What is the future of energy storage?
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.
Are batteries the future of energy storage?
Developments in batteries and other energy storage technology have accelerated to a seemingly head-spinning pace recently — even for the scientists, investors, and business leaders at the forefront of the industry. After all, just two decades ago, batteries were widely believed to be destined for use only in small objects like laptops and watches.
Why is energy storage important?
A crucial factor motivating these safety improvements — and the broader focus on developing energy storage solutions more generally — has been the realization that energy storage is a necessary component in scaling up clean energy solutions to power society.
Why do we need a co-optimized energy storage system?
The need to co-optimize storage with other elements of the electricity system, coupled with uncertain climate change impacts on demand and supply, necessitate advances in analytical tools to reliably and efficiently plan, operate, and regulate power systems of the future.
