Hydrogen

The latest findings indicate that the Earth's water may not have come from comets (Image E...

The oceans are a mystery in more ways than one, but you might not expect the answers to come from a pack of electronics and a comet. But that's what the European Space Agency (ESA) says about the unmanned Rosetta probe orbiting comet 67P/Churyumov–Gerasimenko. Though 67P is making its first visit to the inner Solar System and won't come closer to the Earth than hundreds of millions of miles, it is throwing new light on one of the fundamental questions in Earth's history: Where did the oceans come from?  Read More

Researchers have achieved a solar energy to hydrogen conversion efficiency of 12.3% using ...

Using solar energy to split water into its component parts, thereby allowing the solar energy to be stored as hydrogen fuel, generally involves one of two methods: using photoelectrochemical cells to directly split the water, or using solar cells to produce electricity to power an electrolyzer that separates the water molecules. One problem associated with the latter method is that it currently relies on rare metals. But now scientists from Ecole Polytechnique Federale de Lausanne (EPFL) in Switzerland have managed to do so using common materials, and have achieved a record solar energy to hydrogen conversion efficiency in the process.  Read More

The Audi A7 Sportback h-tron quattro

One of the biggest tech stories at this year's LA Auto Show was the fuel cell car. Toyota led the way by launching the Mirai, and Volkswagen slid a fuel cell powertrain into the Golf SportWagen. Audi showed a sportier, more luxurious side to fuel cells in the A7 Sportback h-tron quattro. Ingolstadt calls it the "first performance fuel cell vehicle."  Read More

Researchers at the Australian National University are one step closer to creating an artificial photosynthesis system after replicating one of its crucial steps. The development may lead to an abundant source of hydrogen, a cheap and clean fuel that could replace all petroleum products.  Read More

Toyota's Mirai is the result of 20 years of R&D

On the night before its official launch, Toyota President Akio Toyoda announced that the company's fuel cell vehicle (FCV) will be called the "Mirai." The name, which means "future" in Japanese, marks what the car maker sees as a turning point in automotive technology with the development of both a hydrogen-powered vehicle and an expanded hydrogen fueling infrastructure.  Read More

Airbus is helping fund a project examining the potential for hydrogen fuel cells to replac...

With the airline industry's commitment to halve 2005 CO2 emission levels by 2050 prompting Airbus and others to accelerate the development of alternative jet fuels, Airbus is now getting behind a project to examine the potential for using hydrogen fuel cells on commercial airliners – not to power the jet engines, but to replace the Auxiliary Power Units (APUs).  Read More

An illustration shows how the polymer could clean up smokestack emissions – although its r...

Hydrogen may hold promise as an alternative to fossil fuels, but there's still a huge petrol-producing infrastructure in place, and not many service stations offer hydrogen refills yet. That's why some scientists are exploring a bridging technology known as the integrated gasification combined cycle (IGCC) process, for converting fossil fuels into hydrogen. Along with hydrogen, though, carbon dioxide is also a byproduct of the IGCC process, which must be dealt with. Fortunately, scientists from the University of Liverpool have developed a polymer that soaks up that CO2 for use in other applications.  Read More

Researchers are using hydrogen created as a by-product in sodium chlorate production to po...

By-products are common to most industries. Some are harmless, some dangerous and others useless. Others are simply under-utilized. VTT Technical Research Centre of Finland is using hydrogen generated as a by-product of the sodium chlorate production process in its pilot-scale power plant to produce electricity.  Read More

Sandia’s Daniel Dedrick visits a station in Oakland,  California, as part of a study into ...

Hydrogen fueled vehicles, such as Toyota's FCV and Hyundai's Tuscon Fuel Cell, face a chicken or egg predicament: consumers are rightfully hesitant to invest in such vehicles if they don't have a convenient way to refuel them, and energy companies don't want to cough up dollars for costly infrastructure without significant numbers of such vehicles on the road. But a study by researchers at Sandia National Laboratories says that more existing gas stations in California could readily integrate hydrogen fuel than previously thought.  Read More

In preparation for the Square Kilometer Array (SKA) radio telescope project set to start construction in 2018, the CSIRO’s recently unveiled Australia SKA Pathfinder (ASKAP) radio telescope array has been used to demonstrate and prove the technology involved. With the images it has captured so far, it has also shown its ability to operate as a fully-fledged radio telescope in its own right.  Read More
