(Phys.org)—The prospect of creating clean, renewable hydrogen fuel is closer than ever after a breakthrough in our understanding of photosynthesis.

Professors Rob Stranger and Ron Pace from the Research School of Chemistry in the ANU College of Physical and Mathematical Sciences used computer modelling to reveal the molecular structure of the photosynthesis reaction site in plants. This is where sunlight is used to convert water into its components – hydrogen and oxygen.

For the first time, they have identified the specific in a plant's photosystem that are converted into oxygen.

Their results, published in , are important for the insight they offer into how we could develop an alternative fuel source from water by mimicking the natural photosynthetic process.

"The part of the plant's photosystem that is important to this process is called the oxygen-evolving-complex (OEC)," said Professor Stranger.

"If we can steal nature's secrets and understand how the OEC performs its chemistry, then we can learn to make hydrogen much more efficiently. And hydrogen is the fuel for a totally future."

Professor Pace said that while scientists know the OEC contains four and a calcium atom, they have been trying for decades to determine the exact structure of the system and how it works.

"Our work confirms the OEC structure and means researchers can progress new fuel developments based on photosynthesis."

The 'process' is not being 'Stolen' from Nature . . . It is simply 'being understood'! Keep up Your good work, H2 is the only solution for the diminution of our massive C02 mess. I am not convinced that it is all man's fault, but we have done the planet no better; what with 'overfishing ad infinitum' . . .we have not even progressed beyond destroying rare species for just a few of their parts! Using those 'parts' for dubiously successful objectives!
