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.

Power Generation Cycle

This paper considers the issue of associated petroleum gas utilization during hydrocarbon production in remote petroleum fields. Due to the depletion of conventional oil and gas deposits around the globe, production shifts to hard-to-recover resources, such as heavy and high-viscosity oil that requires a greater amount of energy to be recovered. At the same time, large quantities of associated petroleum gas are extracted along with the oil. The gas can be utilized as a fuel for power generation. However, even the application of combined power modes (combined heat and power and combined cooling heat and power) cannot guarantee full utilization of the associated petroleum gas. Analysis of the electrical and heat loads’ graphs of several oil fields revealed that the generated thermal energy could not always be fully used. To improve the efficiency of the fuel’s energy potential conversion, an energy system with a binary power generation cycle was developed, consisting of two power installations—a main gas microturbine and an auxiliary steam turbine unit designed to power the technological objects in accordance with the enterprise’s power load charts. To provide for the most complete utilization of associated petroleum gas, a gas-to-liquid system is introduced, which converts the rest of the gas into synthetic liquid hydrocarbons that are used at the field. Processing of gas into various products also lowers the carbon footprint of the petroleum production. Application of an energy system with a binary power generation cycle makes it possible to achieve an electrical efficiency up to 55%, at the same time maintaining high efficiency of consumers’ energy supply during the year. The utilization of the associated petroleum gas in the developed system can reach 100%.

Refuse Incineration

The objectives of this paper are to develop a combined power generation cycle using refuse incineration and LNG cold energy, and to conduct parametric analysis to investigate the effects of key parameters on the thermal and exergy efficiencies. The combined cycle consists of an ammonia–water Rankine cycle with refuse incinerator and a LNG cold energy cycle with use of regasified LNG as the extra fuel in the incinerator. The combined cycle is compared with the conventional steam Rankine cycle.

Power Generation Cycle

Most of the potable water and electricity are produced by dual purpose plants. Dual-purpose plants are the one that supplies heat for a thermal desalination unit and produces electricity for distribution to the electrical grid. In this paper a power plant is combined with a multi-effect evaporation thermal vapor compression (METVC) system. Compared with the most widely used (Multi Stage Flash) MSF desalination, METVC has more advantages. Then, energy and exergy analysis equations for desalination plant, power generation cycle, heat recovery steam generator and combined power and water cycle are developed and the results are presented. Results show by rising number of effect from 2 to 14, performance ratio, exergy efficiency and specific heat transfer area rise steadily. For combined system, the maximum and minimum values of exergy destruction rate are related to combustion chamber and desalination effects, respectively. Also, with increasing TIT, exergy destruction rate of power generation cycle decreases while the exergy destruction rate of METVC, especially thermo compressor, goes up and fresh water production reduces dramatically.

Set Up

The Clean Energy Resource Teams (CERTs) is a project designed to give local citizens and other stakeholders a voice in planning and determining their energy future. In total, there are seven CERTs operating in seven regions across Minnesota, USA. CERTs connect citizens with technical expertise to facilitate planning and implementation of energy conservation and renewable energy projects. These technical resources are helping the teams identify and prioritize the most appropriate and cost-effective opportunities within their regions. This paper will describe one of these energy teams (the Northeast CERT) and its efforts in promoting clean energy production and conservation. A key product of the Northeast CERT is a strategic energy plan that highlights the region's top energy priorities. As part of its project priorities, the Northeast Minnesota CERT is working to set up demonstration projects at every school and community in the region. Toward this goal, the team is currently collaborating with two schools in the region to set up renewable energy projects such as wind and solar, which in turn would help students to understand that renewables and conservation can and should be an integral part of our energy system.

In this paper, a method of magnetoelectricity power generation system for vehicle on the downhill of expressways is proposed. This system is a clean energy system that can be reused. Its structure includes car magnetic poles, magnetic poles imbedded in road surface, closed circuit imbedded in road surface, rectifier, inverter and storage battery. Multi-unit magnetic poles and closed circuits imbedded in the road surface are used in this invention, so when the car poles move with the running down of cars on downhill, magnetic flow in closed circuits will change to produce a technique of group control power generation. From the simulated system in the test, it can be seen that it is efficient and effective in generating power.
