My friends and I were discussing the launch of the world's first hydrogen fuel cell train
by Alstom. They took the technology for this from Hydrogenics, which is a developer and manufacturer of hydrogen generation and fuel cell products based on water electrolysis and proton exchange membrane technology. According to them, Hydrogen vehicles have 100% zero emissions. Hydrogen technology will advance in the future to such a point that fuel cells become a viable alternative.
My question is, can't this be implemented in producing residential electricity? The power plants used to produce electricity need energy which is mostly taken from fossil fuels like coal. The burning of the fossil fuels puts a lot of carbon dioxide in the atmosphere which leads to Global Warming. So if hydrogen technology can be implemented in producing the electricity at home, it can lead to a cleaner environment.
Your thoughts on this? Is there are projects going on to implement this?
