Elcogen, an Estonian developer of
solid oxide fuel cell (SOFC) and electrolysis technologies, has opened a new 14,000 square meter manufacturing plant in Tallinn. Dubbed ELCO I, the facility represents a significant leap in production scale—from 10 MW to 360 MW—positioning the company as one of Europe’s
key fuel cell manufacturers.
This strategic expansion comes amid rising global demand for clean, decentralized energy technologies. Elcogen’s systems are used across a range of applications, from industrial backup power and distributed generation to green hydrogen production and
Power-to-X projects. Rather than delivering end-use products, Elcogen supplies critical components—cells, stacks, and modules—that are integrated into energy systems by global partners.
Delivered on schedule and on budget, the facility was built in partnership with local construction firm Maru Ehitus AS. Backed by EUR 50 million in private funding and an additional EUR 25 million commitment from the European Innovation Fund, the plant is equipped to meet industrial-scale production requirements while staying aligned with environmental targets.
Power for the facility is sourced from the nearby
Iru Waste-to-Energy Plant, offering a 9 MW energy supply. Additional features such as thermal oxidizers and process heat recovery systems contribute to minimizing operational emissions and lowering overall energy intensity.
Elcogen’s CEO Enn Õunpuu noted that the site is more than just a capacity boost;
“As demand for reliable Solid Oxide-based clean energy solutions accelerates worldwide, Elcogen is now uniquely positioned to deliver the high-performance technology the market needs, at commercial volumes.” The Tallinn plant also serves as a blueprint for future international expansion, where Elcogen aims to license both its technology and production models to selected global partners.
Localization, Licensing, and the Future of Clean Energy Manufacturing
Elcogen’s growth strategy underscores a shift toward localized clean tech manufacturing and stronger supply chain resilience. With governments worldwide increasingly focused on energy security, Elcogen plans to license its production processes and intellectual property to enable in-region manufacturing for key partners. This not only supports faster adoption of fuel cell systems but also aligns with national policies that encourage domestic energy production.
The Tallinn facility is expected to support around 300 jobs as production ramps up. The company already employs a team of nearly 150 from over 20 different countries, bringing together a cumulative 500+ years of experience in solid oxide technology. This diverse workforce is a central part of Elcogen’s ability to serve global integrators while maintaining a strong European base.
The facility’s launch event brought together over 300 industry leaders, partners, and investors from across Europe, North America, and Asia. Hydrogen Europe CEO Jorgo Chatzimarkakis shared a message highlighting Estonia’s innovation leadership, saying “Estonia has once again proven its extraordinary creativity and productivity in clean-tech innovation. With Elcogen’s new facility, Europe gains a powerful boost in electrolysis and fuel cell capacity - technologies that are inseparable from the hydrogen economy. The roots of excellence now bear fruit on an industrial scale. This makes us proud as Europeans: hydrogen is the people’s molecule, and Estonia shows how to turn vision into reality.”
Elcogen, established in 2001, has transitioned from a core technology developer to a strategic supplier supporting a wide range of sectors including combined heat and power (CHP), industrial hydrogen production, and next-generation EV charging infrastructure. With ELCO I, the company signals a new phase of commercial readiness, contributing to the broader acceleration of the global hydrogen economy.
