Gulf Cooperation Council countries are burgeoning economies which are highly dependent on hydrocarbons to fuel their needs for economic growth. GCC nations are fully aware of the mounting consequences of increasing levels of CO2 on the environment, mainly attributed to soaring energy demand of domestic and industrial sector. Regional countries are undertaking concrete steps and measures to reduce their carbon footprint through the introduction of renewable energy and energy efficiency measures. Among other options, Carbon Capture and Storage, popularly known as CCS, can be an attractive proposition for GCC nations.
What is CCS
Carbon capture and storage (or carbon capture and sequestration) is the process of capturing waste carbon dioxide from large point sources, such as fossil fuel power plants, transporting it to a storage site, and depositing it where it will not enter the atmosphere, normally an underground geological formation. CCS is a potential means of mitigating the contribution of fossil fuel emissions to global warming and ocean acidification. As at September 2012, the Global CCS Institute identified 75 large-scale integrated projects in its 2012 Global Status of CCS report. 16 of these projects are in operation or in construction capturing around 36 million tonnes of CO2 per annum.
Among notable CCS projects world, In Salah project in Algeria is a fully operational onshore gas field with CO2 injection. CO2 is separated from produced gas and reinjected in the producing hydrocarbon reservoir zones. Since 2004, about 1 Mt/a of CO2 has been captured during natural gas extraction and injected into the Krechba geologic formation at a depth of 1,800m. The Krechba formation is expected to store 17Mt CO2 over the life of the project.
CCS Prospects in GCC
GCC accounts for 0.6% of the global population but ironically contributes 2.4% of the global GHG emissions per capita. GCC countries are among the top-14 per capita emitters of carbon dioxide in the world. The GCC region is witnessing rapid economic growth and massive industrialization which has led to almost 8% growth in power consumption each year. The region is heavily dependent on hydrocarbons combustion for power generation and operation of energy-intensive industries.
There is an urgent need for carbon abatement measures for the industrial sector in Middle East nations as increasing carbon dioxide emissions will have serious repercussions for GCC and adjoining regions. Some of the potential impacts can be rise in sea level, droughts, heat waves, sandstorms, damage to ecosystem, water scarcity and loss of biodiversity. Carbon dioxide emissions reductions can be achieved from point sources such as refineries, power plants, manufacturing industries etc.
At the regional level, GCC nations have both the drivers and environmental gains to adopt the CCS technologies. Some of the GCC countries are already engaged in R&D initiatives, for example, Saudi Arabia has KACST- Technology Innovation Center on Carbon Capture and Sequestration while Saudi Aramco have their own CCS R&D program for CCS. In Qatar there is the Qatar Carbonate and Carbon Storage Research Center while Bahrain has Sitra Carbon Capture System. Recently, Masdar and ADNOC launched Middle East first Joint Venture for carbon capture usage and storage. On a multilateral level, back to 2007, King Abdullah pledged $300 million to finance a research program on the future of energy, environment and climate change. In addition, a sum of $150 million from Qatar, Kuwait and UAE has been allocated to support CCS research.
To sum up, CCS is a viable option to help GCC countries maintain their hydrocarbons-driven economies while enabling low-carbon electricity generation from existing hydrocarbons powerplants.
