'''Artificial photosynthesis''' is a research field that attempts to replicate the natural process of [[photosynthesis]], converting [[sunlight]], [[water]] and [[carbon dioxide]] into [[carbohydrates]] and [[oxygen]]. Sometimes [[Water splitting|splitting water]] into [[hydrogen]] and [[oxygen]] by using [[sunlight]] [[energy]] is also referred to as ''artificial photosynthesis''.
Research is being done into a streamlined form of photosynthesis which breaks water into oxygen and hydrogen [http://www.rps.psu.edu/0009/energy.html] . This process is the first stage of plant photosynthesis (the [[Light-dependent reaction]]). Carbon dioxide is not required in this approach. The hydrogen released in artificial photosynthesis (stage 1) could be used in hydrogen engines to generate "clean" energy.
The [[light-independent reaction]] (aka the [[Calvin-Benson cycle]]) is the second stage of plant photosynthesis, which converts carbon dioxide into glucose. Glucose is stored energy for a plants' growth and repair. It has been suggested that such a process replicated on an [[industry|industrial scale]] could help to counter [[global warming]]. Specifically, the [[light-independent reaction]] of photosynthesis could be used to "mop up" excessive amounts of carbon dioxide in the atmosphere. [http://www.futurehi.net/archives/000159.html] Again, however, such a process would ultimately require a source of energy, just as plant photosynthesis does.
