A hydrogen and solar-powered demonstration river vessel has been developed as part of Bulgaria's first multidisciplinary projects involving industry, local government and business. The project was implemented under the National Science Programme "Low Carbon Energy for Transport and Domestic Use (EPLUS)" by a research team of Ruse University "Angel Kanchev", with the participation of scientists from BAS and Technical University - Sofia. HydRUforce is a demonstration vessel with hybrid propulsion based on solar energy - battery - hydrogen fuel cell and has zero carbon emissions. With the realization of the project, Bulgarian scientists are involved in the research on the use of low-carbon energy in Europe's inland water transport. A pontoon with a solar roof was used for the hull of the vessel. All its [...]
