Energy Storage – Introduction
Fundamental principle and very important characteristic of electricity:
‘Electricity cannot be stored directly as electrical energy unless converted into another form’
Supply Demand
Electricity
Severe Cost Implications
Excess Generation Capacity for Peak Loads
Reserve Generation Capacity to account for changes in the load or unplanned loss of a generator etc.

another form and stored.’

Chemical Energy (Batteries)
Kinetic Energy (Flywheels and CAES)
Gravitational Potential Energy (Pumped Hydro)
Others(Capacitors and Magnetic Fields)
Primary Drivers for Energy Storage:
Increase in peak demand and the need to respond quickly given constraints in generation and transmission capacity
Continuous need of high quality, reliable power
Integration of distributed and intermittent sources of RE
As we start to move away from fossil fuel based sources towards RE and overhauling our electricity infrastructure energy storage systems would play an increasingly important role!

Energy Storage – Applications
A wide variety of potential storage applications exist and depending on the application an appropriate technology needs to be chosen. Some key applications include –
Load Shifting: Refers to usage of energy stored during periods
of low demand for periods with high demand (production constant). During peak demand hours, stored energy is discharged to augment generation output or T&D capacity.
Mitigating Transmission Congestion: Holding onto the generated capacity until
transmission lines clear up (especially in cases where the generation is far from population centers)
Renewables Time Shifting: RE generation and demand do not match and
typically occur in different periods during day / year
Wind and solar depend on weather conditions Similar to load shifting

Energy Storage – Applications
A wide variety of potential storage applications exist and depending on the application an appropriate technology needs to be chosen. Some key applications include –
Spinning Reserve: Stored energy to compensate for unexpected
loss of generation resources Refers to stored energy that can be made
available immediately (i.e. very fast response time)
Off-grid: Off-grid consumers use fossil or RE sources
for their electricity Since these are variable in nature they need
to be complemented with storage solutions to fill gaps between supply and demand
Others: Regulation control Voltage support Etc.

Global Energy Storage Capacity(by technology)
Energy Storage Capacity: Pumped Hydro is the world’s most commonly used
storage technology with a global capacity of 140 GW (22 GW out of which are installed in the US).
Other popular storage technologies include CAES and various types of battery technologies

PUMPED HYDRO
Energy Storage – Technologies
Pumped Hydroelectric Storage (PHS) System: Most mature form of energy storage
Working Principle: A pumped hydroelectric energy storage system uses electricity to pump water to higher altitude where it
is stored as gravitational potential energy To generate electricity water is released and passed back through turbines/generator on its way to a
lower reservoir
Efficiency and Applications: PHS efficiency is between 75 and 85% Load Leveling and Peak Shaving

Compressed Air Energy Storage (CAES)
Compressed Air Energy Storage: Relatively mature form of energy storage
Working Principle: CAES system uses a compressor which uses low cost off-peak power to store energy as
compressed air inside an air-tight vessel The energy is converted back to electricity by reheating pressurized air. It is then passed through an
expansion turbine where it is combusted to drive an electric generator
Efficiency and Applications: Large CAES efficiency is 73 to 89% Load Shifting, regulation control, spinning reserve are some applications where CAES technology can
be used

Batteries: Widely used form of energy storage both in distributed and centralized systems
Working Principle: Use chemical reactions with two or more electrochemical cells to enable the flow of electrons Examples include – Lithium based batteries (lithium-ion etc.), Lead Acid based batteries, Sodium
Sulphur (NaS) amongst others
Applications: Grid Support and integration of intermittent renewables Consumer electronics

Utility Scale and Distributed Storage Global Project Profile –
Several utility scale energy storage projects have been operational and under construction. Below are a few examples:
Technology Type Project Name Country Description
Pumped Hydro Goldisthal Project
Germany Was fully commissioned in 2004. Its capacity of 1,060 MW makes it the largest hydroelectric power plant in Germany and one of the largest in Europe. Construction costs amounted to about € 623 million.
CAES Kraftwerk Huntorf
Germany 1st commercial CAES plant, operational since 1978. The 321-MW plant utilizes nuclear-sourced night-time power for compression and produces peak power during the day via a natural gas turbine. Recently used as a spinning reserve for industrial customers and to level power from wind energy.
Li-ion Battery Samsung SDI Project
South Korea
Samsung SDI installed 1MW/1MWh of Li-ion battery based energy storage system for industrial energy management with peak-shifting. The system is located at the Samsung SDI Headquarters in Yongin-Si, South Korea.

Several distributed energy storage projects are also being incentivized globally – For example Germany has introduced a subsidy mechanism for battery storage technology with Photovoltaics.

What does it mean for the MENA / GCC region?
Various GCC countries have embarked upon their plans to make renewable energy (solar, wind and other sources) a cornerstone of their future electricity mix.
Saudi Arabia: 54 GW of RE by 2032
• Solar PV – 16 GW• CSP – 25 GW
UAE: Both Dubai and Abu Dhabi have
launched tenders for two large-scale solar plants, each 100 MW.
Furthermore, Dubai plans to introduce a rooftop PV program to promote solar

Page 21
What does it mean for the MENA / GCC region?
Such ambitious RE plans will make solar and other sources of renewable energy an essential component of the energy mix thereby altering the energy mix of this region
Furthermore, it is estimated that the energy requirement of the region would only increase in the next years
WITHOUT APPROPRIATE ENERGY STORAGE SOLUTIONS IN PLACE, COMPLEX INTEGRATION ISSUES COULD ARISE –
A CASE WHICH SEVERAL EU NATIONS FACE TODAY
THEREFORE, THERE IS A NEED TO THINK AHEAD!
Such circumstances would require utilities in the region to think ahead to provide secure network for transmission of such intermittent energy –
