AnnuRevPlantBiol (2011) Evolution of Photosynthesis

AnnuRevPlantBiol (2011) Evolution of Photosynthesis | photosynthesis | Scoop.it

Students sometimes struggle with all the biochemical complexity involved in photosynthesis, and don't always grasp the overarching themes. This terrific article by Hohmann-Marriott and Blankenship beautifully assembles lots of information into a coherent structure.

 

"Understanding the evolutionary constraints imposed on bioenergetic systems is not only an intellectual pursuit but may be a key to unlock our energy future."

London, UK (SPX) Oct 21, 2013 -
How some plant species evolved super-efficient photosynthesis had been a mystery. Now, scientists have identified what steps led to that change.

The best of two worlds: Solar hydrogen production breakthrough

The best of two worlds: Solar hydrogen production breakthrough | photosynthesis | Scoop.it

Using a simple solar cell and a photo anode made of a metal oxide, HZB and TU Delft scientists have successfully stored nearly five percent of solar energy chemically in the form of hydrogen. This is a major feat as the design of the solar cell is much simpler than that of the high-efficiency triple-junction cells based on amorphous silicon or expensive III-V semiconductors that are traditionally used for this purpose.

The photo anode, which is made from the metal oxide bismuth vanadate (BiVO4) to which a small amount of tungsten atoms was added, was sprayed onto a piece of conducting glass and coated with an inexpensive cobalt phosphate catalyst. "Basically, we combined the best of both worlds," explains Prof. Dr. Roel van de Krol, head of the HZB Institute for Solar Fuels: "We start with a chemically stable, low cost metal oxide, add a really good but simple silicon-based thin film solar cell, and – voilà – we've just created a cost-effective, highly stable, and highly efficient solar fuel device."

Thus the experts were able to develop a rather elegant and simple system for using sunlight to split water into hydrogen and oxygen. This process, called artificial photosynthesis, allows solar energy to be stored in the form of hydrogen. The hydrogen can then be used as a fuel either directly or in the form of methane, or it can generate electricity in a fuel cell. One rough estimate shows the potential inherent in this technology: At a solar performance in Germany of roughly 600 Watts per square meter, 100 square meters of this type of system is theoretically capable of storing 3 kilowatt hours of energy in the form of hydrogen in just one single hour of sunshine. This energy could then be available at night or on cloudy days.
