Our mission
The research spans from fundamental science to applied research in the domaine of renewable energy storage by means of hydrogen and its derivatives. Investigation of reaction mechanism especially for hydrogen interacting with metals and carbon as well as analysis of energy systems in order to substitute fossil fuels with renewable energy. Search for new creative and innovative solutions and working beyond the obvious.
Research topics | |
|---|---|
| 1 | Interaction of hydrogen with metals, hydrogen intercallation and structure of hydrides. |
| 2 | Reduction of CO2 and carbon hydrates with hydrogen, synthetic hydrocarbons as sustainable fuels for the future renewable energy economy. |
| 3 | Analysis of the technical requirements and economic impacts of renewable energy systems. |
Our key projects
Metal hydride storage
In collaboraion with Korean groups and GRZ Technologies a energy storage system is developed consisting of an electrolyzer from Korea and a metal hydride storage system from Switzerland. New hydrides based on bcc alloys allow to almost double the hydrogen storage density.
Biogas to Pure Synthetic Methane
Conversion of biogas to pure methane in collaboration with Gaznat. Hydriding the CO2 to synthetic methane in the presence of 50% methane after prior removal of the catalyst harming impurities. The methanation reaction leads to >99.6% of Methane in a one stage reactor. The impurities are separated from the biogas by new nanoporous membranes.
Palm Oil to Sustainable Aviation Fuel
Efficient synthesis of sustainable aviation fuel from palm oil by introducing a selective cracking and hydrogenation. Therefore, more than 75% of the input carbon is conserved in the desired product.
Our results and highlights | |
|---|---|
| 1 | Publications on hydrides are the most cited in the field. Significant contributions hydrogen interaction with nanomaterials, metals and carbon. |
| 2 | Watt d’Or award, Hydrogen and Energy award |
| 3 | Long term international collaborations with leading groups in China, Japan, Korea, USA, and several European countries that led to many publications. |
| 4 | A series of patents on hydrides, catalysts, analytical techniques and applications are used in industry. |
| 5 | First description of the technical oportunities and economic impact of a complete transition of Switzerland to renewable energy: Andreas ZÜTTEL, Christoph NÜTZENADEL, Louis SCHLAPBACH, Paul W.

Team & talents
The team consists of 2 post docs, 7 PhD students and 2 to 5 internship students
Several former group members are now professors e.g. Wen LUO at Shanghai University or Emanuele MOIOLI at Poletechnico in Milano. Several group members have successfully created companies e.g. Noris GALLANDAT GRZ Technologis SA and Cedric KOOLEN SCIDENTIFY SA.
The learn to work not only on scientific interesting research topics but also to work on relevant scintific challenges and to produce valuable results beyond measurements.
Contribution to the knowledge of the global science comunity by exchange and collaborating with the best scientists world wide.
Regional and social impacts | |
|---|---|
| 1 | Renewable energy storage is the key technology needed in order to substitute the fossil fuels with renewables. The development of new new materials and technologies as well as the science directly serve the society. |
| 2 | The increasing contribution of renewable energy to the energy mix is a key topic in Valais. New technologies create new activities, work and prosperity. |
| 3 | The energy transition to renewables is also a transition of the energy market. The economy profits from the knowledge created about the future technologies. |
| 4 | The contributions to the Swiss hydrogen association Hydropole (www.hydropole.ch) and the International Symposium Hydrogen & Energy (www.hesymposium.ch) links us within the Swiss energy network and the international comunity. |
Perspectives and challenges
Priority 1
Hydrogen in metals and the properties of hydrides
Priority 2
Sustainable aviation fuels from biological oil
Priority 3
Renewable energy system analysis
Main challenges
Focus on the promotion of natural intelligence and profit from rather than substitute with artificial intelligence in order to concentrate on the most relevant topics for the benefit of humanity.
Future Partnerships
Increase the collaboration with China and concentrate on the best Chinese research groups to profit from the synergies to create mutual success.
