The increasing deployments in the oil and gas sector are expected to drive the growth of the high-temperature battery market. Oil and gas are natural resources, primarily crude oil and natural gas, extracted from the Earth and used as fuel and raw materials for energy production and petrochemical products. As global energy demand grows, oil and gas companies are expanding exploration and production efforts to ensure a stable supply, supporting energy security and economic growth. High-temperature batteries are vital in this sector, providing reliable and durable power solutions for equipment and operations in extreme conditions, which helps maintain continuous performance, reduce downtime, and enhance operational efficiency. For example, in December 2024, the Energy Information Administration, a U.S. government agency, reported that in 2023, U.S. oil production averaged 13.3 million barrels per day, and natural gas production reached 128.8 billion cubic feet per day in December 2023. Consequently, the increasing oil and gas deployments are contributing to the growth of the high-temperature battery market.

Leading companies in the high-temperature battery market are focusing on developing advanced products such as AGM technology-based high-temperature batteries to meet the rising demand for reliable energy storage solutions. AGM technology-based high-temperature batteries are sealed lead-acid batteries with Absorbent Glass Mat separators that hold the electrolyte in place for safe, leak-free operation. These batteries are designed for consistent performance and extended lifespan, even in extreme temperatures. For example, in November 2023, Exide Technologies, a U.S.-based energy storage solutions company, introduced the Sprinter Pure Power battery range, designed for data center UPS and other high-demand stationary applications. The batteries feature advanced pure lead AGM technology for greater reliability, durability, and power density, offering over 12 years of design life, 20% more power at high-rate discharge, and reduced total cost of ownership due to better charge efficiency and space savings compared to traditional AGM batteries.

In March 2025, Horien Salt Battery Solutions, a Switzerland-based manufacturer of sodium metal chloride batteries, partnered with Inlyte Energy, Inc. to advance safe, sustainable, and affordable energy storage. The collaboration aims to accelerate large-scale production of next-generation iron-sodium batteries in the U.S., combining HORIEN’s manufacturing expertise with Inlyte’s technology to simplify supply chains, reduce costs, and enable long-duration energy storage by 2027. Inlyte Energy, Inc., based in the U.S., specializes in advanced iron-sodium battery systems.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

Tariffs have influenced the high-temperature battery market by increasing costs for imported raw materials such as sodium compounds, specialty ceramics, and advanced battery components, affecting overall manufacturing economics. These impacts are most visible across energy storage systems and industrial applications, particularly in regions dependent on cross-border supply chains such as Asia-Pacific and parts of Europe. Elevated tariffs have slowed short-term adoption and increased pricing pressure for utilities and manufacturers. However, they have also encouraged localized production, supply chain diversification, and domestic manufacturing investments, supporting long-term market resilience and regional self-sufficiency.
