Millions
of EV Batteries Could Retire to Solar Farms
………. Wired . 25 Nov 2023
Extract :
The SEPV
Cuyama facility, located about two hours northeast of Santa Barbara, is the
second hybrid storage facility opened by B2U Storage Solutions. Its first facility, just outside Los
Angeles, uses 1,300 retired batteries from Honda
Clarity and Nissan Leaf EVs to store 28 megawatt-hours of power, enough to
power about 9,500 homes.
The
facilities are meant to prove the feasibility of giving EV
batteries a second life as stationary storage before they are
recycled. Doing so could increase the sustainability of the technology’s supply
chain and reduce the need to mine critical minerals, while providing a cheaper
way of building out grid-scale storage.
Electric vehicle batteries are typically replaced when they reach 70 to
80 percent of their capacity, largely because the range
they provide at that point begins to dwindle.
Before they are disassembled, however, studies show that around
three-quarters of decommissioned packs are suitable for a second life as
stationary storage
The use of utility-scale battery storage is expected to skyrocket, from 1.5 gigawatts of capacity in 2020 to 30 gigawatts
by 2025.
EV packs could provide a stockpile for that buildout.
Hall said there are already at least 3 gigawatt-hours of
decommissioned EV packs sitting
around in the United States that could be deployed, and that the volume of them being
removed from cars is
doubling every two years
B2U says its technology
allows batteries to be repurposed in a nearly “plug-and-play fashion.” They do not need to be disassembled, and units from multiple manufacturers—B2U has tested batteries from
Honda, Nissan, Tesla, GM, and Ford—can be used in one system.
The batteries charge during
the day from both the solar panels and the grid. Then B2U sells that power to
utilities at night, when demand and prices are much higher.
Hall said using second-life
batteries earns the same financial return as new grid-scale batteries at half the initial cost, and that for now, repurposing the packs is more lucrative for automakers than sending them
straight to recyclers
By selling or leasing retired
packs to a grid storage company, said Hall, manufacturers can squeeze more
value out of them.
At the moment, though,
planned deployment of the technology is limited. B2U predicts only about 6
percent of decommissioned EV batteries in the US will be used for grid-scale
storage by 2027.
Dear Shri R K Singhji ,
I am sure the article cited
above , would interest you , given our desire to achieve GRID scale Battery
Storage capacity, as reported in :
Grid-scale
storage can play vital role in boosting India’s renewable energy transition
Extract :
“ Around 34 gigawatts (GW) or 136 gigawatts per hour (GWh) of battery energy storage system is expected to be installed in India by 2030, according to a report by the Central Electricity Authority (CEA). “
While you may examine the possibility to allow import of USED BATTERY PACKS from USA / EU , with
NIL import
duty for GRID scale battery storage , I urge you to also consider the possibility of using this “ EV retired
packs “ for smaller batteries required for powering SOLAR
COOKERS

Energy
Efficient Fans Programme launched, One crore energy-efficient fans to be
distributed in initial phase
“E-Cooking
will reduce cooking costs of poor families”:
Union Minister
for Power and New & Renewable Energy, exhorting EESL to
“do with the cooking stove what
you did with the LED”
Energy
Efficiency Services Limited (EESL), a joint venture of Public Sector
Undertakings under Ministry of Power, launched its ground breaking National Efficient
Cooking Programme (NECP) and
Energy Efficient Fans Programme (EEFP) today, unveiled by the Union Minister
for Power and New & Renewable Energy Shri R. K. Singh, at an event held in
New Delhi today, November 2, 2023.
These
initiatives are aimed at revolutionizing
cooking practices in India and emphasizing
on the importance and urgency of energy efficient fans.
As part of these
programmes, EESL will distribute 1 crore efficient BLDC fans and 20 Lakh energy-efficient induction cook stoves nationwide.
The National
Efficient Cooking Programme (NECP) introduces induction-based
cook-stoves, offering a cost advantage of 25-30% over traditional cooking
methods, promising both energy savings and cost-effective
cooking solutions.
By deploying 20 Lakh Induction
cook-stoves across India, EESL seeks
to reduce the environmental impact of cooking methods, ensuring cleaner air and improved health
for citizens.
EESL has also
partnered with Modern Energy Cooking Services (MECS) for the large-scale
deployment of induction cooktops. The deployment is expected to accelerate the
acceptance and large-scale adoption of modern electric cooking devices in
Indian kitchens.
“Electric
Cooking is one way to reduce dependence on imported sources for energy”
Addressing the
gathering comprising the proud officials of EESL and others, the Union Power
& NRE Minister underlined the strategic imperative due to which a shift
towards electric cooking is necessary. “We have cooking based on imported
Liquified Natural Gas. We can afford it financially, but in strategic terms, it is not
advisable to depend on other countries for energy needs. This is one reason we need to shift
from imported sources of energy to indigenous forms; and one way to do that is
to shift our cooking to electricity.”
The Minister
stressed that there is no difference in food cooked on flame versus that cooked
using induction cookers. “We need to propagate this; all organizations under
Ministry of Power and Ministry of New & Renewable Energy will help in
propagating this, all organizations will get together to bring to every
household the advantages of shifting
to electric cooking, in terms of price and availability.”
Shri Singh
explained how a shift to electric cooking will help the ordinary citizen. “Even
though we subsidize our gas cylinders, many
poor families are not able to afford buying gas cylinders. So, this brings us back to cooking based on fossil
fuels. Electric cooking,
I believe, is the answer to this problem; especially for poor consumers, if
they switch over to electric cooking, it will reduce their cooking costs, after
accounting for cost of electricity as well.”

Upon consulting BARD re; use of “ Second Life
Decommissioned EV Battery Packs “ for powering Solar Cookers , here is
what it said :
Dear Hemen,
Thank you for sharing your blog post
with me. I found it to be a well-informed and thought-provoking
piece on the feasibility of using "second life" EV batteries for solar cookers.
I believe that your proposal has
the potential to be a viable and sustainable solution for providing affordable
and clean cooking energy to households in India.
The use of second-life batteries
could significantly
reduce the cost of solar cookers, making
them more accessible to a wider range of people. Additionally, repurposing
these batteries would help to extend their lifespan and reduce the
environmental impact of EV battery disposal.
Of course, there are some challenges
that would need to be addressed in order to implement this proposal
successfully. One challenge is that the capacity and performance of second-life batteries may vary depending on their age and
usage. This could make it difficult to design a standardized solar cooker that
is compatible with all types of second-life batteries.
Another challenge is that the safety of second-life batteries would need to be carefully evaluated
before they are used in solar cookers. Improper handling or storage of these
batteries could pose a fire or explosion hazard.
Despite these challenges, I believe
that the potential benefits of using second-life batteries for
solar cookers outweigh the risks.
With careful planning and
implementation, this proposal could make a significant
contribution to the development of a cleaner and more sustainable energy future
for India.
Here are some additional thoughts on
the feasibility and desirability of your suggestion:
·
Feasibility:
o
The technology
to repurpose EV batteries for solar
cookers is already available, as demonstrated by the companies
mentioned in your blog post.
o
The cost of second-life batteries is likely to be lower than the cost of new batteries, which
would make solar cookers more affordable.
o
There is a
growing demand for solar cookers in India, as people become more aware of the
environmental and health benefits of using clean cooking energy.
·
Desirability:
o
Repurposing
EV batteries for solar cookers would help to reduce the environmental impact of EV battery disposal.
o
Using
solar cookers would help to reduce air
pollution and improve indoor air quality.
o
Solar
cookers can be used in areas where there is no access to electricity or LPG.
I encourage you to continue to
research and advocate for this proposal.
I believe that it has the
potential to make a real difference in the lives of millions of people in India.
Sincerely, Bard
