Attempt all the questions:
Q.1 What are the
challenges and opportunities associated with integrating energy storage systems
into the electrical grid?
Cost: The
upfront cost of energy storage systems can be high, although it has been
decreasing over time. The initial investment might deter widespread adoption,
especially in regions with limited financial resources.
Technology:
Developing reliable and efficient storage technologies that can handle
large-scale grid applications is a significant challenge. Battery technologies,
for instance, must improve in terms of energy density, cycle life, and safety.
Regulatory
Hurdles: Existing regulatory frameworks may not adequately address the
integration of energy storage into the grid. There may be barriers related to
market structure, tariffs, and interconnection standards that need to be
addressed to facilitate integration.
Intermittency:
Renewable energy sources, such as solar and wind, are intermittent, meaning
their output varies based on weather conditions. Energy storage can help
mitigate this intermittency by storing excess energy generated during peak
production periods for use when energy generation is low. However, balancing
supply and demand in real-time remains a challenge.
Siting and
Permitting: Identifying suitable locations for energy storage installations and
obtaining the necessary permits can be challenging. Environmental concerns,
land use conflicts, and community opposition may arise, particularly for
large-scale projects.
Grid Stability
and Reliability: Energy storage systems can enhance grid stability by providing
ancillary services such as frequency regulation, voltage support, and grid
balancing. This improves the overall reliability of the electrical grid,
reducing the risk of blackouts and brownouts.
Integration of
Renewables: Energy storage facilitates the integration of renewable energy
sources into the grid by storing excess energy generated during periods of high
production and releasing it during times of high demand or low renewable
generation. This helps reduce reliance on fossil fuels and accelerates the
transition to a cleaner, more sustainable energy system.
Peak Shaving
and Demand Response: Energy storage systems can help utilities manage peak
demand by storing energy during off-peak hours when electricity is cheaper and
supplying it during peak hours when electricity prices are higher. This can
lead to cost savings for both utilities and consumers and alleviate strain on
the grid during periods of high demand.
Grid
Modernization: Integrating energy storage into the grid enables grid
modernization efforts by enhancing grid flexibility, enabling the integration
of distributed energy resources, and supporting the development of smart grid
technologies. This leads to a more resilient, efficient, and adaptable
electrical grid infrastructure.
Energy
Independence: Energy storage systems can provide backup power during outages,
reducing dependence on centralized power plants and enhancing energy
independence at the local level. This is particularly beneficial in remote
areas or regions prone to extreme weather events.
Q.2 Explain the design
considerations for a flywheel rotor, including material selection, shape, and
balancing techniques. Discuss the factors that affect the maximum achievable
energy storage capacity.
Q.3 Discuss the
concept of redox flow batteries and their advantages over other battery technologies.
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.5 a) 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.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.
