power at low speeds and switch to traditional internal-combustion at higher speeds. Since the capability of a secondary battery is not enough to replace the existing engine, it still needs to have both battery-powered motor and engine to generate enough power.

The second stage takes the cleaned gas and burns it in a conventional gas turbine to produce electrical energy, and the hot exhaust gas is recovered and used to boil water, creating steam for a steam turbine which also produces electrical energy. In typical plants, about 65% of the electrical energy is pro
