Sažetak
In the recent years, the amounts of green house gases have dramatically increased. This situation led to changing in climate conditions. One of the effective ways to reduce these amounts in atmosphere is CO2 capturing from huge spreading sources and injection it into geological formations. Peridotite is a type of rock that reacts with CO2 at higher rate when compared to the other rocks. Since the reaction of CO2 with peridotite is exothermic, the reaction can be self sustaining; therefore, it can reduce overall energy consumption and costs of CO2 emission. There are several factors that have effects on the reaction, in this paper effects such as pressure, temperature, salinity, acidity, and stirring on the rate of reaction are discussed, and using horizontal wells and bilateral drilling in order to increase rate of reaction and increase the amount of storage are recommended.
