The problem of rising carbon dioxide emissions can be solved in three ways: the use of alternative energy sources with low-emission or emission-free at all, capture and storage of carbon dioxide (carbon capture and storage - CCS) in special storage facilities jsl (mostly underground), capture and processing ( for example, in fuel and others.).
Researchers at Princeton jsl University say they have developed a technique that combines two of the three ways, by using solar energy to convert carbon dioxide to formic acid.
With the help of electricity produced commercial solar photovoltaic jsl installation and supplied energy company Public Service Electric and Gas (PSE & G), researchers lab chemistry professor Andrew Bocarsly (Andrew Bocarsly) at Princeton University (Princeton), working jsl together with researchers from the company Liquid Light Inc., New Jersey, were able to convert jsl a mixture of carbon dioxide and water in formic acid (HCOOH) in the electrochemical cell.
The electrochemical cell consists of simple parts produced by machining, includes channels for the passage of fluid between the metal plates, and has a size standard lunchbox. In cell material jsl and placed it on the load applied, which increases up until the process is passing the device will not work at the level of the target reaction.
By optimizing the process known as mapping of resistance, the team has made the adjustment of power generated by the solar panel to power cell that can withstand that led to maximize jsl the efficiency of the system.
According to the scientists, they managed to achieve the efficiency of 2% by combining three electrochemical cells. As they say, it's twice as effective than the natural process of photosynthesis takes place in the tissues of plants and the best efficiency for the system to simulate photosynthesis, built by man.
Formic acid found in the venom of ants, currently has a very wide use - as a preservative and antibacterial agent in livestock feed, in the form of a salt of formic acid as a de-icer to runways at airports. And it has the potential to store energy produced jsl within the fuel cell.
This method has something in common with the system of artificial jsl photosynthesis developed by electronics giant - by Panasonic. However, the system of the Japanese corporation, the principle of which is based on the use of hydrogen produced by splitting water using a nitride semiconductor to produce formic acid, has an efficiency of only 0.2%.
