Foreword and acknowledgmentsThe Future of Energy Storage study is the ninth in the MIT Energy Initiative’s Future of series, which aims to shed light on a range of complex and vital issues involving
Long duration energy storage technologies can include mechanical (for example, pumped hydro and compressed air energy storage), electrochemical (for example, sodium–sulfur batteries and vanadium redox flow batteries), chemical (for example, hydrogen and ammonia storage),and thermal (for example, molten salts and salt hydrates) approaches 6.
Moreover, the researchers conclude that energy storage capacity cost and discharge efficiency are the most critical drivers for the cost-effectiveness of long-duration storage technologies — for example, energy capacity cost becomes the largest cost driver as discharge duration increases.
Together, the model enhancements opened the door to exploring many new research questions about energy storage on the future grid. Across all modeled scenarios, NREL found diurnal storage deployment could range from 130 gigawatts to 680 gigawatts in 2050, which is enough to support renewable generation of 80% or higher.
NREL examined 15 energy storage technologies at various stages of commercialization. Ignoring cost, most of these technologies could support the grid with either short or long durations. However, rapid declines in lithium-ion battery costs make it the most attractive energy storage technology.
This research was supported by a grant from the National Science Foundation, and by MITEI’s Low-Carbon Energy Center for Electric Power Systems. Researchers from MIT and Princeton offer a comprehensive cost and performance evaluation of the role of long-duration energy storage technologies in transforming energy systems.

Some dramatically different approaches to EV batteries could see progress in 2023, though they will likely take longer to make a commercial impact. One advance to keep an eye on this year is in so-called solid-state batteries. Lithium-ion batteries and related chemistries use a liquid electrolyte that shuttles charge around;. . Lithium-ion batteries keep getting better and cheaper, but researchers are tweaking the technology further to eke out greater performance and. . The Inflation Reduction Act, which was passed in late 2022, sets aside nearly $370 billion in funding for climate and clean energy, including billions for EV and battery manufacturing.. Bloomberg nef, a research firm, expects makers of sodium batteries, led by China’s HiNa, to begin large-scale manufacturing for grid storage in 2025. Form Energy, an American startup, has raised $1.2bn to develop a low-cost battery based on iron-air chemistry. It will start operations in 2025 in California and Minnesota. [pdf]
