Energy security means having reliable, affordable and resilient access to energy. As electricity demand rises across industries and communities, that definition is expanding. It now goes beyond keeping fuel supplies available to include reliable electricity, resilient infrastructure, stable supply chains and systems that can withstand disruptions from extreme weather, cyber threats and geopolitical instability.

That broader view is becoming more urgent as global energy systems grow more interconnected and complex. According to a 2025 report from the International Energy Agency, energy security now extends beyond traditional supply concerns to include electricity reliability, critical minerals, supply chain resilience and system flexibility. Growth in AI data centers, industrial electrification, electric vehicles and hydrogen production is also increasing pressure on energy systems to deliver more power, more reliably.

Why resilience and flexibility matter

Modern energy systems must do more than generate power. They must also adapt to changing demand, integrate diverse energysources and continue operating under difficult conditions. That is why resilience and flexibility are becoming central to energy security.

In practical terms, resilience means energy infrastructure can better withstand disruption and recover quickly. Flexibility means systems can respond to shifting demand and changing generation patterns, especially as more renewable energy comes online.

These needs are creating demand for advanced materials that can help equipment perform in extreme environments, support reliability and reduce maintenance pressure over time.

How 3M helps customers address energy challenges

3M works with customers across the energy landscape to help address challenges related to reliability, durability and performance. Its materials science capabilities support applications across grid infrastructure, energy storage, renewables, geothermal, nuclear, oil and gas operations, and hydrogen. Across these applications, technologies such as 3M™ Cable Accessories and other advanced materials designed for harsh operating environments help support electrical reliability and system performance.

Rather than relying on any single technology, energy security depends on a more diverse and connected system. 3M’s role is to help customers improve the performance of critical components and infrastructure used throughout that system.

“Energy security is no longer defined by a single fuel source or technology. It requires a diverse and resilient energy ecosystem,” said Stefanie Engbrocks, Global Energy Director at 3M. “Through materials science and close collaboration with customers, 3M is helping enable the performance, reliability and efficiency needed to power the future.”

Where 3M is supporting the energy transition

One critical area is energy storage. Battery Energy Storage Systems, or BESS, help store electricity for later use. They can improve grid stability, support renewable energy integration and strengthen resilience during periods of high demand or supply disruption. 3M supports stationary energy storage manufacturers with materials used for thermal management, insulation, bonding and protection, etc.

Hydrogen is another emerging area with potential to support a more diversified energy future. 3M supports hydrogen applications through materials used in production, storage and transportation, including insulation solutions such as 3M™ Glass Bubbles for cryogenic applications where thermal performance and durability are critical.

“As energy systems become more diverse and interconnected, the materials used inside them matter more than ever,” said Ashwini Balasubramanian, Transportation and Energy R&D Vice President at 3M. “The ability to manage heat, protect critical components and support durability can make a meaningful difference in system resilience.”

3M also supports customers working across more established and evolving energy sectors, including grid modernization, geothermal systems, oil and gas, and next-generation nuclear technologies.

Collaboration will shape the future of energy security

Energy security is too complex for any one organization to solve alone. Progress depends on collaboration across industry, government and technology providers. 3M works with customers and partners to help address evolving energy needs with materials and technologies designed to improve system performance and resilience.

As the global energy landscape continues to evolve, 3M is helping customers and communities prepare for a future that requires energy systems to be not only efficient, but also secure, flexible and resilient.
