When Electrons "Jump" into Water: The Secret Behind High Electrode Capacities

Researchers decode how minimal "electron spillover" increases energy storage capacity tenfold

27-Jun-2025 - In order to develop improved electrolysers for regenerative hydrogen production, the processes on the surfaces of the metal electrodes used must be precisely understood. Researchers from the Theory Department at the Fritz Haber Institute have now been able to show that even the smallest spillover ...

Renewable gas from hydrogen and CO₂

New sorption-enhanced methanation plant at Empa

18-Jun-2025 - On June 16, Empa inaugurated its novel methanation plant. The move-MEGA research project is the first to demonstrate so-called sorption-enhanced methanation at pilot scale – a technology developed at Empa that makes the power-to-gas process more flexible and robust. The produced synthetic methane ...

Roadmap for linking CO2 sources and sinks using electrochemical processes

Opportunities, challenges and potential for improvement in the large-scale integration of CO2 sources and electrolyzers

17-Jun-2025 - What are the most promising CO2 point sources? How can the maturity of different reactor designs be determined? And which target product has the highest drop-in market potential? There are still some unanswered questions on the way to the industrialization of CO2 electrolysis. Answers are ...

Green hydrogen from Africa much more costly than previously assumed

Imports without guarantees are not competitive

10-Jun-2025 - To meet Europe’s demand for green hydrogen, governments and the private sector have high hopes for production in Africa. A study led by the Technical University of Munich (TUM) has now shown that the financing costs for production facilities in African countries would be much higher than ...

New method for sustainable recycling of rare earths from electrolysers

Turning old into new

05-Jun-2025 - Hydrogen electrolysis cells contain rare earth metals. Once an electrolysis cell has done its job, the materials used in it currently end up as scrap steel. A research team at TU Bergakademie Freiberg is now investigating how the recyclable materials can be recovered from used electrolysis cells ...

New Prospects for Green Ammonia

Study provides a blueprint for load-flexible production plant – and lower costs

04-Jun-2025 - Converting ammonia production to a low-emission process is one of the major challenges in the fight against climate change. Ammonia, one of the most widely produced chemicals worldwide, is essential for the fertilizer industry and, in turn, the production of plant-based foods. However, its ...

Green hydrogen: MXene boosts the effectiveness of catalysts

Promising path to a new class of catalysts

02-Jun-2025 - MXenes are adept at hosting catalytically active particles. This property can be exploited to create more potent catalyst materials that significantly accelerate and enhance the oxygen evolution reaction, which is one of the bottlenecks in the production of green hydrogen via electrolysis using ...

thyssenkrupp nucera and Fraunhofer IKTS open First SOEC Pilot Production Plant for Stacks for the Production of Green Hydrogen

30-May-2025 - thyssenkrupp nucera and Fraunhofer IKTS opened the first SOEC pilot production plant for electrolysis stacks on May 27 in Arnstadt, Thuringia, in the presence of high-ranking representatives from science, politics, and industry. The event was also attended by the Minister President of the State ...

How gas bubbles influence hydrogen production

New findings are relevant for all electrolysis processes

28-May-2025 - Electrolysers are a key technology for the energy transition. They split water into hydrogen and oxygen, but still consume too much electricity in the process. One challenge is that the initially dissolved hydrogen separates in the form of gas bubbles, which can seal off the electrode - at the ...
