This article touches upon the issue of determining the annual minimum economic operating period of cogeneration units, based on internal combustion engines. The calculation of this important indicator for cogeneration plants was performed for the installed power capacities in the range of 5-3000 kWe under local conditions and is based on the analysis of expenditures and revenues. The developed economic...
With the expansion of renewable energy's contribution to the energy mix, balancing the electricity grid is becoming increasingly challenging. Alongside other solutions, Power-to-Hydrogen concepts are gaining significant interest. In this paper, the “Task 38”, initiated by the Hydrogen Implementing Agreement of the International Energy Agency, presents the first of a two-step literature review regarding...
We assessed the technical and economic viability of small-scale plants producing “drop-in replacement” transportation fuels from non-food biomass and capturing and storing byproduct CO2 in spent shale-gas wells. Additional designs considered co-processing of natural gas — the least carbon-intensive fossil fuel — to increase liquid-fuel yields and plant efficiency, with some penalty in greenhouse gas...
An apparent transformation of energy trade in developing countries such as the UAE directly impacts and influences the global energy dynamics. UAE is the largest global exporter of fossil fuel for energy generation and it is therefore a necessity to analyze the regional in-house energy market as a first from the demand-side improvement perspective. Due to the arid climatic nature of the country, we...
At present, many countries are aware of the global warming crisis which is resulted from the pollution of fossil fuels, therefore, the alternative energy especially solar energy is needed to decrease reliance on conventional energy source. In Thailand, solar photovoltaic (PV) rooftops have promoted by the government to install in the private household. After reviewing, this paper presents factors...
Data centers represent a large load for the grid, and the number of data centers are increasing at a high rate. The transmission network in the grid is becoming congested as a result of the load growth. Data centers have underutilized energy resources, such as backup generators and battery storage, which can be used for demand response (DR) to benefit both the electric power system and the data center...
Our previous research has shown that distributed storage capacity at load centers (e.g. deferrable demand) can lower total system costs by smoothing out and flattening the daily dispatch profile of conventional generating units. The main savings in cost come from the price arbitrage caused by shifting load and from the reduction in the amount of installed conventional generating capacity needed to...
Lebanon stands to benefit significantly from extracting and monetizing its potential natural gas reserves. However, significant uncertainty has resulted in stakeholders adopting a wait-and-see approach in decision-making and investment in the hydrocarbon sector. This paper aims to address this uncertainty by providing a structured framework to determine the conditions that make various export options...
Future smart grids will require an observable, controllable and flexible network architecture for reliable and efficient energy delivery. The use of artificial intelligence and advanced communication technologies is essential in building a fully automated system. This paper introduces a new technique for online optimal operation of distributed generation (DG) resources, i.e. a hybrid fuel cell (FC)...
The development of reliable energy scenarios are become increasingly more important and crucial due to scientific interest but also because it is essential for the deployment of effective energy policies in the territory. The depletion of Fossil Fuels and the need for the most industrialized countries to achieve the target of a sustainable development have induced important national, European and...
Power-to-Gas can contribute with valuable balancing power and seasonal storage capacity to future power systems. In Portugal, forecasts for 2020 show significant excess of renewable energy generation that can be transformed by power-to-gas technology and fed into the natural gas infrastructure. This work suggests an innovative approach to assess future power-togas integration potentials at the national...
In this article the impact of liquefied natural gas (LNG) imports and shale gas exploitation on a European dependency from main gas suppliers is analysed. For this purpose we introduce the “Gas Market Model (GaMaMod)” that represents the European natural gas market within a bottom-up approach. In order to analyse the European gas supply, we look at two main scenarios for the year 2025 with regard...
Until recently, most natural gas trade has been limited to the regional scale due to the challenges of transporting gas over long distances. Liquefied Natural Gas (LNG) — an option that reduces the volume of gas about 600 times allowing for transportation by ship — has created an opportunity for expansion of the international market for natural gas. Pipeline option shows cost competitiveness for short...
Energy planning is a complex process involving multiple and conflicting objectives with many agents able to influence decisions. This complexity is frequently addressed with the use of multicriteria tools, relying on a set of criteria and different methods to aggregate all the information in a final ranking of the available alternatives. This paper describes the application of a multicriteria decision...
This paper discusses the recent events and trajectory of Unconventional Hydrocarbon (UH) development in Europe and the United States, contrasting the ‘high-politics’ debate on UH with the ‘place-based’ perspectives of locally impacted communities. The unitary frames that dominate official political debates, industry responses and mainstream media texts, bifurcate UH development as an economy versus...
The rapid growth of the auto industry is a major challenge to reduce CO2 emissions in China. Promoting energy-saving" & new energy vehicles should be effective to tackle the issue. This paper aims to evaluate impacts of such promotion on CO2 emission reduction. Scenario analysis method and the Gompertz model are adopted to simulate future auto market scale and structure. Possible emission...
Micro-grids are among the basic components in the future distributed generation smart grid systems. The transmission efficiency improvements and the utilization of renewable energy sources are some of the key advantages of using micro-grids in power systems. In this paper, the technical and economical study of implementing a micro-grid system at an educational institution is discussed and presented...
Offshore wind provides multiple benefits both in terms of economic savings to consumers and reduction in environmental residuals. The current paper uses a state-of-of-the-art software system, pCloudAnalytics™ to evaluate multiple scenarios of the incorporation of offshore wind assets in the New England electric power system ranging in size from 100MW to 1200MW. The analysis is focused...
Energy Commission Malaysia is targeting 4100 MW of power generation capacity via competitive bidding to replace capacity from the 1st generation Power Purchase Agreement (PPA) that will be retired from 2015 to 2017 and to cater for future demand growth. Malaysia's generation mix has been long time dependence on a single fuel. This over-dependency is not a good option for long-term energy sustainability...
Saudi Arabia has ambitious plans for nuclear power. Given this context, this paper examines the economics of nuclear power and compares it to two other sources of electricity, natural gas and solar energy. It calculates the costs of electricity generation, water desalination and the opportunity cost associated with forgone oil and gas revenues. A sensitivity analysis is included to account for variations...
