Figure 1.6. Hydrogen technology sector

The building sector also benefits from hydrogen, as there are hydrogen
fuel cells suitable for commercial, residential, or even tertiary uses.

In industry, hydrogen can serve as the energy vector of several
applications such as cogeneration by hydrogen fuel cells, turbines, or even
internal combustion engines; its application in synthetic processes is also
possible.

Hydrogen can therefore provide energy for all sectors of the economy:
industry, homes, transport and portable devices. It can replace petroleum-
based fuels for vehicles and it is an interesting source of electricity for
communities. One of the main advantages of hydrogen, compared to fossil
fuels, is its impact on the environment. Its consumption (by combustion or
by electrochemical conversion) produces no pollutant and no carbon
emissions.
