Renewable Combined Heat & Power Solution
Features:
ZeroPoint's standardized CHP Solution is designed to produce enough synthesis gas to generate approximately 1.8 MW of electricity and 8.4 MMBtu/hr of recoverable heat for thermal applications. The ZeroPoint CHP approach allows power and heat to be produced with significantly higher conversion efficiencies than direct combustion of biomass. The ZeroPoint CHP Solution is delivered in a modular, skid-mounted package featuring a high efficiency downdraft gasifier with on-board gas scrubbing equipment. The process utilizes state of the art PLC controls to maximize process stability and conversion efficiency. ZeroPoint's CHP Solution is designed to process a wide variety of biomass fuels including wood chips, wood pellets, palm fruit wastes, sugar cane bagasse, dried distillers grain, corn stover, switchgrass, agricultural and forestry wastes and other locally available feedstocks.

The figure at lower right shows a simplified flow diagram. Biomass enters the gasifier for conversion into synthesis gas. The gas is cooled and cleaned to remove particulates, tars and oils. The conditioned gas is sent to a reciprocating engine to produce electricity. Engine water jackets and exhaust heat recovery systems capture thermal resources for on-site use.

Market Opportunities
Waste Water Treatment Plants
offer a unique opportunity for biomass to energy solutions to utilize sludge as fuel to reduce disposal and feedstock costs. Baseload heat and power can be provided to reduce costs and/or generate revenue. Flared methane can be captured and gas scrubbing costs are lower for economic benefit.
Landfill Gas to Energy Projects
with declining gas production curves possess pre-existing infrastructure including; land, buildings, reciprocating engines, grid connections and power purchase agreements. The life and value of these assets are extended and increased with the ZeroPoint solution. Waste wood streams further enhance project economics at many sites seeking alternative uses for this material.
Remote Power Generation
currently occurs with high cost diesel fuel. The ZeroPoint solution offers an attractive replacement or co-fueling opportunity. This solution is economic without subsidies.
