What Is a Gas Turbine?

A gas turbine—an advanced propulsion and power-generation system—is composed of a compressor, combustion chamber, and power turbine. These systems burn fuels such as natural gas, diesel, or biogas under high pressure to generate powerful rotational energy. Sharing design lineage with jet engines, gas turbines are compact, lightweight, and capable of rapid startup—making them invaluable for modern applications where reliability and efficiency are key.

Classification and Versatility

Gas turbines are classified across multiple dimensions:

• By Power Output:

  • Micro turbines: <300 kW

  • Small turbines: 0.3 MW – 20 MW

  • Large turbines: >20 MW

• By Application:

  • Aerospace turbines

  • Marine propulsion turbines

  • Industrial turbines: including power generation, mechanical drive, and backup systems

• By Structural Design:

  • Heavy-duty turbines (e.g., for utility-scale plants)

  • Aeroderivative turbines (optimized for peak load support)

  • Micro gas turbines (for distributed energy systems)

• By Firing Temperature:
  Classified into E, F, G, and H classes, based on turbine inlet temperature, efficiency, and operating lifespan.

Powering the AI Age: Gas Turbines in Data Centers

Gas turbines are emerging as mission-critical components in AI data centers, where power continuity is paramount. With battery storage only viable for short-term outages, onsite gas turbine generation offers a scalable, low-emission, and fast-start backup solution—capable of supporting data centers’ 24/7/365 operational demands.

For example, diesel generators at large-scale cloud facilities such as Amazon’s UK tech parks are facing increasing scrutiny due to emission regulations. Gas turbines, emitting nearly 60% less CO₂ per kWh than coal or diesel, are rapidly becoming the preferred choice for both reliability and environmental compliance.

Sustainability & Energy Transition

In Asia, over two-thirds of global gas turbine construction projects are underway, with countries like China and India leading the charge. Key drivers include:

• Decarbonization goals and a move away from coal

• Rapid industrialization and urbanization

• Short construction timelines and load-balancing flexibility

Meanwhile, in the U.S., although most large-capacity turbines were built between 2000–2005, data center development is expected to drive the next wave of installations.
