The Middle East’s first carbon dioxide recovery plant has been opened at the Gulf Petrochemical Industries Company. This is also one of the first in the world to successfully recycle carbon dioxide air emissions. The $55 million facility at the company’s Sitra facility was formally inaugurated by Gulf chairman and adviser to the Prime Minister for oil and industrial affairs Shaikh Isa bin Ali Al Khalifa, in the presence of board members, company officials and guests.

Carbon dioxide is useful for many industrial operations. It can be used as a feedstock if compressed and transported and it can be used in carbonation of beverages. These are useful and productive recycling efforts but the industry using the carbon dioxide must be close by. (more…)

Carbon dioxide air emissions is one of the big issues in global warming debate. However, before you start controlling by putting the carbon in the ground, you first have to put lawyers in a room to argue. After a year that saw billions of dollars spent around a variety of carbon capture and storage pilot projects, the focus in 2010 will shift from press conferences and engineering discussion to court cases and conference tables.

Everyone has an opinion on what is the right thing to do in global warming. Far from just an engineering decision the task of making technology an effective weapon in the fight against climate change will take a lot more than working out funding details and letting the engineers work.

Research conducted by the University of Bristol, and the University of Leeds in the UK have demonstrated that our climate models may be underestimating the effects of CO2 on global temperatures.

In the long term, the Earth’s temperature may be 30-50 per cent more sensitive to atmospheric carbon dioxide

than has previously been estimated, reports a new study published in Nature Geoscience this week.

The results show that components of the Earth’s climate system that vary over long timescales — such as land-ice and vegetation — have an important effect on this temperature sensitivity, but these factors are often neglected in current climate models.

BRUSSELS (Reuters) – Europeans could help cut climate warming emissions to much safer levels for just 2 euros ($3) each per day, but they would also have to cut back on driving and meat eating, a report said Tuesday.

Other long-term changes would include using the train instead of flying for journeys of under 1,000 km, said the report by the Stockholm Environment Institute, commissioned by Friends of the Earth Europe (FOEE).

The study targets a European cut in climate-warming emissions such as carbon dioxide to 40 percent below 1990 levels over the next decade.

“It’s not just about investment, it’s also about lifestyle changes,” said FOEE campaigner Sonja Meister. “This report shows one pathway that would see air travel in the EU cut by 10 percent by 2020 and travel in private cars by 4 percent.”

U.S. researchers have demonstrated a technology that uses the sun’s heat to convert carbon dioxide and water into the building blocks of traditional fuels, a reverse combustion process that may emerge as a practical alternative to sequestration of CO2 emissions from power plants.

The prototype “Sunshine to Petrol” system, developed by Sandia National Laboratories in New Mexico, uses concentrated solar energy to trigger a thermo-chemical reaction in an iron-rich composite located inside a two-sided cylindrical chamber.

The iron oxide is designed to lose an oxygen molecule when exposed to 1,500 degree C heat, and then retrieve an oxygen molecule when it is cooled down, essentially converting an incoming supply of CO2 into an outgoing stream of carbon monoxide.

A study of the accumulation of carbon dioxide in the world’s oceans from 1765 to the present shows that as humanity pumps more CO2 into the atmosphere, the capacity of the world’s oceans to continue absorbing carbon appears to be decreasing.

Researchers from Columbia University and NASA estimate that since 2000, the proportion of fossil-fuel emissions absorbed by the oceans may have declined by as much as 10 percent. In effect, researchers say that industrial activity has been producing so much C02 since 1950 that the oceans are slowly becoming saturated with the gas.

For years now, many members of Congress have insisted that cutting carbon emissions was difficult, if not impossible. It is not. During the two years since 2007, carbon emissions have dropped 9 percent. While part of this drop is from the recession, part of it is also from efficiency gains and from replacing coal with natural gas, wind, solar, and geothermal energy.

The United States has ended a century of rising carbon emissions and has now entered a new energy era, one of declining emissions. Peak carbon is now history. What had appeared to be hopelessly difficult is happening at amazing speed.

For a country where oil and coal use have been growing for more than a century, the fall since 2007 is startling. In 2008, oil use dropped 5 percent, coal 1 percent, and carbon emissions by 3 percent. Estimates for 2009, based on U.S. Department of Energy (DOE) data for the first nine months, show oil use down by another 5 percent. Coal is set to fall by 10 percent. Carbon emissions from burning all fossil fuels dropped 9 percent over the two years.

The University of Bristol in the UK has published a study based not on climate modeling, but on statistical analysis of data including historical data from Antarctic ice cores.

The study shows that the balance between the airborne and the absorbed fraction of carbon dioxide has stayed approximately constant since 1850, despite emissions of carbon dioxide having risen from about 2 billion tons a year in 1850 to 35 billion tons a year now. This suggests that terrestrial ecosystems and the oceans have a much greater capacity to absorb CO2 than had been previously expected.

The U.K.’s Institute of Mechanical Engineers has proposed three geo-engineering schemes officials say could be immediately implemented to slow global warming: building artificial trees that absorb large amounts of carbon dioxide, using algae tubes to pull CO2 from the atmosphere, and painting the roofs of buildings white.

The engineers said that these three ideas, if carried out on a wide scale, could absorb much of the CO2 produced annually in the U.K. and cool temperatures.

The engineers shied away from more ambitious geo-engineering proposals — such as seeding the oceans with iron to encourage the growth of CO2-absorbing plankton — and focused instead on practical solutions that could be carried out soon.

Despite a global recession, carbon dioxide emissions rose by 1.94 percent in 2008 to 31.5 billion tons, the 10th straight year of significant increases, according to the German renewable energy institute, IWR.

The institute calculated the increase using official government figures, noting that CO2 emissions have risen by 40 percent since 1990 — the year against which emissions reductions were to be measured for the 1997 Kyoto Protocol limiting greenhouse gases.
