Sage Geosystems (SAGE) and Metamaterial Inc. (META) announced that META has collaborated with SAGE to submit a $10,000,000 initial proposal under an open call for the Advanced Research Projects Agency - Energy (ARPA-E) U.S. Department of Energy. If successful, the project (codenamed "Pluton") will run over a three-year period. The proposal will validate aspects of META's NANOWEB® proprietary production methodology to develop a novel Thermo-Electric Generator (TEG) system. SAGE has teamed up with META to model, co-develop, investigate, and validate a new TEG technology for harnessing of geothermal energy in drilling wellbores at selected testing locations. There is significant interest in accessing geothermal energy from the Earth as it provides an infinite clean and renewable baseload source of energy. Most geothermal operations harvest heat using water, bring the heated water to the surface and produce electricity with an Organic Rankine Cycle (ORC) turbine and generator. A high upfront capital cost means the energy generated may not be cost-competitive with solar or wind. Project Pluton aims to construct a geothermal well (new or existing well) in which will strategically place thermoelectric generators (TEGs) to generate subsurface electricity from the temperature differences that inherently exist in a geothermal well as heat is harvested. The new TEG solution utilizes the Seebeck effect to generate electricity. META designs and manufactures advanced materials and performance functional films which are engineered at the nanoscale to control light and other forms of energy. NANOWEB® is a revolutionary transparent conductive film made of an invisible (sub-micron) metal mesh that can be fabricated onto any soft or rigid surface. SAGE combines innovative approaches to heat harvesting with modern oilfield expertise and methodologies to enable geothermal energy anywhere in the world - terawatts of clean, secure and baseload energy by 2050.
