Review Questions

• How do energy storage systems improve the integration of renewable energy sources into the power grid?
  • Energy storage systems improve the integration of renewable energy sources by capturing excess electricity generated during peak production times, such as sunny or windy days. This stored energy can then be released during periods of high demand or low generation, ensuring a continuous supply of electricity. By smoothing out fluctuations in renewable generation, these systems help stabilize the grid and enhance overall reliability.
• Evaluate the role of various types of energy storage systems in addressing the challenges posed by intermittent renewable energy sources.
  • Various types of energy storage systems, including batteries, pumped hydro storage, and thermal storage, each play a unique role in addressing challenges posed by intermittent renewable energy sources. For instance, batteries provide rapid response times for balancing short-term fluctuations in supply and demand, while pumped hydro offers large-scale storage capabilities over longer durations. Thermal storage can shift energy use from peak times to off-peak periods. By combining these technologies, we can create a more resilient and adaptable energy system.
