Germany-headed electrolysis plant specialists thyssenkrupp Uhde Chlorine Engineers GmbH has been awarded an engineering contract to install an 88 MW water electrolysis plant for green hydrogen in Varennes, Québec (QC) for Canadian energy company Hydro-Québec. The hydrogen and oxygen will be supplied to the Varennes Carbon Recycling (VCR) biorefinery that is to be built on an adjacent site (graphic courtesy Hydro-Québec).

Hydro-Québec, a state-owned company, is one of the largest hydropower suppliers in North America thanks to the enormous hydro resources available in the Canadian province of Québec.

According to a statement, thyssenkrupp Uhde Chlorine Engineers’ Green Hydrogen product division was awarded the contract after successfully completing a feasibility study,

The water electrolysis plant will be built adjacent to the planned Varennes Carbon Recycling (VCR) biorefinery in Varennes, Québec, and is to produce 11 100 tonnes of green hydrogen annually. Both hydrogen and oxygen, a by-product of the electrolysis process, will be used in the advanced biofuels plant that will produce transportation biofuels from residual waste.

This project is an excellent illustration of how important the interaction of secure access to competitive renewable energy and the use of scaled technology for hydrogen production is, said Sami Pelkonen, CEO of thyssenkrupp’s Chemical & Process Technologies business unit.

With a capacity of 88 MW, this electrolysis plant will be one of the world’s first and biggest production facilities for green hydrogen. Commissioning is scheduled for late 2023.

Québec as a region and Hydro-Québec as a customer offer ideal conditions for installing our water electrolysis technology on a multi-megawatt scale for the first time, said Denis Krude, CEO of thyssenkrupp Uhde Chlorine Engineers.

Water electrolysis a key scale-technology

According to the company, water electrolysis is the key technology for decarbonizing the industrial sector as, to date, it is the only scaled technology for producing green hydrogen.

Green raw materials only become economically viable if they are produced and used on an industrial scale, as this is the only way that scaling effects can be reflected in an improved cost structure.

thyssenkrupp’s water electrolysis technology offers the world’s largest standard modules, which can be easily combined to achieve capacities in the multi-megawatt and gigawatt range.

With the expansion of our annual supply chain to one gigawatt, our large standard modules, and the global presence of our company as an EPC supplier, we already have an ideal starting position in a market that is becoming more dynamic, said Christoph Noeres, Head of Green Hydrogen at thyssenkrupp Uhde Chlorine Engineers.
