Leeham News and Analysis
There's more to real news than a news release.
Bjorn’s Corner: Air Transport’s route to 2050. Part 11.
By Bjorn Fehrm
February 28, 2025, ©. Leeham News: We do a Corner series about the state of developments to replace or improve hydrocarbon propulsion concepts for Air Transport. We try to understand why the development has been slow.
Last week, we discussed the fact that Airbus has moved its hydrogen-fueled ZEROe aircraft into the 2040s and that it will be fuel cell based. It’s a bit of an irony that Pratt &Whitney announced major news for the alternative hydrogen burn alternative four weeks before. Let’s dissect what Pratt & Whitney announced.

February 21, 2025, ©. Leeham News: We do a Corner series about the state of developments to replace or improve hydrocarbon propulsion concepts for Air Transport. We try to understand why the development has been slow.
Last week, we reviewed the present fallout of lower emission projects that have not reached their goals and where investors, therefore, have decided not to invest further.
There is a well-known project failing every month at the present pace. Some recent ones: Universal Hydrogen’s ATR conversions, Volocopter and Lilium’s bankruptcies, Airbus freezing the CityAirbus eVTOL (Figure 1) and pushing out the ZEROe hydrogen airliner, hibernation of the Alice battery aircraft, etc. There will probably be more in the coming months.
Airbus 2024 results: “A decent year in a challenging environment”.
By Bjorn Fehrm
February 20, 2025, © Leeham News in Toulouse: The headline uses the words of Airbus CEO Guillame Faury when he opened the presentation of Airbus 2024 results in Toulouse today. It was a session where Faury and the CFO Thomas Toepfer put in an effort to let all present international journalists and their online colleagues ask all questions and deliver honest answers.
On the business-as-usual side, the company delivered 766 aircraft, which was within the guidance, after a deep grab effort in 4Q, leading to low deliveries for 1Q2025. EBIT at €5.4bn and Free Cash Flow at €4.5bn were also within guidance.
In general, the Commercial airplane side was fighting specific supply problems during 2024, which might limit the ramp-up of A350s and A220s going forward, more of which below. Helicopters have now recovered from challenging times and delivered a solid result. Defense and Space are strong in Air Power (fighters, etc.), given the tense European situation, with Space going through restructuring, which might include mergers with other European space players.
The real news was the reasons for pausing the CityAirbus eVTOL program, according to Faury, “not only because batteries were not where they should have been but also due to the lack of a market for this type of transportation.” As the world’s largest supplier of helicopters, Airbus is a credible source for such a lack of market statement.
Faury also detailed what is happening on the Hydrogen side. Due to slower-than-expected progress in Green Hydrogen production build-up, deployment of preparatory Ground Support Equipment (GSE), and Transportation using hydrogen at the airports in their H2 partner network, Airbus has decided to push out the entry into service of a “commercially viable hydrogen aircraft” by five to ten years.
However, said Faury, it has made progress. “We have reached TRL 3 for the tecnobricks, which has enabled us to select the Fuel Cell path as the preferred way forward. This means these activities are continued at the present level or even intensified, but it also means other paths (read Hydrogen burn) are ramped down. Overall, it means a decrease in R&D spending for Hydrogen activities in the coming years.”

February 7, 2025, ©. Leeham News: We do a Corner series about the state of developments to replace or improve hydrocarbon propulsion concepts for Air Transport. We try to understand why the development has been slow.
We have covered the progress of battery-based aircraft and hybrids, where the last Corner was about the most sensible hybrids, the mild hybrids. Now, we turn to hydrogen-fueled alternatives.

We have covered why the technical progress of battery-based aircraft has been slow. Now we look at what type of missions it can do this decade and beyond and why the limitations.

Merry Christmas 2024 and Happy New Year 2025
Leeham News is taking the holidays off. Unless there is some huge breaking news before, we will return on Jan. 6, 2025.

Bjorn’s Corner: Air Transport’s route to 2050. Part 1.
By Bjorn Fehrm
October 18, 2024, ©. Leeham News: In Corners over the last years, we have covered new airliner technology and engine developments that would apply to the next-generation airliners in the largest segment of the market, the single-aisle segment, or as we like to call it, the Heart of the Market segment, as it’s not sure it will be a single-aisle aircraft.
The series has assumed this generation will be hydrocarbon-fueled gas turbine-propelled airplanes. Therefore, it has not covered the current state of alternatives to gas turbine-based hydrocarbon propulsion.
We will cover this now. We are now 10 years into the discussions and work of reducing Air Transport’s reliance on hydrocarbon fuels, which started in earnest when Airbus flew the E-Fan battery-electric aircraft at the Farnborough Air Show in 2014, Figure 1.
How are we doing?

Bjorn’s Corner: New engine development. Part 27. Long developments
October 4, 2024, ©. Leeham News: We do an article series about engine development and why it has longer timelines than airframe development. It also carries larger risks of product maturity problems when it enters service than the airframe of an airliner.
We looked at engine technologies and why several are challenging to bring to a mature technical state. Then, we compared previous engine developments with the present generation. Memory is short. What we could see is that previous generations of engines carried larger reliability and durability problems than the present generation engines.
Now, we discuss the development timelines for key engine versus airframe developments.

Bjorn’s Corner: New engine development. Part 26. New versus old, Trent 1000 vs. XWB
By Bjorn Fehrm
September 27, 2024, ©. Leeham News: We do an article series about engine development and why it has longer timelines than airframe development. It also carries larger risks of product maturity problems when it enters service than the airframe of an airliner.
In our look at examples of recent developments with problems and these put in a historical perspective, looking at the reliability and durability of its predecessor we compare the Rolls-Royce Trent 1000 for the Boeing 787 to the Trent XWB for the Airbus A350.

Embraer versus Boeing JV arbitration decision results in $150m cash payment
By the Leeham News team
September 16, 2024, © Leeham News: Embraer issued a short investor release today stating that the arbitration was concluded regarding Boeing’s unilateral termination of the agreement of a Commercial Aircraft Joint Venture and a partnership regarding the C-390 aircraft. Boeing did the M&A termination in April 2020.
The resu
lt is that Embraer will receive a $150 m cash payment from Boeing. The payment is below the market expectations, which were around $300m to cover the Embraer carve out and carve in costs. The issue of the Boeing merger and its effects on Embraer is now history, which is positive even though Boeing’s damages payment was lower than expected.
Embraer will most likely use the cash injection to lower its net debt, which is already at a low $1.3bn and has a leverage to EBITDA of 2.0.
It was in July 2018 that Embraer announced it would sell 80% of its Commercial Aviation business, then valued at a 100% value of $5.25bn to Boeing. The Master Transaction Agreement was signed in January 2019. It included a joint venture for marketing the C-390 Millenium multi-mission military cargo jet.
