Energy storage
• Energy storage will soon become an essential element
of the smart grid
• Especially as more power generation from inherently
intermittent sources such as solar and wind come online.
• In some markets, there may also be value for companies
to buy and store power when it is least expensive, and
use the stored power during peak demand when prices
are highest (arbitrage).

• Electric energy storage systems are crucial for the
further development the sectors, including:
o Renewable energy,
o Automotive,
o Grid stabilization,
o Smart grid,
o Back-up power.
• The two main applications of energy storage
technologies are:
o Power-driven by the needs for power quality
o Bridging power-and for energy management.

• The most important drivers for developing electric energy
storage systems are grid stability and reliability
• “Electric energy storage technologies will be an
inseparable part of smart grids and distributed energy
generating systems in the future.”
• Reliable and durable electric energy storage technologies
will enhance the usage and commercial attractiveness of
energy sources, such as wind and solar power.

• Among the various electric energy storage systems,
advanced batteries are set to attract the greatest interest
in the near future.
• This is because of their flexibility in use, in grid balancing
and connecting intermittent renewable energy
generators to the main electric grid.
• Frost & Sullivan research reveals that lithium-ion
batteries will play the most important role in the future of
electric energy storage systems.
• Fuel cells, could also be used for energy storage.

• Before electric energy storage technology can be
adopted on a mass scale, certain technical problems
need to be resolved.
• For instance: o Focused on developing new chemistry that will optimize battery
durability and energy density.
o Reduce the time needed for battery recharging
• find solution is likely to encourage widespread adoption
of battery technology by the automotive and electric grid
industries.

Solar is not available when you want it, but it's
available when you need it.
• The need for energy storage will also be driven by
nature of many renewable energy sources, such as solar
power and wind.
• Solar is generating in a very high correlation when the
grid is needing power.
• Reality is when the demand is the highest.
• A typical application is load leveling, which involves
charging storage when energy cost is low and using
the stored energy as needed..
