Many new power plants utilize CCGTs. Stationary CCGTs burn natural gas or synthesis gas from coal. Ships burn fuel oil. Multiple stage turbine or steam cycles can also be used, but CCGT plants have advantages for both electricity generation and marine power. The gas turbine cycle can often start very quickly, which gives immediate power.
For power generation applications, the investment costs are cheaper than combined cycle combustion turbine plants (in 2003, the Energy Information Administration estimated that the cost of a combined cycle plant was US$500–550/kW, as opposed to the SCCT cost of US$389/kW [1]), but at reduced efficiency. SCCTs require smaller capital ...
Compressed natural gas (CNG) is a fuel gas mainly composed of methane (CH 4), compressed to less than 1% of the volume it occupies at standard atmospheric pressure.It is stored and distributed in hard containers at a pressure of 20–25 megapascals (2,900–3,600 psi; 200–250 atm), usually in cylindrical or spherical shapes.

The General Electric LM6000 is a turboshaft aeroderivative gas turbine engine. The LM6000 is derived from the CF6-80C2 aircraft turbofan.It has additions and modifications designed to make it more suitable for marine propulsion, industrial power generation, and marine power generation use.
Steam at ordinary process heating conditions still has a considerable amount of enthalpy that could be used for power generation, so cogeneration has an opportunity cost. A typical power generation turbine in a paper mill may have extraction pressures of 160 and 60 psi (1.10 and 0.41 MPa). A typical back pressure may be 60 psi (0.41 MPa).
