How the fast-ramping 9000HL gas turbine supports your path to net-zero

There is not just one solution which will produce enough power and meet net zero emissions targets. A mix of new technologies, including high output and fuel-flexible options like the SGT-9000HL, are paving the way to sustainable energy. Whether you’re switching from coal to gas, to higher efficiency solutions, or to low- and no-carbon fuels, we’re with you on this journey. Integrating with renewables and carbon capture storage technologies are also ways the SGT-9000HL can help you drive the energy transition.

Hydrogen power plants

TÜV SÜD Certification for power plants with SGT-9000HL gas turbines

In October 2023, we have received the TÜV SÜD certificate for the hydrogen readiness concept covering combined cycle plants, simple cycle plants and combined heat and power plants equipped with the SGT-9000HL. With this certificate, TÜV SÜD validates the readiness concept for main systems and components with exception of the gas turbine package for hydrogen readiness up to 100% hydrogen. The gas turbine package itself is rated as H2 ready for up to 50%Vol, based on current rig test results.


This is an important milestone in the 9000HL’s hydrogen journey as TÜV SÜD is an internationally recognized certifier, and this certificate is evidence that we meet the requirements to offer hydrogen-ready power plants in line with regulatory requirements, customer expectations and transformation roadmaps. We are aiming to have all gas turbines capable of burning 100% hydrogen by 2030, to help our customers meet their demands of the energy transition.

Ease that you deserve

Complementing the HL gas turbine, our innovative GT Auxiliary Integrated Package (AIP) provides you with smart, streamlined construction and servicing.  

  • 20K hours saved in construction
  • Fully electrically integrated
  • 95% of all inline components integrated
  • Fast Stack modules give assurance of fit-up in the field
  • Modules are truck shippable
  • Design fully developed in-house, built to print
  • Allows for maintenance during operation
  • Lighting system integrated

Service for your solution

  • Industry leading service intervals for advanced gas turbines with the first outage at 33,000 EBH / 1,250 ES
  • Ability to rotor de-stack on site and no rotor inspection recommended until 200,000 EBH/ 5,000 RES for hours based units
  • Minimized outage durations through pre-designed serviceability features of the package and engine, for example, the capability to perform a Combustion Inspection + Row 1 Outage requiring no turbine cover lift instead of a traditional Hot Gas Path Inspection
  • The frame is fully integrated into Siemens Energy service concept offerings 


Making an impact with HL gas turbines

SSE is very pleased to have this unique opportunity now to partner with Siemens Energy. The highlight efficient technology, not previously seen in the UK, will provide firm, reliable power at half the carbon emissions of the coal generation it is replacing.

Martin Pibworth, SSE Wholesale Director

This unique arrangement with Siemens Energy offers a significant cost saving to our customers while providing one of the most advanced, efficient gas turbine units in the U.S. This new technology will provide us with flexible peaking power needed to complement intermittent solar energy resources for our customers and lower emissions across our fleet.
