Hydrogen Technologies vs. Battery Ones in the Green Energy Transition

Dear Colleagues,

The transition to an economy with an exponentially reduced environmental impact is now obligatory. In this context, two major technologies can enable the exploitation and full utilisation of renewable energy sources: one operates using hydrogen and the other via batteries. These are thus two seemingly contrasting but complementary technologies. This Topic aims to present scientific articles highlighting (the list is only partial) the pros and cons of both technologies, comparing them and showing their areas of use, the social and economic aspects of their application, as well as the technological and infrastructural challenges, fundamental/key research issues, regulations, test protocols and costs. In addition, state-of-the-art analyses/reviews are also welcome. In summary, we aim to provide an overview of the two technologies in order to enable the reader to form an opinion exclusively based on the results of scientific research.
