Carnot method

<p>The Carnot method is an allocation procedure for dividing up fuel input (<a href="/facts/Primary_energy/GD65dbDA">primary energy</a>, end energy) in joint production processes that generate two or more energy products in one process (e.g. <a href="/facts/Cogeneration/nuSxEoqP">cogeneration</a> or trigeneration). It is also suited to allocate other streams such as <a href="/facts/CO2_emissions/Cu9nXPHE">CO2-emissions</a> or variable costs. The potential to provide physical work (<a href="/facts/Exergy/HNF7KAmc">exergy</a>) is used as the distribution key. For heat this potential can be assessed the <a href="/facts/Carnot_efficiency/MtLN7MfQ">Carnot efficiency</a>. Thus, the Carnot method is a form of an exergetic allocation method. It uses mean heat grid temperatures at the output of the process as a calculation basis. The Carnot method's advantage is that no external reference values are required to allocate the input to the different output streams; only endogenous process parameters are needed. Thus, the allocation results remain unbiased of assumptions or external reference values that are open for discussion.
