Fossil-fuel thermoelectric generators help protect metal pipelines and marine structures from corrosion by providing the necessary power for cathodic protection.

These generators, which typically use fuels such as natural gas, propane, or kerosene, are particularly useful in remote areas where traditional power sources may be unavailable. By generating a steady supply of direct current, these devices prevent electrolysis—a process that causes metallic structures to corrode—thereby extending the lifespan and structural integrity of pipelines and marine infrastructure.12
