USA, Minnesota: Small-Scale Commercial Version of CO2/Geothermal Power Plant Could be Ready This Year

TerraCOH believes it can tap the potential of geothermal energy (StarTribune)


TerraCOH’s vision is grand. The fledgling firm would use carbon dioxide emissions — a nemesis to the planet — to power a ­geothermal energy system, which would in turn produce low-cost, clean electricity.

And TerraCOH’s patented geothermal technology could serve as a big underground battery, effectively storing renewable — but intermittent — wind and solar energy. Now, the Minneapolis-based company just needs money to turn its plans — about eight years in the making — into reality.

The good news: TerraCOH believes this year it will fire up a small-scale commercial version of its power system in North Dakota. “We are ready to build the power plant,” said Jimmy Randolph, TerraCOH’s chief technical officer. “And we’re trying to raise the money to do that,” chimed in Chief Executive John Griffin.
