Geothermal Energy Turns Carbon Dioxide into Electricity (Phys.Org)
Researchers are developing a new kind of geothermal power plant that will lock away unwanted carbon dioxide (CO2) underground—and use it as a tool to boost electric power generation by at least 10 times compared to existing geothermal energy approaches.
The technology to implement this design already exists in different industries, so the researchers are optimistic that their new approach could expand the use of geothermal energy in the U.S. far beyond the handful of states that can take advantage of it now.
Tomorrow, at the American Geophysical Union Fall Meeting, the research team from Ohio State, the University of Minnesota and Lawrence Livermore National Laboratory, will debut a presentation "Multi-Fluid Geothermal Energy Systems: Using CO2 for Dispatchable Renewable Power Generation and Grid Stabilization," an expanded version of the design, along with a computer animated movie that merges advances in science with design and cognitive learning techniques to explain the role that energy technologies can have in addressing climate change.
