Hydrogen

Recently, scientists from the Swiss research institute EMPA, along with colleagues from the University of Basel and the Argonne National Laboratory in Illinois took a cue from photosynthesis and discovered that by coupling a light-harvesting plant protein with their specially designed electrode, they could substantially boost the efficiency of photo-electrochemical cells used to split water and produce hydrogen - a huge step forward in the search for clean, truly green power.  Read More

With hydrogen atoms consisting of just a single electron and single proton, its gaseous form made up of two hydrogen atoms can be hard to contain. Hydrogen storage, along with hydrogen production and the lack of infrastructure, remains a major stumbling block in efforts to usher in hydrogen as a replacement for hydrocarbon-based fuels in cars, trucks and even homes. But with the multiple advantages hydrogen offers, developing hydrogen storage solutions has been the focus of a great deal of research. Now an MIT-led research team has demonstrated a method that could allow hydrogen to be stored inexpensively at room temperature.  Read More

Currently, the world economy and western society in general runs on fossil fuels. We've known for some time that this reliance on finite resources that are polluting the planet is unsustainable in the long term. This has led to the search for alternatives and hydrogen is one of the leading contenders. One of the problems is that hydrogen is an energy carrier, rather than an energy source. Pure hydrogen doesn't occur naturally and it takes energy - usually generated by fossil fuels - to manufacture it. Now researchers at Pennsylvania State University have developed a way to produce hydrogen that uses no grid electricity and is carbon neutral and could be used anyplace that there is wastewater near sea water.  Read More

Two of the different shapes in which graphene grains can form, using traditional productio...

Graphene, the "wonder material" composed of single-atom-thick carbon sheets, is currently finding its way into a variety of electronic devices including computer chips, capacitors, transistors and batteries, just to name a few. It is typically created using a chemical vapor deposition process, in which carbon-containing gases are made to decompose on a copper foil substrate. The performance of the material may be limited, however, due to the fact that the individual graphene grains in one sheet are not of a consistent size or shape, and usually are larger than a single crystal. That could be about to change, though, as a new production method that utilizes hydrogen gas is promising higher-performance graphene with uniform, single-crystal grains.  Read More

EADS has used the opening day of the 2011 Paris Airshow to showcase an aircraft of the future concept which contemplates speeds beyond Mach 4, meaning it could make the run from Tokyo to London in under 2.5 hours. The ZEHST (Zero Emission Hypersonic Transport) study incorporates three different propulsion systems and could carry passengers to heights of 100,000 feet (32 km) while still meeting the projected European Commission targets for reduced noise, CO2 and NOX emissions by 2050. Blue sky indeed!  Read More

The go anywhere Aqua hybrid hovercraft concept

This futuristic, zero emissions hovercraft concept won't be gracing our wilderness zones any time soon but it definitely merits a mention. Dubbed the "Aqua Volkswagen," the concept was created by Zhang Yuhan, a 21 year old graduate in Industrial Design at Xihua University, China. The concept is a finalist submission in the CDN China Car Awards, a competition created to reward the creativity of young designers. The brief for entrants was to create a "Chinese off-road vehicle" by Volkswagen with "go-anywhere" capabilities to tackle the vast expanse of wild countryside in China.  Read More

After spending 70 days driving through 14 countries on four continents, three Mercedes-Benz hydrogen cell vehicles have successfully completed their 30,000-kilometer (18,641-mile) F-CELL World Drive. The trio of B-Class F-CELL automobiles left Stuttgart on January 30th, along with an entourage of support vehicles. After traversing a variety of highways, city streets and even some unpaved country roads, they crossed the finish line in front of Stuttgart’s Mercedes-Benz Museum this Wednesday (June 1st).  Read More

Hydrogen generated from sunlight and ethanol

An international team of scientists has announced success in creating hydrogen at ambient temperature and pressure using a combination of sunlight and ethanol. The team of researchers from Spain’s Universitat Politècnica de Catalunya, Scotland’s University of Aberdeen and New Zealand’s University of Auckland say the method is potentially cheaper, produces higher yields and, because no high temperatures or pressures are required, uses less energy than conventional methods.  Read More

With up to 80 percent of the weight of a soldier’s gear attributable to batteries, the U.S. Army is obviously interested in replacement technologies that deliver a reliable, reusable power source. Chemical Engineering students at Stevens Institute of Technology in New Jersey believe their invention of a microreactor that can convert everyday fossil fuels such as butane and propane into pure hydrogen for fuel cell batteries might be the answer.  Read More

Hydrogen is certainly one of the big candidates when it comes to finding cleaner fuels to replace petroleum. While it only produces water when burnt as fuel, the process of obtaining hydrogen from natural gas is not quite so eco-friendly – it consumes a lot of energy, and creates carbon dioxide. Now a new process being developed at the Netherlands' Eindhoven University of Technology (TU/e) promises a much more efficient, innocuous alternative.  Read More
