RoseStreet Claims Hydrogen Breakthrough With Thin Film Solar Cell

September 14, 2009

RoseStreet Labs Energy claims a hydrogen milestone: the ability to generate hydrogen gas from sunlight using solar cells and no external energy.

The Phoenix company offered little detail about its achievement or the volume of hydrogen gas it observed. And two officials at Rosestreet, when contacted, declined to elaborate.

Nonetheless, if true, the development could be promising since up to now generating hydrogen has consumed significant energy. In a press release the company said the hydrogen was generated without external power or the use of petroleum products, such as natural gas.

Rosestreet said its thin-film cells, based primarily on nitride technology, are expected to begin commercial field trials in 2010 and achieve 25 percent or greater efficiencies. Still, its pace of development has been slow.

The company licensed photovoltaic technology from the Lawrence Berkeley National Laboratory and Cornell University in 2005 and vowed then the technology could achieve astronomical efficiency above 48 percent. A year earlier, it had purchased a wafer bumping plant from Kulicke and Soffa Industries.

While the prospect of generating hydrogen without an external power source is exciting, Rosestreet’s unwillingness to discuss the accomplishment even at a high level is suspicious. Perhaps this message on the company Web site best explains its goals: Rosestreet is seeking investment funding.


Electric And Fuel Cell Car Odyssey Goes On With New Models From Daimler, Tesla And Nissan At Starting Line

September 2, 2009

More eco cars are headed to the market with Daimler’s Mercedes unveiling a fuel-cell vehicle, Nissan polishing an electric model and Tesla expected to announce a joint design.

Daimler’s Mercedes said it will begin shipping a hydrogen fuel-cell vehicle – referred to as the B-class F-cell – in Europe and the United States next year. Two hundred of the cars are to be built by the end of the year and will make use of a high-torque electric motor.

Mercedes claims the B-class F-cell has a range of 250 miles on a tank of hydrogen and starts well in cold weather, a long-standing drawback with hydrogen vehicles.

Nissan is targeting the mainstream market with its LEAF, an electric vehicle with a 100-mile range. The family-oriented vehicle seats five, runs on lithium-ion batteries and its expected in 2011. It has a top speed of 90 mph.

As to its price, Nissan says, “we’re unable to give an exact price, but we’re targeting a price in the range of other typical family sedans.”

Tesla CEO Elon Musk referred obliquely to a car Tesla and Daimler are jointly designing in a blog post this June. The vehicle is expected to be announced this year and “like the Smart EV…will also be an electric car that almost anyone can afford.”

Tesla has already said it is supplying Daimler with battery technology for 1,000 compact Smart EVs, and Daimler is providing engineering and production support for Tesla’s Model S, a $50,000 sedan expected in 2011. Daimler took a 10 percent stake in Telsa in May.


Hydrogen Power Breakthroughs Continue

August 25, 2009

Developments in the hydrogen power industry are moving at a fast pace.

Earlier this month, Blacklight Power, working with scientists at Rowen University in New Jersey, announced it was able to generate more energy from hydrogen than the process of mining hydrogen from water consumes. The breakthrough has tremendous potential since the opposite has always been true, a drawback that has constrained hydrogen’s potential as a pollution free fuel for cars, airplanes and power plants.

Now Blacklight competitor Chava Energy of Sebastopol, CA, is claiming an equally impressive feat. The company claims it is running a motor partly on what it calls “fractional hydrogen,” a key step in the quest for a fossil-fuel-free internal combustion engine.

“The evidence so far is encouraging,” says co-founder Mark Goldes. “We believe it is true.”

Fractional hydrogen is a compressed version of the hydrogen atom and it creates enough kinetic energy to push a piston or drive electrons through copper wire.

Goldes said the company passed the milestone earlier this year. If true, “it changes the whole ball game,” he said. “It clearly has some very significant implications.”

One implication is an automobile that runs without fuel. Just add a gallon of water every 1,000 miles or so and rely solely on hydrogen. Another is a self-contained power plant without a belching smoke stack.

Goldes declines to discuss the scientific details behind his process. But he estimates he will be able to market a fuel cell in a year and a vehicle motor in two years. The motor will sell at a price competitive with internal combustion motors, he says.

Size is not expected to be an issue. The first MagGen (stands for magnetic generator) will be a box about 12 inches in length and five inches high and wide. Two will have the juice of a 120-volt socket – initially making them appropriate for charging an electric car and ending the need to plug it in at night. Performance is expected to improve and size will shrink.

Goldes says he has begun to seek new funding to accelerate his push to the market. He is shying away from venture money and leaning towards more friends and family money. But, it might make sense for him to rethink that stance. First to market advantage is crucial even if you own a little bit less of your company.


Breakthrough With Hydrogen Power And An Undiscovered Molecule Too

August 17, 2009

Hydrogen has long been seen as the energy source of the future. Non-polluting, abundant, it could be the ideal fuel for cars, airplanes, even large power plants.

The one hurdle is that separating hydrogen from water requires more energy than the energy generated when hydrogen is consumed as a fuel.

This could be changing. According to BlackLight Power of Cranbury, N.J., scientists at Rowen University found a way to generate more energy than it takes to create hydrogen and produced a previously undiscovered hydrino in the process.

“The energy released forming a hydrino is over 200 times the energy required to extract hydrogen from water by electrolysis to produce the new hydrogen fuel consumed,” says a BlackLight release.  The company has developed a solid-chemical fuel as a catalyst for the reaction.

A hydrino is a low-energy form of hydrogen.

The results appear to be step toward large-scale commercialization of hydrogen fuel. A paper discussing the work is published in the Central European Journal of Physics.
