Cogeneration of Both Heat and Electricity

Cogeneration: Tomorrow's Building Complex BECCS, MicroGrids, Wind, Solar and Nuclear

The focus of this chapter will be the world's 1 million or so industrial fires, mostly large facilities with small power houses or large boiler rooms in their basements.  Schools, hospitals, large office buildings, shopping malls, factories, military bases, the U.S. Capitol Building Complex, etc. 
The variety is seemingly endless.  In some countries such facilities contribute over 20% Climate Change.

Often too large to be powered by their electrical grids, they produce some or all of the energy they consume.  Your author worked for 28 years in such an energy environment.

Urenco has called for European development of very small 5 to 10 MWe 'plug and play' inherently-safe reactors based on graphite-moderated HTR concepts. It is seeking government support for a prototype "U-Battery" which would run for 5-10 years before requiring refueling or servicing.

Already operating in a remote corner of Siberia are four small units at the Bilibino co-generation plant. These four 62 mWt (thermal) units are an unusual graphite-moderated boiling water design with water/steam channels through the moderator. They produce steam for district heating and 11 MWe (net) electricity each. They have performed well since 1976, much more cheaply than fossil fuel alternatives in the Arctic region. - World Nuclear Association.



We're talking about those small power plants used for universities, offices, factories, hospitals, airports, military bases, shopping centers, etc.
More about cogenerators from the Center for Climate and Energy Solutions:
Cogenerators at 3,000 U.S. building complex sites (a total of about 14,000 industrial boilers) make about 10% of ALL U.S. electricity and a similar proportion of U.S. heat. 3/4 are gas.
Large cogeneration systems (100 megawatts or more in capacity) account for roughly 65 percent of total U.S. cogeneration capacity.
This idea is important because the U.S. Billion-ton Biofuel Program promises to replace coal at smaller cogeneration sites: 
A recent study showed using
fossil fuel processed biofuels such as corn actually produced a net increase in Climate Changing CO2.  Biofuels Increase CO2.pdf 
Cellulosic biofuels, a cheaper and much more abundant feedstock, produced by using advanced nuclear reactors to end biofuel's CO2 emissions, are central to this site's concept.
