  1. This proposal will take more than just a few TRILLION dollars to even get an operational plant running, all for what?it certainly doesn’t affect the climate at all!

  2. I’ve evaluated a half dozen of these Carbon Sequestration projects and have never found the availability of storage volume to be the limiting factor. Generally when you look at taking CO2 at a slight vacuum up to several thousand psi the cost of compression is staggering. Small amounts of water vapor have a tendency to create a very corrosive environment in high pressure CO2 (regardless of whether you are transporting it as a liquid, gas, or dense phase). The cost of materials for high pressure, low temperature, corrosive fluids tends to be really high. I can put CO2 into any coal seam in the world, but at the end of the day spending billions of dollars to hide plant food has had pretty bad economics.
