Hydrogen

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

Mercedes-Benz F-Cell roadshow hits continent number three

Having crossed Europe and North America, the Mercedes-Benz F-Cell roadshow is now in Australia where the green-painted B-Class F-CELL cars are making the long trek from Sydney to Perth. Surrounding the small fleet is an entourage of more than a dozen vehicles including SUVs, Sprinter vans set up as mobile workshops and refuel stations and a semi-trailer laden with striking red full-length cylinders of hydrogen.  Read More

Scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory have created a composite material that they claim can store hydrogen densely and safely, yet that also allows it to be easily accessed for creating electricity. Some materials that are currently used for hydrogen storage have a relatively small capacity, and need to be superheated or supercooled in order to work at peak efficiency. The new material, however, is said not to have either of these limitations.  Read More

Hydrogen has great potential as a clean fuel source for powering our cars and airplanes, but it also poses some big hurdles – in particular, how to store it. Making practical use of hydrogen in gas or liquid form raises difficulties in terms of volume and pressurization – a hydrogen gas tank for a car would need to be around four times larger than current petroleum tanks. Another possible solution is the use of solid state hydrogen and the European Aeronautic Defense and Space Company (EADS), along with the University of Glasgow, hope to boost this approach by developing a new storage system using materials modified at the nanoscale that receive and release the hydrogen at a faster rate.  Read More

Outdoor types who need power for mobile devices away from the grid may find themselves carrying solar chargers or battery packs but, as we reported last year, hydrogen fuel cells offer instant juice benefits and zero degradation. Now, Stockholm's myFC and SiGNa Chemistry have teamed up to launch the PowerTrekk, a pocket-sized, portable charging solution that combines the convenience of a battery pack with the instant power of a hydrogen fuel cell.  Read More

Neutron scattering analysis reveals the lamellar structure of a hydrogen-producing, biohyb...

One of the biggest problems with the move towards a hydrogen economy is currently the production of hydrogen fuel takes a lot of energy, which generally comes from burning fossil fuels. For hydrogen vehicles to make sense, cleaner more efficient hydrogen production methods will need to be developed. One promising approach takes its lead from the natural processes of photosynthesis in order to convert sunlight into hydrogen fuel. The latest breakthrough in this quest comes from Oak Ridge National Laboratory (ORNL) where scientists have taken an important step towards understanding the design principles that promote self-assembly in natural photosynthetic systems.  Read More

Researchers have made a two-fold breakthrough in advancing renewable energies with the development of a light sensitive dye which transfers electrons more efficiently than conventional technologies. The new dyes stand to be used in solar electricity generation and in creating hydrogen fuel, which in the past has proven expensive and energy hungry.  Read More

The prototype solar reactor that directly converts the Sun's rays into fuel

Because conventional photovoltaic panels produce electricity directly from sunlight, the energy they generate must either be used as it is produced or stored – either in batteries or by using the electricity to produce a fuel that acts as a storage medium for the energy. Now U.S. and Swiss researchers have developed a prototype device that directly converts the Sun’s rays into fuels that can be stored, allowing the energy to be used at night or transported to locations where it is needed.  Read More
