In
a first, India plans standalone renewable battery power bank { Times of
India / 17 April 2022 }
Extract :
India is setting up a first-of-its-kind standalone renewable battery
power bank envisaging an investment of Rs 2,000 crore to make green energy available on tap for discoms and
grid operators during peak demand, but
spike in prices of lithium — a key ingredient for making batteries — and supply
chain disruptions due to the Russia-Ukraine conflict may weigh on industry
response.
According to the tender floated by SECI ( formerly Solar Energy
Corporation of India Ltd ),
the government entity implementing India’s solar and wind energy plans, earlier
this week, the project will have storage capacity to supply 500MW
for two hours, or 1,000MWh (mega watt
hour), the renewable energy ministry said in a statement on Saturday.
Discoms can hire storage capacity, which will be charged using renewable energy, and draw power to manage peak demand. The project is to be located
in the vicinity of the Fatehgarh-III substation of the interstate transmission
system in Rajasthan.
The project will be set up on a build-own-operate
basis, with the developer being
responsible for securing
connectivity and necessary permissions.
Land will be provided by the central transmission utility on a
right-to-use basis. The developer has to make storage capacity available for
two operational cycles per day, or two complete charge-discharge cycles a day.
SECI will off take 60% capacity for third-party
leasing, while 30% will be earmarked by northern and national grid operators
for their ancillary services. But industry representatives said the project’s
success will depend on viability gap
funding from the Centre, especially since 500% increase in lithium
prices has made batteries expensive and will push up
power tariff unviable for entities’ leasing capacity.
But the ministry statement said the project is
aimed at providing support for developing a market in the energy storage domain.
Currently, India is considered a low-priority market by global battery
makers, who are focusing on the US and Europe that are focused on storage-based
renewable energy projects.
However, industry representatives said the timing
may not be ideal because of the uncertain geopolitical situation in east
Europe, which has effected global trade and jacked up commodity prices.
The government has set a target of 4,000 MWh of battery storage capacity as part of the plan to increase penetration of
renewable energy in the national grid.
A Central Electricity
Authority report on optimal generation capacity mix envisages a battery storage capacity of 27,000
MW, or 108,000 MWh — essentially four-hour storage — by 2029-30.
MY TAKE :
Ø Solar
Power –Thermal Power – Storage Battery [ 26 Nov

Extract :
Ministry of New and Renewable Energy –
MNRE - is examining a proposal submitted by the Power Grid Corporation of India ,
to generate Solar and Wind power in the deserts of Rajasthan / Kutchh / Lahul and Spiti / Ladakh
These deserts have, between them , the potential to generate 315.7 GW of Solar plus Wind power,
compared with our present installed capacity of 331 GW
But , how to “ Store “
all that huge amount of Solar generated electricity and use it round the clock
when Sun is not shining ?
This ( storage of solar generated
power ) was not possible till yesterday
But it just became possible !
Only yesterday , Elon Musk ( TESLA )
completed installation of a 100 MW /
129 MWh , Lithium-ion Battery Storage
facility in Australia , for a cost of $ 50 million
All within 100 days – ensuring no
more “ black outs “ in South Australia !
To store that 316 GW ( 316,000 MW ) of solar power
generated in our deserts , we will need 3160
Storage Batteries of the size ( 100 MW ) installed in Australia
That would cost , $ 158 Billion ( Rs 11.15 lakh*crore )
In all , we need to raise :
# For 316 GW solar power projects in our deserts…………$ 316 Billion
# For
3160 Mega Storage Batteries………………………………..$ 158 Billion
Total
of ………………………………………………………………………… $
474 Billion
Dear Shri R K Singhji
( Minister – MNRE ) :
Above cost estimates are extrapolated from TESLA’s 4 year old installation in
Australia . In normal course, after a passage of 4 years, one would expect the
costs to come down .
However given 500 % increase in Lithium prices, the GRID SCALE BATTERY
STORAGE costs must have gone up drastically. Viability Gap Funding seems out of
the question
In view
of this, I urge you to consider the following alternatives :

THE BATTERY CYCLE
·
The basic principle of operation is reversible rusting
·
While
discharging, the battery breathes in oxygen from the air and converts iron metal to rust
·
While
charging, the application of an electrical current converts
the rust back to iron and the battery breathes
out oxygen
OUR
MODULAR, SCALABLE MULTI-DAY STORAGE SYSTEM
Each individual battery is
about the size of a
washing machine.
Each of these modules is
filled with a water-based, non-flammable electrolyte,
similar to the electrolyte used in AA batteries.
Inside of the liquid
electrolyte are stacks of between 10 and 20 meter-scale cells, which
include iron electrodes and air electrodes, the parts of the battery that enable
the electrochemical reactions to store and discharge
electricity.
These battery modules are grouped together in modular megawatt-scale power blocks, which comprise thousands of
battery modules in an environmentally protected enclosure.
Depending on the system
size, tens to hundreds of
these power blocks will be connected to the electricity grid.
For scale, in its least
dense configuration, a one megawatt system requires
about an acre of land. Higher density configurations can achieve
>3MW/acre.
Our battery systems can be
sited anywhere, even in urban areas, to meet utility-scale energy needs.
Our batteries complement
the function of lithium-ion batteries, allowing for an optimal balance of our
technology and lithium-ion batteries to deliver the lowest-cost renewable and
reliable electric system year-round.
