3-14 MWe = th Qrec 1MJ/1000kJ 1/t (3-3) where Qrec = recoverable thermal energy (heat) in kWs (or kJ) th = net cycle thermal efficiency (fraction) t=secondsin30years=30yrx365days/yrx24hrs/dayx3600s/hr.=9.46x108 s Specifying a recovery factor is arbitrary – however, by assuming a range that spans an order of magnitude and is always lower than the estimates by Sanyal and Butler, we have sufficiently captured the inherent uncertainty in this prediction. The exploitable amount of thermal energy was further reduced by assuming that only a small fraction is actually removed during the period of production to generate electric power. This additional reduction was implemented by specifying a mean temperature of the reservoir at the end of production. This is the abandonment temperature [Tr,a in Eq. (3-1)] and had a value of 10°C below the initial rock temperature, Tr,i. Table 3.2 shows the recoverable heat as electric power for the United States, assuming a 30-year project life for each depth and average temperature, and a 20% recovery factor. Table 3.3 shows the recoverable heat as electric power using a 2% recovery factor. At only 2% recovery, we note that the 4-5 km deep section of the EGS resource on its own represents an increase of about a factor of 25 over today’s U.S. electricity production from geothermal energy. As we go deeper, or increase the recovery factor above 2%, the recoverable electrical power increases proportionally. Going forward, we expect both enhancements to occur as a result of EGS technology improvements from invested R&D and learning curve cost reductions (see Chapter 9 for more details).
