UK Energy Firm Claims its Hydrogen-Nanobead-Based Synthetic Gas Can Burn in Your Car with Zero Emissions | Popular Science

Nanotechnology could clean up the hydrogen car's dirty little secret

and this is interesting:

"And here is the dirty little secret: while politicians and the energy industry talk about the clean future of the hydrogen economy, the DOE's Hydrogen Energy Roadmap foresees up to 90% of hydrogen production coming from fossil fuels – coal, gas, oil – the rest mostly from nuclear power plants (why do you think the oil companies are investing hundreds of millions of dollars into hydrogen technology?). In other words: although hydrogen fuel cell cars themselves may emit nothing but water and heat, the process of powering the fuel cells with hydrocarbons will continue the economy's dependence on fossil fuels and leave behind carbon dioxide (sequestered or not), the primary cause of global warming.
