The regional natural gas markets are expected to gradually become more integrated. The major driving forces are lower LNG costs, more spot trade, and increased need for imports into the US and other key markets. In this paper we examine various scenarios for a future global gas market,...

Reduced transportation costs are usually associated with lower import prices, increased trade and price convergence. In this paper we show that the lower costs can actually lead to higher import prices in some regions, and price divergence between import regions. Using both a general theoretical...

Gazprom, the dominant gas company in Russia, is widely believed to be the key supplier of gas to Europe in the foreseeable future. However, there are numerous uncertainties and challenges within the Russian and European gas industry that may alter the allocation of Gazprom´s gas sales between...

This paper introduces strategic behavior of the electricity network operator in a congested network with imperfect competition for generation. It models a two stage Stackelberg game. First, the network operator sets transmission prices, then generators set output and sales. Several scenarios for...

Abstract: This paper derives the socially optimal transmission prices in a congested electricity network when there is imperfect competition in generation, and when the budget constraint of the network operator is binding. The results which we derive are a generalization of the standard Ramsey...

Groundwater is an important source of freshwater throughout the world. Due to over-exploitation of groundwater over many years, a number of potential adverse hydrogeological problems have raised. To reduce such adverse effects, it is necessary to carry out strict groundwater management in...

This paper presents a water quantity operation scheme to resolve series of environmental problems which some waterfront bodies are faced with, such as frequent water-level fluctuation, sediment deposition, water quality degradation, water transparency depravation, and submerged aquatic plant...

Recent developments in turbine technology allow the extraction of kinetic energy from tidal flows. This method of renewable energy generation is gaining popularity because of the high predictability of tides, the low environmental impact with no land occupation, and the lower investment needed...

This paper presents the evaluation and optimization of a solar desiccant wheel performance. A numerical model is developed to study and discuss the effect of the design parameters such as wheel thickness, wheel speed, regeneration to adsorption area ratio, wheel porosity, and the operating...
