New process liberates hydrogen and oxygen from water using heat and light

A new process for liberating hydrogen and oxygen from water has been developed, using heat and light as its power sources.

 

Unlike the previous process I posted, this one results in hydrogen, not methane, which is a potent greenhouse gas.

It sounds like it's one of the most simplistic things to do...seperating a molecule lol obviously it's not. What is the yield or effiency of the method on a large scale....and would it be expensive to produce using the method?

 

pure speculation based on information of course...what do you guys think

p.s. Bascule, just got (understood lol) your quote in your sig,,,,I like it *thumbs up*

ah i remember this from a few weeks ago. someone in my group looked into this a s a possible reaction for a conceptual design of a methanol plant(we needed hydrogen and lots of it) turns out it doesn't scale very well(yet) and a medium scale plant(say 1000 tonnes per day) would cost a few trillion and its operating costs would be on a similar scale.

 

its possible with advances in other areas that it could become a viable industrial process but for now it is a lab scale curiosity.
