Water splitting to replicate the natural process of photosynthesis, converting sunlight, water and carbon dioxide into carbohydrates and oxygen. Recently, this has been successful in splitting water into hydrogen and oxygen using an artificial compound called Nafion. High-temperature electrolysis (also HTE or steam electrolysis) is a method currently being investigated for the production of hydrogen from water with oxygen as a by-product. Other research includes thermolysis on defective carbon substrates, thus making hydrogen production possible at temperatures just under 1000 °C. The iron oxide cycle is a series of thermochemical processes used to produce hydrogen. The iron oxide cycle consists of two
Carbon dioxide flooding the water acts to sweep the oil towards the production zone. CO flooding is the second most common tertiary recovery technique and is used in facilities around the world. In connection with greenhouse gas emissions and global warming, CO flooding sequesters underground and therefore offsets CO emissions elsewhere. Carbon dioxide flooding Carbon dioxide (CO) flooding is a process whereby carbon dioxide is injected into an oil reservoir in order to increase output when extracting oil. When a reservoir’s pressure is depleted through primary and secondary production, carbon dioxide flooding can be an ideal tertiary recovery method. It is particularly effective
