Energy storage: the technology that will cash the checks written by the renewable energy industry. Energy storage can transform intermittent clean energy—primarily derived from wind and solar—into a reliable source of 24/7 generation. As a result, energy storage has seen tremendous policy support from the public sector, including through federal investment tax credits in the United States, as well as a large influx of capital from private investors seeking environmental, social, and governance (ESG) focused investments. The global energy storage market will continue its rapid growth, with an estimated 387 gigawatts (GW) of new energy storage capacity expected to be added by 2030— a 15-fold increase in global energy storage capacity compared to the end of 2021.
