Because I am convinced that with photovoltaic solar, it is the most suitable way to store solar energy.

The first reservoir based on nanostructured magnesium hydride has just been developed. The hydriding of magnesium is very strongly exothermic, which poses difficulties linked to the management of thermal fluxes. Indeed, the introduction of hydrogen causes a sudden rise in temperature. The equilibrium conditions are immediately reached, stopping the hydrogen absorption reaction. The realization of an adapted heat exchanger made it possible to divide by 4 the loading time. This first tank can absorb 170 liters of hydrogen, with a volume density comparable to liquid hydrogen.
- My vision: a well oriented photovoltaic roof of around 100 m²
- Production: around 20 KW.h annual electricity with current panels (000 times more with future ones)
- Conversion: with an electrolyser performing around 6500M3 of H2 per year
The hydrogen thus stored can therefore supply a fuel cell for electricity, at home or on board, or be used for other direct heating purposes. happiness and energy independence
