The renewable energy storage market size is expected to see exponential growth in the next few years. It will grow to $612.27 billion in 2030 at a compound annual growth rate (CAGR) of 29.4%. The growth in the forecast period can be attributed to rising investments in long duration energy storage solutions, growing integration of storage into renewable power plants, expansion of hydrogen and thermal storage applications, increasing demand for residential and commercial storage systems, rising regulatory support for grid scale storage deployment. Major trends in the forecast period include growing deployment of large scale battery energy storage systems, increasing demand for grid flexibility and renewable stabilization, expansion of hybrid renewable plus storage projects, rising adoption of long duration storage technologies, advancements in thermal and hydrogen based energy storage.

The growing investment in the energy sector is expected to drive the growth of the renewable energy storage market going forward. Investment in the energy sector refers to the allocation of financial resources - such as capital, funds, or assets - toward activities, projects, or infrastructure related to energy production, distribution, and use. This increase in investment is driven by climate change concerns, advancements in renewable technologies, improved efficiency, and declining costs. Investments support renewable energy storage across the entire value chain, including research and development, manufacturing expansion, grid integration, and the deployment of commercial projects. For example, in July 2025, the Department for Energy Security and Net Zero (DESNZ), a UK-based government department responsible for energy security and the transition to net-zero emissions, reported that investment in the energy industry reached approximately $29.8 billion (£23.6 billion) in 2024, representing a 28% increase compared to 2023. Therefore, rising investment in the energy sector is driving the growth of the renewable energy storage market.

Leading companies in the renewable energy storage market are focusing on developing innovative solutions like containerized energy storage systems to increase efficiency. These containerized solutions utilize standardized shipping containers to house battery systems, allowing for easy transport and quick deployment. This modular setup enhances grid stability, facilitates renewable energy integration, and optimizes energy management. For example, in September 2024, U.S.-based GE Vernova Inc. introduced the RESTORE DC Block, a modular Battery Enabled Energy Storage (BESS) solution with a capacity of 5 MWh and an operational duration of 2 to 8 hours. Designed to strengthen grid resilience and improve renewable energy integration, RESTORE DC Block includes advanced safety features, liquid-cooled LFP cells, and flexible installation options, aimed at reducing energy costs and supporting utility-scale renewable energy projects.

In January 2024, TotalEnergies, a France-based provider of integrated energy solutions spanning oil, gas, renewables, and electricity, acquired Kyon Energy for an undisclosed amount. Through this acquisition, TotalEnergies aims to expand its renewable energy storage portfolio in Europe, strengthen its technological capabilities in battery energy storage systems, and accelerate the integration of storage into its renewable projects. Kyon Energy is a Germany-based developer of battery energy storage systems, offering design, construction, and operational management of utility-scale and commercial energy storage projects.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

Tariffs on battery cells, power electronics, and energy storage components have increased system costs for renewable energy storage projects, slowing adoption in markets heavily dependent on imported technologies such as Europe and North America. Industrial and utility scale storage projects face the greatest impact due to high component volumes and capital requirements. However, tariffs are also incentivizing domestic manufacturing of batteries and storage hardware, strengthening regional supply chains and fostering long term competitiveness in the renewable storage ecosystem.
