The CHP Shibboleth

(This is the last article to be published during the trip to Australia.) Combined Heat and Power (CHP) is dragged out periodically by supporters of the AGW CO2 global warming hypothesis, to promote distributed power and the use of wind Continue reading The CHP Shibboleth

Role of Combined Heat Power

Environmental organizations repeatedly attempt to deride the efficiency of existing power plants and promote the use of combined heat and power (CHP). Some radical environmental organizations, such as Greenpeace, claim that CHP has en efficiency of over 90%. Greenpeace makes Continue reading Role of Combined Heat Power

CHP Creates More Energy Confusion

Combined Heat and Power (CHP) is mentioned in the EPA’s proposal to cut CO2 emissions 30%, as a possible approach for achieving improved energy efficiency. But how does CHP improve energy efficiency, and if so by how much. Some radical Continue reading CHP Creates More Energy Confusion

CHP: Progress or Regression?

A major misconception about Combined Heat and Power (CHP) is that people believe its efficiency is far greater than other methods for generating electricity. Efficiencies of over 90% are claimed for CHP, but these are misleading. CHP uses the exhaust Continue reading CHP: Progress or Regression?

Bogus High Efficiency of Combined Heat and Power Plants

People still ask whether combined heat and power (CHP) achieves efficiencies in the 80% and 90% range, which compares with 32% for traditional coal-fired plants, 45% for a gas turbine, and 60% for a natural gas combined cycle (NGCC) power Continue reading Bogus High Efficiency of Combined Heat and Power Plants
