Energy Storage Essential for Renewable Energy Integration
As renewable energy sources represent 32% of the global power mix and 47.3% in the EU, energy storage solutions are critical for preventing waste and enhancing grid stability. The significant reduction in lithium-ion battery costs positions energy storage as a viable investment asset, though challenges in regulation and battery supply remain.

In 2024, renewable energy sources accounted for 32% of global electricity and 47.3% within the EU. However, outdated grid infrastructure led to the curtailment of 787.5 GWh of renewable power in Poland during H1 2025.
The decline in lithium-ion battery costs by 93% since 2010 has made battery energy storage systems a fundamental solution for storing surplus generation from solar and wind. These systems enhance grid reliability and profitability while offering revenue opportunities through capacity payments and power arbitrage. Despite rapid growth in Europe, further investment and improved regulations are necessary to establish battery independence from China and effectively harness renewable energy potential.
