Hydrogen - Utilitas

Production process of green hydrogen

The inputs for green hydrogen production are green electricity and demineralized water. In the production process, no carbon dioxide is released — only pure hydrogen and oxygen.

First green hydrogen value chain in the Baltics

In 2021, the Environmental Investment Centre (KIK) organized a competition to establish a system for the adoption of green hydrogen in the public transport sector. The support round selected project, in which Utilitas produces green hydrogen, Alexela operates the refueling stations, and the investment company UG Investments acquired 30 Toyota Mirai hydrogen cars that customers can order through the Bolt app.

Production

At the Väo energy complex, Utilitas produces green hydrogen in a 1 MW plant centered around an electrolyzer developed by the Estonian company Stargate Hydrogen. The heat generated during the green hydrogen production process, which is powered by renewable electricity, can be directed into the district heating network, significantly increasing the overall efficiency of the process.

Fuelling stations

One of the fuelling stations is located next to Utilitas’ Väo energy complex, and the other at the Alexela station on Peterburi Tee. With modern technology, it is possible to fully refuel a hydrogen-powered passenger car in 3–5 minutes, and a bus or truck in 10–15 minutes

Vehicles

Hydrogen cars use hydrogen and oxygen as fuel and do not emit exhaust gases into the environment. From the exhaust pipe of an environmentally friendly hydrogen car, only a small amount of completely pure water is released
