How does hydrogen energy technology help to achieve carbon neutrality targets?

In recent times, the role of hydrogen technology has become more important in decarbonizing society and achieving carbon neutrality targets. However, the nexus between hydrogen technology and carbon neutrality has not received attention from the empirics. Therefore, this analysis is an effort to plug this gap in the literature by examining the role of hydrogen technology in achieving carbon neutrality targets in six top hydrogen technologies innovative and polluting economies from 1995 to 2021. This study employs the CS-ARDL to obtain the short and long-run results. According to the long-run outcomes, hydrogen technology, green ICT, and financial development cause carbon emissions to fall. In contrast, the GDP boosts the carbon emissions. On the other hand, the short-run estimates don't show any significant relationship with the carbon emissions. These results highlight the significance of hydrogen technology and suggest that policymakers should increase the role of hydrogen technology in energy and related sectors in top polluted economies to help them achieve zero-emission targets.
