Reuters: Statoil, Shell set world's biggest CO2 seabed plan

OSLO (Reuters) – Energy groups Statoil and Shell plan the world's biggest scheme to bury industrial gases beneath the seabed in a $1.2-$1.5 billion project off Norway to raise oil output and curb global warming, the firms said on Wednesday.
It would be the world's first project to use carbon dioxide to boost oil recovery offshore, though the gas has been injected into onshore oilfields in Texas, company officials said.
Norway's Statoil and Anglo-Dutch Shell said the plan, due to start in 2010-12 and including construction of a gas-fired power plant in west Norway, would need “substantial government funding and involvement.”
“If we succeed, this technology can be used at other fields off Norway and internationally,” Statoil Chief Executive Helge Lund told a news conference.
Under the scheme, Statoil would capture CO2 from a huge, 860-megawatt gas-fired power plant to be built at the company's Tjeldbergodden methanol complex in mid-Norway.
The CO2 would then be piped to Shell's Draugen oilfield off Norway — and later also to Statoil's Heidrun field — and injected into subsea reservoirs, to force oil to the surface.
Lund estimated that the plan, which could bury 2-2.5 million tonnes of heat-trapping carbon dioxide a year, would cost 8-10 billion Norwegian crowns ($1.19-$1.49 billion).
Building the power plant alone would cost 4-4.5 billion crowns, and the CO2 capture system and pipeline to the field would cost a similar amount, Lund said.
“And then we have to do much more work over the next year or so to understand the costs and associated revenues connected to increased oil recovery,” Lund told Reuters.
He declined to say how much the government should pay, but said that without support the project would be uneconomical. Many other firms have been put off by high costs of similar CO2 storage projects, which could help slow global warming.
Environment Minister Helen Bjoernoy welcomed the plan as a “showcase for Norway as an environmentally friendly technology nation.” But she did not say how the government would help.
“This is an important milestone for Shell toward our vision for greener fossil fuels with part of the carbon dioxide captured and sequestrated underground,” Chief Executive Jeroen van der Veer said in a statement.
If things go as planned, a final decision to invest could be made by the end of 2008, the power plant started in 2010-2011 and the first CO2 delivered to Draugen in 2011-2012, Lund said.
“We see that both Heidrun and Draugen have reservoir conditions suitable for enhanced oil and gas recovery, but we have to do more work to be precise on that,” Lund told Reuters.
CO2 from burning fossil fuels is the main gas blamed for blanketing the planet and driving up temperatures, threatening more droughts, floods, heatwaves and raising sea levels.
Many other oil companies are also looking at ways to cut carbon emissions. Schemes for capturing and storing at least a million tonnes of CO2 a year are already operating in Canada, Algeria and Statoil's Sleipner field off Norway.
In Texas, about 30 million tonnes a year is injected to help boost oil recovery at onshore fields under schemes that started in the 1970s before climate change was a worry.
Use of natural gas in power plants is welcome in many countries as a cleaner alternative to dirtier coal or oil. But it is controversial in Norway, which generates almost all its electricity at non-polluting hydropower plants.
Norway, the world's number three oil exporter behind Saudi Arabia and Russia, is also running out of rivers to dam and needs to raise electricity output to cover growing demand. The gas-fired plant would help avert a power shortage in the region.

    Many say we will see $3.50/gal this summer. If you factor in Iran, who knows how high it could go. Everyone knows America MUST get off the oil. After September 11, 2001 I expected our President to call on Americans to GET OFF THE OIL. I was expecting a speech like the one JFK gave that motivated us to reach for the moon. As you know, this never happened. Eventually I realized that the only way this is going to happen is for us to do it ourselves. To that end I created this idea and have been trying to make it a reality..
    The EPA is offering a research grant opportunity that I believe is a perfect fit for this idea. I have sent an e-mail to a hand picked list of university professors who have experience with government research projects. I’m looking to form a research team to apply for the EPA grant, conduct a social-economic experiment and surveys to determine to what extent the American public will support it, project the economic potential of WPH, and identify logistical, social and political obstacles as well as opportunities.
    All government grants are awarded based on merit of the proposed research. I believe WPH has merit but your help is needed to verify it. You can help by posting your feedback. Let the professors and the EPA know what you think about WPH. Do you think this idea is worth pursuing? We need to know if Americans will support a plan like this.
    Do you have any ideas to improve the plan?
    Share any and all of your thoughts.
