Clean Energy

PSM is committed to providing innovative solutions to meet the energy needs of our customers today and in the future.

Your Partner for Innovative Clean Energy Solutions for Future Generations

Across our business, we are committed to creating a more sustainable future by providing our customers with clean energy solutions that will deliver clean, flexible, efficient, and reliable power to share with future generations.

Renewable and clean gases like hydrogen can be the fuel source in gas turbine power plants. PSM actively works with customers to upgrade existing gas turbines with reliable, cost-effective solutions utilizing alternative fuel options. PSM retrofit gas turbine technologies reduce carbon intensity with neutral solutions for power generation.

Solving the energy trilemma

The energy trilemma refers to the challenge of balancing three aspects of energy systems: environmental sustainability, energy affordability, and energy reliability. PSM assists plant operators in achieving their decarbonization goals for their installed fleet of gas turbines. Achieving these three goals helps our customers meet the challenges today and in the future.

Advantages Of retrofitting and upgrading For Clean hydrogen fuel:

  • Reduced carbon emissions: Hydrogen is a clean-burning fuel that produces zero carbon emissions when combusted. By retrofitting gas turbines to run on hydrogen, power plants can significantly reduce their carbon footprint and contribute to ongoing efforts to combat climate change.
  • Greater fuel flexibility: Your turbine will be able to run on 100% methane gas to 100% hydrogen.
  • Improved efficiency: Hydrogen has a higher energy content per unit volume than natural gas. With PSM power retrofits, plants running can achieve higher power output and improved efficiency.
  • Reduced maintenance costs: Our combustion retrofits are designed to meet the demanding needs of the operator, resulting in reduced maintenance costs over time.
  • Asset Optimization: By upgrading your existing turbine for enhanced operational and clean fuel flexibility, equipment can be profitably repurposed and future-proofed for decades to come.
  • Energy security: Hydrogen can be produced domestically from a variety of sources, including natural gas, biomass, and renewable energy sources (such as solar and wind). This reduces our dependence on foreign oil and enhances energy security.
  • A cleaner grid: Gas turbines running on hydrogen can provide cleam firming and peak power capacity, which can help stabilize the power grid during periods of high demand and/or intermittency of renewable energy generation.

Overall, retrofitting gas turbines to run on hydrogen can offer significant benefits in terms of reduced carbon emissions, greater fuel flexibility, improved efficiency, reduced maintenance costs, and improved grid stability.

Hydrogen Color Spectrum

The terms gray-, blue-, green-, pink- and turquoise-hydrogen are energy industry terms used to describe different technologies for producing hydrogen and associated environmental impact. Each color code on the hydrogen color spectrum corresponds to a unique hydrogen production method.  Here is a brief overview of the different types of hydrogen:


Grey hydrogen

  • Derived mainly from natural gas using a process called steam methane reforming (SMR)
  • Carbon byproduct released into atmosphere


Blue hydrogen

  • Derived from fossil fuels using the SMR process with carbon capture and storage (CCS)
  • Minimal carbon footprint


Green hydrogen

  • Derived from renewable energy sources (i.e., solar or wind) through electrolysis
  • Produces no carbon emissions


Pink hydrogen

  • Derived from nuclear energy through electrolysis
  • Produced with no carbon emissions


Turquoise hydrogen

  • Derived using methane pyrolysis to make hydrogen and solid carbon
  • May be valued as low-emission if powered by renewable energy and carbon is stored or used

How PSM Converts a Gas Turbine to Run on Natural Gas And/or Hydrogen Fuel

  • Determine the turbine's compatibility with hydrogen: The first step is to determine whether the gas turbine is compatible with hydrogen. This involves analyzing the turbine's design, materials and operating parameters to ensure safe operation with hydrogen fuel.
  • Modify the fuel system: The next step is to modify the existing fuel system to accommodate hydrogen. This involves either modifying or replacing the natural gas with a fuel flexible supply system. This encompasses installing a blending and delivery system.
  • Modify the combustion system: Retrofit/Install a PSM Flamesheet™ or LEC III™ combustion system.
  • Test and commission the turbine: After upgrades are completed, the turbine needs to be systematically tested to ensure safety and efficient operation. Verify performance improvements and emission reductions.

PSM has a team of engineers and technicians who specialize in gas turbine conversions and can help customers navigate the process. A detailed assessment of the plant and decarbonization goals are required to specify the scope of the conversion.
