The main researches must be dedicated to a wider exploration of

the means for reducing the atmospheric impact of other non-CO2, gaseous emissions such as water vapor.

Aircraft running on hydrogen still emit water vapour and, in the case of hydrogen combustion, also NOx. On the other hand, particles may strongly be reduced.

As a consequence, high altitude phenomena have a substantial impact on the global impact
of aviation on global warming through radiative forcing, may strongly be modifed. Decreasing
the level of this impact is crucial in order to increase the environmental potential of H2 aircraft. .

The technology we propose can be used in the design of equipment that solves this problem.

Water is present in the atmosphere. It is pumped by compressors into the pneumatic
systems.

The use of separators, filters and dryers solves these problems

The reason for the significant consumption of electricity by compressors is

due to the laws of thermodynamics.

Reducing the amount of compressed air used to adsorbent regeneration is a challenge that must be addressed to reduce the cost of air production.
