The Midcontinent Rift is an ancient tectonic formation stretching from Lake Superior through parts of Minnesota, Wisconsin, Michigan, Iowa, Nebraska, and Kansas. This volcanic rift was created around 1.1 billion years ago when tectonic activity almost split the North American continent. Today, the rift lies between 3,000 and 5,000 feet below ground, making it deep enough for storage but still within reach for potential extraction.
A Hydrogen Treasure Waiting to Be Discovered
Hydrogen’s role as a clean energy alternative is becoming more critical as countries transition away from fossil fuels to combat climate change. Unlike fossil fuels, natural hydrogen regenerates continuously when water reacts with volcanic rock, making it a renewable and sustainable energy source.
Professor Seunghee Kim, one of the lead researchers, explains, “Our understanding of the processes behind the formation, migration, and accumulation of natural hydrogen in the deep subsurface is still evolving.”
In 2019, the team drilled a well to explore hydrogen production in the rift. Their initial findings indicate promising signs of hydrogen accumulation, strengthening the case for future extraction.
Funding Clean Energy Innovation
The University of Nebraska–Lincoln has secured a $1 million grant from the National Science Foundation's RAISE (Research Advanced by Interdisciplinary Science and Engineering) initiative. Over the next five years, this funding will support the study of subsurface hydrogen flows, geological storage, and microbial interactions that may influence hydrogen reserves.
The Global Implications of Rift-Based Hydrogen
The Midcontinent Rift’s potential hydrogen reserves are part of a much larger trend, as scientists explore other geological rifts worldwide. Countries such as France, Germany, Russia, and regions in Africa are also investigating their rift zones for hydrogen resources. These efforts align with global ambitions to achieve carbon neutrality by developing scalable, clean energy solutions.
Hydrogen: A Vital Energy Transition Tool
Hydrogen is increasingly viewed as a key component of the global energy transition, given its ability to reduce carbon emissions significantly. It can fuel industries, power vehicles, and generate electricity without releasing harmful pollutants. As demand for hydrogen grows, natural reserves such as those found in the Midcontinent Rift could play a crucial role in meeting future energy needs.
Professor Karrie Weber, another principal investigator, emphasizes the importance of the geology: “The rift's location provides a unique opportunity—it is deep enough to store hydrogen safely, yet accessible enough for extraction.”
Unlocking Earth’s Natural Hydrogen Potential
According to the U.S. Geological Survey, Earth's crust holds tens of millions to billions of megatons of hydrogen, capable of supporting global energy demand for thousands of years. However, extracting hydrogen from such depths presents significant challenges, underscoring the importance of rift sites like the Midcontinent Rift as ideal sources for clean hydrogen.
This groundbreaking research offers hope for a new era of energy independence—one that leverages the Earth’s natural resources while helping countries transition to cleaner, more sustainable energy systems.
