The cell produces electricity through chemical reactions between hydrogen peroxide and aluminum. If perfected, such an electricity source could one day replace conventional batteries in many ...

The hydrogen economy provides an efficient and environmentally friendly pathway to store and consume energy 1,2. Fuel cells, especially the recently developed polymer electrolyte membrane fuel cells, ...

While not a primary source of energy, hydrogen, because of its large energy density, provides a vehicle with which to store and transport energy. Photoelectrochemical (PEC) cells can use sunlight to ...

Hydrogen peroxide (H 2 O 2) packs so much chemical energy into a small space that it is powerful enough to fuel rockets. But this same ability to concentrate energy also makes hydrogen peroxide useful ...

To resolve the energy crisis and environmental issues, research to move away from fossil fuels and convert to eco-friendly and sustainable hydrogen energy is well underway around the world. Recently, ...

Scientists have created a silicon-based water splitter that is both low-cost and corrosion-free. The novel device -- a silicon semiconductor coated in an ultrathin layer of nickel -- could help pave ...

From the stainless steel in wind turbines to electric vehicle batteries, nickel is playing a key role in the clean energy transition. Yet the industrial processes that make this important metal are ...

Comprising abundant interfaces, multicomponent heterostructures can integrate distinct building blocks into single entities and yield exceptional functionalities enabled by the synergistic components.

For combustion engines to use 100 percent hydrogen, they need components that can withstand high temperatures and corrosive environments. Scientists from the University of Alberta discovered a new ...
