Coleman To Sell Portable Fuel Cell Generator
HobbySpacer writes "
Popular Science reports that
Coleman Powermate
will soon start selling a small portable fuel cell power supply.
The AirGen Fuel Cell Generator provides 1.2kW for up to 10 hours
on a bottle of pure hydrogen. Interestingly, the company had to
set up its own distribution system to insure it could deliver a
refill anyplace in the US within 2 days. The unit, built by
Ballard, goes for a pricey $8k but perhaps worth it if an indoor emergency backup is needed. Fuel cells can also be found for sale at the
Fuel Cell Store and Greenvolt.
Perhaps the hydrogen economy is closer than most people thought."
Although, fuel cells are a door into a world of cleaner, more abundant energy, it must be said that with every great inovation and evolution in technology comes with an even greater responsibility. If the hydrogen economy is here, then we have to consider where that hydrogen is coming from. Is it going to come from hydrocarbons like oil? Is all that hydrogen going to be generated from the electrolysis of water? Are we going to use bimass? If its oil, then we may be in just as bad a situation. The refinement of oil leaves a tremendouos number of nasty by products, not to mention our continued dependance on a non-renewable resource. If we get it from water, then what generates t he electricity? Solar and wind are options, but will require tremendous investement to fulfill the requirements to generate the amount of hydrogen necessary to replace the internal combustion engine. If its biomass, I havent seen the numbers to indicate the amount of byproducts to make harvesting economical, although I know it had been done on a limited scale. There is a give and a take. There are no free lunches. I want to know if we are going to decrease the amount of pollution we are dumping into the environment, or make the situation worse. Fuel cells, and hydrogen power in general, have proved themselves efficient and clean on a small scale, but untested on a large scale. I still see the same unanswered questions of production, distribution, maintenance and disposal.
Hydrogen is not a primary source of energy. It's an energy transmission and storage system. As such, It has a lot of potential advantages over the current options -- long-distance power cables, tanks of gasoline, batteries, etc. but you still have to get energy from somewhere else to make it. The portability element makes some power generation options (off-shore wind and wave, desert solar, hydroelectric) more economic than they are at present when you have to build power lines, but oil and coal are not instantly obsolete.
