Analyses of World Supply of Natural Gas with DNE21+ Model
World Trend of Natural Gas Supply Natural gas supply has steadily increased. Source: OECD/IEA, Energy Balances of OECD/Non-OECD Countries
EMF23: World Natural Gas Markets and Trade Will the world gas market become more fully integrated or will markets remain essentially balkanized? What institutions, policies and conditions are needed to alleviate concerns about safety and other delays and allow globalization to occur? How competitive will the US be relative to Europe and Asia? Will gas flow between north and south or between east and west? Is it cheaper to pipe or ship natural gas? http://www.stanford.edu/group/EMF/home/index.htm Focus:
EMF23 Current Status and This Study EMF23 decided simulation cases to study last month. Our model analyses cannot provide the answers to all the questions, but can provide useful answers to many of the questions. This presentation is not necessarily consistent with the EMF23 case studies. The analyses of the simulation cases for the EMF23 are the future work.
Contents Outline of the world energy model, DNE21+ Model assumptions and simulation cases Preliminary analysis results Final remarks Technological options for CO 2 emission reduction World primary energy production Natural gas production by region Primary energy consumption by region Gas balance in US, EU and China Gas exports from Russia to Europe and China
Outline of DNE21+ Model Linear Programming Model (minimizing world energy system cost) Evaluation time period: 2000-2050 (up to 2100) World divided into 77 regions Energy supply side: bottom-up, demand side: top-down Primary energy: coal, oil, natural gas, hydro&geoth., wind, photovoltaics, biomass and nuclear power Final energy demand: solid, liquid, gaseous fuels, and electricity Electricity demand and supply are formulated for 4 time periods: instantaneous peak, peak, intermediate and off-peak periods Interregional trade: coal, crude oil, natural gas, methanol, hydrogen, electricity and CO 2 Existing facility vintages of energy conversion and transportation are explicitly modeled.
Notes for the DNE21+ Results The DNE21+ model enables to treat and analyze complicated systems consistently and quantitatively on certain assumed conditions. DNE21+, which is utilized to analyze and evaluate global warming mitigation options, explores the least-cost global energy system (energy flow, energy facility capacities, etc.) under given assumptions on the final energy demands, the costs of various technologies, etc. for the case of no-CO 2 - constraint (Reference case) and also for the case of CO 2 constraint. For the case of CO 2 constraint, the reduction in the final energy demands that is caused by the rise of energy costs is calculated inside the model and the least-cost energy system that meets the reduced final energy demands is obtained for this case. DNE21+ does NOT consider the energy security.
Model Regions in DNE21+ Model The world is divided into 77 regions.
CO 2 Sequestration Potential into Aquifer Note: The potential was estimated by RITE based on a sedimentary basin map of USGS. The “ideal” potential of aquifer sequestration is shown.
Assumed Transportation Costs Note: The facility costs are assumed in the model, and the costs per energy or CO 2 transportation are decided within the model. The costs of gas, hydrogen and CO 2 by tanker includes these liquefaction costs.
Assumption of Final Energy Demand Population: IPCC SRES B2 (Task Group on Scenarios for Climate Impact Assessment (TGCIA)) Growth rate of GDP per cap: IPCC SRES B2 Growth rate of final energy per GDP for reference case: IPCC SRES B2 Only selected regions
Model Analysis Results Reference Case (No-CO 2 -Constraint) 550 ppmv Stb. Case (IPCC WGI S550) (Full emission trade is assumed.)
Technological Options CO 2 Emission Reduction Technological Options for CO 2 Emission Reduction - 550 ppmv Stb. Case -
World Primary Energy Production Reference Case 550 ppmv Stb. Case Note: 1TWh=0.086/0.33Mtoe is used for primary energy conversion of nuclear, hydro, wind powers and photovoltaics.
Conventional N.Gas Production by Region Reference Case 550 ppmv Stb. Case Note: The divided regions in the figure are aggregated from the 77 model regions. The production shares of Middle East and Russia increase in both cases. The production in US decreases.
Primary Energy Consumption Reference Case 550 ppmv Stb. Case Reference Case US UK 550 ppmv Stb. Case
Primary Energy Consumption (Contd.) Reference Case Japan China 550 ppmv Stb. Case
Gas Balance in US Reference Case 550 ppmv Stb. Case The production of conventional gas decreases. The production of unconventional gas increases from the year 2025. The import share increases until the year 2030 and thereafter decreases.
Gas Balance in EU Reference Case 550 ppmv Stb. Case The total consumption of natural gas in the 550 ppmv stabilization Case is larger than in Reference Case. The share of import in the total supply increases from the year 2010.
Gas Balance in China Reference Case 550 ppmv Stb. Case Natural gas consumptions in China drastically increase in both Reference and the 550 ppmv stabilization cases, but a large reduction of gas consumptions is observed in the the 550 ppmv Case relative to Reference Case after 2040. Almost all the consumptions depend on the import.
Natural Gas Exports in Russia - Reference Case - Russia - China 10 Mtoe/yr (Y2020) 710 Mtoe/yr (Y2050) Russia - Belarus, Ukraine 60 Mtoe/yr (Y2020) 340 Mtoe/yr (Y2050) Belarus, Ukraine - Poland, Czech, Hungary, Romania, etc. 40 Mtoe/yr (Y2020) 220 Mtoe/yr (Y2050) Poland, Czech, Hungary, Romania, etc. - Germany, Austria, etc. 40 Mtoe/yr (Y2020) 170 Mtoe/yr (Y2050) Note: Only the lines from Russia to Europe and China are shown. The values are the capacity of natural gas pipeline.

Final Remarks The importance of natural gas is almost unchanged between no-CO 2 -constraint and 550 ppmv stabilization until the middle of the 21st century. Conventional natural gas production decreases and unconventional gas production increases in US till 2050. Import share of natural gas significantly increases in EU. The gas production shares of Middle East and Russia in the world increase till 2050. Natural gas flow from Russia to China is larger than that to Europe in 2050 in Reference Case, and almost same in the 550 ppmv stabilization Case. The analyses will be conducted under the harmonized simulation cases for the EMF23 study.
