North America Flow Battery Energy Storage Container

Containerized Battery Energy Storage Systems (BESS) are essentially large batteries housed within storage containers. These systems are designed to store energy from renewable sources or the grid and release it when required. This setup offers a modular and scalable solution to energy storage.

These energy storage containers often lower capital costs and operational expenses, making them a viable economic alternative to traditional energy solutions. The modular nature of containerized systems often results in lower installation and maintenance costs compared to traditional setups.

The amount of renewable energy capacity added to energy systems around the world grew by 50% in 2023, reaching almost 510 gigawatts. In this rapidly evolving landscape, Battery Energy Storage Systems (BESS) have emerged as a pivotal technology, offering a reliable solution for storing energy and ensuring its availability when needed.

Rating systems were developed for each market application (e.g., energy shifting) and the technology was compared to Li-ions in the same application. All redox flow battery chemistries were grouped together and were assumed to have an average system duration of 4 hours.

The existing capacity in stationary energy storage is dominated by pumped-storage hydropower (PSH), but because of decreasing prices, new projects are generally lithium-ion (Li-ion) batteries.

This report covers the following energy storage technologies: lithium-ion batteries, lead–acid batteries, pumped-storage hydropower, compressed-air energy storage, redox flow batteries, hydrogen, building thermal energy storage, and select long-duration energy storage technologies.
