Webinar abstract: 

Battery storage remains a competitive and popular storage option among today’s power system technologies. However, what can utilities and grid operators expect batteries to cost in the coming decades and how will this technology likely evolve to meet market needs in the future?

As the energy sector makes the transition to integrate renewables, long-term storage will also play a vital role in allowing thermal generation to managing variability in supply and demand.

This session will also include discussions about the need for compressed air, liquified air and other long-term storage options as we accelerate the decarbonization energy transition.

Key takeaways:               

  • What are the different storage applications and technologies that will play a role?
  • What are the strengths and weaknesses of each?
  • How is it going to be integrated? 

Objective:  Educate decision makers around fuels and power sources.

Audience:  Policy makers, industry experts, local utilities and consultants
