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. . Lithium-ion batteries are being widely deployed in vehicles, consumer electronics, and more recently, in electricity storage systems. These batteries have, and will. . Goals that aim for zero emissions are more complex and expensive than NetZero goals that use negative emissions technologies to achieve a reduction of 100%. The pursuit of a zero, rather than net-zero, goal for the electricity system could result in high. . The intermittency of wind and solar generation and the goal of decarbonizing other sectors through electrification increase the benefit of adopting pricing and load management options that reward all consumers for shifting electricity uses with some flexibility away. Storage enables electricity systems to remain in balance despite variations in wind and solar availability, allowing for cost-effective deep decarbonization while maintaining reliability.
