Solving the world&#x27;s trillion-dollar energy storage crisis. (multi-trillion, actually.)
<a href="https:&#x2F;&#x2F;www.terramenthq.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.terramenthq.com&#x2F;</a><p>About a year ago, I started spending more time researching about climate change. I learned how important energy storage will be to enable renewable energy to displace fossil fuels. The more I read, the more fascinated I became with the idea of building underground pumped hydro energy storage. I found a research paper from the U.S. DOE written in 1984 showing that the idea was perfectly feasible and affordable, but it seems that nearly everyone has forgotten about it since. (they didn&#x27;t build it at the time because the demand wasn&#x27;t there yet. Now energy storage demand is growing exponentially)<p>A year later, I&#x27;m applying for grant funding to get it built. I know that nearly everyone will tell me I can&#x27;t do it because this or that reason. Because people don&#x27;t like change and they&#x27;re scared of big things even if the research shows it makes perfect sense. But I&#x27;m doing it anyways because no one else is getting it done. The idea is too compelling and too important to ignore. So here goes nothing!
