To date, hydrogen is renewable energies’ best ally. The most abundant chemical element in the universe, lightweight and boasting an energy density that is 3 times greater than traditional fuels, it enables excess surplus energies to be stored and their irregularity to be offset. If Energy Observer were to store her energy using solely traditional batteries, she would weigh twice as much!

Today, the 63kg of hydrogen stored on board Energy Observer provides 1MWh of electricity, equivalent to the average electricity consumption (including electric heating) of a 4-person household for one month and 10 days.*

In the 63 Kg of hydrogen, the fuel cell provides 1 MWh of electricity, but also 1 MWh of thermal energy that can be used for heating and hot water.

Though maritime and terrestrial mobility is satisfying the ever-increasing demands for power, speed and reliability, today hydrogen is the only energy vector offering a credible alternative to fossil fuels with no impact on the environment.

Via on-board testing of an energy system based on a mix of renewable energies and hydrogen produced aboard, we are paving the way forward for multiple terrestrial and maritime applications, which can be replicated on the scale of a user, a district or a town.
