Early-career researcher wins €67,000 for Power-to-X breakthrough

10 December 2021

A decades-old riddle is being solved by Anne Lyck Smitshuysen of the Technical University of Denmark, paving the way for cheaper production of green hydrogen and winning her the Flemming Bligaard Award.

Green hydrogen is widely regarded as a leading alternative to fossil fuels, but price remains a major barrier. Hydrogen is three times more expensive than fossil fuels and is first expected to be cost-competitive by 2030. That’s a major brake on the transition to low-carbon energy at a time when acceleration is urgently needed.

But now, pioneering research from 28-year-old Danish researcher Anne Lyck Smitshuysen could make large-scale generation of hydrogen from renewable energy sources viable within this decade. 

On 10 December, she won the 2021 Flemming Bligaard Award and a cash prize of €67,000 for demonstrating how to increase the size of the cells used to produce green hydrogen, thereby cutting total costs by as much as 15%. 

“Through my research, I have shown how to increase the size of electrolysis cells from 150 square centimeters to 1,000 square centimeters without breaking the cells during construction. That’s roughly equal to upscaling the quadratic cells from the size of a piece of toast to the size of a computer screen,” she says.

Robert Arpe, chairman of the Ramboll Foundation, expects the innovation to accelerate the green energy transition on a global scale: 

“Anne Lyck Smitshuysen’s invention is a technological breakthrough in Power-to-X research which will have a tremendous impact on the future production of green hydrogen,” he says. The €67,000 award will fund Anne Lyck Smitshuysen’s future research. 

Making more robust electrolyser cells

Green hydrogen is produced through a process known as electrolysis. Electrolysis occurs when the cells in an electrolyser are activated by an electrical current and split water molecules into their constituent parts – oxygen and hydrogen. 

Because the cells are thin and delicate, they often curl at the edges during production when they are heated to 1,300°C, rendering them unusable. This is why Smitshuysen’s solution, which she developed while she was on maternity leave, is so innovative. 

“I realised that by using a 3D-printed cast to mould the cells in a way that corresponds to the shrinkage caused by the heating process, the size of the cells could be increased by 500 percent,” she explains.

Speeding up deployment of Power-to-X

The European Union expects green hydrogen to meet 24% of global energy demands by 2050, but the sooner the technology reaches scale, the larger impact it will have on total emissions reductions. 

According to Søren Højgaard Jensen, CEO of the electrolyser startup DynElectro where Anne Lyck Smitshuysen is currently working on her PhD, her breakthrough may accelerate Power-to-X production by as much as 15 years. 

About the Award

The Flemming Bligaard Award, named in honour of former Ramboll CEO and chairman of the Ramboll Foundation, is given annually to an early career academic, whose work has made an outstanding contribution to sustainable development. 
Last year, the Award was given to UK-based architect and researcher Colin Rose for his work on cross-laminated secondary timber to replace concrete in the building industry. 

Ramboll’s Power-to-X footprint

Since 2020, Ramboll has worked on more than 60 Power-to-X projects and studies, which includes several 1 GW projects. In Denmark, Ramboll has provided high-level support on master planning the world’s first artificial energy island, which is expected to be the largest infrastructure project in Danish history.
