A new model now describes the boiling process with much greater precision
When a liquid boils in a vessel, tiny vapor bubbles form at the bottom and rise, transferring heat in the process. How these small bubbles grow and eventually detach was previously not known in any great detail. A German-Chinese research team under the leadership of the Helmholtz-Zentrum ...
Newly discovered effect boosts productivity of green hydrogen transport processes
Catalysts are of utmost relevance for the production of chemicals and energy storage with hydrogen. Researchers at the Helmholtz Institute Erlangen-Nürnberg for Renewable Energy (HI ERN) and Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have now discovered that the formation of bubbles ...
BASF Stationary Energy Storage GmbH (BSES), a wholly owned subsidiary of BASF SE, and G-Philos, Korea’s leader in power-to-gas (P2G) technology, signed a sales and marketing agreement for NAS batteries (sodium-sulfur stationary batteries) for P2G projects, power grid and microgrid applications. ...
The results provide clues to increase the efficiency of photocatalysts
Certain metal oxides are considered good candidates for photocatalysts to produce green hydrogen with sunlight. A Chinese team has now published exciting results on copper(I) oxide particles in Nature, to which a method developed at HZB contributed significantly. Transient surface photovoltage ...
Engineers develop stable devices that don’t require expensive iridium
Creating ahydrogen economyis no small task, but Rice University engineers have discovered a method that could makeoxygen evolutioncatalysis in acids, one of the most challenging topics in water electrolysis forproducing clean hydrogen fuels, more economical and practical. The lab of chemical ...
This technique paves the way for large-scale hydrogen storage in solids
Hydrogen gas could someday replace fossil fuels as a “clean” energy source, producing only water and energy. However, handling large quantities of gaseous hydrogen is cumbersome, and converting it to a liquid requires vessels that can withstand extremely high pressures. Now, researchers reporting ...
Hydrogen has the highest energy density (120 MJ/kg) of all known substances, approximately three times more than diesel or gasoline, meaning it could play a pivotal role in sustainable energy systems. But the efficient production of hydrogen by simple water splitting requires highly performing ...
German-South African Consortium starts working to optimise the production of sustainable kerosene
The international research project CARE-O-SENE (Catalyst Research for Sustainable Kerosene) was granted 30 million euros in funding by the German Federal Ministry of Education and Research (BMBF). Additionally, the industrial consortium partners contribute 10 million euros. The aim of the project ...
In order to produce green hydrogen, water can be split up via electrocatalysis, powered by renewable sources such as sun or wind. A review article in the journal Angewandte Chemie Int. Ed. shows how modern X-ray sources such as BESSY II can advance the development of suitable electrocatalysts. In ...
Progress has been made on the path to sunlight-driven production of hydrogen
Chemists from Würzburg present a new enzyme-like molecular catalyst for water oxidation. Mankind is facing a central challenge: it must manage the transition to a sustainable and carbon dioxide-neutral energy economy. Hydrogen is considered a promising alternative to fossil fuels. It can be ...
