is the most abundant element in the natural world, but it is almost always combined with other elements, so it has to be isolated. The problem is that 95% of is currently produced using processes that emit CO2 and therefore contribute to , including steam methane reforming and gasification. Water electrolysis separates hydrogen and oxygen atoms without generating any CO2 emissions, but the process is expensive. Researchers are working on other sustainable methods using microorganisms and photoelectrochemical cells.
