Combined heat and power systems can range in terms of size (10 kilowatts up several megawatts or more), number of generators, and application, making them suitable for a wide variety of power and heating purposes. Given this versatility, properly installing a CHP system requires experience in mechanical and electrical system engineering and project management. This …

Cogeneration is not new. Large industrial facilities have burned natural gas to generate electricity and have recovered the heat from the engine jacket and exhaust to serve as process and space heat without burning additional fuel. In fact if you examine the large gap between natural gas costs versus electrical prices…

Composting Strategies

Originally posted on BioEnergy Consult Blog:
The methodology of composting can be categorized into three major segments—anaerobic composting, aerobic composting, and vermicomposting. In anaerobic composting, the organic matter is decomposed in the absence of air. Organic matter may be collected in pits and covered with a thick layer of soil and left undisturbed six to…

Biogas Upgradation

Originally posted on BioEnergy Consult Blog:
Enrichment of biogas is primarily achieved by carbon dioxide removal which then enhances the energy value of the gas to give longer, driving distances with a fixed gas storage volume. Removal of carbon dioxide also provides a consistent gas quality with respect to energy value. The latter is regarded to…

Palm Oil Mill Effluent

Originally posted on BioEnergy Consult Blog:
Image via Wikipedia Palm Oil processing gives rise to highly polluting waste-water, known as Palm Oil Mill Effluent (POME), which is often discarded in disposal ponds, resulting in the leaching of contaminants that pollute the groundwater and soil, and in the release of methane gas into the atmosphere. POME…

Ethanol from lignocellulosic biomass is produced mainly via biochemical routes. The three major steps involved are pretreatment, enzymatic hydrolysis, and fermentation as shown in Figure. Biomass is pretreated to improve the accessibility of enzymes. After pretreatment, biomass undergoes enzymatic hydrolysis for conversion of polysaccharides into monomer sugars, such as…
