LNG supply for Lebanon's power sector in light of the pending offshore gas discoveries and the world's falling oil prices

Abstract: This paper investigates the viability of an LNG import infrastructure and a coastal pipeline interconnecting most of the countries' power plants. The analysis is performed in light of the pending offshore gas discoveries and the world's falling oil prices. The methodology used in this research is based on a probabilistic approach through the development of an integrated energy-economics appraisal-model that uses a probabilistic Fuel Demand Module (FDM) which is derived from a traditional production-costing approach. The developed energy model is interrelated to an investment feasibility model used to assess the financial feasibility of the terminal. This two-folded paper provides a proposal to concatenate an FDM to the traditional probabilistic production-costing model, which is an effective tool for the financial appraisal of a typical fuel infrastructure. The other fold is the technical and commercial aspects that are considered advantageous to the country's policy makers.

Geological model for the Menai Strait tunnel

Abstract: A 400 kV electricity transmission line is required to cross the Menai Strait to connect the proposed Wylfa Newydd nuclear power station on Ynys Mon (also known as Anglesey) with the mainland. Through an initial feasibility study, the preferred Menai Strait crossing option has been shown to require the construction of a tunnel. This region has a complex geological history, where the oldest strata, consisting of schist and tuff deposits, are interpreted as Precambrian. There are also Carboniferous bedrocks of interbedded limestones, mudstones and sandstones, and Ordovician siltstones and quartzite sandstones. The superficial deposits and landforms are understood to be almost entirely the signature of the last Devensian glaciation, except for occasional deposits and landforms resulting from fluctuations in sea-level. A 3D geological model has been created using published geological records and project-specific surveys, including field surveys, rock exposure mapping, ground investigations and geophysical surveys. This allows the visualization of the anticipated geology of the area, the identification of geological hazards and efficient design and planning for construction.

Wind Energy Technologies for Distributed Power

Abstract: This paper is an industrial update on the development of wind energy conversion systems (WECS). It highlights the two major types of wind turbines: horizontal axis and vertical axis. To enhance the integration and deployment of wind technologies, advancements in their operation have been developed specifically with regard to enhanced efficiency, making them more robust and less susceptible to wind variations. This paper encapsulates the various power ratings available in the range of 10 kW to 1 MW while providing manufacturer and technical details of such topologies. The paper also considers the future requirement potential of wind energy technology.
