In a move that marks significant progress on the flightpath to decarbonised air travel, Gloucestershire's green trailblazer ZeroAvia is to reach out to "clean-flight" aviation OEMs by offering them its electric and hydrogen avation components.

The Anglo-American disruptor, which has major R&D operations at Kemble Airfield in Gloucestershire, said the marketing move comes in reaction to "strong OEM interest" in its leading fuel cell, power electronics, compressor and electric motor technology.

Key to implementation will be the firm's New Propulsion Center of Excellence manufacturing plant, which is in Everett, Washington State, and lies about 25 miles north of Seattle. The site is pivotal to ZeroAvia's fuel cell system production.

Val Miftakhov, ZeroAvia founder and CEO, said: "Today we set forth plans that detail how we are going to bring our engines to market for commercial aircraft as well as the additional market potential in components generated by our pursuit of aerospace-applicable fuel cell and electric propulsion technologies."

The move aims to secure as much market share for commercial aviation propulsion systems as possible "as this will enhance shareholder value and ensure we deliver in tackling climate impact in the sector", he added.

He said: "While the market for our powertrains is thousands of engines across commercial aircraft, there will be other applications that are not strategically aligned with our full engine offering, but where our technologies can play a major role in the supply chain for other OEMs.

"And with the opening of the new facility today, we are also able to show ZeroAvia's growth from ambitious startup into a clean aerospace manufacturing powerhouse, with a production site officially opened in Everett. The future is bright for clean flight, Washington State!"

The move allows ZeroAvia to build upon what is now seen as a multi-billion pound market for its hydrogen-electric powertrain family, while it also aims to maximise the company's investment in R&D, as well as furthering the company's impact on reducing environmental harm from aviation.

With the certification work for the ZA600 engine for up to 20 seat aircraft underway, and the underpinning technology for the ZA2000 engine for up to 90 seat aircraft in advanced development, ZeroAvia says its component market research spies significant opportunity in:

● Advanced electric motors for aviation, including a 660 kW max-power direct-drive motor capable of speeds up to 2,200 rpm, and the HyperCore 900kW modular motor capable of speeds up to 20,000 rpm.

● Silicon carbide inverters - The 200kW continuous power bidirectional inverter design offers a power density above 20 kW/kg and is available in single (225kW peak / 200kW continuous) and dual (450kW peak / 400kW continuous) configurations. The inverters are designed and produced following aerospace standards, allowing a high-power density and reduced weight with advanced thermal management technologies and integration to enable reliable high performance for high altitude and engine compartment location.

● Low temperature Proton Exchange Membrane (LT-PEM) fuel cell configurations (in partnership with PowerCell) - ZeroAvia's SuperStack Flex architecture is a customizable 100-400kW fuel cell power generation platform designed to meet a range of different aerospace power, performance, and packaging requirements, while maintaining exceptional pressure, mass flow rate, humidity, and temperature control.

● High temperature PEM (HT-PEM) fuel cell stacks and full power generation systems - ZeroAvia's High-Temperature Proton Exchange Membrane (HTPEM) fuel cell stack is a turbo-air cooled modular system which offers up to 3.5 kW/kg specific power, supporting a variety of traditional aviation and VTOL applications.

The company added that it is now in "active discussions on potential deals with a number of companies working on electric and hydrogen aviation innovations".

For the opening of the new propulsion center of excellence at Paine Field in Everett, a ribbon-cutting ceremony was attended by Washington State Governor Jay Inslee and US Representatives Rick Larsen and Suzan DelBene.
