It is possible, at least in theory. Some researchers, currently engaged in a project funded by the Brtitish government through the UK Research and Innovation program, are convinced of this. Ok, it&#8217;s just a suggestion so far. But in the future, perhaps, the idea could materialize. The hypothesis, after all, is pretty simple. If it&#8217;s true that all <strong>batteries<\/strong> use a chemical process to transfer energy, scientists ask, why shouldn&#8217;t it be possible to use the reactions that take place continuously in the ground?

In this case it takes place underground where microorganisms use the energy to reduce carbon dioxide and produce a more complex molecule: <strong>acetate<\/strong>.<\/p><\/blockquote>\n<p>The substance, in effect, works as a chemical energy store. &#8220;When needed, another circuit (known as a <strong>microbial fuel cell<\/strong>) is switched on, which activates a different set of bacteria to break down the acetate,&#8221; Euronews writes. &#8220;These feasting bugs release electrons which flow through the circuit, providing electricity on demand.&#8221;<\/p>\n<div class='avia-iframe-wrap'>\n<blockquote class=\"wp-embedded-content\" data-secret=\"uDFrXQuAGa\"><p><a href=\"https:\/\/resoilfoundation.org\/en\/articles\/microbes-soil-desorption\/\">Microbes are resurging in decontaminated soils thanks to desorption<\/a><\/p><\/blockquote>\n<p><iframe loading=\"lazy\" class=\"wp-embedded-content\" sandbox=\"allow-scripts\" security=\"restricted\" style=\"position: absolute; clip: rect(1px, 1px, 1px, 1px);\" title=\"&#8220;Microbes are resurging in decontaminated soils thanks to desorption&#8221; &#8212; Re Soil Foundation\" src=\"https:\/\/resoilfoundation.org\/en\/articles\/microbes-soil-desorption\/embed\/#?secret=xpLxuyFsvI#?secret=uDFrXQuAGa\" data-secret=\"uDFrXQuAGa\" width=\"600\" height=\"338\" frameborder=\"0\" marginwidth=\"0\" marginheight=\"0\" scrolling=\"no\"><\/iframe><\/div>\n<h5>A revolution in energy storage?<\/h5>\n<p>Current storage technologies, researchers <a href=\"https:\/\/gow.epsrc.ukri.org\/NGBOViewGrant.aspx?GrantRef=EP\/X018865\/1\" target=\"_blank\" rel=\"noopener\">explain<\/a>, face many issues including resource availability, cost and <strong>environmental impact<\/strong>.
