The Jupiter 1000 program operates a “power to gas” system on its Fos-sur-Mer site which uses surplus renewable electricity to transform it into hydrogen and synthetic methane.
This is the major problem with renewable electricity sources: their intermittency, directly linked to meteorological hazards, does not allow a continuous supply and makes it necessary to consume or store the electricity produced. The other problem is that storage technologies are not yet sufficiently developed to allow regularity in supply. In other words, storage when production is greater than demand and distribution when demand is greater than production.
The project proposes another means of storage called ” power to gas ” dedicated to responding to the problem of overproduction and storage of renewable electricity. Literally “from power to gas”, the idea of the project, led by the natural gas transport company GRTgaz , is to convert this low-carbon electricity into hydrogen and synthetic methane, which are easier to store and transport.
Sciences et Avenir visited the Jupiter 1000 development platform , located on the Fos-sur-Mer industrial site, near Marseille, to better understand the operation and ambition of such a project.
“The dynamics of the hydrogen sector are booming”
First in the family of the periodic table of elements, hydrogen may be the most abundant atom in the Universe, but it is very difficult to exploit it in its pure state on Earth. However, today, France, like many other countries, wishes to bet on this energy vector to fulfill its energy transition objectives. “The dynamics of the hydrogen sector are booming and several projects, including Jupiter 1000, aim to decarbonize its production, which today is mainly derived from fossil energy” , says Anthony Mazzenga, director of the renewable gas division & hydrogen at GRTgaz.
Even if certain application ambitions still face many technological obstacles, particularly in the mobility sector, it is in the sect.
