In a long-running collaboration with GE Aerospace, researchers at the University of Melbourne in Australia have been steadily working to improve the performance of high-pressure turbine (HPT) engines through computer simulations on leadership-class computing systems. These turbines are the heart of jet engines used in many commercial and military aircraft....

To ensure energy security and achieve its climate protection goals, Germany will import large quantities of hydrogen in the future. Dimethyl ether (DME) is an environmentally friendly, non-toxic, efficient, and economically attractive gas that shows great promise as an energy source for hydrogen and its derivatives. The Fraunhofer Institute for...

Demand-side flexibility, the ability to adjust electricity consumption in response to system needs, is often highlighted as a key tool for managing both growing electrification and a higher share of variable renewable energy, and is therefore seen as a core part of the energy transition. In the article Command and...

A little-known fact: In the year 1900, electric cars outnumbered gas-powered ones on the American road. The lead-acid auto battery of the time, courtesy of Thomas Edison, was expensive and had a range of only about 30 miles. Seeking to improve on this, Edison believed the nickel-iron battery was the...
