Underwater power generation
First Claim
1. A method for providing auxiliary electrical power to an underwater well installation, the installation being linked to a surface location via an umbilical cable, to supplement any electrical power received at the installation from the umbilical cable, the method comprising:
- providing a chemical flow battery at the installation;
providing a chemical supply channel for supplying the flow battery with operating chemicals for the purpose of electrical power generation, the chemical supply channel comprising a flowline housed within the umbilical cable;
supplying the operating chemicals to the flow battery via the chemical supply channel; and
providing an electrical power output line for transferring electrical power generated by the flow battery to the installation, wherein the electrical power generation is caused by a chemical reaction of the operating chemicals.
