The Midcontinent Rift Zone in North America could become a massive natural hydrogen production source, supporting the global demand for clean energy.About 1.1 billion years ago, the North American continent nearly split in two, leaving behind a 1,900-kilometer-long volcanic rock formation known as the Midcontinent Rift Zone. Researchers from the University of Nebraska–Lincoln are studying this rift—which stretches from beneath Lake Superior through parts of Minnesota, Michigan, Wisconsin, Iowa, Nebraska, and Kansas—to determine how best to access the vast amounts of hydrogen it harbors, SciTechDaily reported on November 15.
