Abstract
This paper investigates the preliminary strategies and tools for the
implementation of CO2 air capture and geological storage as a potential
mitigation option in the future climate policy of Iran. It is a method to capture
CO2 directly from air and store it in geological structures based on large-scale
industrial processes to enable the near-permanent sequestration of carbon. The
reason for selecting this approach originates from its capability to mitigate CO2
from all economic sectors with a single technology, while the conventional
capture methods are designed only for mitigation of CO2 from point sources of
the power generation and industrial sectors. In order to facilitate the workflow of
air capture as efficiently as possible, this study suggests some tools and
directions for the selection of potential sectors and the prospective areas for the
final site selection of the air capture units.
Keywords: CO2 mitigation, carbon capture and storage, air capture, Iran.
1 Introduction
As a party to the UNFCCC since 1996 and as a signatory to the Kyoto Protocol
since 2005, Iran is committed to fulfill its obligations for reducing Greenhouse-
Gases (GHGs) emissions into the atmosphere. Iran is defined as a developing
country under the Convention and is not included in Annex I. However among
developing countries, Iran’s CO2 emission is considerable and placed the country
in the 7th place of the world in 2009 [1]. This amount of emissions is increasing
every year with a rather high rate corresponding to 4.7% each year (during 1994
and 2007) due to the increasing energy demands and low energy efficiency [2].
Iran’s per-capita CO2 emission is 6.3 tons per year, which is more than the global
average (4.48 tons in 2006) and its growth rate is higher than population growth
Keywords
CO2 mitigation, carbon capture and storage, air capture, Iran.
