Project description
Simulating hydrogen combustion to achieve decarbonisation
Hydrogen combustion can reduce carbon emissions in transport, industry and other energy-intensive sectors, but accurate simulation remains costly because hydrogen flames involve complex turbulence and differential diffusion. Supported by the Marie Skłodowska-Curie Actions programme, the H2SAFIRE project is developing a hybrid modelling framework combining large eddy simulation (LES), an adaptive linear eddy model (LEM) and a reduced order model based on a deep neural network (ROM-DNN). The ROM-DNN surrogate replaces costly LEM calculations when reliable, while an uncertainty-aware gate falls back to the LEM when needed to preserve accuracy. The framework will be validated on canonical and industrial-like flames. H2SAFIRE aims to deliver faster, reliable hydrogen combustion simulations, thereby supporting cleaner energy solutions, reducing costs and strengthening Europe’s leadership in hydrogen technologies.
Objective
Reaching climate neutrality by 2050 requires deep decarbonisation of transport, industry and other energy-intensive sectors where fossil fuels still dominate. Hydrogen is a zero-carbon energy carrier whose safe, efficient use depends on fast and trustworthy predictions of turbulent flames. For large-scale devices, however, high-fidelity Large Eddy Simulation (LES) is costly because hydrogen combustion couples multiscale turbulence with differential diffusion and intermittent local ignition and extinction. H2SAFIRE proposes a hybrid modelling framework that couples LES with a Linear Eddy Model (LEM) for micro scale chemistry and a Reduced Order Model based Deep Neural Network (ROM-DNN) surrogate trained on LEM data. The surrogate replaces the costly chemistry step when reliable; a calibrated uncertainty gate monitors confidence at run time and reverts to LEM whenever uncertainty exceeds a threshold, preserving physical fidelity.
The project pursues three objectives. First, design and validate an adaptive LES-LEM solver tailored to hydrogen combustion. Second, construct a physics-guided LES-LEM-ROM-DNN framework in which ROMs compress LEM outputs and a DNN predicts modal dynamics in loop to supply sub-grid source terms. Third, evaluate accuracy, robustness, generalisation and efficiency on canonical and semi-industrial flames, targeting at least a ten-fold speed-up at matched fidelity. Validation uses a jet-in-hot-coflow flame and an industrial-like furnace.
H2SAFIRE will release an open solver, FAIR datasets, benchmark cases and practical guidelines for hydrogen combustion simulations. By enabling faster and reliable predictions, the project can lower modelling cost and energy use, support cleaner industrial heat and transport, and strengthen European capability for hydrogen technologies. Training at UPM and a secondment at ULB ensure rigorous validation and knowledge transfer. The outcomes align with the European Green Deal and the UN Sustainable Development Goal.
