Abstract

Purpose

With the growing climate problem, it has become a consensus to develop low-carbon technologies to reduce emissions. Electric industry is a major carbon-emitting industry, accounting for 35% of global carbon emissions. Universities, as an important patent application sector in China, promote their patent application and transformation to enhance Chinese technological innovation capability. This study aims to analyze low-carbon electricity technology transformation in Chinese universities.

Design/methodology/approach

This paper uses IncoPat to collect patent data. The trend of low-carbon electricity technology patent applications in Chinese universities, the status, patent technology distribution, patent transformation status and patent transformation path of valid patent is analyzed.

Findings

Low-carbon electricity technology in Chinese universities has been promoted, and the number of patents has shown rapid growth. Invention patents proportion is increasing, and the transformation has become increasingly active. Low-carbon electricity technology in Chinese universities is mainly concentrated in individual cooperative patent classification (CPC) classification numbers, and innovative technologies will be an important development for electric reduction.

Originality/value

This paper innovatively uses valid patents to study the development of low-carbon electricity technology in Chinese universities, and defines low-carbon technology patents by CPC patent classification system. A new attempt focuses on the development status and direction in low-carbon electricity technology in Chinese universities, and highlights the contribution of valid patents to patent value.

Abstract

Purpose

This study aims to present preliminary results from an integrated evaluation of electricity supply systems for rural areas using renewable energy technologies by means of a multi‐objective decision making method

Design/methodology/approach

Goal programming is applied to obtain the optimal system configuration meeting the electricity demand, based on the location's resource availability and taking diesel generation as the alternative of reference. The performance of the system is evaluated through four attributes: electricity generation costs, employment and two environmental impacts (CO2 emissions and land use). The model is designed for isolated rural area belonging to the non‐interconnected zones of Colombia.

Findings

Application of the method showed that biomass conversion technology has the highest potential and that renewable energy systems offer better performance than diesel generation. Reductions of more than 10 percent in unit electricity costs, land use rates and CO2 emissions can be achieved.

Research limitations/implications

Inclusion of additional attributes and sensitivity analysis are matters of future research.

Originality/value

The methodology used in this study is an alternative means to perform evaluation of electricity supply systems integrating several aspects of technology and which is flexible enough so as to enable the inclusion of a wider scope of interests towards energy access targets.

Abstract

The role of management control has not received sufficient attention in the literature on value creation so far. Therefore, this paper aims to investigate the role of control in value creation in industrial networks. More specifically, the aim is to examine the management and control of interfaces between key resources within and between firms, in the networks surrounding firms, when they attempt to create value. All the firms that take part in a value-creation process have both formal and informal control systems: these firms have budgets, specific routines, reward systems, and sanctioned “ways to behave.” The paper relates the Industrial Marketing and Purchasing (IMP) group's research on interaction, relationships, and networks with control literature, and presents a framework for controlling resource interfaces in a network setting. Two in-depth cases illustrate the role of control in value creation. The first case covers the development of a low-weight newspaper grade that Holmen and its paper mill Hallsta initiated. The second case examines the attempt to develop and commercialize a new, energy efficient pulping technology.

Abstract

Purpose

The purpose of this study is to formulate the most probable future scenario for the use of blockchain technology within the next 5–10 years in the electricity sector based on today’s experts’ views.

Design/methodology/approach

An international, two-stage Delphi study with 20 projections is used.

Findings

According to the experts, blockchain applications will be primarily based on permissioned or consortium blockchains. Blockchain-based applications will integrate Internet of Things devices in the power grid, manage the e-mobility infrastructure, automate billing and direct payment and issue certificates regarding the origin of electricity. Blockchain solutions are expected to play an important big role in fostering peer-to-peer trading in microgrids, further democratizing and decentralizing the energy sector. New regulatory frameworks become necessary.

Research limitations/implications

The Delphi study’s scope is rather broad than narrow and detailed. Further studies should focus on partial scenarios.

Practical implications

Electricity market participants should build blockchain-based competences and collaborate in current pilot projects.

Social implications

Blockchain technology will further decentralize the energy sector and probably reduce transaction costs.

Originality/value

Despite the assumed importance of blockchain technology, no coherent foresight study on its use and implications exists yet. This study closes this research gap.

Abstract

Purpose

The national governments of the European Union (EU) are finding it increasingly difficult to provide their populations with cheap and reliable sources of electricity. There is a highly controversial technology available within the EU which could overcome this problem – nuclear generated electricity. The purpose of this article is to question the extent to which it is possible to reconcile the views of those citizens who object to the use of nuclear electricity with views of those who support the use of nuclear electricity as a competitive, sustainable and secure electricity supply within an open and competitive European energy market.

Design/methodology/approach

This article adopts an inter‐disciplinary approach to the analysis of the issues.

Findings

Political, economic and environmental pressures are combining to constrain the opportunities for national governments to enable citizens’ preferences with regard to the nuclear sector to be maintained. What is argued in the article is that all the tools which are available to the EU to overcome any lack of democratic decision making in the nuclear sector must be utilised to their full potential, including the legal framework provided by the often overlooked EURATOM Treaty.

Originality/value

The research will be of value to academic lawyers and political scientists investigating the problematic relationships which exist between the national and supranational levels of governance in the EU.

Abstract

Purpose

The purpose of this paper is to examine and discuss, in-depth, how solar electricity can be developed and used to tackle grid electricity-related problems in African countries suffering from unreliable and inadequate grid electricity.

Design/methodology/approach

The paper discusses in depth the current status of grid electricity in Africa continent and suggested solar electricity as an alternative cost-effective method to the existing grid electricity problem in remote areas. An extensive analysis of the major contribution of solar electricity in various sectors such as economic, health, communication, social and environmental benefits is provided. The paper concludes with a discussion on how solar power generation can be developed.

Findings

The paper shows that in developed countries where ICT has been applied extensively, ICT offers increased opportunities for sustainable economic development and plays a critical role in rapid economic growth, productive capacity improvements, education, government, agriculture and international competitiveness enhancement. The paper has pointed out that ICT has yet to make significant impact in most African countries due to lack of reliable and adequate electricity. Solar electricity has been seen as the most cost-effective way of generating electricity, especially in remote rural areas, for ICT devices. For the widespread of solar power generation in Africa, various strategies have been identified which include training of qualified solar engineers and technicians, establishing PV markets and business modes, introduction of solar energy education in schools and universities, political leaders appreciating solar electricity as one of the major energy component, lowering initial cost of the PV technology, availability of finance mechanisms for rural communities, import tax exemption and African countries regarding rural electricity as one of the basic needs.

Practical implications

The paper shows that the problems of lack of qualified solar technicians and established PV markets and business modes (especially in remote areas), lack of solar energy education in schools have to be addressed before the benefits of ICT in Africa can be seen. Other issues include African countries appreciating solar electricity as one of the major energy component, lowering initial cost of the PV technology, availability of finance mechanisms for customers, import tax exemption and African countries regarding rural electricity as one of the basic needs like food, shelter and clothing. Overhaul of existing systems needs to take place in order to provide the means to deal with some of these issues.

Originality/value

Availability of reliable electrical energy remains crucial for development of ICT in rural African countries. Solar electricity is clearly one of the most promising prospects to the grid electricity problem in African countries because most African countries lie in the sunshine belt. The paper raises awareness about this in a unique way and suggests some novel measures about increasing the availability of solar systems for solar power generation. It is anticipated that the increases in solar power generation, especially in remote areas, will increase the use and application of ICT in various sectors.

Abstract

Purpose

The purpose of this paper is to elaborate a multi‐criteria methodology for the performance assessment of energy supply technologies, which also takes into account the dynamics of technological change.

Design/methodology/approach

The approach chosen is based on the multi‐criteria outranking methodology Preference Ranking Organisation METHod for Enrichment Evaluations (PROMETHEE), which is linked to the concept of technology's life cycle by assigning criteria weights depending on the actual development phase of a certain technology. The modifications to the PROMETHEE algorithm are described and the modified methodology is demonstrated by evaluating heat and power supply alternatives for a municipal area in Germany.

Findings

The methodology is suitable for the evaluation of energy technologies taking into account varying preferences depending on their stage of maturity. It is a feasible alternative to other methodologies which allow for interconnections like the analytic network process. The results show that, based on a multi‐criteria life cycle approach, renewable energy technologies are competitive with conventional alternatives for supplying heat and power.

Practical implications

Appropriate methods are required to elicit life cycle‐dependent preferences. Decision support should help decision makers (DMs) to articulate preferences according to different development phases and illustrate the results in the most meaningful way.

Originality/value

The methodology provides the basis for a comprehensive analysis of energy technologies at different life cycle stages. It can be used to support decision making in different situations and by various actors.

Abstract

Purpose

The purpose of this paper is to provide a long‐term assessment of Pakistan's electricity policy in the context of both environmental and resource constraints. To increase the sustainability of energy supply, the Government of Pakistan introduced a series of reforms in the electricity supply sector during 1990‐1995. In response to these policy incentives, most of the independent power producer offers included coal, oil, and/or gas‐based power plants. Considering that Pakistan produces only up to 40 percent of its oil demand domestically and thermal power generation causes CO2 emissions, there is a great need for an assessment of the existing electricity policy.

Design/methodology/approach

Drawing on system dynamics methodology, this study presents and utilizes a dynamic simulation model that captures the dynamics of the sectors underlying the electricity supply system including investments, capital, production, resources, financial resources, and the environment.

Findings

The key findings of this study are: policy incentives encouraged thermal‐based generation at the potential expense of hydro power generation; and the evolution of electricity supply related CO2 emissions exhibits an exponential growth.

Research limitations/implications

While there are other emissions related to the electricity supply system with potentially severe environmental concerns, for example SO2, this study focuses only on CO2 emissions.

Originality/value

The paper offers a system dynamics model and provides some useful policy insights for the electricity supply sector of Pakistan.

Abstract

Purpose

Energy has a strategic role in the social and economic development of countries. Affordability, accessibility and availability of energy sources are the priorities of the governments in energy supply. Therefore, understanding the robustness of energy supply is an important subject of energy researchers and policymakers. This paper aims to analyze the robustness of the electricity system at the national level.

Design/methodology/approach

First, the strengths, weaknesses, opportunities and threats analysis is implemented for a selected case study. Then, the expert panel weighed the parameters’ effect on sustainable power generation, the survey is quantified using fuzzy logic. Finally, cross functional analysis is applied to evaluate the influence/dependence of the parameters.

Findings

The results show three determinant parameters which have the most influence on the system: fluctuations in oil prices, governmental acts and sanctions against the country. The most dependent parameters, as objectives variables, are the share of renewables and distributed generation (DG), system reliability, power generation diversity and transmission efficiency.

Originality/value

Using future studies methods in the energy level at the nation level has been done for the first time in the current work.
