Hiroshi Morihara, Ph.D., President and CEO
Hiroshi has experience developing a new innovative polysilicon technology from R&D through pilot plant to full commercial production. In 1977 Hiroshi and Bill Breneman were intimately involved in technical and managerial leadership roles in the Low Cost Silicon Solar Array Project funded by the U.S. Department of Energy.
Hiroshi was also instrumental in facilitating the integration technology purchased by Union Carbide from Komatsu Electronic Materials for the pyrolysis of silane into polysilicon rods, the favored shape factor for the electronic industry and solar industries. This technology was demonstrated in the semi-commercial scale facility and later up-scaled to a $250 million, 1200 ton/year facility which began operation in Moses Lake WA in 1985.
Today, the original Moses Lake facility continues to produce high quality materials for use in both electronic and photovoltaic applications. While ownership of the enterprise has changed hands over the past thirty years, the basic process remains fundamentally unchanged as the leading technology for low cost and high quality.
Bill Breneman, P.E., Process Engineering Manager
Bill, together with Hiroshi, has experience developing a new innovative polysilicon technology from R&D through pilot plant to full commercial production. In 1977 Morihara and Breneman were intimately involved in technical and managerial leadership roles in the Low Cost Solar Array Project funded by the U. S. Department of Energy. The goal of the overall program was to demonstrate the feasibility and practicality of production of terrestrial photovoltaic systems based on silicon. While working for Union Carbide Corp. under a DOE/JPL contract, Bill was responsible as Principal Investigator for developing a process for large scale production of silane with a quality suitable for the production of “solar grade” silicon. Bill also developed analytical methods for monitoring the quality of the silane and polysilicon. As the program moved through the various stages of development, Bill became the lead design engineer for a world scale facility designed to produce silane and polycrystalline silicon. Bill currently provides technology consulting services to the successor company, REC Silicon.
David Carter, B.S., Project Manager
As the project manager, David first expanded the pilot plant facility, then worked to provide as well as the design and construction of our first commercial plant. His primary role is to coordinate and manage the various parties involved including technology providers, design engineering firms, and equipment suppliers. In addition, David has extensive process engineering knowledge that is applied to develop and improve HM3 Energy’s technology. David has much experience in taking projects from start-up status to finished commercial plant.
Howard Dawson, Ph.D., Analytical and QA Manager
Howard contributed to the success of the polysilicon project (see Hiroshi Morihara bio) as Quality Assurance manager to make the product attractive not only to the solar cell industry but also to the semiconductor industry. Prior to polysilicon work, Howard Dawson worked many years in the pulp and paper industries acquiring a deep understanding of wood chemistry.
Andrew Green, B.S., Project Manager
Andrew has over 25 years of experience in semiconductor and solar wafer processing—from innovative process equipment design to start-up and trouble shooting of various pieces of process equipment and managerial work. He was responsible for coming up with the concept for, and designing of, our proprietary Pressure Steam Pulping (PSP) system used in wood chip pretreatment, as well as our first and second generation torrefiers.
