Air Injection Technology - Turbophase 

Turbophase: Air Injection Technology That Transformed the Power Industry

Our patented Turbophase technology is a modular air injection system, or “Turbo Charger,” that is compatible with every combustion turbine and solves one fundamental problem that all combustion turbine plants must face: sensitivity to ambient temperature changes. Our solution offers continuous, reliable power under any ambient conditions, resulting in greater output and improved efficiency.

How Turbophase Works

Install Turbophase Module

First, our above-ground skid-mounted Turbophase modules are installed on efficient reciprocating engines that burn either natural gas or diesel.

Turbophase Air Injection in a Power Plant

Increase Mass Flow

Each Turbophase module houses a multi-stage inter-cooled centrifugal compressor which injects hot, high-pressure air directly into the compressor discharge plenum of the CT, resulting in an increased mass flow through the combustor and turbine.

Experience Increased Output

By using the waste heat from the reciprocating engine to heat up the air to gas turbine compressor discharge temperature, we then inject that super fuel-efficient air into the gas turbine compressor discharge. The Turbophase engine produces compressed air ~40% more efficiently than the axial compressor of the gas turbine.

Solving the Perennial
Gas Turbine Dilemma

The challenge faced by all gas turbines is that as ambient temperature or elevation rises, the density of the air naturally decreases, reducing the mass flow into the gas turbine and thus resulting in lower output.

Turbophase (air injection technology) restores the mass flow that is naturally missing by injecting hot air "mass" into the compressor discharge. The combustion turbine control system maintains constant firing temperature, generating 10-20% more power.

Economical, Long-Term Solution to Maximize Plant Output

The Turbophase system can be installed for a much lower capital cost than a new gas turbine or OEM upgrade. Turbophase enables combustion turbines to operate up to the plant's electrical limits in all ambient conditions, regardless of temperature or altitude, and responds quickly with additional incremental megawatts. The technology has a life-span of 30+ years.

Leverage Your Most Efficient Assets for a Greener Tomorrow

Power plant owners can leverage Turbophase's rapid-response peaking combined cycle power to reduce the amount of time they run their less efficient machines, resulting in decreased net carbon output.

OEM-Friendly Technology

Our Turbophase modules are OEM-friendly as there is no maintenance penalty associated with the injection of dry air in CCGT. OEM literature states that combustion turbines are designed for 5% injection. Injecting 5% air with a Turbophase system results in a 10% power increase for the plant.

Compatible Engines
& Flexible Plant Layout

Powerphase’s modular system is built to work on any type of combustion engine, anywhere. Our modules have the ability to be sited up to 1 kilometer from any given combustion turbine, and can be placed on top of an existing structure or run from a barge.

Quick & Simple

Turbophase is able to be deployed relatively quickly compared to other technologies and requires only 1-3 days plant outage, whereas other technologies can take up to a 60 day outage to install. Our average lead time for installation is less than 10 months. Air Injection technology is benefitting plants around the world.

Case Studies


Southeast Asia

Scalable Power to Match Industrial Park Growth in Southeast Asia

Powerphase engineers estimate that the power plant could increase its generating output by 10 percent, with 8 Turbophase modules, while building out far less than tenth of the plant’s current footprint. The high-tech park uses all of the plant’s power, and anticipates significant growth.


Saudi Arabia

More Power & Efficiency on a 7FA in the Middle East

Powerphase demonstrated two Turbophase modules on a GE 7FA.03gas turbines at the SEC Faras power plant. The technology proved to be flexible, highly available, and that it could improve gas turbine heat rate performance by 5% during Saudi Arabian summers.

More Power & Flexibility Lead to Profits at a Cogen Plant in PJM

Each Turbophase module boosted GT performance by 3.2 MW and ST performance by 0.45 MW, for a total plant performance boost of 7.3 MW. Since the initial 2014 installation and testing at the Morris plant, Powerphase engineers have improved Turbophase efficiency. Today, Turbophase systems achieve 10% additional flow by optimizing the compressor for a lower pressure ratio used by the B/E class gas turbines.



Florida Grid Efficiency: Equal to Removing 1 Million Cars from the Road

Accounting for natural gas capacity boost and displacing coal-fired capacity, by implementing Turbophase, the FRCC can avoid $96 million in energy costs per year for Florida ratepayers. Reducing inefficient peaking plant and coal-fired electricity generation is also an environmental win, reducing acid rain causing SO2 emissions by 14.2 thousand tons per year, and globally polluting CO2 emissions by 4.8 million tons per year, equal to 1 million cars being taken off Florida’s roadways.
