Keynote 2: Defining the Roles of Long-Duration Energy Storage in Grid Decarbonization
Wednesday, January 15th
17:00 – 17:45 | HG F 30 | Audi Max
Abstract:
The most significant focus of climate change mitigations in the recent past has been the remarkable scale-up of renewable electricity generation. However, adding renewables will only get us part of the way to net zero. Long-Duration energy storage is essential for time-shifting variable renewable energy sources to enable deep decarbonization, but how much is needed and at what scale?
This talk will provide an overview of the existing mix and future needs for energy storage in grid applications, addressing factors such as manufacturability, scalability, and acceptable cost at long durations. The technology landscape will also be introduced, focusing on thermal, mechanical, and chemical energy storage concepts.
An analysis framework is presented for net-zero pathway evaluations, with examples that illustrate the scale and duration requirements for cost-optimal energy storage systems as a function of decarbonization level and renewable resource mix. The analysis also provides a comparison of lithium-ion batteries vs. emerging turbomachinery-based energy storage technologies, suggesting areas meriting future technology development and improvement.
