UTILITIES & POWER DISTRIBUTION

Protecting the Power Grid

Producing and distributing energy in the form of electricity is the cornerstone of our global economy. Our world operates on the assumption of being able to plug in to the energy grid or stand alone energy production systems.

AC Mitigation for Shared Corridors

Shared right-of-way is changing how utilities think about corrosion. With less available land to work with, pipelines and high-voltage power lines increasingly end up in the same corridor, and that proximity causes corrosion that a standard cathodic protection design was never built to anticipate. The fix is AC mitigation: reducing or eliminating the effects of alternating current on metal structures, particularly pipelines and tanks, that are already protected by a CP system.

Alternating current from nearby power lines causes two separate problems, not one. It corrodes the structure in spots a DC-focused design would never flag as a risk, and it disrupts the CP system's own protective potential, so the system starts behaving inconsistently even though nothing about the underlying design changed. Fluctuating AC potential confuses the protective signal the CP system is trying to maintain, which is why AC-affected sites often show corrosion in places that look, on paper, like they should already be fully protected.

Mitigation is its own discipline inside CP, not a variation on standard design. Grounding the affected structure so induced current has somewhere else to go is the starting point. From there, the toolkit includes solid-state decoupling devices, polarization cells, gradient control mats, and surge protection devices, and the right combination depends on the magnitude of the AC interference and the specific requirements of the structure being protected.

For this type of corrosion, both BADGERCORD Zinc Ribbon Anodes and BADGERCABLE Linear Anodes are common solutions, valued for their galvanic and current-distributing properties along the length of a shared corridor rather than at a single point.

Standalone & Personal Energy Production

With the help of American Carbon Company products, stand-alone energy systems are becoming more common and more efficient, and the utility picture is expanding well past gas distribution pipelines and transmission towers.

Solar installations need structural racking that holds up outdoors for decades with minimal maintenance. BADGERADVANCED Titanium is built for that: its corrosion resistance comes from a stable oxide layer rather than a coating, which holds up in coastal or high-humidity installations where standard steel racking corrodes faster than the panels it supports, and where a technician isn't climbing up to do touch-up maintenance every year.

On the battery side, BADGERADVANCED Graphene is one of the more active areas of development for personal and community-scale energy storage. Graphene additives in battery electrodes can improve conductivity and charge cycling behavior, more relevant now that storage is moving from a purely grid-scale problem to something homeowners and small commercial operators are installing on-site.

Battery storage isn't the only way to bank excess generation. Thermal energy storage, charging a solid material electrically and storing the result as heat rather than as an electrochemical charge, is an emerging alternative for community and industrial-scale systems.

BADGERADVANCED Graphite's thermal stability and heat retention make it a candidate material for this approach: charge the graphite block when generation is high, draw the heat back out later. It's earlier-stage than battery storage commercially, but it sidesteps some of the lifespan and material constraints that come with electrochemical batteries.

Hydrogen sits on both ends of the storage picture. Producing it runs on electrolysis, splitting water into hydrogen and oxygen with an electric current, and BADGERCHROME Water Treatment Anodes are built around the same dimensionally stable anode technology used in hypochlorite generation, adapted for that electrolysis step. On the consumption side, hydrogen fuel cells convert the stored hydrogen back into electricity through an electrochemical reaction rather than combustion, a technology still developing rather than settled. The same electrolysis-based systems do double duty in off-grid or community-scale water purification, useful for a standalone installation that needs both power and clean water without a utility connection to either.

Protection at the Point of Delivery

The last mile of energy distribution falls on utility companies, and it is a different problem than transmission-scale corrosion control. Last-mile infrastructure is high-volume and geographically dispersed: meters, gas risers, service lines, and small residential propane tanks scattered across thousands of individual sites rather than concentrated along one pipeline right-of-way.

The scale and the dispersed nature requires a different perspective from large asset CP system design. A utility's last-mile footprint needs a standardized, repeatable solution a field crew can install consistently across a huge number of small, similar sites without custom engineering at every stop.

BADGERCONNECT Magnesium Anodes are built for that. They protect and isolate corrosion on individual parts of a system, meters and gas risers being the most common examples, with a compact, reliable galvanic anode that does not need the design overhead of an impressed current system. Small residential above and below ground propane storage tanks are also heavy users of BADGERCONNECT Magnesium Anodes for the same reason: high volume, dispersed locations, and a solution that works the same way in nearly every installation environment.
