Comparative Analysis of Three Different Negative Emission Technologies: BECCS, Absorption and Adsorption of Atmospheric CO2

Negative Emission Technologies (NETs) are generally considered as vital methods for achieving climate goals. To limit the rise in the global average temperature below 2°C, a large number of countries that participated in the Paris agreement was virtually unanimous about the effective collaboration among members for the reduction of CO2 emissions throughout this century. NETs on the ground that can remove carbon dioxide from the atmosphere, provide an active option to achieve this goal. In this contribution, we compare limiting factors, cost, and capacity of three different NETs, including bioenergy with carbon capture and storage (BECCS), absorption and adsorption. Although there are several advantages for capturing CO2, still some constraints regarding the high operational cost of NETs and industrial condition of these technologies as a method of climate change mitigation is not clear. Thereby no single process can be considered as a comprehensive solution. Indeed, any developed technologies, in turn, have a contribution to the reduction of CO2 concentration. Extensive research needs to be done to assess and decrease NETs costs and limitations.
