules will advance mechanical integration, marking a key step toward aircraft-level validation of the electric propulsion system.

This milestone represents a significant step toward commercialization, with first deliveries planned in late 2027. Based on orders received to date in both the United States and Europe, production capacity is already secured for the first two years of operations.

This achievement further demonstrates H55's ability to deliver certification-ready, adaptable energy storage systems supporting both integration and operational requirements across aircraft programs.

"The delivery of conforming modules marks a key step toward commercializing the Bristell B23 Energic," said Rob Solomon, CEO of H55. "With strong market demand already materializing, 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," said 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."

The Bristell B23 Energic program, developed in partnership with BRM Aero, targets the rapidly growing electric pilot training market. The aircraft combines zero-emission operations with significantly reduced operating and maintenance costs, while maintaining the performance and reliability required for intensive training. Its electric propulsion system enables quieter flights, lower energy consumption, and simplified maintenance compared to conventional piston aircraft. Designed with certification and scalability in mind, the B23 Energic provides flight schools with a practical pathway to decarbonize their fleets without compromising operational efficiency or safety.
