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

National Efficient Cooking Programme launched, to promote affordable and energy-efficient induction cookers – EQ  ……….. 03 Nov 2023

Extract :

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
