Up-goer summary: “I study the best way to back up power that comes from the sun and wind. What do we need to build to make our back up power cleaner and safer?” Noah Kittner is a third year PhD student in the Energy and Resources Group. He works on analyzing the sustainability of different energy storage systems to back up intermittent renewables like solar and wind on the grid. The scale up of energy storage systems will require the use of critical metals, materials, and energy to manufacture storage systems. Various types of energy storage technologies are used for different purposes on the grid– and modeling the effects different technology deployment on grid emissions from a holistic view will provide policymakers and grid operators a better framework for planning a new electricity grid.
