Long Duration Energy Storage (LDES)

Long Duration Energy Storage (LDES)

October 23-24, 2023 | Online :: Central Time

“Great class. Full of information to help bring to light the technology of a clean/green energy future.” –   Senior Engineer, Quanta Utility Engineering Services (QUES)

“Great overview of emerging and current technologies in the LDES space with diverse perspectives from utilities, manufacturers and other renewable/resilient energy focused organizations.” – Mechanical Engineer, The RMH Group

Interest in long duration energy storage is escalating rapidly as the growth of variable output renewable generation proliferates and issues with grid stability become more tangible for grid operators.  Energy storage firms, extends and shifts the range of these renewable power resources so they can begin to approximate baseload energy. Long duration storage also promises to improve system reliability during the diurnal and seasonal conditions that otherwise complicate the transition from thermal/fossil generation to a 100 percent renewable energy grid.

This course explores the growing need for long duration energy storage and how it fits with the grid operating requirements of utilities, ISOs and RTOs.  The program will examine how policymakers, regulators and power organizations are influencing the advance of long duration energy storage. Specific types and technologies of long duration storage will be discussed and evaluated, including relative costs and capabilities of different technologies. Finally, the symposium will consider the trajectory of how and when these energy storage solutions can provide the essential bridging functions to 24-hour/7-day/365-day (8760) renewable energy grid operations.

Learning Outcomes

  • Review the history and background of energy storage
  • Discuss what long duration is today and what will it be when renewables provide 50% of the total energy
  • Discuss the growing need for long duration energy storage to accommodate the growing increase of renewable generation on the grid
  • Illustrate the applications for energy storage across the energy industry
  • Review the policy and regulatory environment for long duration storage
  • Identify the various long duration storage technologies, including pumped storage, flow and non-lithium batteries, gravity and hydrogen
  • Review several long duration storage pilot projects and case studies
  • Assess the relative costs and capabilities of different technologies
  • Examine the future outlook and projected outcomes for long duration storage in the next decade or more
