Hydrogen has been used safely for many decades in a wide range of industrial applications, including in the food, metal, glass and chemical industries. The global hydrogen industry is well established and produces more than 50 million tonnes of hydrogen per year.

With respect to energy, hydrogen can be used as a fuel for transport, and to generate electricity in fuel cells.

One kilogram of hydrogen can release more energy than any other fuel (almost the triple of gasoline or natural gas), and to release that energy it does not emit any carbon dioxide, only water vapour, so the environmental impact is zero.

A hydrogen internal combustion engine (ICE) vehicle uses a conventional internal combustion engine modified to burn gaseous hydrogen. Hydrogen ICE vehicles are typically about 30% more efficient than comparable fuel vehicles, and perform well under all weather conditions, including cold temperatures.

Hydrogen Stations

A hydrogen refueling station (HRS) is a storage or filling station for hydrogen.

Hidrogenera

It is a relatively new concept and it is intended in transportation is to use fuel cells to replace diesel or gasoline to hydrogen in HRS. It is expected that the stations will be gradually replaced from fossil fuels with petroleum-based to fuel cells or hydrogen.

Hydrogen fuel is intended to be an intermediary between renewable energy and the final user, avoiding the problem of discontinuity generation and mobility in the case of transportation.

Hydrogen stations can obtain hydrogen by electrolysis of water with surplus renewable electricity from wind farms or solar panels located in public parkings.
