Sandia National Laboratories published its demonstration project with Capacitech. It shows that supercapacitor energy storage systems can enhance power quality and resilience, reducing operational risk across modern power infrastructure—especially for utilities, data centers, and other mission-critical facilities.

Supercapacitor-based power conditioning and buffering — applied at the right layer of the power stack — prevents stress on transformers, feeders, and batteries that reduce operating life.

We are excited to announce that Capacitech Energy was accepted into the NVIDIA Inception program. This program is designed to help push AI-enabling technologies developed by startups to the next level.

For operators responsible for uptime, voltage sags are becoming one of the most important—and least visible—constraints in AI data center expansion. This article explains why they occur, why traditional mitigation methods struggle to respond, and how supercapacitor-based systems like the C-Link™ product suite provide a modular, millisecond-response layer that complements existing infrastructure.

We build high-power and space-conscious energy storage systems for an increasingly complex grid. Our products enhance renewable energy sources, long duration energy storage assets, and overall power quality while overcoming typical integration and physical footprint challenges. With innovations in form factor, power electronic, and energy management technologies, Capacitech is a trusted partner for dynamic and space constrained power applications of varied shape, size and scale.

The emergence of renewables and energy storage resources is changing the grid as we know it. As they make up a larger percentage of the grid, both long duration energy storage and rapid response energy storage technologies are required. Supercapacitors are a well known kind of rapid response energy storage technology that is uniquely capable of addressing disturbances and fluctuations that long duration technologies cannot handle. This article talks about the important role supercapacitors have in stabilizing grids and how Capacitech’s PowerLink addresses one of the critical challenges to using supercapacitors - space constraints.

Batteries stand as the conventional choice for energy storage, yet an exclusive reliance on them poses challenges, especially in terms of safety. The emergence of supercapacitors presents an alternative with distinct advantages, notably stable performance in low temperatures and a remarkable high-power density. In our ever-evolving energy landscape, where batteries integrate into homes, cars, and the electrical grid, safety considerations become paramount. Supercapacitors emerge as a key player in achieving sustainability goals and adhering to safety standards, particularly in densely populated urban areas.

From powering electronic devices, to electric vehicles and renewable energy systems, the use of batteries as an energy storage solution has been prevalent. However, batteries have limitations like slow charging, limited lifespan, and restricted power output. This is where supercapacitors, also known as ultracapacitors or electric double-layer capacitors (EDLCs), step in.

When it comes to powering dynamic, high-power applications, batteries are inefficient and expensive. Luckily, there is a solution - supercapacitors. Supercapacitors are well-known for their ability to help batteries do more by storing large amounts of power by leveraging their extremely low internal resistance, making them ideal for demanding applications that require fast charging and discharging. In this blog post, we will discuss the shortcomings of batteries, supercapacitor technologies, advantages of pairing them with batteries to create the best of both worlds and explore popular supercapacitor solutions.

Energy storage key to the world’s transition to renewable energy sources. Hundreds of gigawatt hours (more than one billion iPhone batteries) are needed to reach our goals, but where will all of that storage physically go? Energy storage systems used in solar farms require tens to hundreds of acres of valuable land. We’re here to change that.

Gas generators may be sufficient for the present, but they are not for the future. Event planners should be making the move towards clean energy sources like solar to power their outdoor events. In this blog we’ll look at an alternative to gas generators, why it can be difficult to adopt, and how Capacitech makes it easier and more affordable to make this adoption.

Here’s the truth: batteries alone can’t power our future. And while other energy storage technologies are available, it’s hard to find viable battery replacements. Perhaps the answer is an addition to batteries instead of trying to replace them. This article discusses the characteristics of batteries and supercapacitors, the benefits of hybrid energy storage systems, the tradeoffs associated with them, and how Capacitech makes it easier to adopt these systems.
