Peak Nano & E&P Technologies Partnership

Engineered to Scale, Qualified for Deployment

As fusion scales toward repetitive operation, reliable pulsed power becomes mission-critical. Capacitors sit at the center of that challenge.

Peak Nano and E&P Technologies have built a new model for pulsed power innovation, pairing advanced dielectric materials with precision manufacturing.

E&P’s next-generation high-energy-density capacitors, powered by Peak Nano’s NanoPlex™ HDC dielectric film platform, accelerate development and strengthen the domestic industrial base for high-performance energy systems.

Peak Nano × E&P Technologies Partnership

Developing Capacitors for Pulsed-Power Fusion Energy Systems

Peak & E&P are partnering to develop next-generation high-energy-density capacitors, accelerating performance beyond the limits of conventional polymer film to advance a resilient, U.S.-based supply chain for fusion energy and critical power infrastructure.

Our Partnership

As fusion energy moves toward commercialization, one of the clearest bottlenecks is the capacitor. Next-generation pulsed-power drivers demand capacitors that store more energy, run hotter, last longer, and cycle faster than anything available today.

Peak Nano and E&P Technologies are partnering to solve that bottleneck — pairing advanced NanoPlex™ HDC dielectric films with automated U.S.-based capacitor engineering to deliver fusion-grade, high-energy-density capacitors designed for million-shot duty cycles.

Why E&P Selected Peak NanoPlex

Peak Nano NanoPlex™ HDC dielectric film was selected by E&P technologies as the foundation for a new class of high-energy, high-reliability capacitors designed for Impedance-Matched Marx Generators (IMGs), targeting demanding fusion and aerospace environments. 

NanoPlex™ HDC: The Film Built for Where Conventional Dielectrics Fall Short

NanoPlex HDC is engineered by arranging multiple polymers in precise nanoscale configurations to activate electrical, thermal, and mechanical properties that conventional single-polymer dielectrics cannot reach. The result is a dielectric constant 2x that of traditional films, translating to up to 4x more energy stored in the same volume, with full performance maintained at extreme temperatures, no derating required.

E&P Technologies: Turning Breakthrough Film Into Qualified Hardware

E&P turns that film into qualified hardware: optimizing electrode geometry, winding, and packaging for the target application, then running qualification under real operating conditions. The result reduces physical footprint, enables IoT health monitoring, and extends service intervals.

Nanolayered Dielectric Film for High-Energy Capacitors

NanoPlex HDC is a nanolayered metamaterial film engineered to achieve dielectric, thermal, and mechanical properties that conventional single-polymer films cannot reach. Its architecture enables higher energy density and thermal stability in capacitor applications where BOPP has hit performance limits.

HDC Performance vs. Traditional BOPP:

  • Dielectric constant 3.7 to 4.8 (ASTM D150) vs. ~2.2 for BOPP, enabling up to 4x higher energy density per unit volume

  • Operates up to 125 C without derating, compared to BOPP derating above 85 C

  • Up to 5x longer shot life under repetitive discharge, reducing replacement frequency

  • Breakdown strength up to 840 kV/mm (ASTM D149), supporting higher voltage operation per IMG brick

Strengthening U.S. Supply Chains

This collaboration between Peak and E&P directly supports growing national priorities around domestic manufacturing of critical energy components. With U.S.-manufactured NanoPlex HDC film and domestic capacitor production and qualification reduce dependence on foreign sourcing. The goal is to build a secure supply chain and industrial base capacity for fusion and advanced power systems.

As fusion moves toward scale, this will determine how quickly America can deploy it.

"Building resilient domestic capacity for critical components like capacitors is essential if the United States is going to lead in fusion energy. This partnership is a strong example of how innovative materials companies and specialized manufacturers can close key gaps across the industry to enable fusion to scale."

FAQs

Peak Nano and E&P Technologies have partnered to co-develop next-generation high-energy-density capacitors powered by our NanoPlex HDC dielectric film platform. This enables fusion-grade pulsed power systems while strengthening the domestic capacitor supply chain.

Fusion systems require extremely high-power pulsed energy at rapid repetition rates. Capacitors are core to enabling those systems. Scaling fusion will depend on capacitors that can operate reliably over a million-shot lifecycles.

HDC films are engineered by arranging multiple polymers in precise nanoscale architectures, activating new electrical, thermal, and mechanical behaviors. Traditional BOPP films have reached their limits in temperature, energy storage, and duty-cycle performance, making them inadequate for next-generation pulsed-power applications. NanoPlex™ HDC overcomes those limits with higher energy density, improved thermal stability, and enhanced electrical reliability.

E&P brings deep expertise in pulsed power system design, automated U.S. manufacturing, and qualification for demanding fusion and aerospace applications. Together, we’re fast-tracking dielectric film breakthroughs into deployable capacitor hardware.

This partnership directly advances national priorities around domestic manufacturing of critical energy components, aligning with Executive Orders 14005/14017 and recent appropriations emphasizing secure supply chains for economic and national security. 

Capacitors and capacitor films are included as part of the Advanced Manufacturing Tax Credit (45X), and NanoPlex™ HDC films and E&P's capacitors would qualify under the Fusion Manufacturing Parity Act. These federal initiatives were designed to support exactly what this partnership delivers.

No. Fusion is a primary driver, but high-performance capacitors are also foundational for aerospace, defense, and grid modernization. These are multi-use enabling technologies across advanced power markets.
