Fuel Cell

The Stanford University water splitter could save hydrogen producers billions of dollars (...

A new emissions-free device created by scientists at Stanford University uses an ordinary 1.5-volt battery to split water into hydrogen and oxygen at room temperature, potentially providing a low-cost method to power fuel cells in zero-emissions vehicles and buildings.  Read More

The proposals are intended to produce new power sources, such as the fuel cell used in thi...

Once upon a time, energy systems for space missions were simple. You used batteries for very short missions, solar panels in the inner Solar System, nuclear power generators if you were beyond Mars or needed a lot of power, and fuel cells for manned spacecraft. However, as space exploration starts looking into lunar polar craters, comets, and the icy moons of Jupiter, new energy systems will be needed. To anticipate that need, NASA has made awards to four proposals to develop advanced energy storage technology for future manned and unmanned space missions..  Read More

The PowerTrekk 2.0 is designed to charge more power-hungry gadgets such as tablets

After introducing its PowerTrekk portable fuel cell charger several years ago, Swedish company myFC is readying the 2.0 version. The new model is close to three times more powerful than the original, offering enough juice to charge tablets, along with smaller devices like smartphones and GPS units.  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

The USC organic redux flow battery (not pictured) replaces metals with water-soluble organ...

Lithium-ion batteries have made portable, rechargeable electronics commonplace. Unfortunately, they do have some glaring drawbacks, including heat issues, being made with rare, toxic elements, and the fact the technology doesn't scale up very well, which limits applications. A team of scientists at the University of Southern California (USC) is working on an alternative in the form of a water-based organic battery that is not only cheaper and more environmentally friendly, but also holds the potential for scaling up for use in wind and solar power plants as a means to store large amounts of energy.  Read More

The Tucson Fuel Cell is available in the US for a US$499/month lease

The hydrogen economy sounds great, and has ever since it was first proposed in the 1970s. The tricky bit is how to get there, because without the necessary infrastructure, a fuel cell car that runs on hydrogen is little more than a conversation piece. As Hyundai delivers its first Tucson Fuel Cell CUV to its new lessee, Timothy Bush, the South Korean carmaker unveiled its plan to jump-start the hydrogen car economy by giving the fuel away to its customers.  Read More

The cell stacks that are the heart of a home fuel cell system being developed by Fraunhofe...

As the world shifts to alternative forms of energy, ways to make homes less dependent on the grid continue to gather steam. Fuel cells, which are more efficient and have lower emissions than internal combustion engines seem like a logical candidate for taking up the slack, so the Fraunhofer Institute for Ceramic Technologies and Systems (IKTS) in Dresden is partnering with the heater manufacturer Vaillant to develop a domestic fuel cell system that uses natural gas to produce both heating and electricity.  Read More

Carbon monoxide gas could be a new main source of ethanol fuel (Photo: Shutterstock)

Ethanol may be touted as a more eco-friendly alternative to fossil fuels, but it's not without its own drawbacks. Most importantly, the corn or other plants required as feedstock often take up field space that could otherwise be put to use growing food crops. Also, as with other plants, the feedstock crops require large amounts of water and fertilizer. Now, however, scientists at Stanford University have devised a method of producing liquid ethanol from carbon monoxide gas.  Read More

New green designs at the 2014 Geneva Motor Show

In addition to the sporty and strange, the Geneva Motor Show hosts its fair share of green cars and concepts. This year, everyone from mainstream manufacturers to university teams showed designs built from ultralight components, powered by alternative fuels and otherwise designed around fuel- and emissions-frugal commuting.  Read More
