HELION Presents Its Hydrogen Electric Generator at the Monaco Hydrogen Forum
We were pleased to unveil our new hydrogen power generator at the Monaco Hydrogen Forum, organized by the Monaco Hydrogen Alliance. This event brought together important professionals and experts to discuss the challenges related to hydrogen and was very successful. The forum featured a rich program of high-quality conferences, showcasing the advancements and prospects of hydrogen as a renewable energy source. During this meeting, an international working group was established to focus on the use of hydrogen in coastal areas. This group aims to explore how different stakeholders can collaborate to effectively integrate hydrogen into transportation, whether by sea or land. This demonstrates everyone's commitment to a more environmentally friendly economy. Another highlight of the forum was the presentation of the Monaco Hydrogen Innovation Award by H.S.H. Prince Albert II of Monaco. This award recognizes projects that promote the use of hydrogen and support research in this field. For HELION, the most significant moment was the presentation of our hydrogen power generator, which offers zero-emissio solutions. This genset is designed to replace diesel solutions used in stationary applications.
