Shell calls for greater focus on CCS
Efforts to capture and store carbon dioxide created from the burning of fossil fuels could help to reduce emissions of the gas by up to 40 percent, Shell has claimed.
According to Reuters, the global energy company believes that carbon capture and storage (CCS) projects that pump man-made emissions into the earth's crust will become a lucrative business in the future.
Shell's senior advisor for environmental affairs Kimberly Corley told the agency: "CCS is probably the largest source of potential carbon reduction for the next 30 years and a way to deal with 30 to 40 percent of [global] emissions."
Shell is backing the technology to become a key part of its future strategy and has already established seven test CCS projects to store emissions in empty gas and oil reservoirs.
However, Reuters reported that the significant costs associated with CCS deployments could prohibit its future uptake.
It is estimated that CCS projects will cost Shell approximately $2 billion (£1.3 billion) for each million tons of emissions, a bill that could rapidly spiral upwards given that the US alone emits 7 billion tons (6.4 billion tonnes) of CO2 a year.
Shell recently estimated that its new CCS facility at Ketzin, near Berlin in Germany, will inject 60,000 tons (54,500 tonnes) of CO2 into the ground within its first two years of operation - equivalent to the emissions produced by 30,000 cars a year. http://tinyurl.com/og9ebm
