A joint research team from the Helmut Schmidt University/ University of the Bundeswehr in Hamburg and the Helmholtz Zentrum Hereon has developed and presented an innovative metal hydride compressor system. For the first time, hydrogen takes on a dual function: it serves not only as the medium to be compressed...

In Japan, alongside rapid population aging, the number of older adults living alone is increasing. New research has revealed that rapid demographic changes—population aging together with the increase in single-person households—pose structural risks for both decarbonization and energy sufficiency. Addressing this challenge will require the redesign of cross-sectoral policies extending...

A month into war with Iran, the U.S. government has opened its strategic oil reserve and temporarily lifted sanctions against Russian (and Iranian) oil and gas to combat rising fuel prices and calm financial markets. Even if the conflict ended today, energy experts estimate a ripple effect could last months...

New types of semiconductor devices that respond to light could be possible using materials called perovskites, according to a new study by researchers at the University of California, Davis. The work, published in Advanced Materials, shows that halide perovskite crystals reversibly change shape when exposed to light....
