Egg whites can help boost the future of clean energy.


Egg whites – they’re not just a cholesterol-free breakfast. A Japanese researchers have found a way to use based on protein found in protein molecule to more effectively generate hydrogen, which scientists closer to produce hydrogen from water instead of using fossil fuels, and increase the possibility of a hydrogen may become clean, carbon-free energy. At present, most of the hydrogen gas is produced through the emission of planetary greenhouse gases.
Osaka city university graduate school of engineering researchers Hiroyasu Tabe said: “hydrogen is a very environmentally friendly energy, but it is still produced by fossil fuels in the process of industrial, and emissions of greenhouse gases is inevitable. “Our method USES solar energy to produce hydrogen instead of fossil fuels.”
Hydrogen is the simplest and most abundant element on earth, but it usually does not exist and must be produced by substances that contain it, such as water and fossil fuels that contain a lot of hydrogen. Developing an efficient way of producing hydrogen from the water alone can point to cheap and clean fuels without producing carbon dioxide and other heat emissions.
Hydrogen in fuel cells USES chemical reactions rather than combustion to produce electricity, producing only water and heat as by-products. It can be used in cars, houses, portable power supplies and many other applications. Therefore, the hydrogen produced by sustainable energy can produce carbon-free fuel.
But the process of extracting hydrogen from water is difficult and complex, and relies on the use of catalysts that control the molecules that move randomly during production. “The transformation of water molecules includes specific and difficult chemical reactions,” says Tabe. “A large amount of energy provided by sunlight and molecular size is essential for efficient catalysis.”
Pure proteins produced by bacteria can perform this function, but making them requires special laboratory equipment, says Tabe. “However, eggs are known as a protein based chemical,” he said. “Our catalyst can produce hydrogen from water, a ubiquitous compound in the world.”
The researchers used lysozyme in egg whites to extract hydrogen from water.
Application of catalyst B

Japanese researchers use solar energy as an energy source, which successfully in the laboratory “in the size of a coffee cup container” made a small amount of hydrogen, “only use the lysozyme – a protein based chemical derived from egg white – a catalyst hydrogen from water. Lysozyme is a small, stable protein that forms crystals and has many tiny pores to capture particles in a nanoscale reaction vessel, “he said.
Nanoscale containers provide a sense of traffic control for interactions between molecules and increase hydrogen production efficiency, “he explained. These crystals have “highly ordered” nanostructures that allow scientists to “manipulate molecular components in the accumulation of crystals,” he said. To analyze and precisely manage the crystals, researchers used rose red, a dye that is often used in eye drops to identify eye damage.
“This traffic control is a new concept for the catalyst for hydrogen production,” Tabe said. “In the near future, many scientists and engineers will turn their attention to solar energy for cleaner fuel production.”
The scientists described their work in a recent study published in the journal Applied Catalysis B. Tabe, points out that almost every science researchers are working to develop renewable energy, and “the chemist can through development to transform and store energy new materials to contribute to the strategy”, he said. “In the future, our basic technologies will unite different disciplines, breaking political, social and economic barriers.”
