The End of Cheap Coal? A Techno-Economic Analysis until 2030 Using the COALMOD-World Model

Questions about the future availability of inexpensive coal supplies are rising. In this paper a numerical model is developed to investigate the evolution of the international market for steam coal used for electricity generation. The "COALMOD-World" model is an equilibrium model that computes future trade flows, infrastructure investments and prices until 2030. The model includes the major domestic ...

What about Coal? Interactions between Climate Policies and the Global Steam Coal Market until 2030

Because of economic growth and a strong increase in global energy demand the demand for fossil fuels and therefore also greenhouse gas emissions are increasing, although climate policy should lead to the opposite effect. The coal market is of special relevance as coal is available in many countries and often the first choice to meet energy demand. In this paper we assess possible interactions between ...

The World Gas Model: A Multi-Period Mixed Complementary Model for the Global Natural Gas Market

We provide the description, mathematical formulation and illustrative results of the World Gas Model, a multi-period complementarity model for the global natural gas market with explicit consideration of market power in the upstream market. Market players include producers, traders, pipeline and storage operators, LNG (liquefied natural gas) liquefiers and regasifiers as well as marketers. The model ...

Modeling and Analysis of the International Steam Coal Trade

Coal continues to play an important role in the global energy sector and with the increase in international trade a global market for steam coal has developed. We investigate market structure and recent price developments with a numerical modeling approach and develop two partial equilibrium models, a quantity based model and a model additionally incorporating energy values. We compare two possible ...

Perspectives of the European Natural Gas Markets until 2025

We apply the EMF 23 study design to simulate the effects of the reference case and the scenarios to European natural gas supplies to 2025. We use GASMOD, a strategic several-layer model of European natural gas supply, consisting of upstream natural gas producers, traders in each consuming European country (or region), and final demand. Our model results suggest rather modest changes in the overall ...

Representing GASPEC with the World Gas Model

This paper presents results of simulating a more collusive behavior of a group of natural gas producing and exporting countries, sometimes called GASPEC. We use the World Gas Model, a dynamic, strategic representation of world gas production, trade, and consumption between 2005 and 2030. In particular, we simulate a closer cooperation of the GASPEC countries when exporting pipeline gas and liquefied ...

A Complementarity Model for the European Natural Gas Market

In this paper, we present a detailed and comprehensive complementarity model for computing market equilibrium values in the European natural gas system. Market players include producers and their marketing arms which we call "traders", pipeline and storage operators, marketers, LNG liquefiers, regasifiers, tankers, and three end-use consumption sectors. The economic behavior of producers, traders, ...

A Strategic Model of European Gas Supply (GASMOD)

This paper presents a model of the European natural gas supply, GASMOD, which is structured as a two-stage-game of successive natural gas exports to Europe (upstream market) and wholesale trade within Europe (downstream market) and which explicitly includes infrastructure capacities. We compare three possible market scenarios: Cournot competition in both markets, perfect competition in both markets, ...

The Infrastructure Implications of the Energy Transformation in Europe until 2050: Lessons from the EMF28 Modeling Exercise

This paper summarizes the approaches to and the implications of bottom-up infrastructure modeling in the framework of the EMF28 model comparison "Europe 2050: The Effects of Technology Choices on EU Climate Policy". It includes models covering all the sectors currently under scrutiny by the European Infrastructure Priorities: Electricity, natural gas, and CO2. Results suggest that some infrastructure ...

The World Gas Market in 2030: Development Scenarios Using the World Gas Model

We discuss potential developments of the world natural gas industry through 2030. We use the World Gas Model (WGM), a multi-period strategic representation of the global natural gas sector, between 2005 and 2030. We specify a 'base case' and then analyse the sensitivity of the world natural gas system with scenarios, including various supply scenarios (e.g., emergence of large volumes of unconventional ...
