H2 Today

our history

Notre histoire

HydrogenToday was created in 2015 with the purpose of informing people about hydrogen interest and upsides as well as its related technologies. The articles, which are written by experts, aim to make accessible to all this vast and complex subject.

H2Today daily publishes plenty of articles regarding hydrogen’s latest developments: its many applications in all fields, its industrial sector and its economic players, the ecosystems currently being deployed, and of course research and innovation.

Our experts and journalists do not simply replicate press releases or reference articles that are already published elsewhere. They do their best to provide and comment on the most relevant information in a quick-to-read format accessible to all audiences.
