To achieve only the needed carbon emissions, we reduced nuclear generation back to today’s 19 percent level. With nuclear generation backed down, gas burns increased to 9.6 TCF in 2036. In essence, low load growth means CCS and gas alone are sufficient to meet the carbon target. Alternate scenario three Scenario three attempts to evaluate the case in which neither CCS nor nuclear additions are available. In this scenario, assumed load growth is the same 0.8 percent/year used in EPA’s “core scenario,” and renewables are set at 20 percent. Since CCS is eliminated and no additional nuclear units are allowed, meeting the assumed load growth requires gas burns of a stunning 14.6 TCF by 2036. The bad news is that this scenario results in carbon emissions of 2,100 million tons, well in excess of the 1,700 million ton target. The only way to meet the target was to adjust nuclear generation upward to 25 percent. This allowed the gas burn to fall to 12.4 TCF. The upshot of this scenario is that even with the relatively conservative load growth assumed in EPA’s “core scenario” and 20 percent renewables, if no CCS or nuclear units are added, the carbon target cannot be met. Even when we allowed some nuclear power to be added to meet the target, the lack of CCS makes the natural gas burns required astounding high. Note that 14.6 TCF is roughly double today’s use of natural gas to generate 24 THE SOURCE | THE VOICE AND CHOICE OF PUBLIC GAS http://www.riotronics.com http://www.abloyusa.com
