Introduction Energy Storage Systems (ESS) are a type of system that stores energy for use later, which has provided energy security and reliability, grid stabilization, and more efficient energy usage. In the United States, they provide bulk energy storage for electricity generated from renewable energy sources, such as wind and solar, they assist in avoiding peak electricity demands, and they improve the resilience of the electrical grid. Some common forms of ESS are lithium-ion batteries, flow batteries, and pumped hydro storage. ESS can support all types of energy sectors, including utilities, commercial and industrial users, and residential users. Utilities may use these systems for on-the-grid bulk storage, while commercial and industrial users may use these systems to defer the maximum use of electricity during peak demand. There is a growing market for this technology as all stakeholders progress towards decarbonization and energy independence, and increases in energy costs.

AI technology has the ability to predict energy consumption patterns; analyze the variability that solar and wind generation experience; and the degradation of batteries, allowing more intelligent and proper decision-making on the dispatch of storage. Fluence Energy, for example, utilizes its AI-driven Fluence IQ product using real-time information from the energy market, where the commercial operation of the battery system can be updated as price variations occur (i.e., discharging and charging the battery system whenever to maximize overall value). A. Technology also enables predictive maintenance by processing and monitoring sensor data from the battery system to identify potential failure of the system, where maintenance can be initiated prior to failure. This minimizes unproductive downtime while extending the overall lifespan of the batteries.

Market Dynamics

What Are the Market Drivers in the U.S. Energy Storage Market?

• Increasing penetration of renewable energy The increasing penetration of renewable energy is the fundamental driver for the U.S. energy storage market. Since solar and wind power are both intermittent resources, they will lead to variability in the generation of electricity. Energy storage is essential when it comes to matching supply to demand, storing excess energy, and always being able to provide power. This obviously leads to the need for storage as a solution to variability. Additionally, most states with large renewables sectors, such as California and New York, have established storage mandates within state legislation to meet their state goals, which directly translates into market growth when it comes to storage.
• Favorable government policies and incentives The use of government support will aid in the quick and further adoption of energy storage systems in the U.S. The 2022 Inflation Reduction Act (IRA) provided the Investment Tax Credit (ITC) to standalone storage systems (up to 30% tax credit). Additionally, through state mandates (California Assembly Bill 2514), there are energy storage targets for utilities and businesses to satisfy. With funding from the U.S. Department of Energy (DOE) for battery research and development (R&D) and grid modernization, innovation becomes even easier to achieve. With government backing, these will lower the price tag for developers and move projects along much quicker, especially in demand centers, meaning the market will continue to grow steadily in each area of the market.

What Are the Restraints in the U.S. Energy Storage Market?

• High initial capital for deployment High upfront capital required for deployment is one of the biggest friction points in the U.S. energy storage market. The cost of batteries has been decreasing, but continuing with large-scale installations involves large minimum investments in technology, infrastructure, and conversion or upgrading utility business protocols. Utility-scale lithium-ion battery storage systems that account for about 95% of the current market segment cost utilities thousands of dollars per kilowatt-hour of installed capacity, as larger installations will account for other planning factors that include permitting, interconnection, and operational costs. It is important to note that batteries pose challenges to small businesses or homeowners seeking a utility-grade storage system to obtain credit for long-term savings despite the relatively low upfront costs. Additionally, the lack of access to strong financial incentives in different states creates even larger barriers to entry into the market space. The ability to pursue deployment may vary by state, which can complicate assessments of the full market development potential.
• Limited battery lifespan and recycling challenges A significant limitation for the U.S. energy storage industry is the disposal and recycling of batteries, particularly the limited lifespan of energy storage batteries. With lithium-ion batteries only having a certain lifespan, typically 8-10 years, it’s important to understand the future economics of any long-term sustainability projects. Batteries degrade and become less efficient, and power generation is affected, resulting in maintenance and possibly replacement. While there are procedures in place to recycle batteries when they are no longer usable, the infrastructure for used batteries has not developed in the U.S. To compound this, recycling used batteries while being developed is poorly executed in regard to the environment. The improvement of recycling technologies is moving forward, but safety limitations provide few existing growth opportunities in regard to advancement, and generate uncertainty about investors' purchases. These factors also slow the adoption of energy storage assets (batteries outlined here); however, while lithium-ion as a market grows, it is equally challenged when we consider utility and commercial users who need long-term cap-ex or operating cost-effective solutions.

What Are the Opportunities in the U.S. Energy Storage Market?

Emerging opportunities in the U.S. energy storage market include going "second life" with batteries and vehicle-to-grid (V2G) integration. Reproposing an electric vehicle battery for grid storage keeps the battery in use for a new application and mitigates waste. V2G technology impacts the grid by allowing electric vehicle owners to take their energy back from the vehicle into the grid, creating a dynamic network of storage. Markets for storage technologies are also being created by microgrids, rural electrification, and energy resilience are focused on more distributed energy solutions and diversification. These opportunities can help produce a wide spectrum of economic and environmental benefits in the near future.

Segmental Insights

Why did battery management systems dominate the U.S. energy storage market?

The U.S. energy storage market by source was led by battery management systems (BMS), which are important because they ensure the safe, effective, and long-term operation of a battery. A BMS maintains multiple parameters (i.e., temperature, voltage, and current) in order to ensure that batteries work safely and efficiently, and to avoid failure. This is valuable motivation to ensure a BMS in both utility-scale storage and residential systems. Lithium-ion batteries represent the bulk of storage (and BMS) as they lead the energy storage market, and continued demand for more advanced BMS is expected as more companies launch products to meet demand. With increasing investment in EV infrastructure and large storage installations, the need for reliable BMS (and, as importantly, reliable integration) is going to become widely recognized, and the ultimate value of BMS lies in their function of optimizing performance while extending the service life of batteries.

Why are energy storage systems the fastest-growing segment in the U.S. energy storage market?

Energy storage systems (ESS) are the fastest-growing source segment in the U.S. energy storage market by source. Given their important role in ensuring that power grids are balanced and can support the increasing build-out of renewable energy, ESS is important. With more solar and

wind capacity, we need more systems that can store and deploy electricity on demand. ESS is growing rapidly, both as a stand-alone system and an integrated system in the market across residential, commercial, and utility mini-grids. The emergence of smart grids and decentralized electric power generation is also creating demand. The increase in energy storage systems is also directly attributed to government incentives, such as tax credits, found in energy policies like the IRA, which is helping spur the increase in ESS, and therefore, energy storage systems are the fastest-growing source segment in the current energy landscape.
