US scientists develop sulfur-containing material to make green hydrogen using sunlight
Scientists at the Oregon State University in the U.S. have developed a new class of materials that uses a sulfur-based chemistry to make clean green hydrogen from water using only sunlight. This removes the need for expensive metal-based catalysts, paving the way for lower-cost green hydrogen production in the near future. As the world looks to move away from fossil fuels through the use of solar and wind energy, the shortcomings of the latter are also coming to the fore. While large renewable energy plants are being run in various parts of the world, energy generated through wind and solar energy cannot be used to drive high-power applications. Hydrogen, on the other hand, offers a cleaner way to run high-power applications, since its combustion produces water as a by-product and no carbon emissions. However, conventional hydrogen production relies on methane, which releases carbon into the atmosphere. So, scientists have been looking for greener methods to produce hydrogen. Photocatalysis of water The simplest way to produce hydrogen is it split water using electricity. This process can be green, depending on how the electricity is sourced. Electricity generated at wind and solar power plants is now widely available, but the cost of...
