TerraCOH, Inc. Semi-Finalist for NRG COSIA Carbon XPRIZE

October 17, 2016

Minneapolis, MN: Today, TerraCOH, Inc., whose mission is to produce zero-carbon, low-cost electrical power using TerraCOH’s proprietary Carbon Dioxide (CO2) Plume Geothermal – CPGTM technology, announces they are moving forward into the semi- final round of the NRG COSIA Carbon XPRIZE ( The NRG COSIA Carbon XPRIZE mission is to challenge the world to reimagine what can be done with CO2 emissions by incentivizing and accelerating the development of technologies that convert CO2 into valuable products. XPRIZE will provide contacts, relationships and funds to help these companies meet their mission with the finalist competing to receive financial awards of up to $7.5 million.

TerraCOH CEO John Griffin said, “Reaching the semi-final stage of the XPRIZE challenge is another indication that our proprietary Carbon Dioxide (CO2) Plume Geothermal – CPGTM technology has the ability to dramatically change today’s approach to power generation by eliminating carbon emissions, while simultaneously utilizing CO2 as a working fluid both in power systems and below ground. This step in TerraCOH’s development is a testament to our committed employees along with the University of Minnesota, where our technology was originally developed, and on-going work continues with our academic/research partners; Lawrence Livermore National Lab, The Ohio State University, and ETH Zurich

About TerraCOH Inc.: TerraCOH Inc. is a renewable energy company based in Minneapolis, MN. Founded in 2014, TerraCOH is in the process of implementing their technology to generate zero-carbon, baseload (24/7) electricity.

GEG Group submits application to MacArthur Foundation’s 100-Million-$-and-Change Competition

October 3, 2016

Today, the GEG Group at ETH-Zürich and team members SwissGeoPower, TerraCOHHerrenknecht, Basler&Hofmann, Sintef, and Farner as well as the LTR Group at ETH-Zürich submitted their application to the 100-Million-$-and-Change Competition. According to the MacArthur Foundation, this is “A competition for a $100 million grant to fund a single proposal that promises real and measurable progress in solving a critical problem of our time.” The following is the executive summary of our application:

A global PROBLEM is humanity’s suffering from climate change and nuclear risk. Our SOLUTION is to enable worldwide access to Earth’s internal heat at depths of 5-10 km, resulting in an inexhaustible resource of clean, renewable geothermal energy, available anywhere, anytime, for anyone. Thus, we propose to realize small-scale, distributed, geothermal electricity/heat power plants, providing ample, clean 24/7-electricity/heat with power generation costs lower than those for coal, oil, and natural gas. However, the current high costs of drilling 5-10 km deep, prevent economic use of this energy resource. Thus, the focus of our proposal is the development of a revolutionary, i.e., much-lower-cost, ultra-deep (10 km) drilling technology. The RESULT of our “100&Change”-Project is affordable, clean 24/7-electricity/heat worldwide, reducing global climate change and nuclear risk.

Record student numbers in Geothermal Energy Course

September 30, 2016

The Geothermal Energy course, offered by the GEG Group, within the Earth Science Masters Program this year has 37 registered students drawn from a diverse range of disciplines. The increase in the number of participants continues a trend established over the past few years, and reflects the increasing interest in geothermal studies amongst the students.


Visit of Werner Siemens Foundation at the Deep Underground Geothermal Lab (DUG Lab) at the Grimsel rock laboratory

August 30, 2016

geophysicsPresentation given by Dr. Florian Amman

On August 23, 2016, ETH-Zürich Prof. Martin Saar (Chair of the Geothermal Energy and Geofluids Group), ETH-Zürich Prof. Domenico Giardini (Chair of the Swiss Competence Center for Energy Research – Supply of Electricity – SCCER-SoE), and the ETH-Zürich Foundation invited the Werner Siemens Stiftung/Foundationand friends of ETH Zürich to an excursion to  the Deep Underground Geothermal Laboratory (DUG Lab) at the NAGRA Felslabor (rock laboratory) at the Grimsel Pass.

We are very happy about the feedback we received about that day. For example, one participant wrote afterwards: “ für den gestrigen Ausflug bedanke ich mich ganz herzlich. Prima ausgesucht – perfekt organisiert – rundum an alle Details gedacht – spannend. So sieht es wohl aus, wenn Leute mit Spass an der Arbeit wirken – keep going!”
