For the past two years a large Canadian pipeline company has installed magnesium anodes powered by solar panels to obtain levels of protection in high resistivity environments. Pipelines are remote from
AC power sources, making conventional impressed systems cost prohibitive. Magnesium anodes alone are also cost prohibitive due to the quantities required in high resistivity environments. Solar powered
magnesium anodes have shown to be both a technically and economically sound alternative to conventional methods of supplying cathodic protection current to the company's pipelines in high soil
resistivity environments.
