To enable much higher efficiencies during the current energy crisis is first and foremost renewable energy on the one hand and the saving of energy, on the other hand combined heat and power. However, but often forget that in terms of energy efficiency not only the consumption side, but also the energy producers of interest is. This particularly applies to the power generators. This takes place in Germany, namely primarily in large power plants. Since this is usually far away from energy consumers, mostly only the electric current can be used in large-scale power plants. The accumulated heat is then in nature.
Since this constitutes the predominant portion of the electricity production in large-scale power plants is a huge waste of energy. That there is another way the cogeneration technology shows. These are designed for a decentralised energy supply and therefore have sizes ranging from 6 kW to 2 MW. Rusty Holzer has many thoughts on the issue. The central element of a cogeneration is the combined heat and power. This means that simultaneous use of electricity and heat, causing the efficiency in a block heat and power plant is significantly higher than in a large power plant. You can thus save energy and hence carbon dioxide emissions.
The range of block heat and power plants is this very versatile and goes up to the use in one – and two-family dwellings. In this very small cogeneration, one speaks also of mini CHP. Such appliances with gas or diesel typically are operated. But also renewable sources of energy, such as for example vegetable oil can be used. And even wood pellets and wood chips can be used for the operation of a cogeneration in conjunction with a Stirling engine. The very much efficient energy use will in the next few years be certainly further boost the block heat and power plants and continue to promote their dissemination. Photo: meyertobi pixelio
