British scientists attempt to simulate photosynthesis to produce zero-carbon fuels
British scientists are exploring how to simulate photosynthesis in plants, converting sunlight into energy and producing hydrogen as car fuel. Hydrogen is a zero-emission fuel that can be used in cars or converted into electricity. As countries around the world seek to reduce greenhouse gas emissions from fossil fuels, these scientists will collaborate with other researchers globally to investigate the possibilities of artificial photosynthesis. Julea Butt, the lead researcher at the University of East Anglia, explains, “We will simulate photosynthesis by placing miniature solar panels on microorganisms.” The £800,000 (US$1.3 million) research project will be conducted by scientists from institutions including the University of East Anglia, the University of Cambridge, and the University of Leeds. Scientists believe that simulating photosynthesis can utilize solar energy more efficiently than current solar converters. Many countries are currently developing at least one renewable energy source, such as solar, wind, biofuels, or a combination of multiple energy sources, to determine which renewable energy source is most competitive. Due to the continued rise in global carbon dioxide emissions, some experts believe that more extreme methods are needed to curb rising global temperatures. Some of these extreme methods are quite controversial, such as removing large amounts of carbon dioxide from the atmosphere and using artificial clouds or space mirrors to block sunlight.
