Biography

Mr. Herbst joined The Center for Electromechanics in 1985.  He is currently Co-Principal Investigator and Program Manager for the Electric Ship Research and Development Consortium (ESRDC) program at the Center for Electromechanics.  The ESRDC has been funded by the Office of Naval Research since 2002 to develop advanced design tools and technologies for integrated electric power systems for future Naval vessels.  He also serves as the technical lead for related research activities funded by the Naval Surface Warfare Center- Carderock Division.

Prior to his current assignment, he served as the Principal Investigator and Program Manager for the Advanced Locomotive Propulsion System (ALPS) project, a $30M effort to develop and demonstrate an advanced hybrid electric propulsion system for high speed passenger locomotives. The ALPS system used a 5000 hp gas turbine prime mover directly coupled to a high speed generator and a 480 MJ flywheel energy storage system to provide additional power to the locomotive traction system.

Mr. Herbst previously was the Project Engineer for the 9 MJ Range Gun System, a $26M program to develop a field portable high energy electromagnetic launcher, including the 5000 hp gas turbine prime mover, pulsed power supply generator, 90 mm bore railgun, and all required auxiliary systems. This project included successful testing of the lightweight electromagnetic launcher at the U.S. Army electric gun test facility at Picatinny Arsenal.

Prior to joining UT-CEM, Mr. Herbst was a project engineer for Stewart and Stevenson Services of Houston, Texas, in their oil field and gas turbine divisions, where he was involved in the design and fabrication of mobile oil field equipment and large gas turbine generator sets.

Current Projects

* Electric Ship Research and Development Consortium – this program involves modeling and simulation of advanced naval power system architectures, development of advanced early stage ship design tools, power system integration studies and component/technology development activities.

* Naval Energy Security – this program involves the development of a simulation tool for the evaluation of techniques and technologies to ensure energy security for land-based military installations.  The tool enables the evaluation of the integration of renewable energy resources  and energy storage to address evolving needs for power management in the event of long term disruption of conventional electric utility supply.
