Floating Liquefied Natural Gas (FLNG) units combine gas pre-treatment to tight specifications and natural gas liquefaction that are new to offshore with traditional production systems that are commonly found on oil Floating Production Storage and Offloading (FPSO) vessels. Attention is often focused on the new units, sometimes forgetting that successful operation of the Liquefied Natural Gas (L...

This paper summarizes the Next Generation Natural Gas Vehicle (NG-NGV) Program that is led by the U.S. Department Of Energy’s (DOE’s) Office of Heavy Vehicle Technologies (OHVT) through the National Renewable Energy Laboratory (NREL). The goal of this program is to develop and implement one Class 3-6 compressed natural gas (CNG) prototype vehicle and one Class 7-8 liquefied natural gas (LNG) pr...

This paper presents a model of multimarket competition with capacity investments. A firm which serves a single market enjoys a strategic advantage over a multimarket rival. It “overinvests”recognizing that its rival can deploy capacity to another market. The focused firm, due to the specificity of its investment, has no such “outside option”. The model shows how lower costs and a sharper focus ...

Current interest in the shipment of liquefied natural gas (LNG) has renewed the debate about the safety of shipping large volumes of flammable fuels. The size of a spreading pool following a release of LNG from an LNG tank ship has been the subject of numerous papers and studies dating back to the mid-1970s. Several papers have presented idealized views of how the LNG would be released and spre...

Liquefied natural gas (LNG) projects are regulated by host countries, but policy and regulation should depend on geography and meteorology. Without considering the role of geography and meteorology, sub-optimal design choices can result, leading to energy conversion efficiency and capital investment decisions that are less than ideal. A key step in LNG is regasification, which transforms LNG ba...

Abstract We explore the relationship between Liquified Natural Gas (LNG) and Petroleum (LPG) carrier freight rates global geopolitical risk, while also controlling for macro environment. Our results show that a shock in risk significantly increases cost of spot charter both LNG LPG carriers, with impact reaching around 25% former 18% latter. bear significant implications companies countries inv...

Exergy analysis is important and has been widely used to evaluate the thermodynamic efficiency of a variety of processes. Therefore, there is a need to develop a tool for monitoring exergy of a process in real-time and for studying the effects of various feed, equipment, process and environmental changes. The ultimate aim of this work is to develop a tool to enable dynamic and online exergy ana...

In this work, energy and exergy analyses are carried out for a combined cycle consisting of an organic Rankine cycle (ORC) and a liquefied natural gas (LNG) Rankine cycle for the recovery of low-grade heat sources and LNG cold energy. The effects of the turbine inlet pressure and the working fluid on the system performance are theoretically investigated. A modified temperature-enthalpy diagram ...

This paper analyzes corporate strategies in the emerging global market for liquefied natural gas (LNG). In particular, we provide an empirical analysis of the determinants driving companies towards increasing vertical integration leading to an industry in which a small number of large and powerful players are active. Our hypothesis of high transaction costs along the LNG value chain inducing a ...

This paper presents a generic, high-level risk assessment of the global operation of ocean-going liquefied natural gas (LNG) carriers. The analysis collects and combines information from several sources such as an initial hazid, a thorough review of historic LNG accidents, review of previous studies, published damage statistics and expert judgement, and develops modular risk models for critical...
