The partnership between Helen Oy, MAN Energy Solutions, and H-TEC SYSTEMS in Finland aims to establish a 3MW green hydrogen production plant near Helsinki's district heating network and Vuosaari Harbour. Green hydrogen, produced through PEM electrolysers powered by renewable energy sources, is gaining traction globally for its environmental benefits. The EU's ambitious goals to produce and import significant amounts of green hydrogen by 2030 reflect the increasing demand for sustainable energy solutions. MAN Energy Solutions will handle the engineering, procurement, and construction of the hydrogen plant, while H-TEC SYSTEMS will provide the PEM electrolysers. The collaboration emphasizes the use of green hydrogen in various sectors like industry, transportation, and heating. The innovative 3H2 project represents a groundbreaking initiative integrating different sectors for sustainable energy production and demonstrates the potential of green hydrogen as a key player in the transition towards cleaner energy sources.
