Assuming that the technology is implemented, what would be the consequences?
None. This emission is environmentally benign. That's the commonly used jargon in the fuel cell industry. This water is recyclable in nature. It goes into the atmosphere, then returns as rain into the ocean, rivers, lakes, etc. No damage to the environment - long term or near term. On another note, for lower temperature fuel cells, the water is given off as a liquid. For higher temperature fuel cells, the exhaust can be used for heat recovery purposes. So it actually serves some engineering purpose.
KeithPAccording to grade school Earth Science that Water Vapor is the biggest Green House gas that is in existencesomething like 90+% of the green house gases is the water vapor. The environmental consequences of the water vapor (to answer the question asked) would be more clouds and rainwhich would be better for the plants and treesand more water for people to drink and irrigate farms so people can survive.
Hydrogen gas cells are particularly high priced and don't final long.? that's a a techniques greater beneficial problem than their effluent. Water vapor is the biggest greenhouse gas (on worry-free) by using weight, yet basically bills for some million/2 the finished greenhouse consequence (frequently interior the tropics, little or no on the poles - that's the reason AGW warms the poles plenty greater beneficial than something of the earth).? additionally, water vapor basically lasts approximately 9 days interior the ambience till now it precipitates out as rain or snow.? including or subtracting water vapor has an quite small impact on climate; the movers and shakers are the flaws whichcontinual the quantity of water which keeps to be, how plenty types extreme clouds vs. low clouds vs. vapor, etc.
Absolutely none, considering the abundance of that molecule and the transitions it under goes on a daily basis. The problem is implementation into a every day life usage. It's a big dollar alternative source of energy that requires a large storage capacity.
Interesting question, after a brief study some time ago here is my understanding: Hydrogen stored in liquid form is used to run the fuel cells. Normal hydrogen gas is about 75% ortho (parallel spins) and 25% para antiparallel spins. The conversion of hydrogen gas to a cryogenic liquid is highly inefficient: The following heats must be removed: specific, latent, and latent ortho-para. The amount of energy used to convert hydrogen gas to the liquid state with reference to the ortho-para conversion alone is about: 6,000,000 J/kg since in the liquid state, the product is nearly 100% para-hydrogen. To further complicate matters this phase of the conversion can take days to complete depending on the specific process. Further energy losses due to storage, delivery, safty issues, etc. result in more overall inefficiency. Currently, I don't know if these issues have been resolved. Put simply, a great deal of energy must used just to fill the darn fuel cell tank. Hence, there may be environmental consequences as a result of the production process while fuel cell operation itself may seem harmless. I think the argument of increased greenhouse water vapor in the atmosphere as a result of global usage of fuel cells doesn't hold water. I'll omit my counter argument. Earth physics is a very complicated matter. I have no idea what would really happen. Many times nature has a way of surprising us despite all our computer models and seemingly plausible theories. More careful study is needed. Take sides if you must that's what lawyers do, but don't be surprised if you get overruled by nature.
