New artificial photosynthesis eats greenhouse gas

Plants make their own food by catching sunlight with their leaves. Scientists try to simulate the same process of photosynthesis to generate clean energy. Solar panels convert sunlight into electricity. They are popular and are becoming more efficient, but they are not nearly as good as live plants in converting sunlight into usable energy.

Solar panels are pretty useless when there is little light, and it is quite difficult to store electricity from solar cells in such a way that not too many seeps away. Many countries are switching to cleaner forms of energy to combat global warming, and scientists are looking for a more stable form of artificial photosynthesis that is comparable to that of plants.

It seems that there is now a lot of progress. American researchers report a technique in which a special catalyst is used to - in theory - make a more stable version of artificial photosynthesis possible.

Artificial photosynthesis involves more than just collecting sunlight. Just like plants, the artificial form should be able to make energy from sunlight, but also have to be able to store that energy. Most attempts have been made with catalysts of several atoms that have not lasted too long.

The American researchers have now made a catalyst that consists of two atoms of the element iridium. That catalyst should continue to work for a long time. Their technology could store the solar energy in chemical compounds, just like natural photosynthesis. In this way the technique could be a solution to the big problem of solar panels, namely that you only have something to do when the sun shines.

The new technique could become a cost-effective energy source. The advantage of artificial photosynthesis over other forms of solar energy is that the process uses carbon dioxide, something that is very pleasant given the quantities of greenhouse gases that we still pump into the atmosphere.
