Question 1:
What is one of the major challenges of energy storage technologies?
Explanation: The correct answer is B) High cost of implementation. One of the major challenges of energy storage technologies is their high cost of implementation. Developing and deploying efficient and reliable energy storage systems can be expensive, making it a barrier for widespread adoption. However, ongoing research and technological advancements are expected to drive down costs and make energy storage more economically viable in the future.
Question 2:
Which of the following is a potential future innovation in energy storage?
Explanation: The correct answer is B) Flow batteries. Flow batteries are a potential future innovation in energy storage. Unlike traditional batteries where energy is stored in solid electrodes, flow batteries store energy in liquid electrolytes contained in external tanks. Flow batteries offer advantages such as scalability, longer duration storage, and the ability to decouple power and energy capacity. These features make flow batteries promising for large-scale energy storage applications.
Question 3:
What is one of the challenges associated with the integration of renewable energy sources and energy storage?
Explanation: The correct answer is D) Challenges in integrating intermittent energy generation with storage. One of the challenges associated with the integration of renewable energy sources and energy storage is the intermittent nature of renewable energy generation. Renewable sources like solar and wind energy are dependent on weather conditions and may produce power intermittently. Energy storage systems can help address this challenge by storing excess energy during periods of high generation and supplying it during low generation periods. This enables a more reliable and consistent supply of renewable energy to the grid.
Question 4:
Which technology offers the potential for long-duration energy storage?
Explanation: The correct answer is C) Pumped hydro storage. Pumped hydro storage is a technology that offers the potential for long-duration energy storage. It involves using excess energy during low demand periods to pump water from a lower reservoir to an upper reservoir. When energy is needed, the stored water is released, flowing downhill through turbines to generate electricity. Pumped hydro storage can store and deliver large amounts of energy for several hours or even days, making it well-suited for balancing daily and seasonal variations in energy supply and demand.
Question 5:
What is a key consideration for future energy storage innovations?
Explanation: The correct answer is B) Enhancing energy storage efficiency. One key consideration for future energy storage innovations is to enhance energy storage efficiency. Improving the efficiency of energy storage systems allows for a greater proportion of stored energy to be utilized without significant losses. This can lead toimproved overall system performance, reduced costs, and increased sustainability. Energy storage efficiency improvements can involve advancements in materials, design, control systems, and integration with renewable energy sources. Enhancing energy storage efficiency is crucial for maximizing the value and effectiveness of energy storage technologies in supporting a reliable and sustainable energy system.
