Sunflowers Seed Hydrogen Economy

Heres an interesting bit of news i found today

An experimental generator that turns sunflower oil into hydrogen has been developed that can safely and efficiently produce fuel for everything from automobiles to homes.

They should probably clarify that the CO2 that is formed during the hydrogen extraction is irrelevant since the plant used to produce the seed processes CO2 anyway. It'd make more sense than saying:

When conventional petroleum-based fuels are burned, they form carbon dioxide, a greenhouse gas that contributes to global warming.

Hydrogen, on the other hand, emits only water as exhaust when used in fuel cells, in which it reacts with oxygen to generate electricity.

and then:

Dupont's experimental hydrogen generator, which can fit on a standard lab bench, uses sunflower oil, air and water vapor, as well as two catalysts that serve to store and release oxygen or carbon dioxide while producing hydrogen.

Which seems kind of paradoxial.

Just in case anyone was wondering.
