Energy storage technology is designed to be durable and reliable enough to hold on to electrical energy until it needs to be used. With the shift toward renewable energy sources like solar power, batteries and other energy storage systems can help to ensure there’s power available to meet demand. These solutions can come with a variety of other benefits, such as saving utility providers — and by extension their customers — money, as well as providing backup power in the event of an emergency. We’ve rounded up some top energy storage companies coming up with short- and long-term methods of capturing energy for later use.
Energy Storage Companies to Know
Fluence’s energy storage systems are designed for common use cases, yet are customizable for less typical applications. Products include Gridstack, a grid-scale energy storage system, and Sunstack, which stores energy generated by solar energy systems. The company offers four tiers of operational service packages to go with its products: guided service, shared service, complete service and asset management.
Form Energy is an energy tech and manufacturing company that is developing a multi-day battery — a necessary component of a clean energy grid. Using iron-air technology, Form Energy batteries have the capacity to store electrical energy for up to 100 hours. Because they are made of just iron, water and air, the company says the production of these batteries is inexpensive, safety-compliant and sustainable.
Energy Vault specializes in energy storage for short duration and long duration power needs. It provides everything a client has to have to collect and store energy and integrate it into their existing system. Energy Vault’s long-duration solution uses its proprietary “Gravity Energy Storage System” to “autonomously coordinate balanced storage and dispatch of electricity for grid-scale applications.”
Sonnen makes smart home batteries that collect and store solar energy, which can then be used to power homes on a routine or emergency basis. Its three product lines are Evo for outdoor installation, Core+ for indoor installation and ecoLinx, which integrates with smart home automations. Clients can manage usage on the Sonnen app.
Powin sells products for energy storage, including a modular battery system, battery management software and a power conversion system. The company is involved at every level of production, starting with material sourcing, to ensure efficiency and compliance with its sustainability standards. It has engineered and installed photovoltaic, primary frequency response and hybrid grid facilities around the world.
