September 25, 2020, ©. Leeham News: In our series on Hydrogen as an energy store for airliners, we look at the three hydrogen-based concept aircraft Airbus presented this week.
They are called ZEROe and are concepts and not products, but their design tells us a lot about where Airbus is with its studies and how the hydrogen demonstrator aircraft might look like come 2026-2028.

Aug. 31, 2020, (c) Leeham News: European regionals face far greater challenges than Covid and, sadly, much of what is happening to the industry is beyond its control. The result is similar to failures seen in the U.S. Flybe’s recent loss resulted from pre-Covid problems which also led to the pre-Covid failures of such airlines as Flybmi and Cobalt.
The failures illustrate, however, the three reasons why European regionals are so fragile – low-cost competition, geography, and challenging government policy.
July 31, 2020, ©. Leeham News: In our series on Hydrogen as an energy store for airliner use we begin by looking at the needed ecosystem that can produce and distribute Hydrogen.
When I was skeptical about hydrogen as a means to propel our airliners three years ago, the main problem was the lack of this ecosystem. That year, in 2017, 13 transport and energy companies formed the Hydrogen Council, to create this ecosystem. Today the council has 81 members, with 22 joining in the last year, Figure 1. The list reads as Who’s Who in the transport and energy sector.

June 10, 2020, ©. Leeham News: France presented a 15 billion Euro support plan for the French aeronautical industry yesterday, to help the industry overcome the effects of the COVID-19 pandemic.
The plan has three focus areas:
April 10, 2020, ©. Leeham News: We have since December 13, discussed why e in ePlane should not stand for electric and covered a lot of areas explaining why electric aircraft or hybrids are not the best way to environmentally friendly air transport.
We now recap what we learned and then wrap the series.
March 13, 2020, ©. Leeham News: In this week’s Corner, we address an often forgotten aspect of Electric and Electric-Hybrid aircraft design.
The battery as an energy source, as the only or assisting source, has the same weight during the whole flight. A fuel (alternate, fossil, or hydrogen) consumes during the flight. You gradually fly a lighter aircraft. Let’s see how this affects the aircraft’s efficiency.
March 6, 2020, ©. Leeham News: We use this week’s Corner to discuss the safety hazards a change to an Electric or Hybrid-Electric airliner introduces.
The trigger is two battery fires in six weeks for the electric aircraft prototypes which are now flooding the market.
February 28, 2020, ©. Leeham News: We now look at technology developments that make sense, and can deliver real improvements in the near future.
We start in this Corner with what more electric aircraft and engines can bring.
January 31, 2020, ©. Leeham News: We now look at ways to increase the fuel efficiency of our airliner and by it, improve the CO2 situation for our environment.
Let’s start with understanding where we are with the efficiency of our present air transport system. To get a feel for where we are we will compare it to our road transport system.
January 17, 2020, ©. Leeham News: We continue our series why e in ePlane shall stand for environment and not electric, where we now examine the gains with electric/hybrid distributed propulsion systems.
We started last week with the type of boundary layer ingesting aft fans shown in Figure 1. Now we continue with wing mounted distributed propulsors.
