ZeroAvia develops powertrain for Grand Caravan
The Grand Caravan is on track to be one of the first airframes operating commercial passenger and cargo services with a hydrogen-electric powertrain. Textron will provide data, engineering and certification support.
ZeroAvia will develop a hydrogen-electric powertrain for the Grand Caravan.

ZeroAvia has entered into a non-exclusive joint development agreement with Textron Aviation to support development of its hydrogen-electric, zero-emission powertrains for the Cessna Grand Caravan (208B) aircraft. ZeroAvia will obtain a supplemental type certificate (STC) to retrofit the Grand Caravan single engine utility turboprop with the ZA600 zero-emission powertrain, targeting commercial passenger and cargo operators.

The Cessna Grand Caravan is designed and manufactured by Textron Aviation. Its high-wing design makes it a strong candidate for mounting hydrogen fuel tanks under the wings, ensuring operators can maintain seat capacity or cargo space, while transitioning to true zero emission propulsion systems. ZeroAvia will develop its ZA600 powertrain system with data, engineering and certification support provided by Textron Aviation. ZeroAvia aims to obtain certification for the 600kW powertrain as early as 2025, enabling customers to operate zero-emission flights.

The Cessna Grand Caravan platform has seen more than 2,400 aircraft delivered worldwide since its introduction, representing enormous potential for a shift to clean propulsion. ZeroAvia already has several agreements with operators and lessors in relation to conversions.

ZeroAvia founder and CEO Val Miftakhov says: “The famous Cessna Grand Caravan is on track to be one of the first airframes operating commercial services, both cargo and passenger, with hydrogen-electric, zero-emission engines. We applaud the visionary leadership of Textron Aviation in joining us to help transform a much-loved mainstay of sub-regional aviation into a symbol of sustainable transformation in aviation.”

This agreement with Textron adds to significant prior commitments from other aircraft original equipment manufacturers and operators to ZeroAvia's powertrain technology over the course of the last few months. ZeroAvia is already well advanced in retrofitting its system into a 19 seat Dornier 228 aircraft at its R&D location at Cotswold airport in the UK, with first test flights anticipated over the next few weeks. The company is actively developing the market for its ZA600 product with different nine to 19 seat airframes, while concurrently developing its ZA2000, two to five MW engine class for 40 to 80 seat aircraft with an entry into service target of 2027.

The company's hydrogen-electric powertrains use fuel cells to generate electricity, which power electric motors to then turn propellers. Hydrogen-electric systems produce only water vapour and at temperatures that enable the management of contrail impact.

ZeroAvia's work in developing its 600kW system through to a certifiable design is part of the HyFlyer II project, supported by the UK Government's Department for Business, Energy and Industrial Strategy (BEIS), Aerospace Technology Institute (ATI) and Innovate UK through the ATI Programme.
