Article Summary
A promising new innovation in geothermal technology, that offers a novel solution to climate change, has been created by two researchers from the University of Minnesota's Department of Earth Sciences. The technology focuses on tapping heat from beneath the Earth's surface. By using high-pressure carbon dioxide (CO2) instead of water to extract the heat, the system has the potential to produce significantly more efficient renewable energy. At the same time, by sequestering CO2 deep underground, it actively reduces atmospheric CO2. It's being hailed as a two in one solution for climate change.
