Unlike traditional lithium-ion batteries, the lithium iron phosphate variety is made with non-toxic materials. The battery composition is also inherently safer and more stable than lithium-ion batteries. The composition also virtually eliminates environmental concerns of disposal since the batteries consist of non-toxic materials. The materials can also be reused and recycled, promoting a circular economy of lithium-ion batteries.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"cqColumns containsResourceName section resourceClass-columns\">\n<div class=\"row add_margin_50 add_margin_50_xs\">\n<div class=\"col-xs-12\">\n<div class=\"2a73297d-9b42-4329-91c9-01484f11c9e3 parsys containsResourceName resourceClass-parsys\">\n<div class=\"text containsResourceName section resourceClass-text\">\n<div class=\"mw-text\">\n<p>Hydro-Qu\u00e9bec has been developing the technology behind the EVLO systems for the past 40 years. Its smaller systems can power commercial buildings, while the larger, ruggedized units can power grids and industrial sites. The lithium iron phosphate battery ranks among the most efficient batteries on the market today. Unlike other battery types, it has a depth of discharge of 100%, meaning users can access all the energy stored in the battery.<\/p>\n<p>Adile Ajaja, the software team lead at EVLO, and his team use MATLAB<sup>\u00ae<\/sup><span>\u00a0<\/span>and Simulink<sup>\u00ae<\/sup><span>\u00a0<\/span>to develop and model the EVLO systems. They then use code generated from their Simulink models in their hardware to control the system.<\/p>\n<p>Since its first project, EVLO has brought its solution to other communities. In the town of Lac-M\u00e9gantic, the company recently installed an energy storage system to service a neighborhood microgrid. The first microgrid in Qu\u00e9bec was part of the recovery effort after a runaway train destroyed much of the downtown area a few years ago.<\/p>\n<p>EVLO stepped in as part of that project to increase the resiliency of the electric grid. The systems store the energy from 1,700 solar panels, servicing 40 buildings in the city center, electric vehicle charging stations, and automation controls for more efficient energy management. The microgrid and energy storage systems also provide a power source if the main grid goes out. \u201cWhen the distribution grid goes out for a planned or unplanned event, the microgrid that we have there will be self-sustainable and provide continuity of electricity,\u201d says Ajaja.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"cqColumns containsResourceName section resourceClass-columns\">\n<div class=\"row\">\n<div class=\"col-xs-12\">\n<div class=\"9cec90bf-695d-4a86-8167-1261c454b1fb parsys containsResourceName resourceClass-parsys\">\n<div class=\"text containsResourceName section resourceClass-text\">\n<div class=\"mw-text\">\n<h3>Removing Friction<\/h3>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"cqColumns containsResourceName section resourceClass-columns\">\n<div class=\"row\">\n<div class=\"col-xs-12 col-md-7\">\n<div class=\"9cec90bf-695d-4a86-8167-1261c454b1fb parsys containsResourceName resourceClass-parsys\">\n<div class=\"text containsResourceName section resourceClass-text\">\n<div class=\"mw-text\">\n<p>The Finland-based startup<span>\u00a0<\/span><a href=\"https:\/\/www.teraloop.org\/\" target=\"_blank\" rel=\"noopener\">Teraloop<\/a><span>\u00a0<\/span>has put a new spin on old energy storage technology.

Their product moves faster than standard flywheels, storing more energy.<\/p>\n<p>The company plans to use their flywheel to accompany battery storage at electric vehicle (EV) charging stations, for regenerative braking in subway and tram systems, and to stabilize microgrid voltage fluctuations.<\/p>\n<p>At EV charging stations, flywheels speed up vehicle charging and extend battery life. The batteries store energy from the grid for EV charging, but they\u2019re an imperfect solution. \u201cToday\u2019s batteries are lithium-ion and are not made to complete a lot of cycles every day. Their life goes down dramatically,\u201d says Hagerman. \u201cSo, you do what\u2019s called hybrid energy storage, which is the flywheel plus the battery.\u201d<\/p>\n<p>The hybrid storage model is good for the battery. \u201cIt protects the battery and allows the energy station to have a minimal grid connection,\u201d he says. That means that incorporating charging stations won\u2019t require grid upgrades, at least not while EVs are in the minority of vehicles on the road.<\/p>\n<p>As a standalone system, the flywheel can provide energy for public transportation systems. Regenerative braking technologies\u2014which reverse the rotation of a motor while braking to charge an electric vehicle\u2014are used in metros and trams but with limited storage capacity. \u201cAs long as you need high power for a short duration, like the acceleration of a subway \u2026 a flywheel can outperform batteries,\u201d says Hagerman.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"col-xs-12 col-md-5\">\n<div class=\"18897323-014e-432d-8828-20872c7d83dd parsys containsResourceName resourceClass-parsys\">\n<div class=\"cqImage containsResourceName section resourceClass-image\">\n<div class=\"clearfix mw-image thumbnail add_margin_0\">\n<p><img decoding=\"async\" src=\"https:\/\/uk.mathworks.com\/company\/mathworks-stories\/storage-solutions-for-renewable-energy\/_jcr_content\/mainParsys2\/columns_663673900\/835f3930-8ec3-4753-ad0a-8797c37eebc7\/columns_320727814_co\/18897323-014e-432d-8828-20872c7d83dd\/image_copy_copy.adapt.full.medium.jpg\/1658737331447.jpg\" alt=\"View of the Teraloop flywheel from above.\" width=\"456\" height=\"608\" sizes=\"auto, 100vw\" loading=\"lazy\" class=\"responsiveImage remove_border\" srcset=\"https:\/\/uk.mathworks.com\/company\/mathworks-stories\/storage-solutions-for-renewable-energy\/_jcr_content\/mainParsys2\/columns_663673900\/835f3930-8ec3-4753-ad0a-8797c37eebc7\/columns_320727814_co\/18897323-014e-432d-8828-20872c7d83dd\/image_copy_copy.adapt.150.medium.jpg\/1658737331447.jpg 150w, https:\/\/uk.mathworks.com\/company\/mathworks-stories\/storage-solutions-for-renewable-energy\/_jcr_content\/mainParsys2\/columns_663673900\/835f3930-8ec3-4753-ad0a-8797c37eebc7\/columns_320727814_co\/18897323-014e-432d-8828-20872c7d83dd\/image_copy_copy.adapt.320.medium.jpg\/1658737331447.jpg 320w, https:\/\/uk.mathworks.com\/company\/mathworks-stories\/storage-solutions-for-renewable-energy\/_jcr_content\/mainParsys2\/columns_663673900\/835f3930-8ec3-4753-ad0a-8797c37eebc7\/columns_320727814_co\/18897323-014e-432d-8828-20872c7d83dd\/image_copy_copy.adapt.480.medium.jpg\/1658737331447.jpg 480w, https:\/\/uk.mathworks.com\/company\/mathworks-stories\/storage-solutions-for-renewable-energy\/_jcr_content\/mainParsys2\/columns_663673900\/835f3930-8ec3-4753-ad0a-8797c37eebc7\/columns_320727814_co\/18897323-014e-432d-8828-20872c7d83dd\/image_copy_copy.adapt.620.medium.jpg\/1658737331447.jpg 620w, https:\/\/uk.mathworks.com\/company\/mathworks-stories\/storage-solutions-for-renewable-energy\/_jcr_content\/mainParsys2\/columns_663673900\/835f3930-8ec3-4753-ad0a-8797c37eebc7\/columns_320727814_co\/18897323-014e-432d-8828-20872c7d83dd\/image_copy_copy.adapt.full.medium.jpg\/1658737331447.jpg 675w\" data-aem-src=\"\/content\/dam\/mathworks\/mathworks-dot-com\/images\/responsive\/supporting\/company\/collections\/energy-storage\/energy-storage-teraloop-flywheel.jpg\" \/><\/p>\n<div class=\"caption\">\n<p>The Teraloop flywheel.

The hot salt and cold coolant are stored in separate tanks, storing 10 hours\u2019 worth of energy for several days.<\/p>\n<p>Then, when power is needed, a heat engine converts the thermal energy back into electrical energy for distribution. Based on power demands, an algorithm governs both when the system takes energy from the grid and when it distributes it. This cycle can repeat itself thousands of times: Malta estimates that the system can last for more than 25 years without major performance degradation.<\/p>\n<p>But the system is still being engineered and in the design phase of development. For now, the Malta team works in simulations. Importing a model of their system into Simulink, the Malta team designs the system controls and figures out how to operate their system. \u201cOur goal is to build a plant in the coming years. Because we don\u2019t have a plant now, the best thing we can do is build simulation models and run a bunch of tests on it,\u201d says Vinnakota. \u201cWe\u2019re also using Model-Based Design to determine the plant specifications based on the information that we gather from our simulations.\u201d<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"col-xs-12 col-md-5\">\n<div class=\"2 parsys containsResourceName resourceClass-parsys\">\n<div class=\"cqImage containsResourceName section resourceClass-image\">\n<div class=\"clearfix mw-image thumbnail add_margin_0\">\n<p><img decoding=\"async\" src=\"https:\/\/uk.mathworks.com\/company\/mathworks-stories\/storage-solutions-for-renewable-energy\/_jcr_content\/mainParsys2\/columns_copy_1259692\/2\/image_copy_copy_copy.adapt.full.medium.jpg\/1658737331839.jpg\" alt=\"A Malta prototype in background with hands holding salt in the foreground.\" width=\"439\" height=\"659\" sizes=\"auto, 100vw\" loading=\"lazy\" class=\"responsiveImage remove_border\" srcset=\"https:\/\/uk.mathworks.com\/company\/mathworks-stories\/storage-solutions-for-renewable-energy\/_jcr_content\/mainParsys2\/columns_copy_1259692\/2\/image_copy_copy_copy.adapt.150.medium.jpg\/1658737331839.jpg 150w, https:\/\/uk.mathworks.com\/company\/mathworks-stories\/storage-solutions-for-renewable-energy\/_jcr_content\/mainParsys2\/columns_copy_1259692\/2\/image_copy_copy_copy.adapt.320.medium.jpg\/1658737331839.jpg 320w, https:\/\/uk.mathworks.com\/company\/mathworks-stories\/storage-solutions-for-renewable-energy\/_jcr_content\/mainParsys2\/columns_copy_1259692\/2\/image_copy_copy_copy.adapt.480.medium.jpg\/1658737331839.jpg 480w, https:\/\/uk.mathworks.com\/company\/mathworks-stories\/storage-solutions-for-renewable-energy\/_jcr_content\/mainParsys2\/columns_copy_1259692\/2\/image_copy_copy_copy.adapt.full.medium.jpg\/1658737331839.jpg 600w\" data-aem-src=\"\/content\/dam\/mathworks\/mathworks-dot-com\/images\/responsive\/supporting\/company\/collections\/energy-storage\/energy-storage-malta-salt.jpg\" \/><\/p>\n<div class=\"caption\">\n<p>The Malta system operates as a heat pump, storing electricity as heat in molten salt.
