undeniable future of energy and mobility. However, each of these have their share of limitations. Electric vehicles come with batteries that do not last beyond a decade, and solar plants suffer from intermittence due to the day-night and seasonal cycles.<\/p>\n<p>However, a study by an MIT team might be able to tackle both problems with a single solution. A <a href=\"https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S0306261920306395\" target=\"_blank\" rel=\"noopener\">paper<\/a> by the researchers titled \u2018Technoeconomic model of second-life batteries for utility-scale solar considering calendar and cycle aging\u2019, shows promising economics for giving EV batteries a second life. They achieved these results by working on a hypothetical solar plant model that uses new batteries vs used EV batteries.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What-It-Means-for-the-Respective-Sectors\"><\/span>What It Means for the Respective Sectors<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The researchers were aware beforehand that used EV batteries would suit the solar plants even after being deemed unusable for electric vehicles themselves. The reason for this is that solar plants do not demand as rigorous and as uneven performance from batteries like vehicles do.<\/p>\n<p>With every passing year, both the installed capacity of solar and the number of EVs on roads is increasing at a rapid rate.<\/p>\n<p>As time passes, solar power will replace more and more conventional power. But one of the obstacles in a total reduction of fossil-based power is the reliance of solar plants on conventional grid power for <a href=\"https:\/\/ecotality.com\/can-solar-panels-work-at-night\/\">dark hours<\/a>.<\/p>\n<p>On the other hand, as EVs multiply, there will soon be a multitude of used batteries posing questions on disposal and lifetime costs incurred.<\/p>\n<p>The ability to use end-of-life EV batteries in solar plants means an economic boom as well as a technical solution to the cost and intermittence problem. As <a href=\"https:\/\/ecotality.com\/the-rise-of-solar-microgrids\/\">solar plants evolve to suit communities<\/a> independently, this could be an important milestone.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Approach-Used-in-the-Study\"><\/span>Approach Used in the Study<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>This team of current and former researchers of the Massachusetts Institute of Technology analyzed a virtual 2.5MWp located in California. They studied the economics of multiple scenarios:<\/p>\n<ol>\n\t<li>Building just the 2.5 MW solar plant,<\/li>\n\t<li>Building the plant with new lithium-ion battery system, and<\/li>\n\t<li>Building the plant with used EV batteries toward their life\u2019s end<\/li>\n<\/ol>\n<p>As expected, the plant with new battery bank showed the least promising net return on the investment.

The only catch is that the battery prices should be lower than 60% of their original cost, which does not seem to be a big challenge.<\/p>\n<p>However, it is not as straightforward as it sounds, according to researcher Ian Matthews. There might still be some challenges associated with this approach, primarily that of screening the batteries. But for now, the modeled case provides excellent results for the location of California and should possibly also work for many other parts of the world.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-adaee28 references-section elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"adaee28\" data-element_type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-fae992a\" data-id=\"fae992a\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t\t\t<div class=\"elementor-element elementor-element-63ba581 references-heading elementor-widget elementor-widget-heading\" data-id=\"63ba581\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h4 class=\"elementor-heading-title elementor-size-default\">References<\/h4>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-2c63eaf references elementor-widget elementor-widget-text-editor\" data-id=\"2c63eaf\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<ol>\n<li><a href=\"https:\/\/www.energy.gov\/eere\/solar\/articles\/solar-plus-storage-101\" target=\"_blank\" rel=\"nofollow noopener\">Solar Plus Storage 101<\/a> &#8211; US Department of Energy<\/li>\n<li><a href=\"https:\/\/www.edfenergy.com\/electric-cars\/batteries#:~:text=Electric%20car%20battery%20technology&amp;text=This%20decreases%20the%20range%20and,they%20need%20to%20be%20replaced.\" target=\"_blank\" rel=\"nofollow noopener\">All About Electric Car Batteries<\/a> &#8211; EDF<\/li>\n<li><a href=\"https:\/\/www.irena.org\/documentdownloads\/publications\/re_technologies_cost_analysis-solar_pv.pdf\" target=\"_blank\" rel=\"nofollow noopener\">Renewable Energy Cost Analysis<\/a> &#8211; IRENA<\/li>\n<\/ol>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-513533f post-rating-section elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"513533f\" data-element_type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-72f6be6\" data-id=\"72f6be6\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t\t\t<div class=\"elementor-element elementor-element-f32531a post-rating elementor-widget elementor-widget-shortcode\" data-id=\"f32531a\" data-element_type=\"widget\" data-widget_type=\"shortcode.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div class=\"elementor-shortcode\"><!-- Rate my Post Plugin --><div  class=\"rmp-widgets-container rmp-wp-plugin rmp-main-container js-rmp-widgets-container js-rmp-widgets-container--14656 \"  data-post-id=\"14656\">    <!-- Rating widget -->  <div class=\"rmp-rating-widget js-rmp-rating-widget\">          <p class=\"rmp-heading rmp-heading--title\">        We hope you liked this article.
