The oil and gas fired power plants e.g. coal, gas, biomass have significant costs in form of fuel cost (Raikar and Adamson, 2020). Marginal cost refers to the operating cost needed to generate a MWh of electricity. Total costs of fossil fuel power plants are dominated by fuel costs, ...
The chemical formula of JET-A1 is C12H23, and its lower heating value (LHV) is 42,800 kJ/kg [21]. The changes in potential energy within the engine are negligible. The cooling air mass flow is not considered for analysis [22]. The heat exchangers (air–fuel, fuel–oil) are not co...
The costs can be fuel (Ct,fuel), operational, and maintenance costs (Ct,OM) and the initial investment cost (Ct,inv). The LCOE however cannot be used if the energy generating technology competes with other alternatives. For example the waste heat can also be used in a district heating ...
