Bad news for Enbridge, TransCanada and all the other companies working to build controversial pipelines across North America: Pipelines spill three times as much oil over comparative distances as rail, the International Energy Agency (IEA) says.
In an oil market outlook released Tuesday, the agency also said Canada’s oil sands will contribute to a North American “oil supply shock” that could fundamentally alter the state of the global energy market.
“Increasing volumes of crude oil transported by rail raise questions of safety,” the IEA said, as quoted at Bloomberg. “Our analysis reveals that compared to pipelines, rail incident rates are higher while the opposite holds for spill rates.”
The IEA found the risk of a rail spill is six times as high as the risk of a pipeline spill, but pipelines simply spill more when they rupture.
The agency looked at eight years of data from the U.S. Department of Transportation, from 2004 to 2012, but noted it did not include a 2013 rail oil spill in Minnesota that leaked more than double what had been spilled in the four years before.

Oil Spills Since The Gulf Disaster
The study backs up research from the American Association of Railroads, released last month, which found that rail transport spills 0.38 gallons of oil per million barrels moved, compared to 0.88 gallons for pipelines.
Oil from the traditional OPEC nations will decline to just 30 per cent of world supply by 2018, while North American production will account for 40 per cent of new supply coming on to the market, the IEA said.
The agency predicted total oil imports to North America would plummet from 5.6 million barrels per day in 2012 to 3.4 million barrels per day in 2018, as the continent shifts to greater use of U.S. and Canadian oil.
“The supply shock created by a surge in North American oil production will be as transformative to the market over the next five years as was the rise of Chinese demand over the last 15,” the IEA said.
The IEA’s assessment of pipeline safety will likely be good news to the ears of the railroad industry, which has played itself up as an alternative to the development of oil pipelines.
Faced with delays and controversies surrounding the Keystone XL and other pipelines, the energy industry is turning to railroads to fill the gap.
CP Rail, which recently reported its best quarterly earnings on record, says it expects to double oil shipments by the end of 2015.
A number of oilsands companies, such as Cenovus, are mulling using rail as a permanent alternative to pipelines.
Last fall, a B.C.-based company floated the idea of replacing the controversial, proposed Northern Gateway pipeline to Canada’s West Coast with a railway. The idea got some tentative support from aboriginal communities.
A recent U.S. State Department report argued building the Keystone XL pipeline would have little impact on the environment, because it assumed railroads would fill the gap.
But cost could prove to be an obstacle. The cost of moving a barrel of oilsands bitumen by pipeline is estimated at around $10, compared to around $15 to $18 for rail, with some estimates as high as $30 a barrel to ship oil by rail.
