KLM and ZeroAvia Plan Zero-Emission Demonstration Flight Using Liquid Hydrogen

KLM and ZeroAvia Plan Zero-Emission Demonstration Flight Using Liquid Hydrogen

ZeroAvia and KLM Royal Dutch Airlines today announced that they will work towards a demonstration flight using ZeroAvia’s ZA2000 zero-emission, hydrogen-electric engines for large regional turboprop.

Hydrogen-electric engines use hydrogen in fuel cells to generate electricity, which is then used to power electric motors to turn the aircraft’s propellers. The only emission is low-temperature water vapour, with studies therefore estimating an up to 90% reduction in climate impact when compared with typical kerosene-fueled flights.[1] 

As a first major target milestone, the companies aim to conduct an initial A-to-B flight demonstration between two airport locations in 2026. As well as identifying the optimal airport pair, immediate workstreams will be working towards regulatory permits to fly and ensuring supply of liquid hydrogen fuel and putting in place the supporting infrastructure for aircraft fueling. 

Airbus partners with Avolon to explore future of hydrogen aviation

Airbus has announced a new partnership with aircraft lessor, Avolon, to study the potential of hydrogen-powered aircraft, marking the very first collaboration of the ZEROe Project with an operating lessor.

Announced at the Farnborough Airshow, Airbus and Avolon will investigate how future hydrogen-powered aircraft could be financed and commercialised, and how they might be supported by the leasing business model.

Airbus is putting significant resources into exploring how the industry can introduce hydrogen-powered aircraft and how it works on the ground with airports and airlines. The development of a viable hydrogen ecosystem is a key enabler of the industry’s goal to reach near zero emissions.

Paul Geaney, President and Chief Commercial Officer, Avolon, commented, “Joining the ZEROe Project is another step in Avolon’s sustainability journey and we look forward to building on our long-standing partnership with Airbus to consider how the next generation of aircraft will be financed and commercialised. It will take a wide ecosystem of contributors to overcome the challenges of hydrogen powered commercial flight, and Airbus is playing a crucial role in bringing partners together. While we continue to focus on supporting our customers in modernising their fleets with lower emissions aircraft, it is also vital we look beyond that at what can further drive our industry’s decarbonisation.”

Airbus Vice President ZEROe Project, Glenn Llewellyn, said, “There is real value in bringing together industry players to help solve the challenges facing aviation. We know we can’t solve decarbonisation alone and welcome Avolon’s expertise and worldwide leadership in the aircraft leasing business. Working together to consider how the transition can be commercialised and financed for airline customers is crucial to success.”

Airbus welcomes London Gatwick to global hydrogen hub network

Airbus has teamed up with London Gatwick, easyJet and Air Products, the world’s largest hydrogen supplier, to expand hydrogen capability and infrastructure in the UK as the manufacturer moves closer to its target of getting a hydrogen-powered aircraft in the sky by 2035. 

Setting up the right infrastructure is key to enabling hydrogen flight and this partnership is yet another step towards making this a reality in the UK. 

Under Airbus’ Hydrogen Hubs at Airport's framework, the scope of work covers liquid hydrogen supply and storage at the airport, refuelling and ground handling of hydrogen aircraft, as well as the exploration of other, shorter-term opportunities for using hydrogen at London Gatwick. 

Because early hydrogen-powered aircraft will initially focus on short to medium-haul routes, London Gatwick’s position as the UK’s leading hub for these services, along with easyJet’s operational insight as a short-haul carrier, makes this the ideal testbed for R&D into critical support infrastructure. This collaboration between Airbus, London Gatwick, easyJet and Air Products will serve as a powerful statement of commitment to making hydrogen-powered flight a reality by 2035. 

Airbus Vice President ZEROe Project Glenn Llewellyn said: “Our licence to operate hinges on finding better ways to fly. We know hydrogen has the versatility to be an excellent fuel source for decarbonising the industry. We’ve set ambitious targets to fly on hydrogen by 2035 and this technology needs to be supported by reliable and tested infrastructure. Sharing knowledge and best practices at airports will be critical for building the right hydrogen ecosystem around the world and we look forward to working with all consortium members to develop the support for the technology and end-to-end hydrogen supply chain that will power future flight.”

American Airlines commits to conditional purchase of 100 ZeroAvia hydrogen-powered engines

 American Airlines today announced that it has entered into a conditional purchase agreement with clean aviation innovator ZeroAvia for 100 hydrogen-electric engines intended to power regional jet aircraft with zero inflight emissions save for water vapor.

In addition, American has increased its investment in ZeroAvia. American made its first investment in ZeroAvia in 2022 and has also now participated in the company’s Series C financing round. The engine agreement follows the Memorandum of Understanding the companies announced in 2022.

ZeroAvia is developing hydrogen-electric (fuel cell-powered) engines for commercial aircraft, which offer the potential for close to zero inflight emissions. The company is flight testing a prototype for a 20-seat plane and designing an engine for larger aircraft such as the Bombardier CRJ700, which American operates on certain regional routes.

“Advancing the transition of commercial aviation to a low-carbon future requires investments in promising technologies, including alternate forms of propulsion,” said American’s CEO Robert Isom. “This announcement will help accelerate the development of technologies needed to power our industry and uphold our commitment to make American a sustainable airline so we can continue to deliver for customers for decades to come.”

Ground-breaking airport hydrogen trial next critical step on journey to achieving zero emission aviation

• Project Acorn is the first airside hydrogen refuelling trial ever to take place at a major UK airport
• Hydrogen has been used to refuel and power critical parts of easyJet’s ground operation at Bristol Airport, demonstrating hydrogen can be safely and reliably used in place of other fuels in an airport
• The data and insight gathered will be used to create the first ever safety guidance and inform the creation of the regulatory framework
• Critically, the UK Civil Aviation Authority (CAA) has played an active role in the trial as an independent reviewer of the safety case
• The trial also aims to accelerate the use of hydrogen in aviation and across other industries

A ground-breaking airside hydrogen refuelling trial, led by easyJet and supported by several cross-industry partners, has been successfully completed at Bristol Airport – the first airport trial of its kind at a major UK airport.

Hydrogen was used to refuel and power ground support equipment (GSE) – specifically, baggage tractors – servicing easyJet passenger aircraft. Conducted as part of the airline’s daily operations, the trial demonstrates that the gas can be safely and reliably used to refuel ground equipment in the busy, live airport environment.

The trial, dubbed Project Acorn, was in development for over a year and involved many other leading organisations from across aviation, engineering, logistics and academia. These include Cranfield Aerospace Solutions, Cranfield University, Connected Places Catapult (CPC), DHL Supply Chain, Fuel Cell Systems, the IAAPS research institute, Jacobs, Mulag and TCR.

The group intends to use the outputs of the trial to help develop industry best practice standards, provide guidance to airports, airlines, local authorities and regulators on required infrastructure changes, and support the development of a regulatory framework for hydrogen’s use on an airfield – standards which, due to hydrogen’s nascency in aviation, do not currently exist.

The data and insights gathered will also feed into research that groups like Hydrogen in Aviation (HIA)* are conducting to ensure UK infrastructure, regulatory and policy changes keep pace with the technological developments in carbon-emission free flying. It also supports the work and ambitions of other bodies such as Hydrogen South West (HSW) and the Hydrogen Innovation Initiative (HII), the latter having also co-funded the project.

David Morgan, Chief Operating Officer at easyJet, said:   “It’s without doubt that hydrogen will be an important fuel of the future for short-haul aviation, as demonstrated by the rate of innovation we’re seeing.

While the technology is advancing at an exciting pace, as hydrogen isn’t used in commercial aviation today, there is currently no regulatory guidance in place on how it can and should be used, and so trials like this are very important in building the safety case and providing critical data and insight to inform the development of the industry’s first regulatory framework. This will ensure regulation not only keeps pace with innovation, but importantly also supports the industry in meeting its decarbonisation targets by 2050.”

Tim Johnson, Director for Strategy, Policy and Communications at the Civil Aviation Authority, comments:

“Projects such as this are cornerstones of our commitment to support innovation and decarbonisation in the industry.

This trial will serve as the basis of a White Paper which we will also be contributing to, as well as allow for the creation of further safety guidance and regulatory standards for the use of hydrogen in aviation. 

We look forward to helping nurture this seed of the future greener aviation sector as it continues to grow.”

The Hydrogen in Aviation alliance is calling for a comprehensive industrial strategy for aviation to ensure the UK is a global leader in the development of  hydrogen aviation

The report sets out how to ensure the country has the right conditions for the technological development, regulation, infrastructure, financial framework and hydrogen supply that will be needed for hydrogen aviation

HIA’s ultimate goal is to ensure hydrogen-powered flights become a reality to help preserve the huge social and economic benefits that aviation brings

The Alliance, formed of major players across the aviation, manufacturing and renewable energy sectors, see hydrogen as one of the key tools for the decarbonisation of aviation, and key to creating new jobs and supporting the sector’s long term sustainable future

The Hydrogen in Aviation alliance (HIA), formed of easyJet, Rolls-Royce, Airbus, Ørsted, GKN Aerospace, Bristol Airport and ZeroAvia, has today released its Milestone Delivery Report – outlining the steps and timeline the UK Government and industry needs to follow to secure its position as a global leader in hydrogen-powered aviation.

The UK is home to many world-first advances in hydrogen-powered aircraft technology, from hydrogen engine testing to the first flights of hydrogen-fuelled planes – making it well placed to be a leader in hydrogen aviation. This would secure substantial economic, employment and sustainability benefits. To realise these benefits we need an industrial strategy for the sector focussed on these long term opportunities.

The UK will need to secure massive increases in hydrogen supply. This will involve the accelerated deployment of renewable and low carbon energy generation and significant investment in hydrogen infrastructure and skills.

In order to achieve this, HIA’s new Milestone Delivery Report – which has been shaped by accurate aviation demand figures and other critical industry data – outlines specific steps that need to be taken by industry, government and regulators to equip the UK with everything it needs to be a leader in the field of hydrogen-powered aviation.

Johan Lundgren, CEO of easyJet and first Chair of HIA, said:  “It’s without doubt that the UK is well placed to be a global leader in hydrogen – but the opportunity will be gone if we do not act now to build on all the great work that has already been done.

“The breakthroughs in hydrogen-powered technology happening across the UK are truly astonishing but these advances will be inconsequential if we fail to complement them with the appropriate skills, infrastructure, investment and regulation needed to support hydrogen aviation.

“HIA’s Milestone Delivery Report outlines the critical steps and the timeframe needed to do this and if followed, not only will it create significant wealth, jobs and prosperity across industry and across the UK, it will be a vital component in decarbonising the aviation sector.”

Mark Bentall, Head of Research & Technology at Airbus, said:  “Technology is already unlocking the potential of hydrogen as a new fuel and Airbus is firmly focused on getting a hydrogen powered aircraft in the air by 2035. Beyond the aircraft, we have to prepare people, policy and infrastructure to build a world-leading hydrogen aviation economy in the UK. This report gives us the blueprint for making it happen, so now is the time to follow through.”

Universal Hydrogen gets experimental airworthiness certificate by the Federal Aviation Administration and completes first taxi tests....

Universal Hydrogen Co., whose mission is to make hydrogen aviation a near-term reality, today announced it was granted a special airworthiness certificate in the experimental category by the Federal Aviation Administration (FAA) to proceed with the first flight of its hydrogen-powered regional aircraft. The company also released video footage of successful first taxi tests of the aircraft, designed to evaluate ground handling qualities and the performance of the fuel-cell electric powertrain at low power settings and airspeeds.

The Dash 8-300 flying testbed has a megawatt-class hydrogen fuel cell powertrain installed in one of its nacelles. The powertrain is in a configuration that closely resembles the company’s first product—a conversion kit for ATR 72-600 regional airliners—which is expected to be certified and in commercial passenger service starting in 2025. Notably, Universal Hydrogen’s powertrain does not utilize a hybrid battery architecture—a major innovation—with all of the power transmitted directly from the fuel cells to the electric motor, significantly decreasing weight and lifecycle cost.

Rolls-Royce and easyJet set aviation world first successful hydrogen engine test run

Rolls-Royce and easyJet today confirmed they have set a new aviation milestone with the world’s first run of a modern aero engine on hydrogen.

The ground test was conducted on an early concept demonstrator using green hydrogen created by wind and tidal power. It marks a major step towards proving that hydrogen could be a zero-carbon aviation fuel of the future and is a key proof point in the decarbonisation strategies of both Rolls-Royce and easyJet.

Both companies have set out to prove that hydrogen can safely and efficiently deliver power for civil aero engines and are already planning a second set of tests, with a longer-term ambition to carry out flight tests.

The test took place at an outdoor test facility at MoD Boscombe Down, UK using a converted Rolls-Royce AE 2100-A regional aircraft engine. Green hydrogen for the tests was supplied by EMEC (European Marine Energy Centre), generated using renewable energy at their hydrogen production and tidal test facility on Eday in the Orkney Islands, UK.

Grazia Vittadini, Chief Technology Officer, Rolls-Royce, said: “The success of this hydrogen test is an exciting milestone. We only announced our partnership with easyJet in July and we are already off to an incredible start with this landmark achievement. We are pushing the boundaries to discover the zero carbon possibilities of hydrogen, which could help reshape the future of flight.”

Johan Lundgren, CEO of easyJet, said: “This is a real success for our partnership team. We are committed to continuing to support this ground-breaking research because hydrogen offers great possibilities for a range of aircraft, including easyJet-sized aircraft. That will be a huge step forward in meeting the challenge of net zero by 2050.”

Following analysis of this early concept ground test, the partnership plans a series of further rig tests leading up to a full-scale ground test of a Rolls-Royce Pearl 15 jet engine.

The partnership is inspired by the global, UN-backed Race to Zero campaign that both companies have signed up to, committing to achieve net zero carbon emissions by 2050.
