However, estimates of economically recoverable oil from underground injection of carbon dioxide for enhanced oil recovery (CO 2 EOR) are in the range of 35 to 50 billion barrels of oil (BBO), suggesting that larger volumes of. Thus, the 65 million MT of new CO 2 used for EOR today represents only about 3% of coal plant emissions.
Although market-based mechanisms need to be implemented soon to establish a framework for emissions reductions, the Carnegie Mellon University (CMU) team argues, the range of prices for CO 2 currently under discussion will be too low to enable achieving the longer-term targets. Samaras et al. The same is true of natural gas-fired plants.
Geologic storage is currently focused on five types of formations:(1) depleted oil and gas reservoirs, (2) deep saline formations, (3) unmineable coal seams, (4) oil- and gas-rich organic shales, and (5) basalts. It will also improve wellbore characterization, including the bonds between casing, cement and formation.
However, many of these studies rely on a single electricity production emission factor estimate or conduct sensitivity analyses on grid emission factors over a range of power plant types. They also assumed lifetime vehicle miles traveled ranging from 100k to 150k miles with a best estimate of 125k miles used for the base case analysis.
Today the average efficiency of the US fleet of steam Rankine cycle power plants is in the lower 30% range.

These emissions add an average of 50–70 g CO 2 per megajoule of biofuel (range 30–90) and are insensitive to the fraction of residue removed. The lignin fraction of residue can also potentially be burned to produce electricity, off-setting coal- generated electricity and saving emissions of up to ?55g g CO 2 e MJ ?1 55g CO 2 e MJ ?1.
The cycle is operated above the critical point of CO 2 so that it does not change phases (from liquid to gas), but rather undergoes drastic density changes over small ranges of temperature and pressure. This allows a large amount of energy to be extracted at high temperature from equipment that is relatively small in size.
