Battery Application Solutions for Oil and Gas Operations

Upstream oil and gas sites sit far from the grid, often in explosive atmospheres and brutal temperatures. Reliable battery application solutions keep instrumentation, SCADA, and emergency systems alive when the generator is down or the sun is low. The design challenge is not just energy, but certified safety in hazardous zones.

Hazardous-Area Constraints

Class I Division 1 and Zone 1 locations ban any spark or hot surface that could ignite gas. Batteries and BMS must live in explosion-proof or intrinsically safe enclosures, with thermal management that cannot exceed the rated surface temperature. Certification (ATEX, IECEx) is non-negotiable for deployment.

What the Sites Power

Common loads are low but mission-critical: pressure transmitters, RTU controllers, valve actuators, and telemetry radios. A modest bank with a good BMS and solar input can run an unmanned site for weeks, cutting helicopter and truck visits that are both costly and risky.

Deployment Tips

Pair the battery with a rated solar charge controller and a low-temperature cutoff for cold sites. Design for the longest expected gap between service visits, and monitor state-of-health remotely so a failing cell triggers a dispatch before the site goes dark. Work with a supplier that holds the required hazardous-area certifications.

People Also Ask

Can lithium be used in explosive atmospheres? Yes, when the cells and BMS are housed in certified explosion-proof or intrinsically safe enclosures rated for the zone.

How long between service visits? A properly sized solar-backed bank can run an unmanned instrument site for weeks to months, depending on load and sun.
