Abstract

The photovoltaic module (1) comprises a hermetically sealed enclosure (2) defining an internal volume, a plurality of photovoltaic cells (4), which are adjacent to one another and electrically connected to one another, lying in said internal volume. The photovoltaic module further comprises at least one device (22) for making a dielectric fluid flow through the internal volume of the enclosure (2), the dielectric fluid flowing through the internal volume in such a way as to flow along at least part of each photovoltaic cell (4).

Abstract

It is provided a method for powering an offshore injection facility of carbon storage in a subterranean reservoir. The method comprises flowing CO2 through a pipeline to the offshore injection facility; converting energy provided by the CO2 flow into electrical energy; and powering equipment located at the offshore injection facility using the electrical energy. The method forms an improved solution for electrically powering an offshore injection facility for carbon storage in a subterranean reservoir.

Abstract

The disclosure notably relates to a system for retrievably deploying at least one sensor inside a casing (410) of a flowing well. The flowing well comprises a tubing (420) inside the casing. The system comprises a down carrier (300) fixed around the tubing. The down carrier comprises a first extremity forming a circular opening. The system comprises a clamp (100) comprising one or more receptacles for holding the at least one sensor. A first extremity of the clamp is invariable in rotation. The clamp is configured for compressing from a deployed position in which the clamp is attached to the casing to a retracted position in which the clamp is attached to the down carrier by the engagement of the first extremity of the clamp into the down carrier. The system forms an improved solution for retrievably deploying at least one sensor inside a casing of a flowing well.
