Mr. Dickey has a B.S. in Architectural Engineering from Kansas State University and brings 40 years of experience in power generation development. Currently an independent consultant, Mr. Dickey spent the last ten years of his career at TAS Energy, Inc. and UTC Power, two companies that specialized in the development, sale, and installation of Organic Rankine Cycle (ORC) power equipment in the geothermal industry. Prior to these, Mr. Dickey worked for a number of well-known companies and their power engineering divisions. Specific to GreenFire’s CO2G™ development, Mr. Dickey has specific experience in the design of supercritical CO2 (SCO2) power generating systems, including Rankine Cycle power equipment, SCO2 turbines, and SCO2 expanders.
Mr. Dickey served on the Board of Directors for the Geothermal Energy Association (GEA) from 2008-2014 and has been a presenter at numerous GEA, GRC, Power-Gen, GeoPower International, and SMU Oil & Gas conferences over the last ten years. Presentation topics and specific areas of DOE-funded studies include: low temperature geothermal power generation; advanced supercritical ORC power systems; axial expanders for low-grade heat; high efficiency expanders; geothermal resource sustainability; and air-cooled combined-cycle hybrids.
Of direct relevance to the development of GreenFire’s CO2G™ technology, Mr. Dickey recently participated in a comprehensive, multi-disciplinary study funded by the Department of Energy that focused on answering key questions regarding the economic viability of CO2-based geothermal energy production (DOE Grant DE-EE0002742). As part of this study, Mr. Dickey’s team compared and analyzed SCO2 vs. water as the geothermal fluid in a 50-megawatt EGS power system; Mr. Dickey’s focus was on the surface power equipment and the functionality of the differing geothermal fluids. The key conclusions that came out of this study were as follows: SCO2 is a better geothermal fluid than water; SCO2 thermosiphon flow is a feasible concept, therefore no injection pumping is required; even after vertical production and expansion, geothermally heated SCO2 has significant pressure at ground surface to produce power; the surface power equipment is relatively straightforward and can leverage existing technology, only requiring engineering modifications; and the power system is efficient, highly scalable, and cost-effective. Mr. Dickey’s experience with this study and his knowledge of the various relevant participants is valuable for GreenFire’s effort.
