FAQS

Should energy storage be developed?

Developing energy storage has become a global consensus. It was announced at COP29 in late 2024 that global storage capacity will increase to 1,500 GW by 2030, more than six times the 2022 level. As a result, InfoLink maintains a cautiously optimistic outlook for the medium- to long-term development of energy storage systems.

Will energy storage grow in 2023?

Global energy storage’s record additions in 2023 will be followed by a 27% compound annual growth rate to 2030, with annual additions reaching 110GW/372GWh, or 2.6 times expected 2023 gigawatt installations. Targets and subsidies are translating into project development and power market reforms that favor energy storage.

Will energy storage growth continue through 2025?

With developers continuing to add new capacity, including 9.2 GW of new lithium-ion battery storage capacity in 2024 through November 2024 and comparable levels of growth expected through the fourth quarter of 2024, energy storage investments and M&A activity are expected to continue this trajectory through 2025.

Will 9% of energy storage capacity be added by 2030?

We added 9% of energy storage capacity (in GW terms) by 2030 globally as a buffer. The buffer addresses uncertainties, such as markets where we lack visibility and where more ambitious policies may develop that we haven’t predicted. We revised our buffer calculation methodology in this market outlook.

How has cost decline impacted energy storage?

This trend may highlight that the cost decline over the past few years has driven energy storage into an era of accelerated diversification in the global market. The European energy storage market added 19.1 GWh of installed capacity in 2024, up 12.4% YoY, with drastic changes in the ESS landscape throughout the year.

How will energy storage systems impact the C&I sector?

So, the C&I sector is likely to use energy storage systems more and more to increase the amount of renewable energy it uses. This will create big opportunities for ESS providers in the future. Asia-Pacific was the largest market in the world in 2021. This was because countries like China, South Korea, and India needed more energy storage systems.
