World's first hydrogen-powered train built in China, reports claim
For the hydrogen-powered city train, a hydrogen fuel cell and a supercapacitor were put in place of the old catenary power supply. According to Chinese media, the electrochemical reaction of hydrogen and oxygen produces energy in a hydrogen fuel cell; the only byproduct of the reaction is water; no byproducts of nitrogen or sulfur are produced.

I come bringing good news about hydrogen
The is a techno-optimist blog, and it's time for another techno-optimist post. By now, everyone knows about the importance of solar and wind power. Some people still argue against these technologies, but the brute logic of falling costs has simply overwhelmed the naysayers.

Ultra-light liquid hydrogen tanks promise to make jet fuel obsolete
A revolutionary cryogenic tank design promises to radically boost the range of hydrogen-powered aircraft - to the point where clean, fuel-cell airliners could fly up to four times farther than comparable planes running on today's dirty jet fuel.
