The passage of the IRA in August 2022 gave a major boost to U.S. energy security and climate change efforts. The IRA is expected to propel the U.S. energy storage industry into a new phase of development through generous grants of at least $369 billion, setting the stage for rapid growth over the next decade.

In 2022, the new installed capacity in the United States exceeded 4GW, an increase of 39% from the previous year.Although the growth rate is slightly lower than in previous years, but the United States still is one of the most important participants in the global energy storage market.

A notable trend in the U.S. energy storage industry is the steady growth in the size of single-cell energy storage projects. Compared to the same period in 2021, the average generation capacity of individual battery storage projects increased by more than 60%, and this growth demonstrates the growing importance of energy storage as a means of storing excess renewable energy for later use, especially during periods of low solar or wind production.

To support this continued expansion, the U.S. Department of Energy recently announced a massive $325 million investment. The money will be used to develop new types of batteries that can efficiently combine solar and wind energy to provide stable power over a 24-hour period.

The investment will be distributed to 15 projects in 17 states and one indigenous tribe.The DOE undersecretary for infrastructure emphasized that the funded projects will help demonstrate the practicality and scalability of such technologies, allowing utilities to plan for long-term energy storage and reduce costs in the process.

By investing in these innovative projects, DOE aims to improve energy reliability and affordability while protecting communities from potential power outages. This further highlights the increasingly important role that energy storage plays in ensuring uninterrupted power supply, even when renewables may not be able to be used at full capacity. The U.S. energy storage industry is poised for strong growth and will continue to contribute to the nation's energy security and climate change goals in the coming years.
