Airbus presents the modular eco-planes of the future powered by hydrogen As a greener alternative is needed for all modes of transport, aircraft manufacturers are also testing modern solutions, one of which may be special hydrogen capsules.

We are talking about a solution located along the sashes, which can be easily mounted or removed if necessary, because in fact we are talking about a modular structure with the option of quick adaptation to current needs. On the presented graphic materials, we can see a prototype of an aircraft called ZEROe, on which 6 such hydrogen tanks were mounted. Interestingly, however, they are not ordinary "canisters", because inside you will find not only a hydrogen container, but also a cooling system, fuel cell, power electronics, electric motors, light 8-blade propellers and all the equipment necessary to the capsules acted as independent motors.

Interestingly, there is no mention of a buffer battery here, but on the other hand, traditional airplanes such as the one shown in the graphics consume power in a constant and predictable way, so the slight delay that occurs at fuel cells should not be a problem here. Airbus announces that it is a highly modular structure that can be quickly disassembled for maintenance, testing or simple component replacement. Why hydrogen? First, liquid hydrogen produces a similar level of energy density, and even better, than long-distance aviation fuel, and boasts zero local emissions and the potential to be filled with carbon-neutral renewable energy.

Why detachable capsules? This is a great solution for airlines for several reasons, first of all, it frees up space in the cabin, which means that you can take more people on board, and also increase the payload, i.e. you can carry more cargo. What's more, if we have 6 such units at our disposal, in case something goes wrong, you can quickly turn one off, and even detach it in a safe place. In addition, the failure will no longer mean the need to ground the aircraft, because it is enough to replace one module and we are ready for further flights. Airbus has already decided to patent its solution, but it also announces that this is just the beginning and literally one of many ideas under the ZEROe program. This capsule configuration is a great starting point to look at how we can scale hydrogen technology for commercial aviation. This is one option, but many more concepts will turn into concepts before we make the final selection, this decision is expected by 2025 - explains the company's representative.
