Hydrogen can be produced more affordably

 

Lucerne – Up to 15 percent of the costs from producing hydrogen can be saved. This is the result of research from Lucerne University of Applied Sciences and Arts, which was conducted within the framework of the European project QualyGridS.

 

Specialists from the Institute of Innovation and Technology Management at the Lucerne University of Applied Sciences and Arts (HSLU) have been researching the economic added value of environmentally friendly hydrogen production. According to a press release, their work has shown that using water electrolyzers to stabilize the power grid can decrease production costs by up to 15 percent in the event of overloads or underloads.

 

Water electrolysis is the process by which energy is used to split water into oxygen and hydrogen. The efficiency of this is still problematic: heat is lost during production that cannot always be utilized well. Additionally, the price of electricity created from renewable energies is high. Both of these points make environmentally friendly hydrogen comparatively expensive at the moment. The car filling station network is also still thin on the ground. Christoph Imboden, a lecturer in energy economy at the HSLU, states: “It is only a question of time until this changes. Large-scale offensives are already being prepared in Switzerland with regard to this.”

 

The European project QualyGridS investigated a promising solution to decrease production costs along with eleven partners from eight countries. The aim of the project was to standardize prequalification tests for water electrolyzers, thereby simplifying their authorization.

 

Within the framework of this, researchers from the HSLU calculated the monetary advantage of water electrolyzers. As there is still no data basis for this, the service value had to be compiled first for the various network operators in Europe. In the end, the research group was able to determine that using water electrolyzers to stabilize the power grid reduces hydrogen production costs by up to 15 percent. According to the press release, “this makes it significantly easier to introduce hydrogen technology on a large scale.”
