Abundant availability and potential for lower CO2 emissions are drivers for increased utilization of natural gas in automotive engines for transportation applications. However scarce refueling resources for on-road vehicles impose an infrastructure limited barrier on natural gas use in transportation. A novel ‘bimodal’ engine which can operate in a compressor mode has been developed that allows...

a value chain is a series of events that takes a raw material and with each step adds value to it. global interest in the application of natural gas (ng) in production and transportation has grown dramatically, representing a long-term, low-cost, domestic, and secure alternative to petroleum-based fuels. many technological solutions are currently considered on the market or in development, whic...

Natural gas hydrates are solid hydrogen-bonded water crystals containing small molecular gases. The amount of natural gas stored as hydrates in permafrost and ocean sediments is twice that of all other fossil fuels combined. However, hydrate blockages also hinder oil/gas pipeline transportation, and, despite their huge potential as energy sources, our insufficient understanding of hydrates has ...

• The transportation and consumption of oil and natural gas in the continental United States may be directly affected by new regulations and legislation, including (1) the Clean Power Plan proposed by the U.S. Environmental Protection Agency (EPA), (2) railcar rules proposed by the U.S. Department of Transportation (DOT), and (3) proposed laws related to the controversial Keystone XL Pipeline e...

In this paper, an Ant Colony Optimization Algorithm (ACO) is proposed for operations of steady flow gas pipeline. The system is composed of compressing stations linked by pipe legs. The decisions variables are chosen to be the operating turbo compressor number and the discharge pressure for each compressing station. The objective function is the power consumed in the system by these stations. U...

This paper proposes a method based on genetic algorithm (GA) for the security-constrained 11 optimal dispatch of integrated natural gas and electricity networks, considering operating scenarios 12 in both energy systems. The mathematical formulation of the optimization problem consists of a 13 multi-objective function which aims to minimize both cost of thermal generation (diesel and natural 14...
