A new wave of zero-emission economy

We truly care about climate – we are all affected, no matter where we live on Earth. And that has led us on a crucial journey of breakthrough green energy technologies replacing fossil fuels. We simply have an obligation to provide these alternatives to guarantee a better place to live for the next generations.

Green hydrogen plays a central role in the decarbonisation of several industrial sectors as well as transport. While there are several ways to produce hydrogen, the most sustainable one with minimal environmental impact is combining clean electricity with electrolysis to split water into hydrogen and oxygen.

We need a new wave of sustainable energy solutions, and we need them now.

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 and zero-emission locomotive 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.

Zero-emission locomotives
Stargate provides zero-emission locomotives for the freight sector which eliminate emissions and reduce cost. Our approach is to electrify locomotives without the need for overhead catenary lines. Hydrogen and battery hybrid locomotives offer the fastest and cheapest way to electrify rail transport since there is no need to re-build existing infrastructure.

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 are in tune with the need to 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.

Our management team

Hydrogen means the stars to us!
