One element, different ways to produce it<\/h2>\n\n\n\n

Hydrogen is the most abundant element in the universe, however on our planet we only find it bound to other elements, such as oxygen or carbon. In fact, it is called an energy vector<\/strong>, and not a source, as we must use energy to separate and extract it, and this kind of process has costs.<\/p>\n<\/div><\/div>\n\n\n\n

    Hydrogen has different names depending on how it is produced,<\/strong> and the resulting environmental impact<\/strong> of the processes used to obtain it.<\/p>\n\n\n\n

    One of the main methods by which hydrogen generation can take place is by electrolysis<\/strong>, a process known as early as the nineteenth century, in which the passage of electric current through water causes it to split into oxygen and hydrogen gases.<\/p>\n\n\n\n

    Hydrogen produced using renewable energy sources<\/strong> is called green hydrogen<\/strong>, which is currently produced through two main technologies: alkaline (AEC), and proton exchange membrane (PEM).<\/p>\n\n\n\n

    Some studies are now focusing on new ways to obtain it<\/strong> by exploiting the activity of red bacteria, cyanobacteria, and microalgae, as well as the gasification of municipal solid waste and non-recyclable plastics, through the decomposition of organic matter with thermal treatments at high temperatures in a nearly oxygen-free atmosphere.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n\n\n\n

    A new technology for hydrogen production<\/strong><\/h3>\n\n\n\n

    Hyter<\/strong><\/a>, a company part of the Pietro Fiorentini Group since 2021, has developed a hydrogen generator based on innovative AEMWE, Anion Exchange Membrane Water Electrolyser<\/strong>, technology.<\/p>\n\n\n\n

    <\/div>\n\n\n\n
    \"hyter<\/figure>\n\n\n\n
    <\/div>\n\n\n\n

    The electrolyser supplied by Hyter combines the advantages of both PEM and alkaline systems<\/strong>, allowing reduced investment costs and lower environmental impact<\/strong> thanks to reduced use of noble metals.<\/p>\n\n\n\n

    Ion exchange takes place through a polymer membrane produced in-house by Hyter. This membrane contains electrolytic substances that improve the efficiency of water splitting and has the function of separating hydrogen and oxygen already during the production phase.<\/p>\n\n\n\n

    This technology is much less expensive chemically and at the same time possesses excellent efficiency in terms of yield.<\/p>\n\n\n\n

    The electrolyser supplied by Hyter will be used within a project for PLT Energia<\/strong>, a company that has been presiding over the entire value chain of renewables for 15 years. The new Hyter electrolyser will interface with the photovoltaic system operating on the buildings of PLT Energia: in this way, it will be possible to produce the hydrogen needed to guarantee the environmental sustainability of the electrical and thermal consumption of their headquarters.<\/p>\n\n\n\n

    Hyter<\/strong> was recently awarded one of MiTE’s calls for tenders with the Sirius project<\/strong>, which involves the construction within three years of the world’s first electrolyser with a size greater than one megawatt based on AEMWE technology<\/strong>, Anion Exchange Membrane Water Electrolyser. The Sirius project, which in addition to Hyter also has the participation of INRETE Distribuzione Energia<\/a> (Hera Group), MatRes<\/a> (MBN Nanomaterialia Group) and the Department of Chemical Sciences at the University of Padua<\/a>, ranked third <\/strong>in the category \u201cMission 2 – Component 2 – Investment 3. 5 – Hydrogen Research and Development\u201d among the fifty-six proposals submitted to the Italian Ministry of Ecological Transition to receive European Union funding provided under the PNRR<\/strong>, National Economic Recovery and Resilience Plan.<\/p>\n\n\n\n
