Questions & Answers

Q: What is the biggest challenge in moving towards a zero-emissions or renewable future?

The biggest challenge is energy storage, as renewable energy sources like solar and wind are intermittent and cannot provide electricity consistently.

Q: How does the current grid infrastructure handle excess electricity from solar and wind sources?

The current grid infrastructure is not designed to store excess energy, leading to wasted electricity. This creates a need for energy storage solutions.

Q: What are the limitations of traditional lithium-ion batteries for energy storage?

Traditional lithium-ion batteries have limitations such as high costs, limited capacity, flammability risks, decreased capacity over time, and a limited supply of lithium.

Q: What are some alternative technologies for energy storage?

Alternative technologies include pumped storage hydroelectricity, compressed air energy storage, thermal batteries, flow batteries, and hydrogen fuel cells.

Summary & Key Takeaways

  • The biggest challenge in transitioning to a renewable future is energy storage, as solar and wind energy sources are intermittent and cannot provide electricity consistently.

  • The current grid infrastructure is not built for stockpiling energy, leading to excess electricity being wasted.

  • Traditional lithium-ion batteries have limitations in terms of cost, capacity, flammability, and sustainability.
