What is Cogeneration?

Cogeneration, also known as CHP or ‘Combined Heat & Power’, is an electricity generation method that works on capturing the losses typically suffered by traditional electricity generation processes. In its most basic form, it is the generation of both electricity and usable heat through an efficient ecological method of power production. The levels of fuel utilised in this kind of process sit at around 92%, meaning the losses incurred are considerably less than conventional energy generation (which is about 40%!).


So, how does a CHP cogeneration system work?

It may seem complex, but the premise behind how a cogeneration plant works isn’t as complicated as it appears. To begin, diesel, gas or Biogas are used as fuel for a CHP engine. That fuel is burnt in the engine in order to produce power, and an exhaust gas heater exchange grabs the heat from the engine, which is where cogeneration steps in. It captures both the heat from the exhaust gas heater and the engine, resulting in the production of high efficiency heat. A heat exchanger then processes the heated water, releasing the applicable heat product to a secondary circuit. The secondary circuit is what is used to heat your household items, such as taps or air-conditioning, or other heat requirements. Then the power created by this method is produced by the alternator, which turns engine power into electrical power. The result is both heat and electricity that can be used for a large array of purposes, all whilst offering an eco-friendly method.

What are the benefits of cogeneration?

There are varying reasons why people are considering different energy methods and it really depends on the individual as to which option they choose, however there are considerable benefits to a CHP cogeneration system, including but not limited to :

  • Higher efficiency levels
  • Consistent stable electricity
  • Reduced overall running costs
  • Reduced energy wastage
  • Less wasted heat energy
  • The creation of two forms of energy (electricity and heat)
  • Thermal energy generation
  • Lower heating costs
  • Reduced carbon footprint
  • Backup power supply
  • More eco-friendly!

The environmental benefits of cogeneration are huge, which is enough in itself to consider making the switch.
