A new wave of zero-emission economy

We accelerate progress towards an emission-free future through our sustainable end-to-end green hydrogen solutions.

This is us

Stargate is a high-growth deep-tech company headquartered in Tallinn, Estonia. Stargate is a pioneer in next generation green hydrogen production solutions.

Next generation alkaline electrolysers
Stargate is developing novel ceramics-based electrode materials that bring high efficiency at low cost. The ceramics-based alkaline electrodes contain no precious metals, resulting in significantly lower hydrogen production costs while maintaining excellent efficiency. We are concentrated on two customer segments – electrolyser end-users and other electrolyser system manufacturers.
We offer electrolysers designed for industrial sector end-users such as refineries, green ammonia producers, utility companies, etc. And we also offer our stacks as components to electrolyser system integrators.

Part of a large industrial group of companies
Stargate Hydrogen is part of UG Investments group of companies. Investments of the group include Utilitas, the largest renewable energy producer in the region.

We operate with the next generation in mind

We have established a Rising Star scholarship and we offer internship possibilities for STEM students. These initiatives were established to give back to the community that creates and defines our future.
