New system for widespread availability of green hydrogen

Hydrogen researchers and Graz-based start-up developed a cost-effective process for the decentralised production of high-purity hydrogen

27-May-2020

As an alternative propulsion technology in the transport sector, hydrogen is playing an important role in the energy transition. However, it is not yet suitable for mass production. Hydrogen is mainly produced centrally from fossil resources and compressed or liquefied in an expensive and ...

Electrolysis: How to produce better electrodes

Another step forward for renewable energies: The production of green hydrogen could be even more efficient in the future

15-May-2020

By applying an unusual process step, chemists at Martin Luther University Halle-Wittenberg (MLU) have found a way to treat inexpensive electrode materials and considerably improve their properties during electrolysis. Hydrogen is thought to be the solution to the storage problem of renewable ...

Energy of the future: photosynthetic hydrogen from bacteria

How cyanobacteria can be transformed into hydrogen factories

06-May-2020

The transition from fossil fuels to a renewable energy supply is one of the most important global challenges of the 21st century. In order to achieve the internationally-agreed target of limiting global warming to a maximum of 1.5 degrees, the international community must drastically reduce ...

Superconductivity: It’s Hydrogen’s Fault

With new nickelates and the predictive power of supercomputers to the superconductor without any cooling

29-Apr-2020

Nickel is supposed to herald a new age of superconductivity – but this is proving more difficult than expected. Scientists at TU Wien (Vienna) can now explain why. Last summer, a new age for high-temperature superconductivity was proclaimed - the nickel age. It was discovered that there are ...

Water splitting observed on the nanometer scale

New method provides fundamental insights into electrocatalytic water splitting under operating conditions

06-Mar-2020

Whether as a fuel or in energy storage: hydrogen is being traded as the energy carrier of the future. To date, existing methodologies have not been able to elucidate how exactly the electrochemical process of water splitting into hydrogen and oxygen takes place at the molecular scale on a ...

Effective way to obtain fuel for hydrogen engines

24-Feb-2020

One of the most promising alternative energy sources is hydrogen, which can be extracted from water and air. A catalyst is needed for a chemical process that releases hydrogen from an H2O molecule. It can be made, for example, from platinum, or from molybdenum. But these are quite expensive ...

Chemists develop safer hydrogenation processes

12-Feb-2020

Safe and environmentally-friendly hydrogen gas on demand could be on the horizon following a new "hydrogenation" chemical process in development at The City College of New York. Led by Mahesh K. Lakshman, the research uniquely bypasses the need for an external source of hydrogen gas to accomplish ...

Visualizing chemical reactions

On the way to synthetic fuels

10-Jan-2020

Researchers at the joint EPFL-Empa lab in Sion have developed a reactor system and an analysis method that has allowed them to observe the real-time production of synthetic natural gas from CO2 and H2 for the first time. Infrared (IR) thermography is used to determine the temperature of humans ...
