Bjorn’s Corner: The challenges of hydrogen. Part 22. Hydrogen fuel cells

January 29, 2021, ©. Leeham News: Over the last weeks, we looked at Center of Gravity (CG) problems with rear fuselage liquid hydrogen tanks as used in Airbus’ ZEROe turbofan airliner concept. We can conclude that the CG… Read More

Bjorn’s Corner: The challenges of hydrogen. Part 21. Hydrogen airliner weight shift

January 22, 2021, ©. Leeham News: In last week’s Corner, we looked at how the hydrogen consumed in the rear fuselage tanks changes the airliner’s Center of Gravity (CG). Now we discuss how this change of Center of… Read More

Bjorn’s Corner: The challenges of hydrogen. Part 20. Hydrogen airliner weight shift

January 15, 2021, ©. Leeham News: In last week’s Corner, we looked at how hydrogen consumed in the rear fuselage tanks of Airbus’ ZEROe concept affect the airliner’s efficiency. Now we look at other aspects of the rear… Read More

Bjorn’s Corner: The challenges of hydrogen. Part 19. Hydrogen airliner weight shift

January 8, 2021, ©. Leeham News: In our Corner before Christmas we discussed the hydrogen tank placement at the rear of the aircraft for Airbus’ ZEROe concept turbofan aircraft. We now calculate how the weight transfer when emptying… Read More

Bjorn’s Corner: The challenges of hydrogen. Part 17. Hydrogen airliner program

December 11, 2020, ©. Leeham News: We use this Corner to define the time table for our hydrogen airliner program and for what areas we need to conduct risk-reducing research before we embark on an actual design. As… Read More

Bjorn’s Corner: The challenges of Hydrogen. Part 16. A Hydrogen airliner

December 4, 2020, ©. Leeham News: To dig a level deeper into the challenges of hydrogen airliners, as a next step we design such a plane (on a high level), now that we have covered the basics. It… Read More

Bjorn’s Corner: The challenges of Hydrogen. Part 15. Hydrogen cost

November 13, 2020, ©. Leeham News: In our series on hydrogen as an energy store for airliners, we now look at the cost of hydrogen. The current cost-efficient production is predominantly by reforming natural gas, meaning it’s a… Read More

Bjorn’s Corner: The challenges of Hydrogen. Part 13. The supply of Hydrogen

October 30, 2020, ©. Leeham News: In our series on Hydrogen as an energy store for airliners we now address the problem of liquid hydrogen supply for air transport. Before we go into the ecosystem and its costs,… Read More

Bjorn’s Corner: The challenges of Hydrogen. Part 12. Safety

October 23, 2020, ©. Leeham News: In our series on Hydrogen as an energy store for airliners we look deeper at the safety of a hydrogen airliner. Do the safety rules for the aircraft or the airport need… Read More

Bjorn’s Corner: The challenges of Hydrogen. Part 11. Emissions

October 2, 2020, ©. Leeham News: In our series on Hydrogen as an energy store for airliners we look deeper at the emissions from a hydrogen airliner and compare it to the emissions from today’s carbon fueled aircraft.
