Denmark's Upcoming Fuel Cell Factory Offers 90% Efficiency

The high efficiency offsets the energy loss from converting electricity to hydrogen.

Denmark has been among the leaders in Europe for green energy for years, with more than 30 percent of its energy consumption coming from renewable sources.

As a report by Innovation Origins points out, a new in-development project should help Denmark to hold onto that position.

Last week, energy firm Haldor Topsøe announced it will build a plant for “solid oxide electrolyzer cells” (SOEC).

The company claims that these SOEC fuel cells have an energy efficiency exceeding 90 percent — much greater than other fuel cells that work with liquid materials.

One of the main with hydrogen as an energy source is the energy loss that is incurred when converting green electricity to hydrogen for transportation.

'Significantly more efficient than other technologies'

Construction on the plant is set to start in 2022 and the company aims to have the facility fully operational by 2023. The capacity of the fuel cells in the first year will be 500 megawatts and has the capacity to be expanded to 5 gigawatts in the near future.

"With this new production plant, we want to play a leading role in the energy transition to a low-emission future," says Roeland Baan, CEO of Haldor Topsøe.

"We are convinced that one of the most promising routes to this goal lies in the efficient use of green electricity for hydrogen production," he continues. "With our SOEC electrolysis technology, more than 90% of the renewable electricity entering the electrolysis is retained in the form of green hydrogen. This is significantly more efficient than other technologies currently available on the fuel cell market."
