21.9 GWh of battery energy storage systems (BESS) was installed in Europe in 2024, marking the eleventh consecutive year of record breaking-installations, and bringing Europe’s total battery fleet to 61.1 GWh. However, the annual growth rate slowed down to 15% in 2024, after three consecutive years of doubling newly added capacity.

EU energy storage initiatives are a key part of advancing energy security and the transition toward a carbon-neutral economy, improving energy efficiency, and integrating renewable energy sources into electricity systems, and can play an integral role in balancing power grids and saving surplus energy.
It can also facilitate the electrification of different economic sectors, notably buildings and transport. The main energy storage method in the EU is by far 'pumped hydro' storage, but battery storage projects are rising. A variety of new technologies to store energy are also rapidly developing and becoming increasingly market-competitive.
The European Commission in 2020 published a study on energy storage, which summarized some previous studies and reports, explored current and potential energy storage markets in Europe, and set out policy and regulatory recommendations for energy storage.
As renewable energy continues to expand in Europe, energy storage must keep pace to ensure the grid remains flexible and stable. The Energy Storage Coalition urges the European Commission to develop an Action Plan on Energy Storage, providing much-needed regulatory clarity and supporting Member States in scaling up energy storage capacity.
The global residential solar storage and inverter market is experiencing rapid expansion, with demand increasing by over 300% in the past three years. Home energy storage solutions now account for approximately 35% of all new residential solar installations worldwide. North America leads with 38% market share, driven by homeowner energy independence goals and federal tax credits that reduce total system costs by 26-30%. Europe follows with 32% market share, where standardized home storage designs have cut installation timelines by 55% compared to custom solutions. Asia-Pacific represents the fastest-growing region at 45% CAGR, with manufacturing innovations reducing system prices by 18% annually. Emerging markets are adopting residential storage for backup power and energy cost reduction, with typical payback periods of 4-7 years. Modern home installations now feature integrated systems with 10-30kWh capacity at costs below $700/kWh for complete residential energy solutions.
Technological advancements are dramatically improving home solar storage and inverter performance while reducing costs. Next-generation battery management systems maintain optimal performance with 40% less energy loss, extending battery lifespan to 15+ years. Standardized plug-and-play designs have reduced installation costs from $1,200/kW to $650/kW since 2022. Smart integration features now allow home systems to operate as virtual power plants, increasing homeowner savings by 35% through time-of-use optimization and grid services. Safety innovations including multi-stage protection and thermal management systems have reduced insurance premiums by 25% for solar storage installations. New modular designs enable capacity expansion through simple battery additions at just $600/kWh for incremental storage. These innovations have improved ROI significantly, with residential projects typically achieving payback in 5-8 years depending on local electricity rates and incentive programs. Recent pricing trends show standard home systems (5-10kWh) starting at $8,000 and premium systems (15-20kWh) from $12,000, with financing options available for homeowners.
