Recent research compiled by Eoin Finn shows that it is time to reconsider an
essential aspect of the proposed LNG industry - how the LNG plants would be cooled.
“Seawater is not just water. It is actually a community of living organisms, some of which spend
their whole lives in that water. They… produce eggs and larvae that grow up in that water.”
Using seawater to cool LNG plants is akin to running those organisms through a heated blender. Why is this a concern? A large LNG plant would use 70,000,000 - 270,000,000 litres of seawater per hour. If this was freshwater, that would be equivalent to between 14 percent and 55 percent of the daily, residential Canadian water use, for each large LNG plant. Eighteen plants are proposed.
Shell's LNG Canada plant at Kitimat proposes to use freshwater from the Kitimat River to accomplish the cooling.
It may be out of sight, but seawater cooling is no longer out of mind.
This one aspect of the proposed LNG industry would have monumental impacts on riverine and marine ecosystems,
especially on salmon ecology. Read the full report here.
