> Food companies use hydrogen gas to turn unsaturated oils and fats into saturated ones, which give us margarine and butter. Hydrogen is not used in the production of butter > Long-touted as a sustainable fuel, hydrogen fuel produces no emissions as it burns upon reacting with oxygen—no ignition is needed, making it a cleaner and greener fuel source. It is also easier to store, making it more reliable than solar-powered batteries. no ignition is needed? Easier to store?
