Some automakers want to get serious about bringing hydrogen-powered fuel cell vehicles to market if a big wall can be climbed – the one that puts the cost of H2 vehicles out of reach for some OEMs and at least $50,000 for others. That number could slide down thanks to researchers from South Korea, Case Western University and University of North Texas who have discovered an inexpensive and easily produced catalyst that could replace pricey platinum, the catalyst for the required oxygen-redu

People looking to maintain their health have long been advised to take their minerals. Will trucks be doing the same thing?

Ford has officially served up the details on the upcoming 2013 F-Series Super Duty. Buyers will be able to snap up the latest work rig with in a new Platinum trim level that throws in niceties like SYNC, MyFord Touch, navigation and a rear-view camera as standard equipment. Power telescoping mirrors are also part of the package.

Nissan makes a whole mess of different crossovers, and not just the ones we get here in North America. Overseas, the Japanese automaker has even more, like the Qashqai, the Koleos (sold by sister-company Renault) and the vehicle you see here, the X-Trail.

With over 20,000 Leafs running around the planet, Nissan is looking to introduce yet another alt-powered vehicle to the world, and judging by its recent work with fuel cells, a hydrogen-powered vehicle could be here in four year's time.

The UK's first public-access hydrogen fueling station – the one opened by Honda just days ago – dispenses hydrogen at 350 bar (5,076 psi) and 700 bar (10,153 psi). The reason is that these are the two standard filling pressures adopted by the world's major automakers, and it requires a lot of technological work to keep the H2 in a tank that pressurized. But what if 500 psi becomes the standard?

Efficiency is a large stumbling block if you're looking for a way to replace gasoline. It's pretty hard to better such an exceptional fuel, and several alternatives show promise but are nagged by inefficiencies or cost, and usually both. Nanotech to the rescue; it may soon be possible to produce your own hydrogen at home cheaply and easily, and NiMH batteries and fuel cells also stand to become less expensive and offer much better performance. With claims like that, QuantumSphere might well be s

I don't know nearly enough about the mining of precious metals such as platinum to estimate how much it costs to get a reasonable amount from the earth. But, I do know that the metal is expensive to buy, so it must at least be reasonably difficult, right? So, perhaps we should be looking at recovering the precious metals, again like platinum, that we have already unearthed. That is what researchers from Cardiff University are suggesting.

When I first heard about this type of theft a couple months ago, I thought it was an isolated incident. But in the last month I've found reports from Florida, Louisana, Tennessee and Michigan of similar actions: thieves are cutting out the catalytic converters on late-model vehicles to get at the platinum and rhodium. Likely victims are fullsize SUVs or trucks because of the higher ground clearance, giving the thief plenty of room to crawl under with a hacksaw. The irony is that there may be onl

Yesterday, PhysOrg reported on the recently published fuel cell research of two Los Alamos scientists, Rajesh Bashyam and Piotr Zelenay, in the scientific journal Nature. Searching for a low-cost alternative to platinum, the duo developed a composite consisting of cobalt, polymer and carbon. The new catalysts weren't able to produce as much electrical energy as its platinum-based counterpart, however, the composite exhibited "exceptional performance stability" during a 100-hour test session.

The catalyst found in most fuel cells is composed of platinum, but Dr. Fraser Armstrong, a chemistry professor at Oxford University, believes that enzymes known as hydrogenases may hold the key to efficiently unlock the power of hydrogen.
