A novel technical solution to produce climate-friendly green hydrogen will soon be developed in Estonia. Stargate Hydrogen and Tallinn University of Technology (TalTech) have signed a cooperation agreement for the joint development of a next-generation electrolyser. An electrolyser is used to transform water into oxygen and hydrogen by using an electric current. When using green energy as input, an electrolyser can produce hydrogen without any CO2 emissions. The new device allows the production of climate friendly green hydrogen more efficiently and at lower cost.

In the TalTech Department of Materials and Environmental Technology, three Stargate Hydrogen scientists have already started the first stage of the project, a nanoceramic material synthesis. Synthesised materials will later form the core of the electrolyser.

“In cooperation with TalTech, we can do top-level research and development,” Rainer Küngas, CTO at Stargate Hydrogen says. “Our aim is to bring the novel technology into mass production as soon as possible. We are excited to see the next results of our R&D, and we see several opportunities for extending the cooperation with the university in future. Reducing hydrogen production costs is one of the most important measured in order to get rid of the dependency on natural gas, which largely comes from Russia, and thus achieve energy security.”

The electrolysers being developed do not need precious metals to produce hydrogen, and they are highly efficient as they produce green hydrogen at lower costs than existing solutions. While the first stage of the project is focusing on the development of materials and equipment, the second stage would be the automation of manufacturing of electrolysers, and the development of machine learning solutions. Hydrogen related legislation also needs to be prepared in Estonia.

According to Dr Küngas, the right partners and a strong team are needed to achieve the goals. Dr Jan Gustav Groling, for example, the former Head of Technology in the Swiss company Hexis, a leading high temperature fuel element manufacturer, recently joined the company.

“Stargate Hydrogen is a quickly developing, ambitious hydrogen technology developer. TalTech is honoured to have been selected as a cooperation partner by Stargate Hydrogen,” Sven Illing, Vice-Rector for Entrepreneurship at TalTech comments. “We see a big future for hydrogen technology, and we want to be pioneers here.”

Stargate Hydrogen, a private company, is developing turnkey solutions for green hydrogen deployment. The innovation of the company is focused on the development of a next-generation electrolyser, and fuel-cell based solutions in the railway sector.

Tallinn University of Technology is a research-based university where scientific achievements have an output in the learning activity and in business cooperation. Tallinn University of Technology cooperates with other top-level universities, scientists, and companies all over the world.
