Q.4 Discuss the safety aspects associated with hydrogen energy storage. Explain the measures, regulations, and best practices implemented to ensure safe storage, handling, and transportation of hydrogen.

Q.5a) Compare different fuel cells based upon efficiency, operating temperature and fuel used.

b) What are the main components of a fuel cell? How does a fuel cell generate electricity?

Q.6 What are the factors need to be considered while designing PCM? What are the different applications of PCM?

Q.7 Explain the innovative strategies used for Thermal Solar Energy Storage in buildings to achieve 3E goals.

Q.8 Compare and contrast the capital costs and operational costs of pumped-storage hydroelectricity and lithium-ion battery storage systems. What factors contribute to the cost differences between these two technologies?Q.8 Compare and contrast the capital costs and operational costs of pumped-storage hydroelectricity and lithium-ion battery storage systems. What factors contribute to the cost differences between these two technologies?

Q.9 Discuss the economic viability of implementing sensible heat storage systems in different sectors. Analyze the factors that influence the cost- effectiveness and return on investment of such systems, considering both the initial capital costs and long-term operational benefits.

Q.10 a) What are the challenges or limitations associated with implementing LHTES systems?

b) Provide examples of real-world applications or case studies where LHTES systems have been successfully implemented.
