Everyone understands that storage will play an important role in the energy transition, as we move from conventional thermal power plants that can be dispatched at will to energy systems predominantly supplied by variable renewables. But important questions remain: how much storage will be needed? What type of storage is best? When will storage be most important? There hasn’t been a lot of great scholarship on these practical implications for deploying storage across the grid so far, but a multi-year project called the Storage Futures Study that was just completed by researchers at the National Renewable Energy Laboratory (NREL) advances the literature considerably. The seven component reports of the Storage Futures Study explore when and where a range of storage technologies are cost-competitive, depending on how they're operated and what services they provide for the grid, as well as the role and impact of relevant and emerging energy storage technologies in the US power sector across a range of potential future cost and performance scenarios through the year 2050. In this episode, we’re joined by Nate Blair, principal investigator of the study, to explain its findings and how their modeling was done. Nate is the Group Manager of the Distributed Systems and Storage Analysis group at NREL, and draws upon almost 30 years of experience in energy systems modeling and energy analysis, including nearly two decades of work at NREL where he held roles developing the System Advisor Model and PVWatts system modeling tools, as well as the ReEDS electric grid planning model. He has deep expertise in this type of modeling and walks us through all of the findings of this important new study.
