            1 million  tons of hydrogen  per  year.  As shown  in Figure 2,  NortH2 includes  the production  of
            hydrogen, storage, transportation via pipelines, and distribution.

            HYDROGEN COULD BRING SOLUTIONS TO LONG-TERM ENERGY
            STORAGE

            The NortH2 experiment is also a very good business case to evaluate the potential of using hydrogen
            as energy storage, solving a problem faced by many renewable energy farms when having an excess of

            electricity that they’re unable to supply to the grid, as happened in Australia and at mega wind farms.                Power Semiconductors


            Although the conversions of renewable energy to hydrogen using electrolyzers, and hydrogen to                          Play a Critical Role in
            electricity using fuel cells, are not very efficient today, progress has been made and research is
            progressing well. As shown in Figure 3, when stored, hydrogen remains available for a very long
            period compared with other methods and in very high volumes. Fuel cells can be turned “on” on                          Efficiently Powering
            demand to supply the grid when peaks arise.

            The NortH2 experiment is just one example out of many showing how hydrogen will contribute to

            producing carbon-free energy and provide high-capacity energy storage.
