The hydrogen sector is primarily intended to sell fossil fuels ...
The production of hydrogen by electrolysis of water, which would theoretically be the cleanest way to make hydrogen, if this electricity comes from renewable sources,
requires 50 to 85 kWh of electricity to produce 1kg of hydrogen
1kg of hydrogen contains 33kWh of potential energy.
But the use of this energy in a fuel cell gives back less than 90% and sometimes barely 75%
Vehicles are considered to consume 1kg of hydrogen to cover 100km, i.e. 33kwh
However, a hydrogen vehicle is nothing other than an electric vehicle whose source of electricity is a fuel cell ...
The TESLA Model S, equivalent in size to the Toyota Mirai is 4 times more powerful but only consumes 20kWh per 100km
This represents a huge difference in performance ...
Must we use 85kWh of electricity (preferably from renewable origin) to run a Mirai over 100km, or use this same amount of energy to fill the entire Tesla battery and drive 400km ...
Especially since the TESLA has been marketed for more than 2 years worldwide and recharges on any socket outlet at public or industrial tariff or on the network of Superchargers deployed at its expense by the manufacturer which offers free of charge recharging to its customers, recharging takes place between 20 minutes and less than an hour ...
Preparations for the hydrogen economy have been underway for many years. It started with "relaxation" of safety standards which originally considered that transporting 500g of hydrogen required precautionary measures contrary to its use in a fast vehicle ...
All technical, economic, ecological data are final.
The hydrogen economy is not viable.
... unless you subsidize it
There is a race between energy storage on battery and energy storage in the form of hydrogen. But the battery is already operational and economically viable ...
All that remains is the question of the recharging time that many research laboratories think they have solved thanks to nanotechnologies, to promise us batteries, hybrid between the battery and the capacitor, rechargeable in a few seconds.
These batteries will be in point before the development of the hydrogen sector.
