Cogeneration is the simultaneous production of electricity and heat from a single fuel source in a process. It allows for a more efficient and effective use of valuable primary energy resources when compared with the independent production of electricity and heat. Cogeneration is therefore attractive to both the private sector and policy-makers because it delivers a range of economic benefits and can be an important strategy in meeting greenhouse gas mitigation targets. This article examines the current legal and regulatory treatment of cogeneration in Alberta in the industrial sector. The authors argue that, given the scale and importance of cogeneration to the province’s industrial sector, and to the province generally, it is perhaps time that Alberta developed a clear and coherent policy on cogeneration.

Dams a facility that stores water in the and uses water in a sustainable way. The high use of imported energy resources, which is composed entirely of fossil fuels and which has negative impacts in terms of economic and political aspects, clearly shows that the use and potential of domestic and renewable energy resources is inevitable. Increasing the domestic and renewable primary energy source of hydroelectric energy production to the highest values is only possible with the development of the right tank management policies. Dams also had been built to produce motive power and electricity since the industrial revolution. Development priorities changed, experience accumulated with the construction and operation of dams. Although the importance of water is well known in the human life and civilization around the world, still various groups argue that expected economic benefits are not being produced and that major environmental, economic and social costs are not being taken into account

The article assesses prospects of the Russian-Korean cooperation and analyzes risks and opportunities of the trilateral energy projects on the Korean Peninsula. The author noted that energy sector is the key area of bilateral cooperation between Russia and the Republic of Korea, but it’s mainly represented by the trade in primary energy resources. The study identified the export potential of Russian hydrocarbons to the market of the Republic of Korea. As for the DPRK, the paper shows that within bilateral relations geopolitical interests prevail over the economic ones. The small capacity of the DPRK's domestic market and the absence of fixation sources do not allow considering it as an independent full-fledged market for the Russian energy resources. The main goal of the energy strategy of Russia and the Russian Far East is increasing the volume of exports of the primary energy resources to the APR countries. Russian prospects for the new product niches in the energy markets of the Republic of Korea are associated with the implementation of trilateral energy projects among Russia, the DPRK and the Republic of Korea. It includes creation of the interstate power transmission lines and construction of a gas pipeline. All parties are interested in these projects. As for Russia, it is primarily the expansion of energy exports, including occupation of the commodity niches in new markets, and strengthening of the political role in the region. As for the Republic of Korea, these projects mean diversification of supplies and costs’ reduction of the import energy resources. And as for the DPRK, these projects imply an additional source of financing (as payment for transit), improvement of the country's energy infrastructure and reduction of the deficit of energy resources. Despite the prospects, the author determined that in the near future implementation of the projects is unlikely due to the unresolved transit risks.

In the recent years, there has been a surge in artisanal and small-scale gold mining (ASGM) in various districts of Malawi. Reports of a gold rush have emerged in various districts, including Mangochi, Lilongwe, Balaka, and lately in Kasungu. There has been persistence by many indigenous communities participating in ASGM activities, yet little is being done by the government to formalize and support the sub-sector. The purpose of this study was to investigate the benefits of artisanal small-scale gold mining in Malawi and expose the shortfalls so that key stakeholders and policy makers are well informed. A quantitative approach which used semi-structured questionnaires was used and the data was analyzed using Microsoft excel and Statistical Packages for the Social Sciences (SPSS). The study shows that ASGM is characterized by people with low literacy levels, who use traditional tools (low-tech) and use methods fueled by lack of capital, and deficiency of basic knowledge of mining and geology. The study found that the government could achieve substantial socio-economic development from the sector by: (1) revising the current artisanal and small-scale mining (ASM) legislation so that it embraces the customary practices whilst safeguarding the environment and improving the tax collection base; (2) providing support in form of mining related training and education to these communities; (3) leading in transfer of modern technologies for improved extraction; (4) supporting ASM cooperatives in securing credit facilities from financial institutions; and (5) closing the existing knowledge gap for ASM related issues through introduction of mining desk officers in district councils.

This paper deals with the problem of energy utilization efficiency evaluation of a microturbine system for Combined Cooling, Heating and Power production (CCHP). The CCHP system integrates power generation, cooling and heating, which is a type of total energy system on the basis of energy cascade utilization principle, and has a large potential of energy saving and economical efficiency. A typical CCHP system has several options to fulfill energy requirements of its application, the electrical energy can be produced by a gas turbine, the heat can be generated by the waste heat of a gas turbine, and the cooling load can be satisfied by an absorption chiller driven by the waste heat of a gas turbine. The energy problem of the CCHP system is so large and complex that the existing engineering cannot provide satisfactory solutions. The decisive values for energetic efficiency evaluation of such systems are the primary energy generation cost. In this paper, in order to reveal internal essence of CCHP, we have analyzed typical CCHP systems and compared them with individual systems. The optimal operation of this system is dependent upon load conditions to be satisfied. The results indicate that CCHP brings 38.7 percent decrease in energy consumption comparing with the individual systems. A CCHP system saves fuel resources and has the assurance of economic benefits. Moreover, two basic CCHP models are presented for determining the optimum energy combination for the CCHP system with 100kW microturbine, and the more practical performances of various units are introduced, then Primary Energy Ratio (PER) and exergy efficiency (α) of various types and sizes systems are analyzed. Through exergy comparison performed for two kinds of CCHP systems, we have identified the essential principle for high performance of the CCHP system, and consequently pointed out the promising features for further development.

Natural Photosynthesis

Demand for energy is projected to increase at least twofold by mid-century relative to the present global consumption because of predicted population and economic growth. This demand could be met, in principle, from fossil energy resources, particularly coal. However, the cumulative nature of carbon dioxide (CO 2 ) emissions demands that stabilizing the atmospheric CO 2 levels to just twice their pre-anthropogenic values by mid-century will be extremely challenging, requiring invention, development and deployment of schemes for carbon-neutral energy production on a scale commensurate with, or larger than, the entire present-day energy supply from all sources combined. Among renewable and exploitable energy resources, nuclear fusion energy or solar energy are by far the largest. However, in both cases, technological breakthroughs are required with nuclear fusion being very difficult, if not impossible on the scale required. On the other hand, 1 h of sunlight falling on our planet is equivalent to all the energy consumed by humans in an entire year. If solar energy is to be a major primary energy source, then it must be stored and despatched on demand to the end user. An especially attractive approach is to store solar energy in the form of chemical bonds as occurs in natural photosynthesis. However, a technology is needed which has a year-round average conversion efficiency significantly higher than currently available by natural photosynthesis so as to reduce land-area requirements and to be independent of food production. Therefore, the scientific challenge is to construct an ‘artificial leaf’ able to efficiently capture and convert solar energy and then store it in the form of chemical bonds of a high-energy density fuel such as hydrogen while at the same time producing oxygen from water. Realistically, the efficiency target for such a technology must be 10 per cent or better. Here, we review the molecular details of the energy capturing reactions of natural photosynthesis, particularly the water-splitting reaction of photosystem II and the hydrogen-generating reaction of hydrogenases. We then follow on to describe how these two reactions are being mimicked in physico-chemical-based catalytic or electrocatalytic systems with the challenge of creating a large-scale robust and efficient artificial leaf technology.

The VIRTUS project aims to create a Virtual Power Plant (VPP) prototype coordinating the Distributed Energy Resources (DERs) of the power system and providing services to the system operators and the various players of the electricity markets, with a particular focus on the industrial sector agents. The VPP will be able to manage a significant number of DERs and simulate realistic plants, components, and market data to study different operating conditions and the future impact of the policy changes of the Balancing Markets (BM). This paper describes the project’s aim, the general structure of the proposed framework, and its optimization and simulation modules. Then, we assess the scalability of the optimization module, designed to provide the maximum possible flexibility to the system operators, exploiting the simulation module of the VPP.

The natural gas consuming sectors in Bangladesh are: i) Power, ii) Fertilizer, iii) Industry, iv) Captive power, v) Domestic, vi) Commercial, and vii) Transportation (CNG). Broad sectoral consumptions are reported in various literatures and reports, however, further breakdown of the data are difficult to find, and neither reported. The combined consumption of fertilizer, industry and captive power sectors is a significant portion of national gas consumption. This paper presents for the first time an in-depth analysis of the industrial sector gas consumption. Data were collected for each type of industry, and grouped according to the United Nations Framework Convention for Climate Change (UNFCCC). Captive generation is included in the industrial sector consumption, unlike the usual practice of considering it under the power generation. It is noticed that garments, textile and leather industries together have shown remarkable growth in the last decade. All the industries are more or less related to the national GDP growth. Some are export oriented while others address the internal market. Therefore analysis presented here should be helpful for policy makers to prioritize the sectors in case preferential supply and tariff adjustments become necessary.DOI: http://dx.doi.org/10.3329/jce.v27i1.15846 Journal of Chemical Engineering, IEB Vol. ChE. 27, No. 1, June 2012: 1-7

Financing Infrastructure

Private sector investment opportunities in Africa’s infrastructure are huge. Regulatory reforms across African countries are identified as critical to the realization of the expected investment flows in the infrastructure sector. However, planners and policy makers need to note that there are infrastructure deficiencies in all subsectors with low income countries (LICs) in Africa facing the greatest challenge. Inefficiencies in implementing infrastructure projects account for USD 17 billion annually and improving the capacity of African countries will help minimize these costs. In this regard, the donor community must play a greater role in African LICs while innovative financing mechanisms must be the focus in the relatively richer countries of the continent. Traditional sources of financing infrastructure development remain important but private investment is critical in closing the current gaps. Countries need to devise mechanisms to exploit opportunities and avoid pitfalls in investing in infrastructure.
