The Future of Battery Energy Storage

March 04, 2024

Energy storage is key to successfully integrating intermittent renewables into the power grid. Although pumped hydro has been used to store energy for decades, most recently, battery energy storage systems (BESS) using lithium-ion batteries have become popular.

According to a McKinsey and Company analysis, more than $5 billion was invested in BESS in 2022, an almost threefold increase from the previous year. By 2030, the BESS market worldwide is predicted to reach between $120 and $150 billion.

Several factors drive the rapid deployment of BESS. First, the increasing penetration of renewable energy sources has introduced challenges in grid management due to their intermittent nature. BESS can effectively store excess renewable energy when production exceeds demand, ensuring a reliable and consistent electricity supply.

Second, advancements in battery technology have led to significant cost reductions and performance improvements. Lithium-ion batteries, the dominant technology for BESS applications, have seen a substantial price drop, making them more economically viable. Additionally, innovations in battery chemistry and manufacturing processes have enhanced these batteries' energy density and lifespan.

Third, supportive policies such as the IRA and other incentives are critical in promoting BESS adoption. Government programs, such as tax credits and rebates, have helped to offset the upfront costs of BESS installations, making them more attractive to investors and developers. Additionally, regulatory frameworks are evolving to recognize the value and potential of BESS to enhance grid stability and reliability.

The deployment of BESS is expected to continue rapidly in the coming years. The EIA projects that utility-scale BESS capacity will reach 14 GW by 2025 and 30 GW by 2030 in the U.S. The expansion of renewable energy sources will drive this growth, in addition to the need for grid flexibility and resilience and the ongoing cost reductions and performance improvements in battery technologies.

BESS are poised to transform the global energy landscape, providing a range of benefits that will shape the future of electricity generation and distribution. Electrification of nearly everything presents one of the only practical ways to address climate change. When integrating renewable energy sources is enabled, enhancing grid reliability and reducing emissions, BESS create a more sustainable and resilient energy system.
