Solar power is a major component in the global strategy to cut greenhouse gas emissions, but the issue is it can’t continuously produce electricity. The solution? The “hydricity” concept, which aims to create a sustainable economy by not only generating electricity with solar power but also producing and storing hydrogen from superheated water for round-the-clock power production that emits no greenhouse gasses. Scientists from Purdue University say hydricity uses solar concentrators to focus sunlight, producing high temperatures and superheating water to operate a series of electricity-generating steam turbines and reactors for splitting water into hydrogen and oxygen. The hydrogen would be stored for use overnight to superheat water and run the steam turbines, or it could be used for other applications like producing fertilizers, food or fuel. With its ability to produce electricity and other human needs without emissions, hydricity represents an exciting opportunity for the world to enter into the sustainable economy.
