The research team used a small “diamond anvil” pressure cooker to produce hydrogen at remarkable speed. Enclosed between diamonds and within a tiny space about the width of a pencil lead (shown in the center of the right image), scientists applied very high pressure and 200-300 degrees C heat to a mixture of aluminum oxide, water and the mineral olivine.
