The impact of potential climate policy on the coal bed methane investment in China - a real option–based study
In this paper, based on the real option theory, the impact of the potential climate policy on the coal bed methane (CBM) investment in China is assessed from the perspective of CBM investment under the uncertainties of future climate policy and CBM market price. The threshold values of the market and policy variables to promote CBM project investment are obtained. Firstly, incorporating the ...

Influence and control of coal facies on physical properties of the coal reservoirs in Western Guizhou and Eastern Yunnan, China
Western Guizhou and Eastern Yunnan have abundant coal resources, and they are considered as the most prospective areas for coalbed methane (CBM) development in Southern China. To explore the potential of CBM production in these areas, this paper identifies the plane distribution of coal facies, and analyses its control on the physical properties of coal reservoirs. Four types of coal facies ...

Collaborative business modelling for systemic and sustainability innovations
Sustainability innovations are characterised by a systemic nature and require that multiple organisations act in an orchestrated fashion. To jointly identify opportunities and plan sustainability innovations, new methods and approaches are needed. In this article, we describe a case study where eight firms have collaborated to envision and create new business models in the energy industry. After ...

A review of the three most popular maintenance systems: how well is the energy sector represented?
A recent review of maintenance literature found that total productive maintenance (TPM), reliability–centred maintenance (RCM), and condition–based maintenance (CBM) were the most popular maintenance management models discussed in academic journals. In this paper, a comprehensive review of these three models is undertaken to identify empirical 'real world' examples of each model being used in ...

A comparative study of the characteristics of coalbed methane reservoirs in the Zhina region, Guizhou Province and the Southern Qinshui Basin, Shanxi Province, China
In order to explore the coalbed methane recovery potential of the Zhina region in the Southwest China, this paper compared the physical properties of coal reservoirs in the Zhina region and the successfully developed Southern Qinshui Basin. The results show that the pore structures of the coal samples in the two areas are dominated by adsorption pores, which is favourable for the accumulation of ...

Growth and properties of the dilute bismide semiconductor GaAs1−xBix a complementary alloy to the dilute nitrides
In this review we describe the growth and properties of the dilute bismide semiconductor alloy GaAs1−xBix and show how its properties are in certain respects complementary to the dilute nitride alloy, GaNyAs1−y. Like the dilute nitrides the dilute bismides show a giant band gap bowing effect in which a small concentration of the alloying element has a disproportionate effect on the band gap, ...

What projects will have a pivotal role to ensure China’s energy security?
Interview with Shan Weiguo, Head of Gas Market Research at CNPC. This is the second part of a two-part interview. Read the first part here. Gastech News: What projects will have a pivotal role to ensure China’s energy security? Shan Weiguo: There are many projects. The most important one is dealing with the infrastructure, especially the import facilities: the pipelines and LNG terminals. ...

Recovering coal bed methane from deep unmineable coal seams and carbon sequestration
Published data from nearly 2,000 coal samples comprising 250 coal beds from 17 states, representing many of the coal producing horizons in the USA, shows moderate correlation (0.7) between depth and methane content for high volatile coal ranks. Low-volatile rank coals average the highest methane content, 12.74 m?/ton (450 ft?/ton), subbituminous rank coals the lowest, Keywords: CO2 sequestration, ...

A review of non–renewable energy options in Illinois
The State of Illinois has the largest non–renewable (fossil) energy reserves among all the states in the USA. We report our studies on coal, oil and gas energy resources, conversions, consumptions and carbon dioxide sequestration advances in Illinois from the point of view of sustainability in energy and environmental. This includes reserves and characteristics of coal, oil and gas in the ...

Generation using gas-fuelled engines in South Africa – an overview
Most gas engines are Otto cycle spark ignition internal combustion reciprocating engines using natural gas as the primary fuel. Smaller models utilise stochiometric combustion while the larger engines are lean burn engines with pre-chamber ignition systems. The engines are coupled with packaged generator sets, cogeneration and, even, trigeneration units to optimise energy utilisation in the fuel ...

Biomethane enters the gas grid article for energy world
The Carbon Plan, published in 2011, aims to reduce UK carbon emissions by a quarter from 1990 levels. With the current policies in place, the UK is on target to reduce emissions by over a third by 2020 and with the introduction of new technologies this should increase to an 80% reduction by 2050. However, currently around half the UK’s carbon emissions result from heat related processes and ...
