ADVANTAGES OF DECENTRALISED, COMBINED HEAT AND POWER GENERATION
The use of CHP (Combined Heat and Power) offers besides the combined and simultaneous generation of electricity and heat a large number of advantages:
Green energy in the right place at the right time
With this method, power is generated as it is required, so that generation matches exactly with the actual consumption. During the winter, when we are at home we need both heating and a large amount of electricity. Compared to photovoltaics, a higher proportion of power needs can be generated at home, meaning that the demand of electricity from the public network is low.
No need for costly network expansion
The expansion of the power supply system that is now essential due to the increased use of renewable and fossil energy sources in centralised power plants becomes unnecessary with decentralised energy generation using CHP methods. This is because the electricity is only produced where it is required and used.
Generating electricity with a CHP system allows households and communities to produce their own power, on site and consumer oriented. Excess amount of electricity, which are not needed in the household can then be fed or even sold back into the public power supply system.
In traditional dedicated electricity power plants, the heat that is produced is disposed of in cooling towers. However, in CHP systems, this so-called "waste" heat is used and not wasted, leading to significantly higher efficiences and a reasonable and sustainable use of the heat generated.
Economical and sustainable use of energy
Compared to the separate generation of electricity and heat, cogeneration reduces the energy used and moreover the consumption of the primary energy sources needed, by more than one third.
By using responsibly sourced and local biomass as an energy source the total energy production is 100% ecological and sustainable. In this way, importing electricity generated by nuclear power and the burning of fossil fuels (e.g. heating oil) will become unnecessary. Examples of biomass CHPs are the Pellematic Smart_e and the project Pellematic e-max: pellet heating systems with integrated Stirling engine that use wood pellets as an energy source
