Finding a way to produce hydrogen simply and cleanly would go a long way toward eventual use of the gas as a fuel source. And that's exactly what researchers at the University of Cambridge (UC) have done, adding to a host of other green possibilities that have been proposed for creating the gas.

Algae is proving to be pretty darn useful – in recent years, it’s been used to produce oxygen, purify wastewater, provide light and serve as a source of biofuel. Now, bioplastics firm Algix and clean tech company Effekt are making flexible foam out of the stuff, too.

Researchers at the KU Leuven Centre for Surface Chemistry and Catalysis in Belgium have developed a Polylactic acid (PLA) production technique that is cheaper and greener and makes the bioplastic a more attractive alternative to petroleum-based plastics.
