Energy Storage and Renewable Power:
Is Storage a Solution to Renewable Intermittence and Grid Inefficiency?

The intermittent nature of natural, carbon-free energy sources like the sun or wind has always been one of renewable power's major limitations, leaving us reliant on fossil fuels or nuclear power to supply the majority of so-called "baseload" power necessary to meet demand. A technology allowing for the storage of energy generated when the sun is shining or wind is blowing for later use could be a game-changer for the energy space, but cost and scalability often present significant challenges for such a project.

Is there a solution that allows for the large-scale storage of energy in order to improve the efficiency and environmental impact of power generation? The Energy Collective's latest webcast brings together a diverse group of professionals to explore this question, discuss existing technologies and those in development, and examine the opportunities available to integrate greater shares of clean energy into the electric grid.

Our panelists discussed:

  • The most promising storage technology ventures and their paths to market.
  • Existing and proven storage projects and the opportunity to build on success.
  • The obstacles to building storage solutions on an effective scale, and ways of addressing these challenges.
  • Whether large, grid-scale solutions, smaller, more distributed storage, or a combination of both offer the most effective strategy.
