Looks like there are still some minor hurdles to overcome though:
The researchers heated olivine minerals in water to a couple of hundred degrees Celsius, and added a little bit of ruby (aluminium oxide) to the mix to provide a source of aluminium atoms. The whole mix was placed into a miniature pressure cooker, formed of two diamonds, that squeezed the mixture to 2,000 atmospheres pressure.

"If you were to process around 10% of the current hydrogen production by this method it would require a volume of rock similar to that used for cement production today," said Dr Daniel.
The new method uses much lower temperatures and involves no fossil fuel. This type of "green chemistry" promises a route to new sources of carbon-free energy at low environmental cost.
How do they heat the water to several hundred degrees? How the *** do they think extracting a similar amount of rock to that used in cement production would be powered? Carbon free energy!! Are journalists all thick?
