Grid-scale storage plays an important role in the Net Zero Emissions by 2050 Scenario, providing important system services that range from short-term balancing and operating reserves, ancillary services for grid stability and deferment of investment in new transmission and distribution lines, to long-term energy storage and restoring grid operations following a blackout. 

Pumped-storage hydropower is the most widely used storage technology and it has significant additional potential in several regions. Batteries are the most scalable type of grid-scale storage and the market has seen strong growth in recent years. Other storage technologies include compressed air and gravity storage, but they play a comparatively small role in current power systems. Additionally, hydrogen – which is detailed separately – is an emerging technology that has potential for the seasonal storage of renewable energy.  

While progress is being made, projected growth in grid-scale storage capacity is not currently on track with the Net Zero Scenario and requires greater efforts. 

Our Next Energy's three-part mission:


We are doubling range so we can make an electric vehicle the only vehicle consumer needs.


We are prioritizing safety by reducing the risk of thermal runaway through chemistry and pack design.


We are more sustainable, Abundant material to build U.S. supply chain.

Time travel for green energy

Aries Grid means you can now use 10:00 AM sunshine power in the middle of the night. Every Aries Grid container holds 45 durable, cost-effective, tried-and-true Aries LFP EV packs — enough energy storage to power 45 class 5 trucks. The bottom line is Aries Grid lets you use far more renewable energy than you could before — whenever you want to use it.
