Is Advanced Clean Coal the Answer to our Global Power Problem?
Is Advanced Clean Coal Technology the Answer to our Global Power Problem?
Remaining Life of Fossil Fuels (oil, natural gas, coal)
Recent events have thrust lately renewed interest in “advanced clean coal” technologies to provide additional power generation capacity in view of dwindling and expensive oil supplies (remaining life 39 years), natural gas (61 years). World wide coal reserves are expected to last over 231 years (remaining life = reserves / extraction rate).
However, due to concerns arising from pollution (emission of sulfur as SO2, toxic ash and heavy metals) and climate change (emission of CO2 greenhouse gases), the utilization of coal for power generation has spurred researches leading to the development and commercialization of so called “advanced clean coal” technologies.

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.
