Cornerstone laid for Elcogen’s new factory

On June 18th, the cornerstone for Elcogen’s new factory was laid in the Loovälja Industrial Park near Tallinn. The 14,000 square meter factory will significantly increase the Company’s current production capacity of solid oxide cells and stacks to meet the growing global demand for emission-free energy and green hydrogen-producing fuel cells.


The factory is being constructed in collaboration with Maru Ehitus AS. Elcogen’s production capacity will increase from 10 megawatts to 360 megawatts following completion of the new facility. Construction of the factory began in January 2024, with production expected to start in mid-2025.

The cornerstone for the building was Elcogen’s elcoStack®, a fuel stack consisting of over a hundred fuel cells which produces either emission-free electricity or hydrogen through an electrochemical reaction.

Enn Õunpuu, founder and CEO of Elcogen, stated at the cornerstone ceremony that this is a crucial milestone on the path to innovative energy solutions: “The new factory will be equipped with the latest available technology, reducing its environmental impact and minimising air pollution. Production will be significantly more automated, faster, and of higher quality than before. The new factory is a priority development for us, as our current production capacity is at its maximum, and with our strategic investors Baker Hughes and HD Hyundai, we have global customers who are in need of our technology.”

Margo Dengo, Chairman of the Board of Maru Ehitus, added: “All big things start small. I am pleased to see the progress made to date – from a brief phone call with Enn back in November 2022, our journey has led us to the cornerstone laying today. This is an extremely important project for Maru Ehitus as well as a major construction challenge, due to the complexity of the systems being installed.”

Currently, Elcogen has a 1,700 m² factory in the Ülemiste district, which was completed in 2014, also in collaboration with Maru Ehitus AS.
