Natural gas plays an important role in the global energy system as an input to power generation, heating, and industry. This article identifies key drivers and uncertainties for natural gas markets in the coming decades. These include the availability of natural gas from conventional and unconventional sources, the role of international trade, and the impact of climate policies. We build on model-based ...

The 2014 Russian–Ukrainian crisis reignited European concerns about natural gas supply security recalling the experiences of 2006 and 2009. However, the European supply situation, regulation and infrastructure have changed, with better diversified import sources, EU member states being better connected and a common regulation on the security of supply has been introduced. Nevertheless, European dependency ...

We investigate the exertion of market power in the global crude oil market over the past years. Recognizing the difficulty of identifying market power in the crude oil market by empirical studies, we propose a numerical partial equilibrium model formulated as a mixed complementarity problem. Our approach allows for strategic behavior in a Nash-Cournot market, a Stackelberg leader-follower game, an ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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, ...
