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.
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.
2006: Westport HD Engine and LNG Fuel System for heavy-duty trucking applications was launched. The HPDI technology is based on the 15-litre Cummins ISX but is adaptable to other OEM engines as well. 2008: Westport formed a joint venture with Weichai Power, China's largest heavy-duty engine manufacturer, and Hong Kong Peterson (CNG) Equipment ...

Methane, the main component of natural gas, has an autoignition temperature of 580 °C, [47] whereas gasoline and diesel autoignite at approximately 250 °C and 210 °C respectively. With a compressed natural gas (CNG) engine, the mixing of the fuel and the air is more effective since gases typically mix well in a short period of time.
The fuel used is typically natural gas. Gas engine CHP plants use a reciprocating gas engine, which is generally more competitive than a gas turbine up to about 5 MW. The gaseous fuel used is normally natural gas. These plants are generally manufactured as fully packaged units that can be installed within a plantroom or external plant compound ...
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 ...
