To summarize all these patents, less energy is expended for the catalytic decomposition of water.
Than what we can get by burning the resulting hydrogen. Do I understand correctly?

In the patents from the previous message, static methods for producing hydrogen are described.

A patent GEP20074038B from Kapanadze's homeland describes a dynamic method, which, according to the patent, has many times greater productivity.

Static hydrogen production method:
English translation, after downloading, is need to add the file extension .pdf :

Amount of Calcium Oxide Powder: 200 grams
The amount of water vapor present in the reactor: 50 grams
Pressure in the reactor: 0,87 atmospheres
(But about the pressure in this patent, it is not entirely clear. If you study other patents of this author, there are indications that in the process of preparing "calcium hydroxide" he lowered the pressure to 0.01 atmospheres)

Amount of hydrogen: 48 cubic centimeters of gas:  0,0043 grams hydrogen
Dynamic hydrogen production method:
   A method comprises heating water vapor together with the catalyst at pressure 8,0-10,0 atm. The received mix is cooled during (3-5)х10-3sec. up to temperature 70,0-80,00С and simultaneously with it pressure is lower up to 0,5-0,7atm. Then by means of addition water vapor hydrogen is isolated and process is repeated.

English translation, .pdf:

Amount of Calcium Oxide Powder: 200 grams
Pressure inside the reactor: 0,5 - 10 atmospheres
Temperature 70 - 400 Celsius
Water  100 ml

Amount of hydrogen: 0.66 - 0.72 % from the water, or  0.66 - 0.72 grams hydrogen, 7788 cubic centimeters of gas, 84 kilojoules if burned.

At idle, a running car engine consumes about 1 liter per hour.

1 liter of gasoline releases 44 megajoules of heat when burned. 84 kilojoules, obtained from the combustion of hydrogen, is enough to rotate the engine at idle for 7 seconds.
Presumably in this way there is enough energy to start and rotate the motor on this videos:
