Employment
2013 – Present- Consultant for gas insulated equipment for Mitsubishi Electric Power Projects
1990-2013 Mitsubishi Electric Power Products, Inc - Vice President Power Systems Group
1988-1990 ABB CGIT bus (GIL)
1974-1988 Westinghouse Electric Corporation CGIT bus, IPB, GIS (joint venture with Mitsubishi Electric)
1970-1974 High Voltage Power Corporation Project Engineer for development, manufacture and installation of CGIT bus
1968-1970 Ion Physics Corporation Engineer for research of high voltage vacuum breakdown
1966-1968 MIT High Voltage Research Lab. Research Assistant for vacuum and compressed gas high voltage insulation
1964, 1965 Florida Power Corporation Summer intern in Systems Engineering Dept—standards and load flow studies.
Basic research in high voltage insulation and later sponsored research in industry and publication of technical papers provided opportunity to contribute to scientific understanding of high voltage vacuum insulation, the effect and control of conducting particles in gas insulation and the performance of cast epoxy insulators for high voltage electrical stress. This was applied to the development, manufacture and installation of high voltage compressed gas insulated transmission lines for installations in the USA, Canada, Australia and Sweden. Design engineer and project manager for the world’s first direct buried 230 kV SF6 gas insulated line (GIL) in New Jersey in 1972 for PSEG—this GIL is still in service. Led EPRI and DOE sponsored development of 1100 kV gas insulated lines. Hold 17 patents in the field of gas insulated equipment. Presently involved in the transition from SF6 insulated high voltage equipment to vacuum interrupters and alternative gases. |

| Dr. Hopkins has over 20 years of academic and industrial experience focused on high-frequency, high density power electronics with emphasis on packaging and pulsed power. His expertise is in combined electro-thermal high density power electronics design. Recent projects are ultra-fast solid state circuit breakers, advanced PV converter system incorporating 1200V bi-directional FETS, and 24kV/100A supercascode power electronic switches extendable to >100kV. He is a professor in Electrical and Computer Engineering, and Director of the Laboratory for Packaging Research in Electronic Energy Systems (PREES), which is part of the NSF FREEDM (Future Renewable Electrical Energy and Delivery Management) Systems Center at North Carolina State University -- The NSF Center for Smart Grid Research. He received his Ph.D. in Electrical Engineering from Virginia Tech, and spent his early career at the R&D centers of GE and Carrier Air-Conditioning Companies in advanced power electronics systems for military and commercial applications. He has published over 150 journal and conference articles, a number recognized with awards and is an IMAPS Fellow. |

| Concorde has developed a chemical purification process that cleans used SF6 at hundreds of pounds per hour, while significantly decreasing energy consumption, consumable materials, and greenhouse gas pollution. This groundbreaking design uses a one of a kind refrigeration technique that exploits known thermodynamic properties of fluids in order to achieve cryogenic temperatures. This level of refrigeration is achieved using no consumables whatsoever. The recycling tower removes impurities from the SF6 by utilizing unique mass transfer correlations that were researched and explored in great detail by Concorde’s engineers and refrigeration experts. Two separate moisture removal techniques are incorporated into the design to ensure that no moisture is recovered in the product stream.
Ingenuity in electrical design allowed this degree of purification to be achieved while decreasing overall power consumption. This additional feat further minimizes global pollution, and energy consumption, by requiring less power draw overall to our facility.
Zero greenhouse gas pollution is made possible by the recycle tower’s closed system design, which also means no product, or reactants are lost to the environment.
Concorde’s business model is an epitome of customer service prioritization. SF6 is retrieved from customer equipment, purified, and returned to Concorde’s customers. Concorde’s large scale purification design decreases purification time and ensures that product is always available. The decreased necessity for labor hours towards processing gas allows us to spend more time in the field servicing our customers and focusing on customer service. Concorde processes tens of thousands of pounds of SF6 weekly, and spends numerous hours out in the field making sure our customers are always up and running. Purification on sight can take hours depending on the volume of gas that needs to be processed. Concorde takes the dirty gas and replaces it right away with an already purified product that has been certified in advance by our SF6 specialized laboratory. |
