World Energy Technology Series 3 – COMBINED HEAT AND POWER (COGENERATION, TRIGENERATION)

Your energy technology and pricing expert is releasing issue #2 on Advanced Coal Technologies.  This series will focus on energy technologies (fossil, renewable, nuclear, storage) by giving information on the energy resource, basic principles, energy conversion technology, overnight capital cost ($/kW), operating and maintenace costs (fixed O&M $/kW/yr, variable O&M $/kWh), maintenance and overhaul schedule (to determine capacity factor and availability), outage rate and reliability, construction lead time, economic life, conversion efficiency (input energy to output power or heat or cooling), fuel heating value (gross and net BTU/lb, kJ/kg, BTU/scf, kJ/Nm3, BTU/gal, kJ/liter), fuel costs ($/MT, $/kg, $/bbl, $/liter, $/MMBTU, $/GJ) in order to arrive at its levelized price and levelized generation cost of energy. The benefits and risks of each technology is also presented. I encourage the reader to follow this series.

A complete power point presentation may also be obtained from this link to complement this article. More »

Combined Heat & Power (Cogeneration)

Combined Heat and Power (CHP) is the simultaneous generation of electricity and steam (or heat) in a single power plant. It has been long used by industries and municipalities that need process steam or heat as well as electricity. CHP or cogeneration is not usually used by large utilities which tend to produce electricity only. It is advisable only for industries and municipalities if they can produce electricity cheaper or more conveniently; otherwise, buy from the utility instead.

In theory, CHP provides the most efficient use of energy resources, often utilizing up to 90% of the heat energy of the fossil fuel. In practice, while the efficiency of entire process is recognized, its application has been limited.
