Why Geothermal is Both Hot and Cool | Renewable Energy Podcast

Nevada, United States [RenewableEnergyWorld.com] Most geothermal development in the near future will come from conventional, medium-temperature hydrothermal power plants. But beyond the next few years, a large number of projects that utilize temperature extremes, both hot and cool, may come online. In this podcast, we'll look at two pioneer companies developing innovative, unconventional geothermal projects.

Michael Hayter, Director of Geothermal Development for Raser Technologies, discusses the company's achievements and setbacks over the last two years as it develops a 10-MW plant in Utah that utilizes low-temperature brine for electricity. If successful, Raser may open the door for more “build as you go” geothermal power plants.

Jared Potter, President and CEO of Potter Drilling, talks about the year of testing for the company's new “hydrothermal spallation” drill, which could lower drilling costs by a factor of ten. This year, the heat was on, as the company had to achieve certain milestones in order to get more funding from Google. If Potter can achieve what its goals, the company may hold the key to the cost-effective development of high-temperature Enhanced Geothermal Systems.
