The energy storage sector maintained its upward trajectory in 2024, with estimates indicating that global energy storage installations rose by more than 75%, measured by megawatt-hours (MWh), year-over-year in 2024 and are expected to go beyond the terawatt-hour mark before 2030.
Driven by the global energy transformation and carbon neutrality goals, the energy storage industry is experiencing explosive growth, but it is also facing multiple challenges such as cost, technology, safety and business model.
At present, energy storage is still an emerging industry, and it cannot be completely said that it has developed very well and maturely, and there is a problem of technological progress in the industry, so trial and error are needed.
"Global energy storage deployment in 2023 achieved record-breaking growth of 162% compared to 2022, installing 45 GW/100 GWh," said Anna Darmani, principal analyst, energy storage, at WoodMac.
Furthermore, the paper assesses the role of energy storage solutions, such as batteries and pumped hydro, in facilitating the integration of intermittent renewable energy sources into the power grid.
New Energy Storage Capacity Surpasses Pumped Hydro Storage! With the support of favorable policies, new energy storage is experiencing explosive growth, although reliance on lithium resources poses the greatest challenge.
The skyrocketing demand for energy storage solutions,driven by the need to integrate intermittent renewable energy sourcessuch as wind and solar into the power grid effectively,has led to a flurry of investments in energy storage projects across the country,the NEA said.

The rapid rise in renewable energy is promising for the planet but challenges energy security, making the emerging energy storage sector crucial for balancing variable energy production.
The energy storage sector maintained its upward trajectory in 2024, with estimates indicating that global energy storage installations rose by more than 75%, measured by megawatt-hours (MWh), year-over-year in 2024 and are expected to go beyond the terawatt-hour mark before 2030.
Energy storage systems (ESS) are being installed in the United States and all over the world at an accelerating rate, and the majority of these installations use lithium-ion-based battery technology.
Continued expansion of intermittent renewable energy, ESG-focused investments, the growing versatility of storage technologies to provide grid and customer services, and declining costs for key components like lithium-ion batteries all played a significant role in driving the investment and development of energy storage.
The energy storage industry has continued to progress over the course of 2024 and into 2025, buoyed in significant part by the federal income tax benefits in the form of tax credits enacted under the IRA. Energy storage was one of the major beneficiaries of the IRA’s new rules on both the deployment and manufacturing sides.
Several competing design objectives for ESS can detrimentally affect fire and explosion safety, including the hot aisle/cold aisle layout for cooling efficiency, protection against water and dust ingress into the enclosure, and the use of larger cells with increased energy density.
For grid-scale and residential applications of ESS, explosion hazards are a significant concern due to the propensity of lithium-ion batteries to undergo thermal runaway, which causes a release of flammable gases composed of hydrogen, hydrocarbons (e.g. methane, ethylene, etc.), carbon monoxide, and carbon dioxide.
