Pumped Hydro Storage is a type of mechanical energy storage, not thermal energy storage.

What is the primary advantage of using Sensible Heat Storage systems?

  1. High energy density

  2. Low cost

  3. Long-term energy storage

  4. High efficiency

Show answer
Correct Option: B
Explanation:

Sensible Heat Storage systems are relatively inexpensive to install and maintain compared to other TES technologies.

Which material is commonly used for storing thermal energy in Latent Heat Storage systems?

  1. Water

  2. Ice

  3. Molten Salt

  4. Phase Change Materials (PCMs)

Show answer
Correct Option: D
Explanation:

Phase Change Materials (PCMs) are substances that undergo a phase change (e.g., solid to liquid) during thermal energy storage and release.

What is the main advantage of using Thermochemical Storage systems?

  1. High energy density

  2. Long-term energy storage

  3. High efficiency

  4. Low maintenance

Which of the following is NOT a potential application of Thermal Energy Storage (TES) systems in industrial processes?

  1. Waste heat recovery

  2. Load leveling

  3. Process heating and cooling

  4. Backup power generation

Show answer
Correct Option: D
Explanation:

Backup power generation is typically provided by generators or batteries, not Thermal Energy Storage systems.

What is the primary challenge associated with using Phase Change Materials (PCMs) in Thermal Energy Storage (TES) systems?

  1. High cost

  2. Low energy density

  3. Limited temperature range

  4. All of the above

Show answer
Correct Option: C
Explanation:

Phase Change Materials (PCMs) have a limited temperature range within which they undergo phase change, which can limit their applicability in certain TES systems.

Which of the following is NOT a potential benefit of using Thermal Energy Storage (TES) systems in district heating and cooling applications?

  1. Reduced energy costs

  2. Improved energy efficiency

  3. Increased grid stability

  4. Increased greenhouse gas emissions

Show answer
Correct Option: D
Explanation:

Thermal Energy Storage systems help reduce greenhouse gas emissions by storing energy from renewable sources and reducing the need for fossil fuel-based generation.
