Greener hydrogen from water

The idea of using hydrogen as the basis of a clean sustainable energy source, often termed a hydrogen economy, has been a topic of conversation for decades. Hydrogen fuel, for example, doesn't emit any carbon dioxide and ...

A hydrogen sensor that works at room temperature

Researchers at TU Delft have developed a highly sensitive and versatile hydrogen sensor that works at room temperature. The sensor is made of a thin layer of a material called tungsten trioxide.

How do we make hydrogen from coal, and is it really a clean fuel?

Energy giant AGL this week unveiled plans to produce hydrogen power at its Loy Yang A coal station. But how do we transform coal, which is often thought of as simply made of carbon, into hydrogen – a completely different ...

Hydrogen extraction breakthrough could be game-changer

Researchers at KTH Royal Institute of Technology have successfully tested a new material that can be used for cheap and large-scale production of hydrogen – a promising alternative to fossil fuel.

Ultrathin black phosphorus for solar-driven hydrogen economy

Hydrogen as a fuel source, rather than hydrocarbons like oil and coal, offers many benefits. Burning hydrogen produces harmless water with the potential to eliminate carbon dioxide emissions and their environmental burden. ...

Scientists build hydrogen sensor readable with the naked eye

According to many scientists, the proposed hydrogen economy, positioning hydrogen as the most important carrier of sustainably generated energy, is an inevitable development. Unfortunately, the use of hydrogen entails certain ...

Electronic entropy enhances water splitting

Researchers have long known that cerium is the best element to use when splitting water into hydrogen and oxygen—a key technique in creating hydrogen gas for fuel. But why, exactly, cerium is so successful has been far ...
