Power augmentation gas turbines to support renewables

A Snapshot of Your Day

As the world strives to decarbonize the electricity sector via higher shares of renewables, there is a growing demand of additional stability mechanisms supporting our electrical grids. Historically and worldwide, gas turbines have with their flexibility contributed to the robust and resilient electricity supply we enjoy today, but further strengthening of their ability to fast and flexible load transitions are now desirable. Different power augmentation methods are therefore more frequently being applied, typically adding compressor inlet cooling or water injections to traditional gas turbine plants.

A promising novel concept is large scale air injection, main reasons are the smooth and seamless activation to meet all sorts of grid stability requirements and the time shift of energy. The time shift of energy is yet another argument for air injection since it is a good match to the nature of grids dominated by solar and wind power. The round-trip efficiencies of an “air battery” added to turbo machineries, forming an extra “diabatic Compressed Air Energy Storage” dCAES, are approaching what can be accomplished by traditional batteries.

There are several challenges with a dCAES as a power augmentation system added to turbo machineries. In this master thesis, we would like to reflect on all aspects but having focus on one specific topics, or perhaps two in case two students can team up.

The challenges and topics to be addressed are

• Air storage alternatives (rock, salt, seafloor ballons, tanks, pipelines…) and their features
• Conceptual design of dCAES added to a gas turbine
• Impact on gas turbine design
• Techno-economical study of alternative concepts
• Detailed case study in a collaboration with a power producer

How You’ll Make an Impact

• Deeper understanding of challenges with more renewables in the grids
• Value of improved flexibility of gas turbine plants
• Knowhow in one, or two in case of two students, of the key topics
• Provide yet another piece in the puzzle towards decarbonization

What You Bring

• Master of Science in Mechanical, Chemical, or Geological Engineering, or an equivalent field
• Curious mind, eager to be a part of the energy transition
• Scientific skills in one of the areas of aerodynamics, thermodynamics, grid stability and geological formations
• Fresh and innovative thinking

About the Team

Within the R&D department we have specialists with a profound knowledge about energy production and power plant alternative concepts, both from a theoretical viewpoint, but also from practical design aspects. You will be part of this environment. We also work closely with power producers and could form a team with a more practical real scenario and case study.

Our Gas Services division offers Low-emission power generation through service and decarbonization. Zero or low emission power generation and all gas turbines under one roof, steam turbines and generators. Decarbonization opportunities through service offerings, modernization, and digitalization of the fleet.

We can offer you employment benefits such as: reduction of working hours, advance vacation, health care allowance and an eventual possibility to a flexible working place.
