H System™ Turbine

GE's H System™ turbine is one of the most advanced gas turbines in the world, the first capable of delivering 60 percent efficiency and powerful enough to provide electricity to 300,000 American homes.

Greater efficiency means the H System uses less fuel and produces fewer emissions per megawatt of electricity generated.

GE's H System™ is one of the most advanced gas turbine combined cycle systems in the world – powerful enough to provide the electricity needed to power 300,000 American homes.

The H System™ uses an innovative closed-loop steam cooling system. This system allows the turbine to fire at a higher temperature to enable 60 percent fuel efficiency capability and helps deliver greater efficiency, reduced emissions and less fuel consumption per megawatt generated.

In addition, the H System™ offers approximately 40 percent improvement in power density per installed megawatt compared to other combined cycle systems, once again helping to reduce the overall cost of producing electricity.

A GE 7H gas turbine combined cycle system can generate enough electricity to power 300,000 U.S. homes – roughly the number of homes in Columbus, Ohio. Producing this much electricity with a 7H gas turbine combined cycle system, instead of a typical coal-fired plant, reduces emissions of a carbon dioxide by 2.1 million tons each year. That is approximately the amount of carbon dioxide that would be emitted by more than 370,000 passenger cars in a year.

A 7H gas turbine combined cycle system produces 50,000 tons fewer carbon dioxide emissions each year compared to a typical gas turbine combined cycle plant of equivalent electricity output. That is approximately the amount of carbon dioxide that would be emitted by more than 9,000 passenger cars in a year.

The carbon dioxide savings of operating the 7H gas turbine combined cycle system rather than a typical pulverized coal power plant producing the same amount of electricity, over the course of one year, would be equal to the amount of carbon dioxide absorbed by approximately 530,000 acres of forest.

A 7H gas turbine combined cycle system emits about 20 fewer tons of smog-forming nitrogen oxides and about 11 fewer tons of particulate matter than a typical gas turbine combined cycle plan producing the same amount of electricity.

Over the course of one year, the carbon dioxide savings from operating a 7H gas turbine combined cycle system rather than a typical gas turbine combined cycle plant of equivalent electricity output would be equal to the amount of carbon dioxide absorbed by approximately 12,000 acres of forest.
