Energy storage is a potential substitute for, or complement to, almost every aspect of a power system, including generation, transmission, and demand flexibility. Storage should be co-optimized with clean generation, transmission systems, and strategies to reward consumers for making their electricity use more flexible.
Moreover, the researchers conclude that energy storage capacity cost and discharge efficiency are the most critical drivers for the cost-effectiveness of long-duration storage technologies — for example, energy capacity cost becomes the largest cost driver as discharge duration increases.
And because there can be hours and even days with no wind, for example, some energy storage devices must be able to store a large amount of electricity for a long time.
Thermal energy storage is used particularly in buildings and industrial processes. It involves storing excess energy – typically surplus energy from renewable sources, or waste heat – to be used later for heating, cooling or power generation. Liquids – such as water – or solid material - such as sand or rocks - can store thermal energy.

Dramatic cost declines in solar and wind technologies, and now energy storage, open the door to a reconceptualization of the roles of research and deployment of electricity production, transmission, and consumption that enable a clean energy transition 5, 6.
The research landscape of wind energy technology is characterized by extensive efforts to enhance energy capture and stabilize the intermittent power generation.
In tandem, the development of sophisticated control systems and energy storage technologies enables seamless synchronization of intermittent wind resources with demand fluctuations. Despite recent progress towards these goals, several challenges persist, such as turbine scaling, offshore installations, and resource distribution analytics.
Storage enables electricity systems to remain in balance despite variations in wind and solar availability, allowing for cost-effective deep decarbonization while maintaining reliability. The Future of Energy Storage report is an essential analysis of this key component in decarbonizing our energy infrastructure and combating climate change.
Work towards improving wind energy harvesting includes advancements in turbine design for optimized aerodynamics and new materials exploration to boost reliability and cost-effectiveness of turbines.
Long duration energy storage technologies can include mechanical (for example, pumped hydro and compressed air energy storage), electrochemical (for example, sodium–sulfur batteries and vanadium redox flow batteries), chemical (for example, hydrogen and ammonia storage),and thermal (for example, molten salts and salt hydrates) approaches 6.
