Canon's Fuel Cell May Drive Portable Gear 197
RX8 writes "Canon, Inc., has taken the wraps off prototype rechargeable hydrogen fuel cells, the likes of which may one day power digital cameras, media players, and printers. Canon's demonstrated fuel cells win even more points on the environmental front: while companies such as Toshiba, Sanyo, and NEC have also been working on fuel cells (and had been expected to have developed fuel cell-driven notebook computers by now), those efforts are based on DMFC technology which derives hydrogen from methanol, producing small amounts of carbon dioxide (itself a greenhouse gas) in the process. Canon's cells obtain hydrogen from a refillable cartridge with no toxic byproducts."

It can be hard to hear over the clipped-signal of the marketing hype - but I think the jury is still out on the "environmentally friendly" claims.

Here we go again. Someone will say that hydrogen is a power source and then a bunch of pedants will jump on him / her claiming that it's not a power sources it's a power store as it uses more energy to create it. Then there will be an argument over what constitutes a power source. Does that about sum up the discussion?

So anything that helps products run on electricity more effectively is a good thing. Of course, Canon's stuff wasn't running on gasoline to begin with
I haven't been able to access TFA though.

Infact, wind power should be better suited to hydrogen generation than generation of grid electricity. Generating electricity for the grid has problems since wind is unpredictable so you can't have your wind farms match the current demand on the grid. For hydrogen generation this doesn't matter since you can just adjust the amount of hydrogen you generate depending on how much electricity your wind farm is generating and then _store_ the excess hydrogen, which you can then use during the periods when you don't have enough wind to meet demand directly. Storing hydrogen is much less of a problem than storing electricity.
Maybe this is what the future holds for us - use predictable power generation systems (fisson, hydro, tide, fusion and orbital solar arrays) for electricity generation and less predictable (e.g. wind) for hydrogen generation, where the hydrogen can be used in cars and most things that currently contain high capacity batteries such as laptops.

Sure, you can use hydrolysis, but you can also charge a LiPo or other type of battery.

PS. Methanol would be best for portable electronics unless we find a good solid state hydrogen storage method (because compressed hydrogen wouldn't be good for portable electronics). Most of these direct methanol fuel cells only have about 10% methanol/90%water mixtures, so there's lots of room for improvement here.

One year we could have the hydrogen being produced in a coal/oil fired plant, 5 years later nuclear/wind/solar, and even 50 years later with Fusion. But the end user would never notice because all you need to produce the hydrogen is electricity and water.
humans produce CO2, too (Score:3, Insightful)
Greenhouse emissions may kill us all, but I think we have to worry a lot more about the Chinese burning coal than these fuel cells.
We need to keep some perspective here. Afterall humans generate CO2, too.
