Scientists use the principle of photosynthesis to develop new methods of hydrogen production

Beijing time, May 30, according to foreign media reports, scientists have developed a new method of manufacturing hydrogen using the principle of photosynthesis. This major breakthrough provides a potential solution to the global energy problem.

These researchers claim that this advanced technology may help tap the potential of hydrogen as a clean, cheap, and reliable energy source. Unlike fossil fuels, hydrogen does not produce emissions when it is burned to make energy. In addition, it is the most abundant element on earth. Decompose water to produce hydrogen and oxygen. Scientists have been working tirelessly for decades to find new ways to extract these elements at different times. This method is not only more effective, but also reduces the risk of explosion.

Scientists at the University of Glasgow in the UK published a paper published in the journal Nature-Chemistry on the 15th, which outlined how they reproduced how plants use water to split water molecules into hydrogen and oxygen at different times and in different physical locations. Experts on the 14th heralded the arrival of this "important" discovery, saying it might make hydrogen a more viable source of green energy.

Professor Xile Hu, head of the Inorganic Synthesis and Catalysis Laboratory of the Swiss Federal Institute of Technology in Lausanne, said: "This research provides an important demonstration of the principle of electrolytic separation of hydrogen and oxygen. Only in-depth research can improve this system, energy efficiency, and lifespan. But this research gives us hope for the future and may help us store green energy at a lower cost. "To date, scientists have separated out by electrolysis Hydrogen and oxygen atoms. The principle of electrolysis is to let electricity pass through water without energy consumption and explosion hazard, because hydrogen and oxygen are separated at the same time.

But in the new electrolysis method developed by the University of Glasgow, hydrogen and oxygen are separated from water at different times through what researchers call “electron-coupled proton buffering”. This helps to collect and store hydrogen as electricity passes through water. In this way, only oxygen is released first, and then hydrogen is released at the right time. Pure hydrogen does not occur naturally, so it must be made with energy. This new electrolysis method takes longer, but is safer and consumes less energy per minute, making it easier to rely on the renewable energy required by the current to separate hydrogen.

Dr. Mark Smyth, one of the authors of the research report, said: "The new system we developed is suitable for industrial-scale hydrogen production, which may be cheaper and safer than the current hydrogen production method. Right now, most of the industry produces hydrogen 'S method relies on the improvement of fossil fuels, but if the sun, wind or waves are used to provide power, we can make an almost completely clean energy source. "

Professor Li Cronin, another scientist who participated in the study, said: "The existing natural gas infrastructure that sends natural gas across the country can easily transport hydrogen to designated locations. If it is cheaper and more efficient, The decoupling process uses renewable resources to produce hydrogen, and the entire country can replace hydrogen with methane to make electricity for homes. This will also allow us to significantly reduce the country ’s carbon footprint. "

Green Energy expert Nathan Lewis, a professor of chemistry at the California Institute of Technology, said: "This seems to be a scientific demonstration of concern. It may solve a problem related to water electrolysis. Now water electrolysis is still a very expensive hydrogen production method."
