PPS 250 Solid Biofuel Powerplant Project

Our Objective: We will finally make distributed renewable energy a truly practical alternative to fossil fuel energy by producing electric power and heat from biomass waste at a cost at or below fossil fuel generation, without the need for government subsidies.

A Clean, Low Cost, Alternative Fuel, Direct Combustion Powerplant:

PPS 250 Solid BioFuel Powerplant

Electric Power and Heat from Direct Combustion of Solid Biofuel

CHART.jpgHigh Efficiency Combined with Total Fuel Flexibility

·        Cost Effective, Practical, Renewable Power Generation without the Need for Government Subsidy

·        Allows Direct Combustion of  any Solid, Liquid or Gaseous Fuel

·        Eliminates the Cost and Complexity of Digesters, Gasifiers, Fermenters, Distillers, Reformers etc.

·        Ideal for Renewable Alternative fuels: Second Generation Biofuels (Algae, Bamboo, Miscanthus, Arundo, Switch Grass etc.), Bio-waste, Refuse, Prunings, Coconut Shells, Corn Husks, Shredded Paper, Wood Pellets or Scrap, etc.

·        Ideal for Distributed Power using Lignite Fuel

·        Extremely effective means for obtaining Sustainable Bioenergy Production from Marginal Lands 

·        Provides the cleanest and most efficient means possible for Direct Combustion of Carbon Neutral Solid Fuels and Cellulosic Biomass (without the need for a gasifier or digester) for Village Power, Agricultural Waste Power, and Power from all Types of Combustible Waste.

·        Can Use its own Heat to Dry Wet Solid Fuels - Simplifies fuel handling and reduces fuel cost

·        Fuel economy and global warming emissions even better than a Fuel Cell  - right now - without waiting for the “Hydrogen Economy” (see the Fuel Cell comparison page)

·        Clean exhaust meets 21st Century Environmental Requirements Without Costly Pollution Controls

·        Simple, Conventional Construction

·        Turnkey Installation using Standardized Modules to Simplify Site Preparation and Permitting
Multiple, Standard Modules Readily Lend Themselves to Creation of a Local MicroGrid

·        Totally New – Not Steam or Stirling

1.    Open Cycle that Operates on Air

2.    No “Working Fluid” to Leak

3.    Superior Efficiency, Reliability, and Maintainability

·        Much Simpler and More Efficient than Stirling Engines  (see the Stirling comparison adobe file)

·        Long engine life: Moving Parts not Exposed to Combustion Products
A vital characteristic for use of "non-traditional" renewable fuels that cause other engines to rapidly seize

·        Low cost to manufacture, high profit

·        Endorsed by 2008 “Innovation in Renewable Energy” Award by the Northern Ohio Chapter – Association of Energy Engineers

·        Competition prevented by broad patent protection (U.S. #8,858,223, (U.S. #7028476, US Patent 6,672,063, US Patent 6,390,185,  U.S. #5894729) and pending
