SANTA CLARA, Calif. -- Heading to an event at the Santa Clara Convention Center, Levi's Stadium, or California's Great America theme park and running low on your electric vehicle (EV) charge? There are no worries in Santa Clara as the city has one of the largest public multi-standard EV charging facilities in
Reaction mechanism with a catalyst for fuel cells that use hydrogen and carbon monoxide as fuels.
Kyushu University, I2CNER
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.
University of Adelaide
Australian scientists have paved the way for carbon neutral fuel with the development of a new efficient catalyst that converts carbon dioxide (CO2) from the air into synthetic natural gas in a 'clean' process using solar energy.

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.
Chalmers University of Technology
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.
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.

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.
University of Illinois at Urbana-Champaign
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

One of the biggest hurdles to the widespread use of hydrogen fuel is making hydrogen efficiently and cleanly. Now researchers report in the journal ACS Nano a new way to do just that. They incorporated a photocatalyst in a moisture-absorbing, semiconducting paint that can produce hydrogen from water in
Dr. Mahmoud Dhimish's research will mean low energy bills for consumers.

In the UK alone, some 1.5 million homes are equipped with solar panels, and it has been estimated that by 2020 the figure could soar to 10 million, with the prospect of lower energy bills for consumers and massive reductions in CO2 emissions. Now, a University of Huddersfield researcher is developing new technologies
Proton hopping plays an important role in the reaction, as it activates nitrogen gas even at low temperatures and moderates the harsh condition requirements.

Our society is in need of ammonia more than ever.
Chemical fertilizers, plastic, fibers, pharmaceuticals, refrigerants in heat pumps, and even explosives all use ammonia as raw material. Moreover, ammonia has been suggested as a hydrogen carrier recently because of its high hydrogen content.

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.
