InsigH2t aims to advance the current scientific understanding regarding the effect of pressure on the turbulent burning rate, thermoacoustic
response, and emissions performance of premixed hydrogen flames under relevant gas-turbines operating conditions. Hydrogen, with its
high diffusivity and reactivity, poses significant challenges to its clean and efficient utilisation as a fuel in gas-turbines, due to the lack
of understanding of its pressure-dependent turbulent burning rate, crucial for combustion stability in gas-turbines operation. InsigH2t
leverages high-pressure experimental measurements, featuring advanced optical diagnostics, coupled to cutting-edge direct numerical
simulations, focusing on a selection of simple canonical flames that are paradigms of more complex industrial burner geometries
and configurations. The fundamental insights gained will facilitate the development of advanced models and enhanced design tools,
empowering industrial OEMs to reduce the significant development time and costs of hydrogen combustion technologies. By leveraging
science-based predictive capabilities, InsigH2t aims to accelerate the deployment of clean, reliable, and efficient hydrogen-fired gas
turbines. The project's impact extends beyond scientific understanding, addressing directly relevant industry challenges. Crucially, the
involvement of two gas turbine OEMs ensures full alignment with the Strategic Research and Innovation Agenda of the Clean Hydrogen
Joint Undertaking, facilitating the swift transfer of improved combustion methodologies and understanding towards application in
operational power plants. Ultimately, InsigH2t's contributions align fully with the objectives of the EU Green Deal, reducing dependency
on fossil fuels and offering a tangible pathway towards a more sustainable energy future.
