Clean Energy Storage Market Growth

Mid‑2026 forecasts highlight rapid expansion across several clean‑energy storage technologies. A July 13 report projects the enhanced geothermal systems market to double from $6.2 billion in 2025 to $12.9 billion by 2035, while the global redox flow‑battery market is expected to grow almost ten‑fold to $10.4 billion over the same period. Growth drivers include rising renewable‑energy demand, advances in drilling and battery chemistries, and supportive policies in North America, Europe and the Asia‑Pacific.

A July 29 outlook expands the picture to stationary batteries and energy‑management systems. The stationary‑battery market is projected to climb from $24.2 billion in 2025 to $75.2 billion by 2035, driven by grid‑stability needs, large‑scale battery energy storage deployment, and modernization of aging power‑grid infrastructure. Lithium‑ion remains dominant, but emerging chemistries such as sodium‑ion, flow batteries and solid‑state are gaining interest. Concurrently, the EMS market is forecast to rise from $43.7 million to $145.2 million, reflecting increased adoption of AI‑enabled, IoT‑connected platforms that optimise renewable integration and demand‑response.

An August 6 update adds Battery Energy Storage Systems (BESS) and Long‑Duration Energy Storage (LDES) to the growth narrative. The LDES market, valued at $3.27 billion in 2025, is expected to reach $4.93 billion by 2034, with North America holding a 37 % share. Large‑scale projects—including a 25 MW/100 MWh gravity‑storage system in China and multi‑gigawatt pumped‑hydro installations in India—illustrate expanding deployment. Policy support from the U.S. Inflation Reduction Act, the UK revenue‑guarantee scheme, India’s 2025 budget, and DOE funding further fuels market momentum. Together, these trends portray a broad, accelerating market for diverse energy‑storage solutions as utilities and industry pursue decarbonisation, grid resilience and energy‑security objectives.
