Abstract
The process comprises recovering heat power from a geothermal fluid emitted at a hydrothermal active site at the bottom of a body of water, in particular at a bottom of a lake, a sea or an ocean; converting the recovered heat power into electricity in the body of water or at the surface of the body of water; powering at least an equipment with the electricity obtained from converting the recovered heat power; simultaneously injecting a carbon dioxide containing stream, in particular a stream of carbon dioxide dissolved in water, in a ground formation at a carbon dioxide injection site next to the hydrothermal active site to carry out a carbonation of the carbon dioxide in the ground formation.

A combined energy production and carbon dioxide mineralization process comprising:
- recovering heat power from a geothermal fluid emitted at a hydrothermal active site at the bottom of a body of water;
- converting the recovered heat power into electricity in the body of water or at the surface of the body of water;
- powering at least an equipment with the electricity obtained from converting the recovered heat power;
- and
- simultaneously injecting a carbon dioxide containing stream in a ground formation at a carbon dioxide injection site next to the hydrothermal active site to carry out a carbon dioxide carbonation in the ground formation,
- wherein a carbonation of the carbon dioxide produces a solid attached to the ground formation.
A combined energy production and carbon dioxide mineralization installation, comprising:
- a recovery unit configured to recover heat power from a geothermal fluid emitted at a hydrothermal active site at the bottom of a body of water;
- a conversion unit configured to convert the recovered heat power into electricity in the body of water or at the surface of the body of water;
- at least an equipment powered with the electricity obtained from the conversion unit;
- and
- an injection unit configured to simultaneously inject a carbon dioxide containing stream in a ground formation at a carbon dioxide injection site next to the hydrothermal active site to carry out a carbonation of the carbon dioxide in the ground formation, wherein the carbonation of the carbon dioxide produces a solid attached to the ground formation.
