Micro Combined Heat and Power Market Trends and Foerecast to 2016.

A Micro CHP system is nothing but the small power plant which provides all the power for an individual building; in terms of ventilation, air conditioning, mechanical  energy, electric power, and heating. It is a small version of combined heat and power which have been used with large scale electric power plants. Based on end -user, CHP is classified into following categories as: 
  1. Industrial CHP
  2. CHP with district heating
  3. Combined cooling
  4. Heating and Power
  5. Mini CHP and
  6. Micro CHP
The Purpose behind using Micro CHP system is to utilize more of the energy in the fuel. As the stem power plants which generates the electric power needed for modern life by burning fuel , are not very efficient due to this reasons the Micro CHP systems are used widely. As per the Carnot's  theorem, a heat engine cannot be 100% efficient; it cannot convert anywhere near all the all the heat in the fuel it burns into useful forms such as electricity. So heat engines always produces a surplus of low temperature waste heat known as "secondary heat" or "low grade heat". In Modern plants at most 40-67% of the energy is exhausted as waste heat, in past this energy was usually wasted to the environment. Due to Micro CHP system which were built in recent years in cold climate countries, utilize the waste heat produce by large power plants for heating.

In many cases Industrial CHP systems primarily generate electricity and heat is a by product where as in Micro CHP systems in homes or small commercial buildings are controlled by heat demands and electricity is a by product. To date,  Micro CHP systems are much popular as expected and thus more customers are attracted towards it. This system is efficient because the energy used is distributed and continuosly used over the electrical grid.

Micro CHP is mainly a substitute for traditional boiler which are used as heating systems in recidencial and small commercial buildings. As micro CHP units generate elecricity on the basis of KW power outputs these units acn be used in standalone or multi family homes, nursing homes, shops and restaurants. Thease units are Best suited for buildings that have ideal "heat sinks" such as swimming pools.The following image describes the applications of Micro CHP systems:

Currently the countries like Japan and Germany witnessing micro CHP unit sales on a large scales. Japan leads the world micro CHP market with more than 80% share in annual global sales. The U.K and U.S. are also beginning to look to distributed energy resources such as micro CHP for their energy requrements. The other areas that have witnessed micro CHP development or research activity include The Netherlands, South Korea and Canada.
