    "TECNALIA will develop combustion tests with different gases and mixtures"

    TECNALIA promotes the H2Al initiative to move towards more sustainable industry

    H2Al aims to accelerate the transition to a more sustainable industrial model through the use of hydrogen-basedadvanced technologies. It came about with the aim of exploring new technological solutions applied to the manufacturing industry, integrating the potential of hydrogen as a key energy carrier in the decarbonisation of industrial processes.

    In this context, the initiative addresses the challenges faced by the sector, focusing on an approach aligned with the principles of Industry 5.0, in which sustainability, digitalisation and the human factor play a key role.

    • TECNALIA seeks to generate knowledge and validate innovative technologies to increase energy efficiency, reduce emissions and optimise production processes.
    • The project also focuses on the application of digital tools, such as Digital Twins, which facilitate data-driven decision-making and the design of more efficient and resilient systems.
    • Furthermore, it is committed to a collaborative approach, involving different actors of the industrial and technological ecosystem, in order to drive knowledge transfer and encourage the adoption of innovative solutions in the business sector.

    Combustion tests with different gases and mixtures

    TECNALIA will develop combustion tests with different gases and mixtures, including up to 100% H2 at a new test plant with capacity of up to 1 MW and with the ability to control the different process parameters and advanced simulation.

    On the other hand, the project’s final industrial demonstrator will be an aluminium maintenance melting tower, working with oxy-combustion of hydrogen for at least 1,000 hours to determine the real effect on the refractory, metallurgical quality, costs and emissions.
