Denmark: Electrolysis Technology Air Liquide Produces Carbon-Free Hydrogen at Pilot Site

Editor: Alexander Stark

Air Liquide inaugurating Hy Balance, a pilot site for the production of carbon-free hydrogen, in Hobro, Denmark. The facility uses electrolysis technology and allows to balance the electricity grid and store surplus electricity in the form of hydrogen that will be used in industry and transportation. .

Paris/France — This project, initiated in 2016, is led by Air Liquide with funding from the European public-private partnership Fuel Cells and Hydrogen Joint Undertaking (FCH JU) and the support of the Danish EUDP program (Energy Technology Development and Demonstration Programme).

As part of this project, the company developed, built, and is operating the facility that produces hydrogen from water electrolysis as well as the filling center for its customers delivered by trailers. The electrolyser, with a capacity of 1.2 MW, enables the production of around 500 kg of hydrogen a day without releasing CO2. Besides industrial customers, the hydrogen that is produced is used to supply the network of five hydrogen stations installed and operated by the Copenhagen Hydrogen Network (CHN), a subsidiary of Air Liquide in Denmark.

Denmark is a pioneer in the integration of renewable energies into the national energy mix, with 40 % of the country’s electricity produced from wind turbines. By compensating for renewable energy intermittency, hydrogen offers a solution for storing surplus electricity to meet the challenges posed by the energy transition.
