“…The cost for the supply of biomass feedstocks (including their intraregional transportation) was taken mainly from Yamamoto et al (2001). Again, the estimated data on fossil and renewable resource availability were dis aggregated into the 70 model regions by using the country-level, state-level, or sitelevel resource availability estimates [e.g., WEC (1998) for coal resources, and Masters et al (1998) andUSGS (2000) for conventional oil and natural gas resources).…”

Using a bottom-up type global energy model, this article explores in detail the potential role of coal over the 21st century and focuses on the prospects for coal gasification-based conversion technologies with CO2 capture and sequestration (CCS) under the CO2 stabilization target of 550 ppm. The results show that even in the CO2-constrained world, coal can remain one of the important primary energy sources throughout the century on the condition that the resulting CO2 is properly captured and sequestered. Coal's competitiveness in such a world would increase with the introduction of CCS, but decrease with the leak rate for CO2 stored underground. For the optimal coal use, a common trend toward producing convenient and clean final energy carriers via gasification is observed. Under the CO2 constraint, coal is increasingly converted via gasification with CCS into electricity and hydrogen, thereby providing CO2-neutral energy carriers and facilitating CO2 capture, which helps China and India develop in a sustainable manner. These findings prove to be robust with respect to the costs of gasification-based conversion technologies and CCS. It is suggested that the establishment of reliable CCS technologies and low-cost gasification-based conversion technologies and their transfer to developing regions would raise the value of coal and provide energy security benefits under the CO2 constraint. However, it is also indicated that large-scale introduction of coal with CCS into leaky reservoirs would cause large CO2 emissions from leaks over the very long term.

“…Based on the empirical case studies cited above, a global economic model of CO 2 sequestration in depleted oil and gas fields and deep coal seams was constructed. The depleted oil and gas model was based on ultimate resource estimates for the largest 155 petroleum provinces that encompass 32,000 known oil and gas fields (Klett et al, 1997;Masters et al, 1998). The model estimates sequestration capacity and costs for each province based on average depth, oil gravity, location, projected capital and operating costs, and oil prices.…”

Three petroleum extraction technologies offer potential for large‐scale, low‐cost, and long‐term sequestration of carbon dioxide. Enhanced oil recovery (EOR) using CO2 injection is a commercially proven process with more than 120 Gt of “value added” CO2 sequestration potential worldwide. Enhanced gas recovery (EGR) using CO2 injection is conceptually feasible but has not yet undergone testing. Depleted natural gas fields offer more than 750 Gt of moderate‐cost CO2 sequestration potential, not including EGR. Enhanced coal‐bed methane (ECBM) recovery using CO2 injection is undergoing pilot testing in the United States, with favorable early results. ECBM could be used to sequester more than 150 Gt of CO2 in coal basins worldwide. Challenges facing large‐scale application of geologic sequestration in hydrocarbon fields include: (1) high capture and processing costs of anthropogenic CO2; (2) inadequate understanding of many petroleum and coal reservoirs, particularly in frontier areas; (3) rigorous monitoring and verification to convince regulators and the public at large that sequestration is secure and long term; (4) achieving recognition and certification from emissions trading systems; and (5) resolving operational conflicts between sequestration and enhanced recovery. These challenges could be overcome by building on existing technologies from the EOR, underground gas storage, and natural CO2 production and transportation industries and by targeted basic and applied R&D.

TX 75083-3836, U.S.A., fax 01-972-952-9435. AbstractNatural gas is an increasingly important source of the world's energy. Estimating future supplies of this valuable commodity is an important economic and strategic endeavor. This paper analyses historical natural gas production trends for the 53 countries that produce virtually all of the world's natural gas. Using a multicyclic Hubbert method, we forecast the world's future supply of natural gas to the year 2050.Our analysis showed that the world ultimate reserves of conventional natural gas will be around 10,000 Tcf, of which about 7,900 Tcf of gas reserves remains to be recovered at the end of 1997. The world production of natural gas is expected to peak by 2014 at a production rate extending from 2012 until 2017 of approximately 99 Tcf/yr. Based on the 1997 world gas production and the results of this study, the world supply of conventional natural gas will continue for 96 years with reserves depletion rate of 1%/yr.In his 1956, and later 1980, predictions of U.S. natural gas production, M. King Hubbert 1-4 used one complete production cycle to forecast production and estimate ultimate recovery of natural gas for the United States. Several authors have shown that Hubbert's model with one production cycle is generally adequate for predicting crude oil production. However, this study shows that, in the case of natural gas production, most countries exhibit two or more Hubbert-type production cycles. These additional cycles apparently result from changing exploration technology, regulations, and economic and/or political events. Using a Hubbert model with a single production cycle did not allow for these factors. We found that most of the 53 countries apparently exhibit multicyclic gas production. To account for additional production cycles we used a modified version of the Hubbert model which is referred to as the "multicyclic Hubbert" model. A nonlinear least-squares regression was used to determine the parameters of the multicyclic model for each country. Exploration data, when available, were used to calibrate country models with production data. We also present a mathematical analysis of the Hubbert model by deriving equations for determining the production rates at inflection points and their time of occurrence on the Hubbert curve. We will demonstrate a graphical technique to verify the results.
