Multifunctional catalyst for poison-resistant hydrogen fuel cells

Reaction mechanism with a catalyst for fuel cells that use hydrogen and carbon monoxide as fuels.

Kyushu, Japan--Demand for eco-friendly fuel sources is increasing as the goal of weaning off our reliance on fossil fuels becomes commonly recognized. Hydrogen represents a possible sustainable fuel source when it is produced from water and burned with oxygen because only water is released as a by-product. The

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton conductivity is crucial for the latter; protons, i.e. positively charged hydrogen ions, are formed from hydrogen, which is used to power the fuel cell.

Deceleration of runaway electrons paves the way for fusion power

Although the vacuum chamber in the British fusion reactor JET has a wall made of solid metal, it can melt if it gets hit by a beam of runaway electrons. It is these runaway elementary particles that doctoral students Linnea Hesslow and Ola Embréus have successfully identified and decelerated.

Fusion power has the potential to provide clean and safe energy that is free from carbon dioxide emissions. However, imitating the solar energy process is a difficult task to achieve. Two young plasma physicists at Chalmers University of Technology have now taken us one step closer to a functional fusion reactor.

Changing how solar power rolls

Smaller and lighter than traditional solar panels, the Roll-Out Solar Array, or ROSA, consists of a center wing made of a flexible material containing photovoltaic cells to convert light into electricity.

Traditional solar panels used to power satellites can be bulky with heavy panels folded together using mechanical hinges. An experiment that recently arrived at the International Space Station will test a new solar array design that rolls up to form a compact cylinder for launch with significantly less mass

Corn better used as food than biofuel, study finds

In a new study, Professor Kumar and graduate student Meredith Richardson find that using corn for biofuel comes with greater environmental costs and fewer benefits than using corn for food.

Corn is grown not only for food, it is also an important renewable energy source. Renewable biofuels can come with hidden economic and environmental issues, and the question of whether corn is better utilized as food or as a biofuel has persisted since ethanol came into use. For the first time, researchers at

Researchers Compute their way Toward Cleaner Coal Plants

Using the HLRS Hazel Hen machine, RWTH Aachen University researchers were able to run a DNS simulation on a system of 45,000 particles at the Kolmogorov scale. To the team's knowledge, this is the direct-particle simulation for the largest number of particles at this scale to date, and serves as a benchmark for how other researchers studying this process can get more realistic simulation results.

When you think of turbulence, you might think of a bumpy plane ride. Turbulence, however, is far more ubiquitous to our lives than just air travel. Ocean waves, smoke from fire, even noise coming from jet engines or wind turbines are all related to turbulence. A team of researchers at RWTH Aachen

Chemical 'Dance' of Cobalt Catalysis Could Pave way to Solar Fuels

Argonne chemists Dugan Hayes, Lin Chen, and Ryan Hadt have identified a rapid electronic process that could aid the water-splitting reaction in cobalt-containing catalysts. Cobalt catalysts are relatively inexpensive and could replace more expensive precious metal catalysts in the production of clean energy, most notably solar fuels.

By splitting a water molecule into two atoms of hydrogen and one of oxygen, scientists can use the boundless energy of the sun to make a clean fuel.
