Hydrogen Fuel Cells Running On Sunflower Oil

tigersaw writes "You've heard about Biodiesel , Greasecars, and Fuel Cells for a while now. At yesterday's meeting of the American Chemical Society, researchers from the University of Leeds in England described a novel approach that combines these ideas in a fuel cell device that employs steam and two separate catalyts to generate hydrogen using sunflower oil. Experimental results show a hydrogen yield of 90 percent, versus 70 percent in other hydrogen fuel cell technologies. 'The sunflower oil used is the same type found on grocery shelves. "We would happily toss our salad with it," says the researcher, who adds that the process can also work with other types of vegetable oils.'"

This could actually be really cool...

The modern Hydrogen economy has to get over a huge hurdle in the wide-scale distribution network of H2.

Distribution for H2 is pathetically inefficient. In order to ship it at an efficient level, they have to compress it into liquid form. That takes up a lot of energy, along with the associated costs of now transporting a very cold liquid (yeah - not very energy efficient either).

If H2 can be made using a novel approach, you can minimize the huge potential transport and distribution costs by setting up a lot of small production facilities (local refineries?).

This could be a pretty big deal.

Centralised Power

It's like an all-electric car... sure it uses no gas but that power has to come from somewhere to begin with. You've only moved the problem to someone else's back yard.

That's the whole point: one problem to solve (at the power plant) instead of many to solve (at the cars). If you run many electric cars from a single power station, then you have:

• one point to filter for emissions (in the case of fossil fuels)
• no car pollution in cities(!)
• an easy upgrade path when you replace your coal plant with biodiesel or solar or fusion or whatever
• possible economies of scale (subject to electrical transmission losses)

...and so on.
