January 6, 2004 - Thousand Oaks CA – Proe Power Systems, an advanced engine research and development company, announced that the U.S. Patent and Trademark Office today issued U.S. Patent Number 6,672,063 for it’s HRPG™ heat recovery power generator technology.   Proe Power Systems’ founder and President, Richard Proeschel, claims: “The revolutionary HRPG™ technology has the potential to fundamentally change the dynamics of the distributed power generation market by meeting the U.S. Department of Energy (DOE) cogeneration requirements without the need for steam boilers or water heaters”. 


Cogeneration is the recovery of the otherwise wasted heat in an engine’s exhaust to generate additional power and/or to extract useful heat for warming buildings or for other heating processes.  Cogeneration is a critical technology for reducing fossil fuel consumption and to thus simultaneously improve the environment while cutting back America’s dependence on foreign oil.  The DOE offers incentives to meet its cogeneration requirements.


To date, the DOE cogeneration requirements have been met by using engine exhaust heat to generate steam (to drive a steam engine for additional power) and/or to heat water.   This “wet” approach has forced cogeneration vendors to target a small set of prospects.  Steam boilers involve extensive, expensive, safety requirements.   Hot water heating is limited to those that have a significant need for thermal energy as part of their operations or those that are able to use hot water heat in existing or newly designed heating systems.


In contrast to the complex “wet” cogeneration approach, Proe Power Systems’ new “dry” HRPG™ technology provides a simple “bolt-on” cogeneration solution that simply uses air instead of water or steam.  An existing internal combustion powerplant can be easily modified by connecting the internal combustion engine exhaust into a the HRPG™ heat exchanger and then coupling the drive shafts of the HRPG™ engine and the existing internal combustion engine.   The linked engines require no additional controls and the internal combustion exhaust heat then drives the HRPG™ engine to produce 15% to 25% additional electrical power from the same amount of fuel.   In addition to the power increase, the Proe HRPG™ engine exhaust is clean hot air having the potential for an additional efficiency gain (exceeding 20%) by simply exhausting it into a building directly or through the building’s existing hot air ducts.


Proeschel emphasized the importance of the newly issued patent: “The addition of the HRPG™ technology to our already impressive patent portfolio now makes Proe Power Systems the leader in applying thermodynamic science to meeting President Bush’s goals of promoting energy independence for our country while dramatically improving the environment.  Although our technology is extremely simple and practical, it has the potential to radically change the power generation market - right now - without waiting for the hydrogen economy.”
