The concept of ‘hydrogen economy’ dates back to the 1970s. It was first introduced as
s response to the first oil crisis. In the context of the hydrogen economy, it is important to calculate
how much hydrogen would be needed to power all motor vehicles in the Czech Republic. This is
main topics of this paper. To calculate the amount of hydrogen, we used two different methods.
One is based on thermodynamic laws and the other on normal operating conditions. Both
approaches yielded comparable results. It was found out that even with the use of all the electricity
produced in the Czech Republic in 2016, we would not be able to cover the amount of energy
that is required for production. It would cover only 75% resp. 76% depending on the calculation
method used. Eventually, the Czech Republic could buy necessary amount of hydrogen and it
would cost between 11 and 29 billion euros which is between 6% and 16% of GDP of the Czech
Republic. In the calculations, authors found out that most fuel is burnt in the passenger cars.
Therefore, we made a sensitivity analysis to find out how much our results would differ if fuel
consumption changed. It turns out that with an increase in consumption of 1l per 100 km,
hydrogen production coverage will decrease by about 4% (again with the use of all electricity
produced in the Czech Republic).
