There is a consensus in the industry that deep decarbonization in the electric power system will not be achieved without a combination of storage technologies, with durations ranging from short-term to emerging, advanced long-term technologies. This decarbonizing the power system will likely require high penetration of variable renewable technologies such as wind in solar. The intermittent nature of these technologies, at high penetration levels, has the potential to create gaps in power delivery. These gaps can be from short-term fluctuations with over/under supply, or long-term issues related to weather patterns. Energy storage can fill these gaps with technologies that can align with each of the power gaps that may arise when efforts to decarbonize the power sector lead to renewable penetration levels in the range of 70-100%. Hence, this tutorial will focus on energy storage technologies and help participants understand storage technologies and how best to apply short-term and long-term technologies to the challenges created by high penetration of renewables. The tutorial will help attendees understand all aspects of short and long-duration storage in a session that covers (1) technologies – short and long duration, (2) challenges created by high penetration of renewables, (3) applications for energy storage and markets that can support those technologies in a deeply decarbonized power system, (4) latest updates on standards for deploying storage, and (5) a review of safety issues with the technologies.
