Testing High-Temperature Geothermal Energy Technology in the Lab and in the Field
Geothermal energy currently provides just a fraction of the United States' electricity, but it has the potential to power more than 100 million American homes. Effectively tapping into this resource and generating electricity from it at a lower cost will require developing technology that can efficiently operate at very high temperatures.
FastCAP Systems has developed innovative technical solutions within the geothermal industry to operate at extremely high temperatures encountered in wells and around vents. The operating temperature limit of FastCAP's system has been pushed as high as 480°F and in some cases up to 570°F. In order to advance the system's technological readiness level, this project will follow a programmed plan of tests through Sandia National Laboratories as well as an integrative field demonstration.
PROJECT INNOVATION + ADVANTAGES
FastCAP Systems holds multiple world records across several performance metrics for its nanotech-based capacitor designs, including achieving the highest power density, highest energy density and highest recorded operating temperature for these devices. Compared to today's commercially dominant technologies, those records represent a 1,000 percent increase in power density and up to a 600 percent increase in energy density.
FastCAP has already tested some of these technologies at Sandia, including when the company's capacitor broke the record for operating at the highest temperature ever for a rechargeable energy storage device.
Building and operating geothermal power plants creates domestic jobs and provides communities with local sources of electricity.
Geothermal energy is virtually emission-free since it taps into existing sources of heat energy already trapped beneath the Earth's surface. Increasing access to geothermal energy can help reduce greenhouse gas emissions and other pollutants from fossil energy sources.
Geothermal energy can function as an entirely domestic, base-load source of energy, increasing the United States' energy independence and providing grid operators with a constant source of clean electricity.
