It is easier and safer to use and is more environmentally friendly than existing battery systems.\u201d<\/p>\n<p>Furthering the use of repurposed service stations, IFBattery\u2019s would be collected and taken to a solar farm, wind turbine installation or hydroelectric plant for recharging.\u00a0 Cushman says, \u201cIt is the full circle of energy with very little waste.\u00a0 IFBattery\u2019s components are safe enough to be stored in a family home, are stable enough to meet major production and distribution requirements and are cost-effective.\u201d<\/p>\n<p>Economically, the system would have a \u201cflow\u201d of materials at the infrastructure level.\u00a0 Cushman explains, \u201cInstead of refining petroleum, the refiners would reprocess spent electrolytes and instead of dispensing gas, the fueling stations would dispense a water and ethanol or methanol solution as fluid electrolytes to power vehicles.\u00a0 Users would be able to drop off the spent electrolytes at gas stations, which would then be sent in bulk to solar farms, wind turbine installations or hydroelectric plants for reconstitution or re-charging into the viable electrolyte and reused many times. It is believed that our technology could be nearly \u2018drop-in\u2019 ready for most of the underground piping system, rail and truck delivery system, gas stations and refineries.\u201d<\/p>\n<p>As to safety, Michael Dziekan, senior engineer for IFBattery, adds a significant set of numbers to the discussion. \u201c<a href=\"https:\/\/www.purdue.edu\/newsroom\/releases\/2017\/Q2\/instantly-rechargeable-battery-could-change-the-future-of-electric-and-hybrid-automobiles.html\">The battery does two things:<\/a> it produces electricity and it produces hydrogen. That is important because most hydrogen-powered cars run on a 5,000 or 10,000 PSI [pounds per square inch] tank, which can be dangerous.\u00a0 This system generates hydrogen as you need it, so you can safely store hydrogen at pressures of 20 or 30 PSI instead of 10,000.\u201d<\/p>\n<div id=\"attachment_13602\" style=\"width: 538px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/sustainableskies.org\/wp-content\/uploads\/2019\/02\/Purdue-nauman-battery.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-13602\" class=\"size-large wp-image-13602\" src=\"http:\/\/sustainableskies.org\/wp-content\/uploads\/2019\/02\/Purdue-nauman-battery-528x352.jpg\" alt=\"\" width=\"528\" height=\"352\" \/><\/a><p id=\"caption-attachment-13602\" class=\"wp-caption-text\">Eric Nauman, Purdue University professor in mechanical engineering and in basic medical sciences and co-founder of IFBattery, and Michael Dziekan, senior engineer for IFBattery, run tests on a membrane-free, flow battery being used to power a golf cart.

A lithium-ion battery runs on 250 watt hours per kilogram.
