COMUNICATO STAMPA – CONTENUTO PROMOZIONALE<\/p>\n

SION,\u00a0Switzerland, Feb. 2, 2026 \/PRNewswire\/ — Electric aviation has faced a single, unresolved bottleneck: proving to regulators that high-energy propulsion batteries can safely contain worst-case failures.\u00a0<\/p>\n

\u00a0\u00a0<\/p>\n

\u00a0\u00a0<\/p>\n

H55 today announces that it has completed the industry’s first regulator-required and authority-witnessed\u00a0propulsion\u00a0battery module\u00a0certification\u00a0test\u00a0sequence\u00a0\u2014\u00a0addressing\u00a0a critical gating factor that has constrained the commercialisation and financing of electric aircraft programs.\u00a0<\/p>\n

Completed on December 19, 2025, the EASA-supervised\u00a0campaign places H55 at the forefront of efforts\u00a0to\u00a0establish\u00a0certification-grade,\u00a0aviation-safe\u00a0propulsion\u00a0battery\u00a0systems, setting\u00a0the\u00a0standards against which future programs will be assessed.\u00a0The campaign provides certification-level evidence that commercial lithium battery cells can be integrated into aviation propulsion battery systems capable of safely containing worst-case failure scenarios, especially fire propagation.\u00a0<\/p>\n

From\u00a0Validation\u00a0to\u00a0Scalable\u00a0Certification\u00a0<\/p>\n

This\u00a0milestone\u00a0goes\u00a0beyond\u00a0documenting\u00a0or\u00a0promising\u00a0safety\u00a0performance.\u00a0It\u00a0confirms\u00a0H55’s\u00a0ability to engineer and manufacture propulsion battery systems developed to certification standards on regulatory-approved manufacturing lines and supply chains.\u00a0<\/p>\n

The\u00a0test\u00a0campaign was\u00a0conducted\u00a0in\u00a0a\u00a0certified\u00a0production\u00a0facility\u00a0using serial-conforming\u00a0hardware (not prototypes) manufactured through validated processes.\u00a0It confirms H55’s ability to engineer and manufacture propulsion battery systems built to certification standards on regulatory-approved manufacturing lines and supply chains.\u00a0<\/p>\n

H55’s unique, patented Energy Storage System design embeds monitoring, redundancy, and hazard\u00a0mitigation\u00a0at\u00a0the\u00a0cell\u00a0level\u00a0as\u00a0foundational\u00a0principles,\u00a0ensuring\u00a0containment\u00a0of\u00a0extreme\u00a0failure conditions consistent with aviation safety requirements.\u00a0<\/p>\n

This\u00a0approach\u00a0establishes\u00a0a\u00a0repeatable\u00a0certification\u00a0pathway\u00a0for\u00a0H55’s battery\u00a0technology,\u00a0rather than advancing a single aircraft programme.\u00a0By defining a certification-grade battery module reference framework, H55 materially reduces adoption risk for aircraft manufacturers, operators, insurers, and investors by enabling actuarial risk assessment based on authority-validated failure data rather than programme-specific assumptions.\u00a0With certification evidence able to compound across a wide range of aircraft platforms, capital, engineering resources, and industrial capacity can expand without proportional increases in programme-level uncertainty.\u00a0<\/p>\n

The system foundations established through H55’s first conforming propulsion battery system now support accelerated development and regulatory progress for both fully electric and hybrid-electric aircraft.\u00a0The\u00a0data,\u00a0infrastructure,\u00a0and\u00a0certification-standard\u00a0evidence produced\u00a0through\u00a0this\u00a0campaign underpin multiple ongoing customer programmes, including the BRM B23 Energic, CAE’s transition toward all-electric pilot training platforms, and the hybrid-electric Dash 8 demonstration programme with Pratt & Whitney Canada.\u00a0<\/p>\n

With more than 20 years of electric aviation experience, six electric aircraft designed, built, and flown, and over 2,000 fully electric flight hours accumulated with zero battery-related incidents, H55 brings the operational depth required to execute certification-grade programmes \u2014 not merely comply with them.\u00a0<\/p>\n

Andr\u00e9\u00a0Borschberg,\u00a0Executive\u00a0Chairman\u00a0and\u00a0Co-Founder\u00a0of\u00a0H55,\u00a0said:\u00a0<\/p>\n

“H55\u00a0was\u00a0created\u00a0with\u00a0a\u00a0single objective:\u00a0to\u00a0make\u00a0electric\u00a0aviation certifiable,\u00a0not\u00a0just\u00a0possible.\u00a0From the outset, that meant designing systems around aviation safety standards and preventing failure while optimising performance.\u00a0<\/p>\n

This milestone validates that choice.\u00a0Electric aviation can be engineered to meet the same certification\u00a0discipline\u00a0and\u00a0safety\u00a0expectations\u00a0as\u00a0conventional\u00a0aircraft. At\u00a0H55,\u00a0disciplined,\u00a0focused ambition\u00a0is what translates certification into real market adoption and scalable commercial impact.”\u00a0<\/p>\n

Rob\u00a0Solomon, Chief\u00a0Executive Officer\u00a0of H55, added:\u00a0<\/p>\n

“This\u00a0achievement\u00a0marks\u00a0a\u00a0structural\u00a0inflection\u00a0point\u00a0for\u00a0electric\u00a0aviation.\u00a0By\u00a0completing\u00a0the\u00a0first\u00a0<\/p>\n

EASA-agreed\u00a0battery module\u00a0test\u00a0campaign,\u00a0H55\u00a0has\u00a0addressed\u00a0the\u00a0most\u00a0critical technical\u00a0bottleneck on the certification path, materially reducing risk for aircraft manufacturers, operators, insurers, and investors.\u00a0<\/p>\n

By\u00a0providing\u00a0monitoring,\u00a0active\u00a0and\u00a0passive\u00a0protections\u00a0of\u00a0every\u00a0individual\u00a0cell,\u00a0H55\u00a0transforms\u00a0the propulsion\u00a0battery\u00a0from\u00a0a\u00a0‘black box’\u00a0of\u00a0latent risk\u00a0into\u00a0an\u00a0actuarially\u00a0transparent\u00a0asset,\u00a0establishing cell-level monitoring as the non-negotiable threshold for both regulatory type certification and fleet insurability.\u00a0What’s most exciting, is the engine-like business model this enables for H55.\u00a0<\/p>\n

In\u00a0parallel, through\u00a0a\u00a0joint multi-authority\u00a0Certification\u00a0Management\u00a0Team,\u00a0EASA\u00a0and\u00a0the\u00a0U.S.\u00a0Federal Aviation Administration (FAA) have committed to mutual recognition of agreed means of compliance for\u00a0ongoing\u00a0programs. Test\u00a0results\u00a0will\u00a0be\u00a0transferred\u00a0to\u00a0the\u00a0FAA,\u00a0providing\u00a0a\u00a0basis\u00a0for\u00a0supporting\u00a0and accelerating H55’s U.S.\u00a0certification activities and market presence.”\u00a0<\/p>\n

S\u00e9bastien\u00a0Aymon-Demont,\u00a0Co-Founder\u00a0and\u00a0Chief Technology\u00a0Officer\u00a0of\u00a0H55,\u00a0commented on battery module architecture and the cell level approach\u00a0<\/p>\n

“By\u00a0designing protection,\u00a0monitoring,\u00a0and\u00a0mitigation\u00a0directly at\u00a0cell\u00a0level,\u00a0rather\u00a0than\u00a0relying\u00a0on\u00a0pack-level assumptions, we have built a fundamentally different Energy Storage System.\u00a0This cell-level architecture\u00a0not\u00a0only\u00a0enables effective\u00a0protection\u00a0at\u00a0the\u00a0point of\u00a0origin,\u00a0but\u00a0also\u00a0allows us\u00a0to\u00a0optimise battery efficiency, performance, and long-term reliability \u2014 all of which are essential for certifiable electric aviation.”\u00a0<\/p>\n

About\u00a0the\u00a0Test\u00a0Campaign\u00a0<\/p>\n

To execute this campaign, H55 produced more than 100 test articles drawn from its approved and audited product configuration.\u00a0The six-month effort covered environmental, safety, functional, and performance conditions under worst-case failure modes, including authority-witnessed thermal runaway\u00a0tests\u00a0without\u00a0propagation.\u00a0Collectively,\u00a0these\u00a0results confirm\u00a0readiness\u00a0for\u00a0certification\u00a0and industrial deployment, including:\u00a0<\/p>\n

Clearing\u00a0the\u00a0Certification\u00a0Bottleneck\u00a0to\u00a0Enable\u00a0Scalable Commercialisation\u00a0<\/p>\n

Electric aviation scales on certification.\u00a0By completing this regulator-approved propulsion battery module test campaign, H55 has materially reduced the primary constraint that determines which electric\u00a0aviation\u00a0technologies\u00a0can\u00a0commercialise.\u00a0Formal demonstration\u00a0of\u00a0containment\u00a0under\u00a0worst-case failure scenarios materially reduces regulatory and insurance exposure, unlocking repeatable, certifiable deployment across aircraft programs while ensuring aircraft-level safety.\u00a0<\/p>\n

With this achievement, H55 is transitioning from validation to scale.\u00a0A single, certifiable Energy Storage System architecture can now be deployed across multiple platforms, allowing certification evidence\u00a0to\u00a0compound\u00a0as\u00a0revenue\u00a0potential\u00a0expands\u00a0without\u00a0proportional\u00a0increases\u00a0in\u00a0development cost, supporting repeatable deployment across fleets and aircraft lifecycles rather than one-off programme deliveries.\u00a0With propulsion battery-module certification risk now addressed, electric aviation moves from speculative development to a certifiable industrial category \u2014 reshaping how programs are evaluated, financed, and insured.\u00a0<\/p>\n

About H55\u00a0<\/p>\n

H55 is a Swiss-based company specialising in certified electric propulsion and certification-grade energy storage systems for aviation.\u00a0The company enables electric aviation to scale by transforming commercial\u00a0lithium\u00a0cells\u00a0into\u00a0aviation-safe\u00a0Energy\u00a0Storage\u00a0Systems that\u00a0regulators\u00a0approve, insurers underwrite, and OEMs can deploy repeatedly as a certified propulsion platform across aircraft programs. This is achieved through independent cell characterisation, rigorous incoming screening, redundant safety architectures, and regulator-aligned testing designed around worst-case failure scenarios.\u00a0<\/p>\n

Founded\u00a0as\u00a0the\u00a0technological\u00a0legacy\u00a0of\u00a0the\u00a0Solar\u00a0Impulse program,\u00a0H55\u00a0builds\u00a0on\u00a0more\u00a0than\u00a0two decades of hands-on electric aviation experience.\u00a0The company has designed, built, and flown multiple electric aircraft and accumulated more than 2,000 hours of fully electric flight with zero battery-related incidents\u2014providing the operational depth required to execute certification-grade programs, not merely comply with them.\u00a0<\/p>\n

Certification-Grade\u00a0Battery\u00a0Module\u00a0Safety Test\u00a0Campaign\u00a0<\/p>\n

Since 2017, H55 has maintained continuous engagement with global regulatory authorities to establish a certification-grade framework for propulsion batteries.\u00a0Through this sustained interaction, H55\u00a0has\u00a0developed an\u00a0evidence-based,\u00a0regulator-aligned\u00a0understanding\u00a0of\u00a0propulsion\u00a0battery\u00a0failure behaviour, grounded in systematic risk evaluation across the full operational lifecycle.\u00a0<\/p>\n

This understanding was developed through the design, construction, and flight operation of fully electric aircraft, supported by extensive development and certification test activities.\u00a0Rather than adapting\u00a0assumptions\u00a0from\u00a0adjacent\u00a0industries,\u00a0H55\u00a0deliberately\u00a0built\u00a0its\u00a0own\u00a0engineering\u00a0capability, production systems, and test infrastructure, enabling direct, regulator-approved demonstration of compliance.\u00a0<\/p>\n

Regulatory\u00a0Foundations\u00a0<\/p>\n

H55\u00a0holds\u00a0Design Organisation\u00a0Approval\u00a0(DOA), confirming\u00a0the\u00a0organisational\u00a0competence,\u00a0qualified personnel, and technical capability required to certify electric propulsion systems.\u00a0<\/p>\n

H55\u00a0also\u00a0holds\u00a0Production\u00a0Organisation\u00a0Approval\u00a0(POA),\u00a0validating\u00a0robust\u00a0production\u00a0and\u00a0quality systems capable of manufacturing fully conforming aerospace products.\u00a0<\/p>\n

Battery Cell Characterisation\u00a0and Risk\u00a0Definition\u00a0<\/p>\n

H55 has invested substantial resources in battery cell characterisation, generating proprietary datasets\u00a0that\u00a0enable\u00a0aerospace-grade\u00a0cell\u00a0qualification,\u00a0validation\u00a0of\u00a0all\u00a0plausible failure\u00a0modes,\u00a0and definition of worst-case scenarios formally accepted by authorities.\u00a0<\/p>\n

Summary\u00a0of\u00a0Key Outcomes\u00a0<\/p>\n

With battery-module certification risk now addressed, electric aviation transitions from experimentation to scalable, certifiable commercial deployment.\u00a0<\/p>\n
