HAL Collaborating with ZeroAvia to Develop Hydrogen Powertrain for Dornier 228 Zero-Emission Aircraft

  • HAL & ZeroAvia will develop a Supplemental Type Certificate (STC) to incorporate a 600KW hydrogen-electric powertrain system into a Dornier 228 aircraft.
  • HAL intends to offer retrofits to existing Dornier & Hindustan-228 Aircraft and line fit new manufactured Dornier & Hindustan-228 Aircraft.
  • The aircraft will use the ZeroAvia ZA600, the company's first commercial type powertrain platform, capable of producing up to 600 kW without emissions.

ZeroAvia, the leading innovator in zero emission aviation, has announced a development collaboration with the Indian state-owned aerospace & defence company Hindustan Aeronautics Ltd (HAL) for a hydrogen-electric powertrain capable of flying the 19 seat Dornier 228 aircraft up to 500 NM.

HAL intends to work with ZeroAvia to develop a Supplemental Type Certificate (STC) to allow retrofit of existing airframes for both Indian military and worldwide operators. HAL also intends to continue to build new aircraft with additional FAA approval, designated Hindustan-228, creating the opportunity to incorporate ZeroAvia’s ZA600 zero-emission engines. Additionally, HAL and ZeroAvia engineers will integrate ZeroAvia’s ZA600 hydrogen-electric powertrain into the Dornier 228 airframe. ZeroAvia will work closely with HAL and aircraft regulators during this project to ensure that aircraft meets both safety and operational requirements.

Approximately 270 Dornier 228 aircraft have been manufactured globally, with 242 currently in service. The production line of Do-228 aircraft is operational at HAL, India (Transport Aircraft Division, Kanpur, UP, India).

R Madhavan, CMD, HAL, said: “HAL is committed to contributing to the protection and better development of the environment. This MoU with ZeroAvia has the potential to pave the way for zero emission regional connectivity. We are looking forward to steering and supporting sustainable and environmentally friendly aviation in India and the world”

Apurba Roy, General Manager, HAL’s Transport Aircraft Division said: “HAL is committed to the ongoing development of the Dornier 228 aircraft, and it is critical to offer it as a zero-emission platform, including the conversion of the existing fleet. We are honored to partner with ZeroAvia, who in our view is leading the way in the development of innovative solutions to deliver practical zero-emission aircraft”

HAL and ZeroAvia engineers will integrate ZeroAvia’s ZA600 hydrogen-electric powertrain into the Dornier 228 airframe. HAL signed a technology transfer agreement with Dornier in 1983 and has produced main sub-assemblies and over 150 aircraft, including those operated by the Indian Military.

Val Miftakhov, CEO and founder, ZeroAvia said: “We are pleased to be working with HAL to deliver zero-emission aircraft to market in the shortest time frame. HAL has a long experience with the Dornier 228 aircraft, and since this is also our flight test aircraft, this collaboration helps us achieve our goal of certifying our engine whilst providing an STC solution to operators worldwide,”

A Dornier 228 based at ZeroAvia’s facility at Cotswold Airport in the UK is being used as the dedicated development platform for the HyFlyer II project, which is progressing the R&D required for the ZA600 powertrain for 19-seat aircraft. ZeroAvia recently successfully ground-tested its 600kW powertrain and will begin flight testing using its Dornier 228 in the coming months to achieve certification and entry into commercial service in 2024.

HyFlyer II is part-funded by the ATI Programme, which is supported by the UK’s Aerospace Technology Institute, Innovate UK and the Department for Business, Energy and Industrial Strategy.

In late October 2021, ZeroAvia and Rotterdam The Hague Airport (RTHA) announced a partnership with the aim of establishing the world’s first hydrogen-electric international passenger route, using 19-seat aircraft such as HAL’s 228.
