Case studies from two Nigerian hydrocarbon processing industries, where gas turbine generators (GTG) were used for power generation were analyzed. The first study analyzed a simple cycle power generation where the GTG produced 25 MW of electricity and three separately fired boilers produced the required process steam. The second study analyzed a combined cycle (cogeneration) where the same GTG that produced 25 MW of electricity also generated 90700 Kg/hr of steam from the turbine exhaust gas. The study shows that cogeneration (combined cycle) satisfied all the electric power and steam requirements of the plant. Simple cycle only satisfied the electric power requirement. Other disadvantages of simple cycle show that over 60% of the generated energy is lost to the environment in form of heat. A loss in production worth over $6,182,400 as a result of failure in a separately fired boiler was calculated. The study concludes that cogeneration must be undertaken with an awareness of energy system expansion, generation costs and the need for industrial energy consumption of a given plant.

To support the propulsion and electrical requirements of an all-electric CVX, the use of heavy-duty power generation gas turbines could be considered as a viable alternative to conventional steam propulsion. A 300 MWe total plant baseload capacity is needed for an all-electric ship requiring 200 MWe for propulsion and a peak electric catapult power requirement of 200 MWe. Applications of advanced marine gas turbines to provide electric power to an all-electric CVX have a major advantage in that the gas turbines do not have to be located in the same area as the electric propulsion motors. The possibility of locating the turbine-generators topside to minimize the ship impacts associated with long runs of large intake and exhaust ducts was briefly studied and is discussed herein.

Energy Network

The “International Clean Energy System Technology Utilizing Hydrogen (World Energy Network)”: WE-NET is a research program directed at the development of the technologies needed build a hydrogen-based energy conversion system. It proposes to set up a world energy network to convert renewable energy, such as hydropower and solar energy, into a secondary and transportable form to supply the demand centers, and to make possible the utilization of existing power generation, transportation, town gas, etc. Within the framework of this program Mitsubishi Heavy Industries, Hitachi and Westinghouse Power Corporation are working to develop an hydrogen-fueled combustion turbine system designed to meet the goals set by the WE-NET Program. The hydrogen–fueled power generation cycle will be able to satisfy the requirements of an efficiency based on the lower heating value higher than 70% and of reliability, availability and maintainability equivalent to current base-loaded natural gas-fired combined cycle. The use of hydrogen will eliminate emissions of CO2 and SOx and significantly reduce those of NOx. This paper presents a thermodynamic analysis of some concepts of hydrogen fuelled cycles which have been studied in the WE-NET program and makes a comparison of their performance.

Structure Adjustment

In this study, in order to improve regional energy system adjustment, a multistage stochastic inexact robust programming (MSIRP) is proposed for electric-power generation planning and structure adjustment management under uncertainty. Scenario-based inexact multistage stochastic programming and stochastic robust optimization were integrated into general programming to reflect uncertainties that were expressed as interval values and probability distributions in the objective function and constraints. An MSIRP-based energy system optimization model is proposed for electric-power structure management of Zibo City in Shandong Province, China. Three power demand scenarios associated with electric-power structure adjustment, imported electricity, and emission reduction were designed to obtain multiple decision schemes for supporting regional sustainable energy system development. The power generation schemes, imported electricity, and emissions of CO2 and air pollutants were analyzed. The results indicated that the model can effectively not only provide a more stable energy supply strategies and electric-power structure adjustment schemes, but also improve the balanced development between conventional and new clear power generation technologies under uncertainty.

The use of gas turbine and combined cycle power plants for thermal and electric power generation is, nowadays, a consolidated technology. Moreover, the employment of combined heat and power production, especially for low power requirements, is constantly increasing. In this scenario, below ambient pressure discharge gas turbine (BAGT) is an innovative and interesting application; the hot gases discharged from a gas turbine may be expanded below ambient pressure to obtain an increase in electric power generation. The gases are then cooled to supply heat to the thermal utility and finally recompressed to the ambient pressure. The power plant cogenerative performance depends on the heat and electric demand that usually varies during the year (for residential heating the heat to electric power ratio may range from 0.3 to 9). In this paper, the thermal load variation influence on the BAGT performance will be investigated and compared with those of gas turbine and combined cycle power plants.
