SP2 will contribute to the goal of LowEmission through R&D of GT combustion concepts for H2/N/NH3 firing, with the aim of achieving a 100% reduction of the CO2 emissions from GTs.

In close collaboration, researchers, PhDs/ PDs and industry partners will investigate the potential use of H2/NH3 fuels by: i) targeted improvements to current combustor technology and, ii) developing new combustion concepts.

Objectives:

  1. Investigate and develop existing and new GT combustor concepts using H2/NH3 fuels
  2. Combustor development for retro-fit: Investigate the potential of H2/NH3 firing in existing non-premixed burner designs deployed in the installed GTs fleet and assess retro-fit solutions
  3. Train a new generation of engineers in cutting edge theory, experiments and simulations to transfer knowledge, ensure industry competitiveness, and deliver new technical innovations

The SP conducts research and develop- ment of gas turbine combustion concepts for hydrogen, and ammonia firing, with the aim of achieving a 100% reduction in CO2 emissions from gas turbines. The potential use of these fuels will be investigated through targeted improvements to current combustion technology and the development of new combustion technology.

Main objective

The overarching objective of SP2 is to advance the capabilities for carbon-free firing of the gas turbine fleet (existing and future) relevant for deployment on the Norwegian Continental Shelf (NCS). The proposed research approach in SP2 follows two main tracks:

  1. WP1, NH3/H2/N2 blending: The first track will investigate how to optimize hydrogen blending with opportune carbon-free diluents, such as ammonia/nitrogen, that act to reduce hydrogen reactivity to obtain a step-in fuel for natural gas. This will provide the GT-manufacturer with guidelines for optimal operation and improved design of the combustion system.
  2. WP2, Flamesheet: The second track will focus on the gas turbine combustion system handling of hydrogen reactivity without dilution, which potentially offers more robust aerodynamics that are flashback resistant.

Main results

The main results in 2019 relate to the planning and organization of upcoming experimental and numerical campaigns in the two tracks, in addition to organization activities associated with research collaborations. The following list of deliverables and milestones has been realised:

  • A contract has been signed with Robert Barlow, to work collaboratively with TU Darmstadt on fundamental measurements of ammonia/ hydrogen flames structure.
  • An experimental plan for SGT750-type burner pressurized combustion testing with ammonia/hydrogen/nitrogen fuel blends has been made.
  • An experimental plan for Flamesheet-type burner pressurized combustion testing with undiluted hydrogen has been made.

Impact and innovations

The work in SP2 is not yet at a stage where impact and innovation can be accurately assessed.
