Imagine for a minute that all the energy we need or could ever need was at our fingertips, stored in the most common element on Earth that you can obtain at no cost. Consider that this energy can be captured and used to power many sectors of our economy and multiple areas of human activity. And imagine if it could rid us forever of the fossil fuels that do so much damage to our climate. Although it may seem like a science fiction story that has not yet come to life, it is an exciting dream that will be a panacea for our environmental problems. However, such a utopian scenario is not that far from reality. Say hello to hydrogen energy.
