Exercice 2 an la fait mais
La Guyane doit accueillir une centrale photovoltaique d'une
puissance électrique de 55 MW. Afin de pallier l'intermittence
d'un tel dispositif, un centre de production et de stockage
de dihydrogène lui est associé.
Le dihydrogène est produit grâce à un électrolyseur. Une
pile à hydrogène peut ensuite convertir l'énergie chimique
sous forme électrique.
